  • How can I limit the number of registrants to an event?

    - by user356900
    I've set up a basic html/php submission form where people can register for our event, but need a way to replace the submission form webpage with one that reads something like "We have reached our registration limit" when we reach a certain number of submitted forms. Our database is MySQL (if that makes a difference) I've looked around on the web but people either say to count the entries by hand, or the ones that do have an automated system use CMS like drupal or joomla. Is it possible to setup an automated script that will do this?

  • Custom ASP.NET Routing to an HttpHandler

    - by Rick Strahl
    As of version 4.0 ASP.NET natively supports routing via the now built-in System.Web.Routing namespace. Routing features are automatically integrated into the HtttpRuntime via a few custom interfaces. New Web Forms Routing Support In ASP.NET 4.0 there are a host of improvements including routing support baked into Web Forms via a RouteData property available on the Page class and RouteCollection.MapPageRoute() route handler that makes it easy to route to Web forms. To map ASP.NET Page routes is as simple as setting up the routes with MapPageRoute:protected void Application_Start(object sender, EventArgs e) { RegisterRoutes(RouteTable.Routes); } void RegisterRoutes(RouteCollection routes) { routes.MapPageRoute("StockQuote", "StockQuote/{symbol}", "StockQuote.aspx"); routes.MapPageRoute("StockQuotes", "StockQuotes/{symbolList}", "StockQuotes.aspx"); } and then accessing the route data in the page you can then use the new Page class RouteData property to retrieve the dynamic route data information:public partial class StockQuote1 : System.Web.UI.Page { protected StockQuote Quote = null; protected void Page_Load(object sender, EventArgs e) { string symbol = RouteData.Values["symbol"] as string; StockServer server = new StockServer(); Quote = server.GetStockQuote(symbol); // display stock data in Page View } } Simple, quick and doesn’t require much explanation. If you’re using WebForms most of your routing needs should be served just fine by this simple mechanism. Kudos to the ASP.NET team for putting this in the box and making it easy! How Routing Works To handle Routing in ASP.NET involves these steps: Registering Routes Creating a custom RouteHandler to retrieve an HttpHandler Attaching RouteData to your HttpHandler Picking up Route Information in your Request code Registering routes makes ASP.NET aware of the Routes you want to handle via the static RouteTable.Routes collection. You basically add routes to this collection to let ASP.NET know which URL patterns it should watch for. You typically hook up routes off a RegisterRoutes method that fires in Application_Start as I did in the example above to ensure routes are added only once when the application first starts up. When you create a route, you pass in a RouteHandler instance which ASP.NET caches and reuses as routes are matched. Once registered ASP.NET monitors the routes and if a match is found just prior to the HttpHandler instantiation, ASP.NET uses the RouteHandler registered for the route and calls GetHandler() on it to retrieve an HttpHandler instance. The RouteHandler.GetHandler() method is responsible for creating an instance of an HttpHandler that is to handle the request and – if necessary – to assign any additional custom data to the handler. At minimum you probably want to pass the RouteData to the handler so the handler can identify the request based on the route data available. To do this you typically add  a RouteData property to your handler and then assign the property from the RouteHandlers request context. This is essentially how Page.RouteData comes into being and this approach should work well for any custom handler implementation that requires RouteData. It’s a shame that ASP.NET doesn’t have a top level intrinsic object that’s accessible off the HttpContext object to provide route data more generically, but since RouteData is directly tied to HttpHandlers and not all handlers support it it might cause some confusion of when it’s actually available. Bottom line is that if you want to hold on to RouteData you have to assign it to a custom property of the handler or else pass it to the handler via Context.Items[] object that can be retrieved on an as needed basis. It’s important to understand that routing is hooked up via RouteHandlers that are responsible for loading HttpHandler instances. RouteHandlers are invoked for every request that matches a route and through this RouteHandler instance the Handler gains access to the current RouteData. Because of this logic it’s important to understand that Routing is really tied to HttpHandlers and not available prior to handler instantiation, which is pretty late in the HttpRuntime’s request pipeline. IOW, Routing works with Handlers but not with earlier in the pipeline within Modules. Specifically ASP.NET calls RouteHandler.GetHandler() from the PostResolveRequestCache HttpRuntime pipeline event. Here’s the call stack at the beginning of the GetHandler() call: which fires just before handler resolution. Non-Page Routing – You need to build custom RouteHandlers If you need to route to a custom Http Handler or other non-Page (and non-MVC) endpoint in the HttpRuntime, there is no generic mapping support available. You need to create a custom RouteHandler that can manage creating an instance of an HttpHandler that is fired in response to a routed request. Depending on what you are doing this process can be simple or fairly involved as your code is responsible based on the route data provided which handler to instantiate, and more importantly how to pass the route data on to the Handler. Luckily creating a RouteHandler is easy by implementing the IRouteHandler interface which has only a single GetHttpHandler(RequestContext context) method. In this method you can pick up the requestContext.RouteData, instantiate the HttpHandler of choice, and assign the RouteData to it. Then pass back the handler and you’re done.Here’s a simple example of GetHttpHandler() method that dynamically creates a handler based on a passed in Handler type./// <summary> /// Retrieves an Http Handler based on the type specified in the constructor /// </summary> /// <param name="requestContext"></param> /// <returns></returns> IHttpHandler IRouteHandler.GetHttpHandler(RequestContext requestContext) { IHttpHandler handler = Activator.CreateInstance(CallbackHandlerType) as IHttpHandler; // If we're dealing with a Callback Handler // pass the RouteData for this route to the Handler if (handler is CallbackHandler) ((CallbackHandler)handler).RouteData = requestContext.RouteData; return handler; } Note that this code checks for a specific type of handler and if it matches assigns the RouteData to this handler. This is optional but quite a common scenario if you want to work with RouteData. If the handler you need to instantiate isn’t under your control but you still need to pass RouteData to Handler code, an alternative is to pass the RouteData via the HttpContext.Items collection:IHttpHandler IRouteHandler.GetHttpHandler(RequestContext requestContext) { IHttpHandler handler = Activator.CreateInstance(CallbackHandlerType) as IHttpHandler; requestContext.HttpContext.Items["RouteData"] = requestContext.RouteData; return handler; } The code in the handler implementation can then pick up the RouteData from the context collection as needed:RouteData routeData = HttpContext.Current.Items["RouteData"] as RouteData This isn’t as clean as having an explicit RouteData property, but it does have the advantage that the route data is visible anywhere in the Handler’s code chain. It’s definitely preferable to create a custom property on your handler, but the Context work-around works in a pinch when you don’t’ own the handler code and have dynamic code executing as part of the handler execution. An Example of a Custom RouteHandler: Attribute Based Route Implementation In this post I’m going to discuss a custom routine implementation I built for my CallbackHandler class in the West Wind Web & Ajax Toolkit. CallbackHandler can be very easily used for creating AJAX, REST and POX requests following RPC style method mapping. You can pass parameters via URL query string, POST data or raw data structures, and you can retrieve results as JSON, XML or raw string/binary data. It’s a quick and easy way to build service interfaces with no fuss. As a quick review here’s how CallbackHandler works: You create an Http Handler that derives from CallbackHandler You implement methods that have a [CallbackMethod] Attribute and that’s it. Here’s an example of an CallbackHandler implementation in an ashx.cs based handler:// RestService.ashx.cs public class RestService : CallbackHandler { [CallbackMethod] public StockQuote GetStockQuote(string symbol) { StockServer server = new StockServer(); return server.GetStockQuote(symbol); } [CallbackMethod] public StockQuote[] GetStockQuotes(string symbolList) { StockServer server = new StockServer(); string[] symbols = symbolList.Split(new char[2] { ',',';' },StringSplitOptions.RemoveEmptyEntries); return server.GetStockQuotes(symbols); } } CallbackHandler