  • Transparent Squid : Logging client ip problem

    - by llazzaro
    Hello, I am using the following rules in iptables in my network to use a transparent proxy * iptables -t nat -A PREROUTING -i eth0 -s ! squid-box -p tcp --dport 80 -j DNAT --to squid-box:3128 * iptables -t nat -A POSTROUTING -o eth0 -s local-network -d squid-box -j SNAT --to iptables-box * iptables -A FORWARD -s local-network -d squid-box -i eth0 -o eth0 -p tcp --dport 3128 -j ACCEPT But my squid log, always logs gateway IP (172.16.0.1) Do you know an alternative to not lose client IP? (of course avoid saing manual proxy setup!)

  • Getting Dynamic in SSIS Queries

    - by ejohnson2010
    When you start working with SQL Server and SSIS, it isn’t long before you find yourself wishing you could change bits of SQL queries dynamically. Most commonly, I see people that want to change the date portion of a query so that you can limit your query to the last 30 days, for example. This can be done using a combination of expressions and variables. I will do this in two parts, first I will build a variable that will always contain the 1 st day of the previous month and then I will dynamically...(read more)

  • Possible to direct naked domain to external IP

    - by Luke
    So I found this post: configure Bind to have a custom domain on tumblr and I was trying to ask a related question: Would it be possible to set up an A record pointing traffic to domain.com to Tumblr and feed.domain.com to the IP address of my choice? In other words, by setting up a naked domain A record to Tumblr's IP, will I inherently lose traffic to feed.domain.com? Can I write another A record for the specific subdomains I want to point to my server? I hope this makes sense.