makes it super easy to create a method on the server, pass data to it via POST, QueryString or raw JSON/XML data, and then retrieve the results easily back in various formats. This works wonderful and I’ve used these tools in many projects for myself and with clients. But one thing missing has been the ability to create clean URLs. Typical URLs looked like this: http://www.west-wind.com/WestwindWebToolkit/samples/Rest/StockService.ashx?Method=GetStockQuote&symbol=msfthttp://www.west-wind.com/WestwindWebToolkit/samples/Rest/StockService.ashx?Method=GetStockQuotes&symbolList=msft,intc,gld,slw,mwe&format=xml which works and is clear enough, but also clearly very ugly. It would be much nicer if URLs could look like this: http://www.west-wind.com//WestwindWebtoolkit/Samples/StockQuote/msfthttp://www.west-wind.com/WestwindWebtoolkit/Samples/StockQuotes/msft,intc,gld,slw?format=xml (the Virtual Root in this sample is WestWindWebToolkit/Samples and StockQuote/{symbol} is the route)(If you use FireFox try using the JSONView plug-in make it easier to view JSON content) So, taking a clue from the WCF REST tools that use RouteUrls I set out to create a way to specify RouteUrls for each of the endpoints. The change made basically allows changing the above to: [CallbackMethod(RouteUrl="RestService/StockQuote/{symbol}")] public StockQuote GetStockQuote(string symbol) { StockServer server = new StockServer(); return server.GetStockQuote(symbol); } [CallbackMethod(RouteUrl = "RestService/StockQuotes/{symbolList}")] public StockQuote[] GetStockQuotes(string symbolList) { StockServer server = new StockServer(); string[] symbols = symbolList.Split(new char[2] { ',',';' },StringSplitOptions.RemoveEmptyEntries); return server.GetStockQuotes(symbols); } where a RouteUrl is specified as part of the Callback attribute. And with the changes made with RouteUrls I can now get URLs like the second set shown earlier. So how does that work? Let’s find out… How to Create Custom Routes As mentioned earlier Routing is made up of several steps: Creating a custom RouteHandler to create HttpHandler instances Mapping the actual Routes to the RouteHandler Retrieving the RouteData and actually doing something useful with it in the HttpHandler In the CallbackHandler routing example above this works out to something like this: Create a custom RouteHandler that includes a property to track the method to call Set up the routes using Reflection against the class Looking for any RouteUrls in the CallbackMethod attribute Add a RouteData property to the CallbackHandler so we can access the RouteData in the code of the handler Creating a Custom Route Handler To make the above work I created a custom RouteHandler class that includes the actual IRouteHandler implementation as well as a generic and static method to automatically register all routes marked with the [CallbackMethod(RouteUrl="…")] attribute. Here’s the code:/// <summary> /// Route handler that can create instances of CallbackHandler derived /// callback classes. The route handler tracks the method name and /// creates an instance of the service in a predictable manner /// </summary> /// <typeparam name="TCallbackHandler">CallbackHandler type</typeparam> public class CallbackHandlerRouteHandler : IRouteHandler { /// <summary> /// Method name that is to be called on this route. /// Set by the automatically generated RegisterRoutes /// invokation. /// </summary> public string MethodName { get; set; } /// <summary> /// The type of the handler we're going to instantiate. /// Needed so we can semi-generically instantiate the /// handler and call the method on it. /// </summary> public Type CallbackHandlerType { get; set; } /// <summary> /// Constructor to pass in the two required components we /// need to create an instance of our handler. /// </summary> /// <param name="methodName"></param> /// <param name="callbackHandlerType"></param> public CallbackHandlerRouteHandler(string methodName, Type callbackHandlerType) { MethodName = methodName; CallbackHandlerType = callbackHandlerType; } /// <summary> /// Retrieves an Http Handler based on the type specified in the constructor /// </summary> /// <param name="requestContext"></param> /// <returns></returns> IHttpHandler IRouteHandler.GetHttpHandler(RequestContext requestContext) { IHttpHandler handler = Activator.CreateInstance(CallbackHandlerType) as IHttpHandler; // If we're dealing with a Callback Handler // pass the RouteData for this route to the Handler if (handler is CallbackHandler) ((CallbackHandler)handler).RouteData = requestContext.RouteData; return handler; } /// <summary> /// Generic method to register all routes from a CallbackHandler /// that have RouteUrls defined on the [CallbackMethod] attribute /// </summary> /// <typeparam name="TCallbackHandler">CallbackHandler Type</typeparam> /// <param name="routes"></param> public static void RegisterRoutes<TCallbackHandler>(RouteCollection routes) { // find all methods var methods = typeof(TCallbackHandler).GetMethods(BindingFlags.Instance | BindingFlags.Public); foreach (var method in methods) { var attrs = method.GetCustomAttributes(typeof(CallbackMethodAttribute), false); if (attrs.Length < 1) continue; CallbackMethodAttribute attr = attrs[0] as CallbackMethodAttribute; if (string.IsNullOrEmpty(attr.RouteUrl)) continue; // Add the route routes.Add(method.Name, new Route(attr.RouteUrl, new CallbackHandlerRouteHandler(method.Name, typeof(TCallbackHandler)))); } } } The RouteHandler implements IRouteHandler, and its responsibility via the GetHandler method is to create an HttpHandler based on the route data. When ASP.NET calls GetHandler it passes a requestContext parameter which includes a requestContext.RouteData property. This parameter holds the current request’s route data as well as an instance of the current RouteHandler. If you look at GetHttpHandler() you can see that the code creates an instance of the handler we are interested in and then sets the RouteData property on the handler. This is how you can pass the current request’s RouteData to the handler. The RouteData object also has a  RouteData.RouteHandler property that is also available to the Handler later, which is useful in order to get additional information about the current route. In our case here the RouteHandler includes a MethodName property that identifies the method to execute in the handler since that value no longer comes from the URL so we need to figure out the method name some other way. The method name is mapped explicitly when the RouteHandler is created and here the static method that auto-registers all CallbackMethods with RouteUrls sets the method name when it creates the routes while reflecting over the methods (more on this in a minute). The important point here is that you can attach additional properties to the RouteHandler and you can then later access the RouteHandler and its properties later in the Handler to pick up these custom values. This is a crucial feature in that the RouteHandler serves in passing additional context to the handler so it knows what actions to perform. The automatic route registration is handled by the static RegisterRoutes<TCallbackHandler> method. This method is generic and totally reusable for any CallbackHandler type handler. To register a CallbackHandler and any RouteUrls it has defined you simple use code like this in Application_Start (or other application startup code):protected void Application_Start(object sender, EventArgs e) { // Register Routes for RestService CallbackHandlerRouteHandler.RegisterRoutes<RestService>(RouteTable.Routes); } If you have multiple CallbackHandler style services you can make multiple calls to RegisterRoutes for each of the service types. RegisterRoutes internally uses reflection to run through all the methods of the Handler, looking for CallbackMethod attributes and whether a RouteUrl is specified. If it is a new instance of a CallbackHandlerRouteHandler is created and the name of the method and the type are set. routes.Add(method.Name,           new Route(attr.RouteUrl, new CallbackHandlerRouteHandler(method.Name, typeof(TCallbackHandler) )) ); While the routing with CallbackHandlerRouteHandler is set up automatically for all methods that use the RouteUrl attribute, you can also use code to hook up those routes manually and skip using the attribute. The code for this is straightforward and just requires that you manually map each individual route to each method you want a routed: protected void Application_Start(objectsender, EventArgs e){    RegisterRoutes(RouteTable.Routes);}void RegisterRoutes(RouteCollection routes) { routes.Add("StockQuote Route",new Route("StockQuote/{symbol}",                     new CallbackHandlerRouteHandler("GetStockQuote",typeof(RestService) ) ) );     routes.Add("StockQuotes Route",new Route("StockQuotes/{symbolList}",                     new CallbackHandlerRouteHandler("GetStockQuotes",typeof(RestService) ) ) );}I think it’s clearly easier to have CallbackHandlerRouteHandler.RegisterRoutes() do this automatically for you based on RouteUrl attributes, but some people have a real aversion to attaching logic via attributes. Just realize that the option to manually create your routes