  • A Custom View Engine with Dynamic View Location

    - by imran_ku07
        Introduction:          One of the nice feature of ASP.NET MVC framework is its pluggability. This means you can completely replace the default view engine(s) with a custom one. One of the reason for using a custom view engine is to change the default views location and sometimes you need to change the views location at run-time. For doing this, you can extend the default view engine(s) and then change the default views location variables at run-time.  But, you cannot directly change the default views location variables at run-time because they are static and shared among all requests. In this article, I will show you how you can dynamically change the views location without changing the default views location variables at run-time.       Description:           Let's say you need to synchronize the views location with controller name and controller namespace. So, instead of searching to the default views location(Views/ControllerName/ViewName) to locate views, this(these) custom view engine(s) will search in the Views/ControllerNameSpace/ControllerName/ViewName folder to locate views.           First of all create a sample ASP.NET MVC 3 application and then add these custom view engines to your application,   public class MyRazorViewEngine : RazorViewEngine { public MyRazorViewEngine() : base() { AreaViewLocationFormats = new[] { "~/Areas/{2}/Views/%1/{1}/{0}.cshtml", "~/Areas/{2}/Views/%1/{1}/{0}.vbhtml", "~/Areas/{2}/Views/%1/Shared/{0}.cshtml", "~/Areas/{2}/Views/%1/Shared/{0}.vbhtml" }; AreaMasterLocationFormats = new[] { "~/Areas/{2}/Views/%1/{1}/{0}.cshtml", "~/Areas/{2}/Views/%1/{1}/{0}.vbhtml", "~/Areas/{2}/Views/%1/Shared/{0}.cshtml", "~/Areas/{2}/Views/%1/Shared/{0}.vbhtml" }; AreaPartialViewLocationFormats = new[] { "~/Areas/{2}/Views/%1/{1}/{0}.cshtml", "~/Areas/{2}/Views/%1/{1}/{0}.vbhtml", "~/Areas/{2}/Views/%1/Shared/{0}.cshtml", "~/Areas/{2}/Views/%1/Shared/{0}.vbhtml" }; ViewLocationFormats = new[] { "~/Views/%1/{1}/{0}.cshtml", "~/Views/%1/{1}/{0}.vbhtml", "~/Views/%1/Shared/{0}.cshtml", "~/Views/%1/Shared/{0}.vbhtml" }; MasterLocationFormats = new[] { "~/Views/%1/{1}/{0}.cshtml", "~/Views/%1/{1}/{0}.vbhtml", "~/Views/%1/Shared/{0}.cshtml", "~/Views/%1/Shared/{0}.vbhtml" }; PartialViewLocationFormats = new[] { "~/Views/%1/{1}/{0}.cshtml", "~/Views/%1/{1}/{0}.vbhtml", "~/Views/%1/Shared/{0}.cshtml", "~/Views/%1/Shared/{0}.vbhtml" }; } protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath) { var nameSpace = controllerContext.Controller.GetType().Namespace; return base.CreatePartialView(controllerContext, partialPath.Replace("%1", nameSpace)); } protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath) { var nameSpace = controllerContext.Controller.GetType().Namespace; return base.CreateView(controllerContext, viewPath.Replace("%1", nameSpace), masterPath.Replace("%1", nameSpace)); } protected override bool FileExists(ControllerContext controllerContext, string virtualPath) { var nameSpace = controllerContext.Controller.GetType().Namespace; return base.FileExists(controllerContext, virtualPath.Replace("%1", nameSpace)); } } public class MyWebFormViewEngine : WebFormViewEngine { public MyWebFormViewEngine() : base() { MasterLocationFormats = new[] { "~/Views/%1/{1}/{0}.master", "~/Views/%1/Shared/{0}.master" }; AreaMasterLocationFormats = new[] { "~/Areas/{2}/Views/%1/{1}/{0}.master", "~/Areas/{2}/Views/%1/Shared/{0}.master", }; ViewLocationFormats = new[] { "~/Views/%1/{1}/{0}.aspx", "~/Views/%1/{1}/{0}.ascx", "~/Views/%1/Shared/{0}.aspx", "~/Views/%1/Shared/{0}.ascx" }; AreaViewLocationFormats = new[] { "~/Areas/{2}/Views/%1/{1}/{0}.aspx", "~/Areas/{2}/Views/%1/{1}/{0}.ascx", "~/Areas/{2}/Views/%1/Shared/{0}.aspx", "~/Areas/{2}/Views/%1/Shared/{0}.ascx", }; PartialViewLocationFormats = ViewLocationFormats; AreaPartialViewLocationFormats = AreaViewLocationFormats; } protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath) { var nameSpace = controllerContext.Controller.GetType().Namespace; return base.CreatePartialView(controllerContext, partialPath.Replace("%1", nameSpace)); } protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath) { var nameSpace = controllerContext.Controller.GetType().Namespace; return base.CreateView(controllerContext, viewPath.Replace("%1", nameSpace), masterPath.Replace("%1", nameSpace)); } protected override bool FileExists(ControllerContext controllerContext, string virtualPath) { var nameSpace = controllerContext.Controller.GetType().Namespace; return base.FileExists(controllerContext, virtualPath.Replace("%1", nameSpace)); } }             Here, I am extending the RazorViewEngine and WebFormViewEngine class and then appending /%1 in each views location variable, so that we can replace /%1 at run-time. I am also overriding the FileExists, CreateView and CreatePartialView methods. In each of these method implementation, I am replacing /%1 with controller namespace. Now, just register these view engines in Application_Start method in Global.asax.cs file,   protected void Application_Start() { ViewEngines.Engines.Clear(); ViewEngines.Engines.Add(new MyRazorViewEngine()); ViewEngines.Engines.Add(new MyWebFormViewEngine()); ................................................ ................................................ }             Now just create a controller and put this controller's view inside Views/ControllerNameSpace/ControllerName folder and then run this application. You will find that everything works just fine.       Summary:          ASP.NET MVC uses convention over configuration to locate views. For many applications this convention to locate views is acceptable. But sometimes you may need to locate views at run-time. In this article, I showed you how you can dynamically locate your views by using a custom view engine. I am also attaching a sample application. Hopefully you will enjoy this article too.

  • Dynamic IP and spam filtering

    - by pipalia
    Is it possible to filter incoming spam when the mail server is hosted on a dynamic IP. Static IP is not an option at the moment. Outgoing mail is relayed through a third party service which works great, but I am not sure how I could filter incoming mail within Domino. Has anyone figured out how to do achieve this? Or I am limited to what Domino has to offer to control spam and doing it manually by creating mail rules?

  • SEO optimization for AJAX site and dynamic HTML canvas

    - by Christian Benincasa
    I have a site that uses AJAX to query the Last.fm database and then dynamically draws a graph of the results on an HTML canvas. In the search function, I have a command that sets window.location.hash to the search parameters. I also have a function that checks if a hash was provided in the url and if so, generates the page. For example, http://www.thenlistento.com/#!/led+zeppelin will automatically navigate to a search page for Led Zeppelin. My question is, how do optimize this set up for SEO? Can it be done at all? I've taken a look at Google Webmaster Docs and read over the hashbang protocol, but I'm not totally sure how to apply it to my situation..or even if I can at all. Any help/suggestions would be greatly appreciated. Link to the site: http://www.thenlistento.com