is available as well. Using the RouteData in the Handler A RouteHandler’s responsibility is to create an HttpHandler and as mentioned earlier, natively IHttpHandler doesn’t have any support for RouteData. In order to utilize RouteData in your handler code you have to pass the RouteData to the handler. In my CallbackHandlerRouteHandler when it creates the HttpHandler instance it creates the instance and then assigns the custom RouteData property on the handler:IHttpHandler handler = Activator.CreateInstance(CallbackHandlerType) as IHttpHandler; if (handler is CallbackHandler) ((CallbackHandler)handler).RouteData = requestContext.RouteData; return handler; Again this only works if you actually add a RouteData property to your handler explicitly as I did in my CallbackHandler implementation:/// <summary> /// Optionally store RouteData on this handler /// so we can access it internally /// </summary> public RouteData RouteData {get; set; } and the RouteHandler needs to set it when it creates the handler instance. Once you have the route data in your handler you can access Route Keys and Values and also the RouteHandler. Since my RouteHandler has a custom property for the MethodName to retrieve it from within the handler I can do something like this now to retrieve the MethodName (this example is actually not in the handler but target is an instance pass to the processor): // check for Route Data method name if (target is CallbackHandler) { var routeData = ((CallbackHandler)target).RouteData; if (routeData != null) methodToCall = ((CallbackHandlerRouteHandler)routeData.RouteHandler).MethodName; } When I need to access the dynamic values in the route ( symbol in StockQuote/{symbol}) I can retrieve it easily with the Values collection (RouteData.Values["symbol"]). In my CallbackHandler processing logic I’m basically looking for matching parameter names to Route parameters: // look for parameters in the routeif(routeData != null){    string parmString = routeData.Values[parameter.Name] as string;    adjustedParms[parmCounter] = ReflectionUtils.StringToTypedValue(parmString, parameter.ParameterType);} And with that we’ve come full circle. We’ve created a custom RouteHandler() that passes the RouteData to the handler it creates. We’ve registered our routes to use the RouteHandler, and we’ve utilized the route data in our handler. For completeness sake here’s the routine that executes a method call based on the parameters passed in and one of the options is to retrieve the inbound parameters off RouteData (as well as from POST data or QueryString parameters):internal object ExecuteMethod(string method, object target, string[] parameters, CallbackMethodParameterType paramType, ref CallbackMethodAttribute callbackMethodAttribute) { HttpRequest Request = HttpContext.Current.Request; object Result = null; // Stores parsed parameters (from string JSON or QUeryString Values) object[] adjustedParms = null; Type PageType = target.GetType(); MethodInfo MI = PageType.GetMethod(method, BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic); if (MI == null) throw new InvalidOperationException("Invalid Server Method."); object[] methods = MI.GetCustomAttributes(typeof(CallbackMethodAttribute), false); if (methods.Length < 1) throw new InvalidOperationException("Server method is not accessible due to missing CallbackMethod attribute"); if (callbackMethodAttribute != null) callbackMethodAttribute = methods[0] as CallbackMethodAttribute; ParameterInfo[] parms = MI.GetParameters(); JSONSerializer serializer = new JSONSerializer(); RouteData routeData = null; if (target is CallbackHandler) routeData = ((CallbackHandler)target).RouteData; int parmCounter = 0; adjustedParms = new object[parms.Length]; foreach (ParameterInfo parameter in parms) { // Retrieve parameters out of QueryString or POST buffer if (parameters == null) { // look for parameters in the route if (routeData != null) { string parmString = routeData.Values[parameter.Name] as string; adjustedParms[parmCounter] = ReflectionUtils.StringToTypedValue(parmString, parameter.ParameterType); } // GET parameter are parsed as plain string values - no JSON encoding else if (HttpContext.Current.Request.HttpMethod == "GET") { // Look up the parameter by name string parmString = Request.QueryString[parameter.Name]; adjustedParms[parmCounter] = ReflectionUtils.StringToTypedValue(parmString, parameter.ParameterType); } // POST parameters are treated as methodParameters that are JSON encoded else if (paramType == CallbackMethodParameterType.Json) //string newVariable = methodParameters.GetValue(parmCounter) as string; adjustedParms[parmCounter] = serializer.Deserialize(Request.Params["parm" + (parmCounter + 1).ToString()], parameter.ParameterType); else adjustedParms[parmCounter] = SerializationUtils.DeSerializeObject( Request.Params["parm" + (parmCounter + 1).ToString()], parameter.ParameterType); } else if (paramType == CallbackMethodParameterType.Json) adjustedParms[parmCounter] = serializer.Deserialize(parameters[parmCounter], parameter.ParameterType); else adjustedParms[parmCounter] = SerializationUtils.DeSerializeObject(parameters[parmCounter], parameter.ParameterType); parmCounter++; } Result = MI.Invoke(target, adjustedParms); return Result; } The code basically uses Reflection to loop through all the parameters available on the method and tries to assign the parameters from RouteData, QueryString or POST variables. The parameters are converted into their appropriate types and then used to eventually make a Reflection based method call. What’s sweet is that the RouteData retrieval is just another option for dealing with the inbound data in this scenario and it adds exactly two lines of code plus the code to retrieve the MethodName I showed previously – a seriously low impact addition that adds a lot of extra value to this endpoint callback processing implementation. Debugging your Routes If you create a lot of routes it’s easy to run into Route conflicts where multiple routes have the same path and overlap with each other. This can be difficult to debug especially if you are using automatically generated routes like the routes created by CallbackHandlerRouteHandler.RegisterRoutes. Luckily there’s a tool that can help you out with this nicely. Phill Haack created a RouteDebugging tool you can download and add to your project. The easiest way to do this is to grab and add this to your project is to use NuGet (Add Library Package from your Project’s Reference Nodes):   which adds a RouteDebug assembly to your project. Once installed you can easily debug your routes with this simple line of code which needs to be installed at application startup:protected void Application_Start(object sender, EventArgs e) { CallbackHandlerRouteHandler.RegisterRoutes<StockService>(RouteTable.Routes); // Debug your routes RouteDebug.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes); } Any routed URL then displays something like this: The screen shows you your current route data and all the routes that are mapped along with a flag that displays which route was actually matched. This is useful – if you have any overlap of routes you will be able to see which routes are triggered – the first one in the sequence wins. This tool has saved my ass on a few occasions – and with NuGet now it’s easy to add it to your project in a few seconds and then remove it when you’re done. Routing Around Custom routing seems slightly complicated on first blush due to its disconnected components of RouteHandler, route registration and mapping of custom handlers. But once you understand the relationship between a RouteHandler, the RouteData and how to pass it to a handler, utilizing of Routing becomes a lot easier as you can easily pass context from the registration to the RouteHandler and through to the HttpHandler. The most important thing to understand when building custom routing solutions is to figure out how to map URLs in such a way that the handler can figure out all the pieces it needs to process the request. This can be via URL routing parameters and as I did in my example by passing additional context information as part of the RouteHandler instance that provides the proper execution context. In my case this ‘context’ was the method name, but it could be an actual static value like an enum identifying an operation or category in an application. Basically user supplied data comes in through the url and static application internal data can be passed via RouteHandler property values. Routing can make your application URLs easier to read by non-techie types regardless of whether you’re building Service type or REST applications, or full on Web interfaces. Routing in ASP.NET 4.0 makes it possible to create just about any extensionless URLs you can dream up and custom RouteHanmdler References Sample ProjectIncludes the sample CallbackHandler service discussed here along with compiled versionsof the Westwind.Web and Westwind.Utilities assemblies.  (requires .NET 4.0/VS 2010) West Wind Web Toolkit includes full implementation of CallbackHandler and the Routing Handler West Wind Web Toolkit Source CodeContains the full source code to the Westwind.Web and Westwind.Utilities assemblies usedin these samples.