  • Dynamic real-time pathfinding with C# and unity

    - by Yakri
    A buddy and I are working on a simple 2D top down arena combat game similar to OpenGLAD (grew up on ye olde GLADIATOR). Thing is, we want to make some substantial deviation from our source of inspiration, including completely destructible/changeable terrain. Like rivers that can be frozen, walls which can be knocked down, etc. As well as letting players and NPC's build new terrain objects, some of which cannot be moved through or seen through. So I'm tasked with creating the AI, starting with pathfinding. Because of all the changeable terrain, we need something that can check to see if the player/other NPC's are in line of sight, and which can then check to find current paths around existing terrain, without getting completely confused by new terrain popping up, and old terrain vanishing, and even capable of breaking through terrain. A lot of that will just be filling in the framework of the feature, but I really just don't know where to start. What I'm really looking for are relevant websites, books, articles, or keywords to google. I just can't quite find a direction to start in, because most pathfinding types we've googled up just won't give us even the most basic level of robustness we need.

  • Dynamic Tab Implementation in ADF

    - by Vijay Mohan
    Well, this can be a common usecase across apps to open tabs dynamically at runtime based on the request.Well, in order to achieve this you can have a parent container, lets say a panelTab component.Inside panelTab , u can have a showDetailItem inside an af:foreach or an af:iterator binded to a bean static list which will have as many show detail items as you wish to be shown.something like this.private static List = { new showDetailItem("1"),new ShowDetailItem("2") ...};now in the backing bean you can have a method that takes care of rendering and disclosing an specific tab based on the index.public void openMyTab(){List<MyItems> list = refToParentContainer.getChildren();int indexOfTabToBeOpened = //Write a method that will compute the tab index of the next //tab.list.get(index).setRendered(true);list.get(index).setDisclosed(true);similarly you can set other properties too.}Else, instead of having af:foreach/iterator iterating through the SD items , you can go for static SDs in the page with render property set to false and then you can follow the same approach to render/disclose it at runtime.

  • Connecting to localhost resolves 127.0.0.1 but connects with external IP [Linux, Debian]

    - by skgsergio
    I'm having a problem with a dedicated server, I don't known if it's the default behavior but this is the problem: If I connect to a service located on the server with localhost the service gets as source IP the external IP. Let me show an example, I use netcat for listening on 127.0.0.1:4444 xxxxxx # nc -vv -l -s 127.0.0.1 -p 4444 listening on [127.0.0.1] 4444 ... Lets check if it's ok: xxxxxx ~ # netstat -atnp | grep 4444 tcp 0 0 127.0.0.1:4444 0.0.0.0:* LISTEN 14038/nc Ok lets connect: xxxxxx ~ # nc -vv 127.0.0.1 4444 localhost [127.0.0.1] 4444 (?) open Return to the tty that have the listening process and I get this: connect to [127.0.0.1] from xxxxxx.net [176.31.xxx.xx] 50354 So that's the problem. I have a server daemon that have to listen on localhost and checks that the ip is 127.0.0.1 when the client connects but for some reason when I connect to localhost it reports the external ip... If I do the same with IPv6 it works as excepted... Detects connection as localhost (::1). Some info that can be useful: "localhost" resolves without problems to 127.0.0.1 xxxxxx ~ # ping -c1 localhost PING localhost (127.0.0.1) 56(84) bytes of data. 64 bytes from localhost (127.0.0.1): icmp_req=1 ttl=64 time=0.086 ms Nothing weird on my hosts file, I think... xxxxxx ~ # grep -v ^# /etc/hosts 127.0.0.1 localhost localhost.localdomain 176.31.xxx.xx xxxxxx.net ns1.xxxxxx.net ::1 ip6-localhost ip6-loopback feo0::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts And ifconfig reports all ok... eth0 Link encap:Ethernet HWaddr e0:69:95:d8:30:a1 inet addr:176.31.xxx.xx Bcast:176.31.108.255 Mask:255.255.255.0 inet6 addr: 2001:41d0:8:xxxx::/64 Scope:Global inet6 addr: 2001:41d0:8:xxxx:x:xx:xx:xx/64 Scope:Global inet6 addr: fe80::e269:95ff:fed8:30a1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:16916 errors:0 dropped:0 overruns:0 frame:0 TX packets:16914 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:8410679 (8.0 MiB) TX bytes:10539881 (10.0 MiB) Interrupt:28 Base address:0xe000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:5570 errors:0 dropped:0 overruns:0 frame:0 TX packets:5570 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:744490 (727.0 KiB) TX bytes:744490 (727.0 KiB)

  • Highly scalable and dynamic "rule-based" applications?