  • Asterisk SIP digest authentication username mismatch

    - by Matt
    I have an asterisk system that I'm attempting to get to work as a backup for our 3com system. We already use it for a conference bridge. Our phones are the 3com 3C10402B, so I don't have the issue of older 3com phones that come without a SIP image. The 3com phones are communicating SIP with the Asterisk, but are unable to register because they present a digest username value that doesn't match what Asterisk thinks it should. As an example, here are the relevant lines from a successful registration from a soft phone: Server sends: WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="1cac3853" Phone responds: Authorization: Digest username="2321", realm="asterisk", nonce="1cac3853", uri="sip:192.168.254.12", algorithm=md5, response="d32df9ec719817282460e7c2625b6120" For the 3com phone, those same lines look like this (and fails): Server sends: WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="6c915c33" Phone responds: Authorization: Digest username="sip:[email protected]", realm="asterisk", nonce="6c915c33", uri="sip:192.168.254.12", opaque="", algorithm=MD5, response="a89df25f19e4b4598595f919dac9db81" Basically, Asterisk wants to see a username in the Digest username field of 2321, but the 3com phone is sending sip:[email protected]. Anyone know how to tell asterisk to accept this format of username in the digest authentication? Here is the sip.conf info for that extension: [2321] deny=0.0.0.0/0.0.0.0 disallow=all type=friend secret=1234 qualify=yes port=5060 permit=0.0.0.0/0.0.0.0 nat=yes mailbox=2321@device host=dynamic dtmfmode=rfc2833 dial=SIP/2321 context=from-internal canreinvite=no callerid=device <2321 allow=ulaw, alaw call-limit=50 ... and for those interested in the grit, here is the debug output of the registration attempt: REGISTER sip:192.168.254.12 SIP/2.0 v: SIP/2.0/UDP 192.168.254.157:5060 t: f: i: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18580 REGISTER Max-Forwards: 70 m: ;dt=544 Expires: 3600 User-Agent: 3Com-SIP-Phone/V8.0.1.3 X-3Com-PhoneInfo: firstRegistration=no; primaryCallP=192.168.254.12; secondaryCallP=0.0.0.0; --- (11 headers 0 lines) --- Using latest REGISTER request as basis request Sending to 192.168.254.157 : 5060 (no NAT) SIP/2.0 100 Trying Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18580 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Contact: Content-Length: 0 SIP/2.0 401 Unauthorized Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: ;tag=as3fb867e2 Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18580 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="6c915c33" Content-Length: 0 Scheduling destruction of SIP dialog 'fa4451d8-01d6-1cc2-13e4-00e0bb33beb9' in 32000 ms (Method: REGISTER) confbridge*CLI REGISTER sip:192.168.254.12 SIP/2.0 v: SIP/2.0/UDP 192.168.254.157:5060 t: f: i: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18581 REGISTER Max-Forwards: 70 m: ;dt=544 Expires: 3600 User-Agent: 3Com-SIP-Phone/V8.0.1.3 Authorization: Digest username="sip:[email protected]", realm="asterisk", nonce="6c915c33", uri="sip:192.168.254.12", opaque="", algorithm=MD5, response="a89df25f19e4b4598595f919dac9db81" X-3Com-PhoneInfo: firstRegistration=no; primaryCallP=192.168.254.12; secondaryCallP=0.0.0.0; --- (12 headers 0 lines) --- Using latest REGISTER request as basis request Sending to 192.168.254.157 : 5060 (NAT) SIP/2.0 100 Trying Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18581 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Contact: Content-Length: 0 SIP/2.0 403 Authentication user name does not match account name Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: ;tag=as3fb867e2 Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18581 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Content-Length: 0 Scheduling destruction of SIP dialog 'fa4451d8-01d6-1cc2-13e4-00e0bb33beb9' in 32000 ms (Method: REGISTER) Thanks for your input!

  • Cisco PIX 8.0.4, static address mapping not working?

    - by Bill
    upgrading a working Pix running 5.3.1 to 8.0.4. The memory/IOS upgrade went fine, but the 8.0.4 configuration is not quite working 100%. The 5.3.1 config on which it was based is working fine. Basically, I have three networks (inside, outside, dmz) with some addresses on the dmz statically mapped to outside addresses. The problem seems to be that those addresses can't send or receive traffic from the outside (Internet.) Stuff on the DMZ that does not have a static mapping seems to work fine. So, basically: Inside - outside: works Inside - DMZ: works DMZ - inside: works, where the rules allow it DMZ (non-static) - outside: works But: DMZ (static) - outside: fails Outside - DMZ: fails (So, say, udp 1194 traffic to .102, http to .104) I suspect there's something I'm missing with the nat/global section of the config, but can't for the life of me figure out what. Help, anyone? The complete configuration is below. Thanks for any thoughts! !

  • postfix relaying all mail through office365 problems

    - by amrith
    This is a rather long question with a long list of things tried and travails so please bear with me. The summary is this. I am able to relay email from ubuntu through office365 using postfix; the configuration works. It only works as one of the users; more specifically the user who authenticates against office365 is the only valid "from" More details follow. I have a machine in Amazon's cloud on which I run a bunch of jobs and would like to have statuses mailed over to me. I use office365 at work so I want to relay mail through office365. I'm most familiar with postfix so I used that as the MTA. Configuration is ubuntu 12.04LTS; I've installed postfix and mail-utils. For this example, let me say my company is "company.com" and the machine in question (through an elastic IP and a DNS entry) is called "plaything.company.com". hostname is set to "plaything.company.com", so is /etc/mailname On plaything, I have the following users registered alpha, bravo, and charlie. I have the following configuration files. alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no config_directory = /etc/postfix inet_interfaces = all inet_protocols = ipv4 mailbox_size_limit = 0 mydestination = plaything.company.com, localhost.company.com, , localhost myhostname = plaything.company.com mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 myorigin = /etc/mailname readme_directory = no recipient_delimiter = + relayhost = [smtp.office365.com]:587 sender_canonical_maps = hash:/etc/postfix/sender_canonical smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = noanonymous smtp_sasl_tls_security_options = noanonymous smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtp_use_tls = yes smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_use_tls = yes As the machine is called plaything.company.com I went through the exercise of registering all the appropriate DNS entries to make office365 recognize that I owned plaything.company.com and allowed me to create a user called [email protected] in office365. In office365, I setup [email protected] as having another email address of [email protected]. Then, I made the following sender_canonical [email protected] [email protected] I created a sasl_passwd file that reads: smtp.office365.com [email protected]:123456password123456 let's just say that the password for [email protected] is 1234...456 With all this setup, login as alpha and mail [email protected] Cc: Subject: test test and the whole thing works wonderfully. email gets sent off by postfix, TLS works like a champ, authenticates as daemon@... and [email protected] in Office365 gets an email message. The issue comes up when logged in as bravo to the machine. sender is [email protected] and office365 says: status=bounced (host smtp.office365.com[132.245.12.25] said: 550 5.7.1 Client does not have permissions to send as this sender (in reply to end of DATA command)) this is because I'm trying to send mail as bravo@... and authenticating with office365 as daemon@.... The reason it works with alpha@... is because in office365, I setup [email protected] as having another email address of [email protected]. In Postfix Relay to Office365, Miles Erickson answers the question thusly: Don't send mail to Office365 as a user from your Office365-hosted e-mail domain. Use a subdomain instead, e.g. [email protected] instead of [email protected]. It wouldn't hurt to set up an SPF record for services.mydomain.com or whatever you decide to use. Don't authenticate against mail.messaging.microsoft.com as an Office365 user. Just connect on port 25 and deliver the mail to your domain as any foreign SMTP agent would do. OK, I've done #1, I have those records on DNS but for the most part they are not relevant once Office365 recognizes that I own the domain. Here are those records: CNAME records: - msoid.plaything.company.com - autodiscover.plaything.company.com MX record: - plaything.company.com (plaything-company-com.mail.protection.outlook.com) TXT record: - plaything.company.com (v=spf1 include:spf.protection.outlook.com -all) I've tried #2 but no matter what I do, office365 just blows away the connection with "not authenticated". I can try even a simple telnet to port 25 and attempt to send and it doesn't work. 250 BY2PR01CA007.outlook.office365.com Hello [54.221.245.236] 530 5.7.1 Client was not authenticated Connection closed by foreign host. Is there someone out there who has this kind of a configuration working where multiple users on a linux machine are able to relay mail using postfix through office365? There has to be someone out there doing this who can tell me what is wrong with my setup ...

  • Asterisk SIP digest authentication username mismatch

    - by Matt
    I have an asterisk system that I'm attempting to get to work as a backup for our 3com system. We already use it for a conference bridge. Our phones are the 3com 3C10402B, so I don't have the issue of older 3com phones that come without a SIP image. The 3com phones are communicating SIP with the Asterisk, but are unable to register because they present a digest username value that doesn't match what Asterisk thinks it should. As an example, here are the relevant lines from a successful registration from a soft phone: Server sends: WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="1cac3853" Phone responds: Authorization: Digest username="2321", realm="asterisk", nonce="1cac3853", uri="sip:192.168.254.12", algorithm=md5, response="d32df9ec719817282460e7c2625b6120" For the 3com phone, those same lines look like this (and fails): Server sends: WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="6c915c33" Phone responds: Authorization: Digest username="sip:[email protected]", realm="asterisk", nonce="6c915c33", uri="sip:192.168.254.12", opaque="", algorithm=MD5, response="a89df25f19e4b4598595f919dac9db81" Basically, Asterisk wants to see a username in the Digest username field of 2321, but the 3com phone is sending sip:[email protected]. Anyone know how to tell asterisk to accept this format of username in the digest authentication? Here is the sip.conf info for that extension: [2321] deny=0.0.0.0/0.0.0.0 disallow=all type=friend secret=1234 qualify=yes port=5060 permit=0.0.0.0/0.0.0.0 nat=yes mailbox=2321@device host=dynamic dtmfmode=rfc2833 dial=SIP/2321 context=from-internal canreinvite=no callerid=device <2321 allow=ulaw, alaw call-limit=50 ... and for those interested in the grit, here is the debug output of the registration attempt: REGISTER sip:192.168.254.12 SIP/2.0 v: SIP/2.0/UDP 192.168.254.157:5060 t: f: i: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18580 REGISTER Max-Forwards: 70 m: ;dt=544 Expires: 3600 User-Agent: 3Com-SIP-Phone/V8.0.1.3 X-3Com-PhoneInfo: firstRegistration=no; primaryCallP=192.168.254.12; secondaryCallP=0.0.0.0; --- (11 headers 0 lines) --- Using latest REGISTER request as basis request Sending to 192.168.254.157 : 5060 (no NAT) SIP/2.0 100 Trying Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18580 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Contact: Content-Length: 0 SIP/2.0 401 Unauthorized Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: ;tag=as3fb867e2 Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18580 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="6c915c33" Content-Length: 0 Scheduling destruction of SIP dialog 'fa4451d8-01d6-1cc2-13e4-00e0bb33beb9' in 32000 ms (Method: REGISTER) confbridge*CLI REGISTER sip:192.168.254.12 SIP/2.0 v: SIP/2.0/UDP 192.168.254.157:5060 t: f: i: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18581 REGISTER Max-Forwards: 70 m: ;dt=544 Expires: 3600 User-Agent: 3Com-SIP-Phone/V8.0.1.3 Authorization: Digest username="sip:[email protected]", realm="asterisk", nonce="6c915c33", uri="sip:192.168.254.12", opaque="", algorithm=MD5, response="a89df25f19e4b4598595f919dac9db81" X-3Com-PhoneInfo: firstRegistration=no; primaryCallP=192.168.254.12; secondaryCallP=0.0.0.0; --- (12 headers 0 lines) --- Using latest REGISTER request as basis request Sending to 192.168.254.157 : 5060 (NAT) SIP/2.0 100 Trying Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18581 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Contact: Content-Length: 0 SIP/2.0 403 Authentication user name does not match account name Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: ;tag=as3fb867e2 Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18581 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Content-Length: 0 Scheduling destruction of SIP dialog 'fa4451d8-01d6-1cc2-13e4-00e0bb33beb9' in 32000 ms (Method: REGISTER) Thanks for your input!

  • Postfix configuration - Uing virtual min but server is bouncing back my mail.

    - by brodiebrodie
    I have no experience in setting up postfix, and thought virtualmin minght do the legwork for me. Appears not. When I try to send mail to the domain (either [email protected] [email protected] or [email protected]) I get the following message returned This is the mail system at host dedq239.localdomain. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to <postmaster> If you do so, please include this problem report. You can delete your own text from the attached returned message. The mail system <[email protected]> (expanded from <[email protected]>): User unknown in virtual alias table Final-Recipient: rfc822; [email protected] Original-Recipient: rfc822;[email protected] Action: failed Status: 5.0.0 Diagnostic-Code: X-Postfix; User unknown in virtual alias table How can I diagnose the problem here? It seems that the mail gets to my server but the server fails to locally deliver the message to the correct user. (This is a guess, truthfully I have no idea what is happening). I have checked my virtual alias table and it seems to be set up correctly (I can post if this would be helpful). Can anyone give me a clue as to the next step?

  • Windows DNS Server 2008 R2 fallaciously returns SERVFAIL

    - by Easter Sunshine
    I have a Windows 2008 R2 domain controller which is also a DNS server. When resolving certain TLDs, it returns a SERVFAIL: $ dig bogus. ; <<>> DiG 9.8.1 <<>> bogus. ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 31919 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;bogus. IN A I get the same result for a real TLD like com. when querying the DC as shown above. Compare to a BIND server that is working as expected: $ dig bogus. @128.59.59.70 ; <<>> DiG 9.8.1 <<>> bogus. @128.59.59.70 ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 30141 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;bogus.

This sounds similar to the issue described in http://support.microsoft.com/kb/968372 except I am using two forwarders (128.59.59.70 from above as well as 128.59.62.10) and falling back to root hints so the preconditions to expose the issue are not the same. Nevertheless, I also applied the MaxCacheTTL registry fix as described and restarted DNS and the whole server as well but the problem persists. The problem occurs on all domain controllers in this domain and has occurred since half a year ago, even though the servers are getting automatic Windows updates. EDIT Here is a debug log. The client is 160.39.114.110, which is my workstation. 1/25/2012 2:16:01 PM 0E08 PACKET 000000001EA6BFD0 UDP Rcv 160.39.114.110 2e94 Q [0001 D NOERROR] A (5)bogus(0) UDP question info at 000000001EA6BFD0 Socket = 508 Remote addr 160.39.114.110, port 49710 Time Query=1077016, Queued=0, Expire=0 Buf length = 0x0fa0 (4000) Msg length = 0x0017 (23) Message: XID 0x2e94 Flags 0x0100 QR 0 (QUESTION) OPCODE 0 (QUERY) AA 0 TC 0 RD 1 RA 0 Z 0 CD 0 AD 0 RCODE 0 (NOERROR) QCOUNT 1 ACOUNT 0 NSCOUNT 0 ARCOUNT 0 QUESTION SECTION: Offset = 0x000c, RR count = 0 Name "(5)bogus(0)" QTYPE A (1) QCLASS 1 ANSWER SECTION: empty AUTHORITY SECTION: empty ADDITIONAL SECTION: empty 1/25/2012 2:16:01 PM 0E08 PACKET 000000001EA6BFD0 UDP Snd 160.39.114.110 2e94 R Q [8281 DR SERVFAIL] A (5)bogus(0) UDP response info at 000000001EA6BFD0 Socket = 508 Remote addr 160.39.114.110, port 49710 Time Query=1077016, Queued=0, Expire=0 Buf length = 0x0fa0 (4000) Msg length = 0x0017 (23) Message: XID 0x2e94 Flags 0x8182 QR 1 (RESPONSE) OPCODE 0 (QUERY) AA 0 TC 0 RD 1 RA 1 Z 0 CD 0 AD 0 RCODE 2 (SERVFAIL) QCOUNT 1 ACOUNT 0 NSCOUNT 0 ARCOUNT 0 QUESTION SECTION: Offset = 0x000c, RR count = 0 Name "(5)bogus(0)" QTYPE A (1) QCLASS 1 ANSWER SECTION: empty AUTHORITY SECTION: empty ADDITIONAL SECTION: empty Every option in the debug log box was checked except "filter by IP". By contrast, when I query, say, accounts.google.com, I can see the DNS server go out to its forwarder (128.59.59.70, for example). In this case, I didn't see any packets going out from my DNS server even though bogus. was not in the cache (the debug log was already running and this is the first time I queried this server for bogus. or any TLD). It just returned SERVFAIL without consulting any other DNS server, as in the Microsoft KB article linked above.

  • Virtualhost entries gets over-written when apache httpd.conf is rebuilt

    - by Amitabh
    Background: We have been trying to get a wildcard SSL working on multiple sub domains on a single dedicated address.. We have two sub domains next.my-personal-website.com and blog.my-personal-website.com Part of our strategy has been to edit the httpd.conf and add the NameVirtualHost xx.xx.144.72:443 directive and the virtualhost entries for port 443 for the subdomains there. This works good if we just edit the httpd.conf, add the entries, save it and restart the apache. The problem: But if we add a new sub domain from cpanel or we run the # /usr/local/cpanel/bin/apache_conf_distiller --update # /scripts/rebuildhttpdconf the virtualhost entries that we added manually are no more there in the newly generated httpd.conf file. Only the virtualhost entry for the main domain for port 443 that was there before we made edits to the httpd.conf is there(assuming we are not discussing virtualhost entries for port 80). I understand we need to put the new virtualhost entries in some include files as mentioned here in the cpanel documentation. But am not sure where to. So the question would be where do I put the NameVirtualHost xx.xx.144.72:443 directive and the two virtualhost directive for port 443, so that they are not overwritten when httpd.conf is rebuilt/regenerated later. Virtualhost entries: The two virtualhost entries for the subdomains are: <VirtualHost xx.xx.144.72:443> ServerName next.my-personal-website.com ServerAlias www.next.my-personal-website.com DocumentRoot /home/myguardi/public_html/next.my-personal-website.com ServerAdmin [email protected] UseCanonicalName On CustomLog /usr/local/apache/domlogs/next.my-personal-website.com combined CustomLog /usr/local/apache/domlogs/next.my-personal-website.com-bytes_log "%{%s}t %I .\n%{%s}t %O ." ## User myguardi # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup myguardi myguardi </IfModule> <IfModule !mod_disable_suexec.c> SuexecUserGroup myguardi myguardi </IfModule> ScriptAlias /cgi-bin/ /home/myguardi/public_html/next.my-personal-website.com/cgi-bin/ SSLEngine on SSLCertificateFile /etc/ssl/certs/my-personal-website.com.crt SSLCertificateKeyFile /etc/ssl/private/my-personal-website.com.key SSLCACertificateFile /etc/ssl/certs/my-personal-website.com.cabundle CustomLog /usr/local/apache/domlogs/next.my-personal-website.com-ssl_log combined SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown <Directory "/home/myguardi/public_html/cgi-bin"> SSLOptions +StdEnvVars </Directory> and <VirtualHost xx.xx.144.72:443> ServerName blog.my-personal-website.com ServerAlias www.blog.my-personal-website.com DocumentRoot /home/myguardi/public_html/blog.my-personal-website.com ServerAdmin [email protected] UseCanonicalName On CustomLog /usr/local/apache/domlogs/blog.my-personal-website.com combined CustomLog /usr/local/apache/domlogs/blog.my-personal-website.com-bytes_log "%{%s}t %I .\n%{%s}t %O ." ## User myguardi # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup myguardi myguardi </IfModule> <IfModule !mod_disable_suexec.c> SuexecUserGroup myguardi myguardi </IfModule> ScriptAlias /cgi-bin/ /home/myguardi/public_html/blog.my-personal-website.com/cgi-bin/ SSLEngine on SSLCertificateFile /etc/ssl/certs/my-personal-website.com.crt SSLCertificateKeyFile /etc/ssl/private/my-personal-website.com.key SSLCACertificateFile /etc/ssl/certs/my-personal-website.com.cabundle CustomLog /usr/local/apache/domlogs/blog.my-personal-website.com-ssl_log combined SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown <Directory "/home/myguardi/public_html/cgi-bin"> SSLOptions +StdEnvVars </Directory> and the automatically generated virtualhost entry for the main domain for port 443 is <VirtualHost xx.xx.144.72:443> ServerName my-personal-website.com ServerAlias www.my-personal-website.com DocumentRoot /home/myguardi/public_html ServerAdmin [email protected] UseCanonicalName Off CustomLog /usr/local/apache/domlogs/my-personal-website.com combined CustomLog /usr/local/apache/domlogs/my-personal-website.com-bytes_log "%{%s}t %I .\n%{%s}t %O ." ## User myguardi # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup myguardi myguardi </IfModule> <IfModule !mod_disable_suexec.c> SuexecUserGroup myguardi myguardi </IfModule> ScriptAlias /cgi-bin/ /home/myguardi/public_html/cgi-bin/ SSLEngine on SSLCertificateFile /etc/ssl/certs/my-personal-website.com.crt SSLCertificateKeyFile /etc/ssl/private/my-personal-website.com.key SSLCACertificateFile /etc/ssl/certs/my-personal-website.com.cabundle CustomLog /usr/local/apache/domlogs/my-personal-website.com-ssl_log combined SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown <Directory "/home/myguardi/public_html/cgi-bin"> SSLOptions +StdEnvVars </Directory> # To customize this VirtualHost use an include file at the following location # Include "/usr/local/apache/conf/userdata/ssl/2/myguardi/my-personal-website.com/*.conf" I really appreciate if somebody can tell me how to proceed on this.

  • Reverse lookup SERVFAIL

    - by Quan Tran
    I just set up a DNS server and a web server using Virtualbox. The IP address of the DNS server is 192.168.56.101 and the web server 192.168.56.102. Here are my configuration files for the DNS server: named.conf: // // named.conf // // Provided by Red Hat bind package to configure the ISC BIND named(8) DNS // server as a caching only nameserver (as a localhost DNS resolver only). // // See /usr/share/doc/bind*/sample/ for example named configuration files. // options { directory "/var/named"; dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; memstatistics-file "/var/named/data/named_mem_stats.txt"; //query-source address * port 53; //forward first; forwarders { 8.8.8.8; 8.8.4.4; }; listen-on port 53 { 127.0.0.1; 192.168.56.0/24; }; allow-query { localhost; 192.168.56.0/24; }; recursion yes; dnssec-enable yes; dnssec-validation yes; dnssec-lookaside auto; /* Path to ISC DLV key */ bindkeys-file "/etc/named.iscdlv.key"; managed-keys-directory "/var/named/dynamic"; }; logging { channel default_debug { file "data/named.run"; severity debug 10; print-category yes; print-time yes; print-severity yes; }; }; zone "quantran.com" in { type master; file "named.quantran.com"; }; zone "56.168.192.in-addr.arpa" in { type master; file "named.192.168.56"; allow-update { none; }; }; include "/etc/named.rfc1912.zones"; include "/etc/named.root.key"; named.quantran.com: $TTL 86400 quantran.com.

  • Replies to request coming over a relay goes to relay's internal IP, not to original request's source IP

    - by seaquest
    Dhcpd running on Linux gets a dhcp request over dhcrelay which is running on other remote machine.

However reply does not go to the requesting dhcrelay external IP(192.168.0.81). Instead, it goes to the internal interface IP of machine running dhcrelay.

HOWEVER, I have deleted route on dhcpd server to reach 172.16.17.x subnet. It again tries to send reply to 172.16.17.81. Because it does not know the route it send it from default gateway to the internet. eth0: IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto: UDP (17), length: 328) 192.168.1.2.67 > 172.16.17.81.67: BOOTP/DHCP, Reply, length: 300, hops:1, xid:0x32830125, secs:3, flags: [none] (0x0000) eth0: Your IP: 172.16.17.11 eth0: Gateway IP: 172.16.17.81 eth0: Client Ethernet Address: 00:1e:68:06:eb:37 [|bootp] How can I force dhcpd to force to send replies to requesting IP? Because, it is not much meaningful to add routes to subnet we distribute IP for. Internet - dhcpd - 192.168.0.1 - SOMENET - 192.168.0.81 - dhcrelay - 172.16.17.0/24 192.168.0.1 has no route for 172.16.17.0 and has no interface directly attached to that net.

  • I added some options to stop spam with Postfix, but now won't send email to remote domains

    - by willdanceforfun
    I had a working Postfix server, but added a few lines to my main.cf in a hope to block some common spam. Those lines I added were: smtpd_helo_required = yes smtpd_recipient_restrictions = reject_invalid_hostname, reject_unknown_recipient_domain, reject_unauth_pipelining, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_rbl_client multi.uribl.com, reject_rbl_client dsn.rfc-ignorant.org, reject_rbl_client dul.dnsbl.sorbs.net, reject_rbl_client list.dsbl.org, reject_rbl_client sbl-xbl.spamhaus.org, reject_rbl_client bl.spamcop.net, reject_rbl_client dnsbl.sorbs.net, reject_rbl_client cbl.abuseat.org, reject_rbl_client ix.dnsbl.manitu.net, reject_rbl_client combined.rbl.msrbl.net, reject_rbl_client rabl.nuclearelephant.com, permit It appears my postfix is now receiving normal emails fine, and blocking spam emails. But when I now try to use this server myself to send to a remote domain (an email not on my server) I get bounced, with maillog saying something like this: Nov 12 06:19:36 srv postfix/smtpd[11756]: NOQUEUE: reject: RCPT from unknown[xx.xx.x.xxx]: 450 4.1.2 <[email protected]>: Recipient address rejected: Domain not found; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<[192.168.1.100]> Is that saying 'domain not found' for gmail.com?

  • Unable to list contents/remove directory (linux ext3)

    - by RedKrieg
    System is CentOS5 x86_64, completely up to date. I've got a folder that can't be listed (ls just hangs, eating memory until it is killed). The directory size is nearly 500k: root@server [/home/user/public_html/domain.com/wp-content/uploads/2010/03]# stat . File: `.' Size: 458752 Blocks: 904 IO Block: 4096 directory Device: 812h/2066d Inode: 44499071 Links: 2 Access: (0755/drwxr-xr-x) Uid: ( 3292/ user) Gid: ( 3287/ user) Access: 2012-06-29 17:31:47.000000000 -0400 Modify: 2012-10-23 14:41:58.000000000 -0400 Change: 2012-10-23 14:41:58.000000000 -0400 I can see the file names if I use ls -1f, but it just repeats the same 48 files ad infinitum, all of which have non-ascii characters somewhere in the file name: La-critic\363-al-servicio-la-privacidad-300x160.jpg When I try to access the files (say to copy them or remove them) I get messages like the following: lstat("/home/user/public_html/domain.com/wp-content/uploads/2010/03/Sebast\355an-Pi\361era-el-balc\363n-150x120.jpg", 0x7fff364c52c0) = -1 ENOENT (No such file or directory) I tried altering the code found on this man page and modified the code to call unlink for each file. I get the same ENOENT error from the unlink call: unlink("/home/user/public_html/domain.com/wp-content/uploads/2010/03/Marca-naci\363n-Madrid-150x120.jpg") = -1 ENOENT (No such file or directory) I also straced a "touch", grabbed the syscalls it makes and replicated them, then tried to unlink the resulting file by name. This works fine, but the folder still contains an entry by the same name after the operation completes and the program runs for an arbitrarily long time (strace output ended up at 20GB after 5 minutes and I stopped the process). I'm stumped on this one, I'd really prefer not to have to take this production machine (hundreds of customers) offline to fsck the filesystem, but I'm leaning toward that being the only option at this point. If anyone's had success using other methods for removing files (by inode number, I can get those with the getdents code) I'd love to hear them. (Yes, I've tried find . -inum <inode> -exec rm -fv {} \; and it still has the problem with unlink returning ENOENT) For those interested, here's the diff between that man page's code and mine. I didn't bother with error checking on mallocs, etc because I'm lazy and this is a one-off: root@server [~]# diff -u listdir-orig.c listdir.c --- listdir-orig.c 2012-10-23 15:10:02.000000000 -0400 +++ listdir.c 2012-10-23 14:59:47.000000000 -0400 @@ -6,6 +6,7 @@ #include <stdlib.h> #include <sys/stat.h> #include <sys/syscall.h> +#include <string.h> #define handle_error(msg) \ do { perror(msg); exit(EXIT_FAILURE); } while (0) @@ -17,7 +18,7 @@ char d_name[]; }; -#define BUF_SIZE 1024 +#define BUF_SIZE 1024*1024*5 int main(int argc, char *argv[]) { @@ -26,11 +27,16 @@ struct linux_dirent *d; int bpos; char d_type; + int deleted; + int file_descriptor; fd = open(argc > 1 ? argv[1] : ".", O_RDONLY | O_DIRECTORY); if (fd == -1) handle_error("open"); + char* full_path; + char* fd_path; + for ( ; ; ) { nread = syscall(SYS_getdents, fd, buf, BUF_SIZE); if (nread == -1) @@ -55,7 +61,24 @@ printf("%4d %10lld %s\n", d->d_reclen, (long long) d->d_off, (char *) d->d_name); bpos += d->d_reclen; + if ( d_type == DT_REG ) + { + full_path = malloc(strlen((char *) d->d_name) + strlen(argv[1]) + 2); //One for the /, one for the \0 + strcpy(full_path, argv[1]); + strcat(full_path, (char *) d->d_name); + + //We're going to try to "touch" the file. + //file_descriptor = open(full_path, O_WRONLY|O_CREAT|O_NOCTTY|O_NONBLOCK, 0666); + //fd_path = malloc(32); //Lazy, only really needs 16 + //sprintf(fd_path, "/proc/self/fd/%d", file_descriptor); + //utimes(fd_path, NULL); + //close(file_descriptor); + deleted = unlink(full_path); + if ( deleted == -1 ) printf("Error unlinking file\n"); + break; //Break on first try + } } + break; //Break on first try } exit(EXIT_SUCCESS);

  • Perl Scripts Seem to be Caching?

    - by Ben Liyanage
    I'm running a perl script via mod_perl with Apache. I am trying to parse parameters in a restful fashion (aka GET www.domain.com/rest.pl/Object/ID). If I specify the ID like this: GET www.domain.com/rest.pl/Object/1234 I will get object 1234 back as a result as expected. However, if I specify an incorrect hacked url like this GET www.domain.com/rest.pl/Object/123 I will also get back object 1234. I am pretty sure that the issue in this question is happening so I packaged up my method and invoked it from my core script out of the package. Even after that I am still seeing the threads returning seemingly cached data. One of the recommendations in the aforementioned article is to replace my with our. My impression from reading up on our vs my was that our is global and my is local. My assumption is the the local variable gets reinitialized each time. That said, like in my code example below I am resetting the variables each time with new values. Apache Perl Configuration is set up like this: PerlModule ModPerl::Registry <Directory /var/www/html/perl/> SetHandler perl-script PerlHandler ModPerl::Registry Options +ExecCGI </Directory> Here is the perl script getting invoked directly: #!/usr/bin/perl -w use strict; use warnings; use Rest; Rest::init(); Here is my package Rest. This file contains various functions for handling the rest requests. #!/usr/bin/perl -w package Rest; use strict; # Other useful packages declared here. our @EXPORT = qw( init ); our $q = CGI->new; sub GET($$) { my ($path, $code) = @_; return unless $q->request_method eq 'GET' or $q->request_method eq 'HEAD'; return unless $q->path_info =~ $path; $code->(); exit; } sub init() { eval { GET qr{^/ZonesByCustomer/(.+)$} => sub { Rest::Zone->ZonesByCustomer($1); } } } # packages must return 1 1; As a side note, I don't completely understand how this eval statement works, or what string is getting parsed by the qr command. This script was largely taken from this example for setting up a rest based web service with perl. I suspect it is getting pulled from that magical $_ variable, but I'm not sure if it is, or what it is getting populated with (clearly the query string or url, but it only seems to be part of it?). Here is my package Rest::Zone, which will contain the meat of the functional actions. I'm leaving out the specifics of how I'm manipulating the data because it is working and leaving this as an abstract stub. #!/usr/bin/perl -w package Rest::Zone; sub ZonesByCustomer($) { my ($className, $ObjectID) = @_; my $q = CGI->new; print $q->header(-status=>200, -type=>'text/xml',expires => 'now', -Cache_control => 'no-cache', -Pragma => 'no-cache'); my $objectXML = "<xml><object>" . $ObjectID . "</object></xml>"; print $objectXML; } # packages must return 1 1; What is going on here? Why do I keep getting stale or cached values?

  • How to read registry correctly for multiple values in c?

    - by kampi
    Hi! I created a .dll which should work like the RunAs command. The only difference is, that it should read from registry. My problem is, that i need to reed 3 values from the registry, but i can't. It reads the first, than it fails at the second one (Password) with error code 2, which means "The system cannot find the file specified". If i query only for domain and username then it is ok, if i query only for password then it it still succeeds, but if i want to query all three then it fails. Can someone tell me, what i am doing wrong? Heres my code: HKEY hKey = 0; DWORD dwType = REG_SZ; DWORD dwBufSize = sizeof(buf); TCHAR szMsg [MAX_PATH + 32]; HANDLE handle; LPVOID lpMsgBuf; if( RegOpenKeyEx( HKEY_CURRENT_USER, TEXT("SOFTWARE\\Kampi Corporation\\RunAs!"), 0, KEY_QUERY_VALUE, &hKey ) == ERROR_SUCCESS ) { if( RegQueryValueEx( hKey, TEXT("Username"), 0, &dwType, (LPBYTE)buf, &dwBufSize ) == ERROR_SUCCESS ) { memset( szMsg, 0, sizeof( szMsg ) ); wsprintf ( szMsg, _T("%s"), buf ); mbstowcs( wuser, szMsg, 255 ); RegCloseKey( hKey ); } else { MessageBox ( pCmdInfo->hwnd, "Can not query for Username key value!", _T("RunAs!"), MB_ICONERROR ); RegCloseKey( hKey ); return -1; } } else { CSimpleShlExt::showerror( GetLastError(), pCmdInfo->hwnd, "RegOpenKeyEx failed for Username with error code :: " ); return -1; } if( RegOpenKeyEx( HKEY_CURRENT_USER, TEXT("SOFTWARE\\Kampi Corporation\\RunAs!"), 0, KEY_QUERY_VALUE ,&hKey ) == ERROR_SUCCESS ) { if( RegQueryValueEx( hKey, TEXT("Password"), 0, &dwType, (LPBYTE)buf, &dwBufSize ) == ERROR_SUCCESS ) { memset( szMsg, 0, sizeof( szMsg ) ); wsprintf ( szMsg, _T("%s"), buf ); mbstowcs( wpass, szMsg, 255 ); RegCloseKey( hKey ); } else { char test[200]; sprintf(test,"Can not query for Password key value!

  • Saving images only available when logged in

    - by James
    Hi, I've been having some trouble getting images to download when logged into a website that requires you to be logged in. The images can only be viewed when you are logged in to the site, but you cannot seem to view them directly in the browser if you copy its location into a tab/new window (it redirects to an error page - so I guess the containing folder has be .htaccess-ed). Anyway, the code I have below allows me to log in and grab the HTML content, which works well - but I cannot grab the images ... this is where I need help! <? // curl.php class Curl { public $cookieJar = ""; public function __construct($cookieJarFile = 'cookies.txt') { $this->cookieJar = $cookieJarFile; } function setup() { $header = array(); $header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,"; $header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/gif;q=0.8,image/x-bitmap;q=0.8,image/jpeg;q=0.8,image/png,*/*;q=0.5"; $header[] = "Cache-Control: max-age=0"; $header[] = "Connection: keep-alive"; $header[] = "Keep-Alive: 300"; $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7"; $header[] = "Accept-Language: en-us,en;q=0.5"; $header[] = "Pragma: "; // browsers keep this blank. curl_setopt($this->curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7'); curl_setopt($this->curl, CURLOPT_HTTPHEADER, $header); curl_setopt($this->curl, CURLOPT_COOKIEJAR, $this->cookieJar); curl_setopt($this->curl, CURLOPT_COOKIEFILE, $this->cookieJar); curl_setopt($this->curl, CURLOPT_AUTOREFERER, true); curl_setopt($this->curl, CURLOPT_FOLLOWLOCATION, true); curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, true); } function get($url) { $this->curl = curl_init($url); $this->setup(); return $this->request(); } function getAll($reg, $str) { preg_match_all($reg, $str, $matches); return $matches[1]; } function postForm($url, $fields, $referer = '') { $this->curl = curl_init($url); $this->setup(); curl_setopt($this->curl, CURLOPT_URL, $url); curl_setopt($this->curl, CURLOPT_POST, 1); curl_setopt($this->curl, CURLOPT_REFERER, $referer); curl_setopt($this->curl, CURLOPT_POSTFIELDS, $fields); return $this->request(); } function getInfo($info) { $info = ($info == 'lasturl') ? curl_getinfo($this->curl, CURLINFO_EFFECTIVE_URL) : curl_getinfo($this->curl, $info); return $info; } function request() { return curl_exec($this->curl); } } ?> And below is the page that uses it. <? // data.php include('curl.php'); $curl = new Curl(); $url = "http://domain.com/login.php"; $newURL = "http://domain.com/go_here.php"; $username = "user"; $password = "pass"; $fields = "user=$username&pass=$password"; // Calling URL $referer = "http://domain.com/refering_page.php"; $html = $curl->postForm($url, $fields, $referer); $html = $curl->get($newURL); echo $html; ?> I've tried putting the direct URL for the image into $newURL but that doesn't get the image - it simply returns an error saying since that folder is not available to view directly. I've tried varying the above in different ways, but I haven't been successful in getting an image, though I have managed to get a screen through basically saying error 405 and/or 406 (but not the image I want). Any help would be great!

  • jQuery AJAX (google PageRank)

    - by RobertPitt
    Hey guys, I need a little help.. iv'e been developing a Jqery plug-in to get the page ranks of urls on a website using XHR, The problem is when requesting the rank from google servers the page is returned no content, but if i use an inspector and get the url that was requests and go to it via my browser the pageranks are shown. so it must be something with headers but its just got me puzzled. Heres some source code but i have removed several aspects that are not needed to review. pagerank.plugin.js ( $.fn.PageRank = function(callback) { var _library = new Object(); //Creat the system library _library.parseUrl = function(a) { var b = {}; var a = a || ''; /* * parse the url to extract its parts */ if (a = a.match(/((s?ftp|https?):\/\/){1}([^\/:]+)?(:([0-9]+))?([^\?#]+)?(\?([^#]+))?(#(.+))?/)) { b.scheme = a[2] ? a[2] : "http"; b.host = a[3] ? a[3] : null; b.port = a[5] ? a[5] : null; b.path = a[6] ? a[6] : null; b.args = a[8] ? a[8] : null; b.anchor = a[10] ? a[10] : null } return b } _library.ValidUrl = function(url) { var b = true; return b = url.host === undefined ? false : url.scheme != "http" && url.scheme != "https" ? false : url.host == "localhost" ? false : true } _library.toHex = function(a){ return (a < 16 ?

  • Asp.net mvc application deployment / security issues

    - by WestDiscGolf
    I'll start with appologies; I wasn't sure if this was best posted here of Server Fault so if its in the wrong place then please move :-) Basic information I have written the first module of a new application at work. This is written using Visual Studio 2010, targetting .net 3.5 (at the moment) and asp.net mvc 2. This has been working fine during development running on the built in Development server from VS but however does not work once deployed to IIS 7/7.5. To deploy the application, I have built it in release mode and created a deployment package by right clicking on the project in the solution explorer (this will be done with an automated build in tfs once upgrade from the beta). This has then been imported into IIS on the server. The application is using windows/domain authentication. Issue #1 I can fire up internet explorer and browse to the application from a client computer as well as on a remote desktop connection. I can execute the code which reads/stores data in Session fine from the IE instance on the remote desktop but if I browse to it from the client pc it seems to lose the session state. I click on the form submit and the page refreshes and doesn't execute the required code. I've tried setting with; InProc, SQLServer and StateServer. but with no luck :-( Issue #2 As part of the application it views PDF and Tiff documents on the fly which are on a network share on the office network and creates thumbnails if the document hasn't been viewed before. This works if running on the machine the application is deployed to; however when browsing from a client pc I get an error saying: Access to the path '\\fileserver\folder\file.tif' is denied Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.UnauthorizedAccessException: Access to the path '\\fileserver\folder\file.TIF' is denied. ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. As this is on a different server the user is not accessible. To get round this I have tried: 1 - setting the application pool to run as domain administrator (I know this is a security risk, but I'm just trying to get it to work at the moment!) 2 - to set the log on account for World Wide Web Publishing service to be the domain admin . When trying to restart the service I get ... Windows could not start the World Wide Web Publishing Service service on the Local Computer. Error 1079: The account specified for this service is different from the account specified fro the other services running in the same process. Any pointers/help would be much appriciated as I'm pulling my hair out (of what little I have left). Update I've been using this funky little tool I found - DelegConfig v2 beta (Delegation / Kerberos Configuration Tool). This has been really usefull. So I've got the accessing of the file share working (there is a test page which will read the files) so now I've just got the issue of passing through the users credentials through to the SQL Server (wans't my choice to do it this way!!) to execute the queries etc. but I can't get it to log on as the user. It tries to access it as "NT Authority\Network Service" which doesn't have a sql login (as should be the logged on user). My connection string is: <add name="User" connectionString="Data Source=.;Integrated Security=True" providerName="System.Data.SqlClient" /> No initial catalog is specified as the system is over multiple dbs (also wasn't my choice!!). I really appriciate all the help so far! :-) Any further hints?!