    - by Prof Plum
    For a large enterprise app, everyone knows that being able to adjust to change is one of the most important aspects of design. I use a rule-based approach a lot of the time to deal with changing business logic, with each rule being stored in a DB. This allows for easy changes to be made without diving into nasty details. Now since C# cannot Eval("foo(bar);") this is accomplished by using formatted strings stored in rows that are then processed in JavaScript at runtime. This works fine, however, it is less than elegant, and would not be the most enjoyable for anyone else to pick up on once it becomes legacy. Is there a more elegant solution to this? When you get into thousands of rules that change fairly frequently it becomes a real bear, but this cannot be that uncommon of a problem that someone has not thought of a better way to do this. Any suggestions? Is this current method defensible? What are the alternatives? Edit: Just to clarify, this is a large enterprise app, so no matter which solution works, there will be plenty of people constantly maintaining its rules and data (around 10). Also, The data changes frequently enough to say that some sort of centralized server system is basically a must.

  • Coding Dynamic Events?

    - by Joey Green
    I have no idea what the title of this question should be so bare with me. My game has turns. On a turn a player does something and this can result in a random number of explosions that occur at different times. I know when the explosions are done. I need to know when ALL are done and then do some other action. Also, each explosion is the same amount of time, say 3 seconds.. Right now I'm thinking of using a counter to hold how many explosions are happening. Then once the explosion is finished decrement this counter. Once the counter is zero, do my action. This idea is inspired by objective-c memory management btw. Anyways, does this sound like a good approach or would there be another way. An alternative might be to figure out the explosion who happened last and let it be responsible for calling this subsequent action. I'm asking mostly, because I haven't done this before and am trying to figure out if there are bugs that may occur that I'm not foreseeing.

  • Adding Vertices to a dynamic mesh via Method Call

    - by Raven Dreamer
    I have a C# Struct with a static method, "Get Shape" which populates a List with the vertices of a polyhedron. Method Signature: public static void GetShape(Block b, int x, int y, int z, List<Vector3> vertices, List<int> triangles, List<Vector2> uvs, List<Vector2> uv2s) Adding directly to the vertices list (via vertices.Add(vector3) ), the code works as expected, and the new polyhedron appears when I trigger the method. However, I want to do some processing on the vertices I'm adding (a rotation), and the most sensible way I can think to do that is by creating a separate list of Vector3s, and then combining the lists when I'm done. However, vertices.AddRange(newVerts) does not add the shape to the mesh, nor does a foreach loop with verts.Add(vertices[i]). And this is before I've added in any of the processing! I have a feeling this might stem from passing the list of vertices in as a parameter, rather than returning a list and then adding to the vertices in the calling object, but since I'm filling 4 lists, I was trying to avoid having to create a data struct to return all four at once. Any ideas? The working version of the method is reprinted below, in full: public static void GetShape(Block b, int x, int y, int z, List<Vector3> vertices, List<int> triangles, List<Vector2> uvs, List<Vector2> uv2s) { //List<Vector3> vertices = new List<Vector3>(); int l_blockShape = b.blockShape; int l_blockType = b.blockType; //CheckFace checks if the block is empty //if this block is empty, don't draw anything. int vertexIndex; //only y faces need to be hidden. //if((l_blockShape & BlockShape.NegZFace) == BlockShape.NegZFace) { vertexIndex = vertices.Count; //top left, top right, bottom right, bottom left vertices.Add(new Vector3(x+.2f, y + 1, z+.2f)); vertices.Add(new Vector3(x+.8f, y + 1, z+.2f)); vertices.Add(new Vector3(x+.8f, y , z+.2f)); vertices.Add(new Vector3(x+.2f, y , z+.2f));

  • Is dynamic casting Entities A good design?

    - by Milo
    For my game, Everything inherits from Entity, then other things like Player, PhysicsObject, etc, inherit from Entity. The physics engine sends collision callbacks which has an Entity* to the B that A collided on. Then, lets say A is a Bullet, A tries to cast the entity as a player, if it succeeds, it reduces the player's health. Is this a good design? The problem I have with a message system is that I'd need messages for everything, like: entity.sendMessage(SET_PLAYER_HEALTH,16); So that's why I think casting is cleaner.

  • Multi-level wildcard (catch-all) DNS setup *.*.domain.com => one IP/CNAME

    - by Jan Rovner
    It is well known that it is possible to configure a DNS server to do a "catch-all" resolving on a single subdomain level, such as *.example.com. IN A x.x.x.x, so that anything.example.com maps to a single IP/CNAME. However, I need to set up an at least "level-2" wildcard sub-subdomain catch-all wildcard system so that any.thing.example.com or better, item.of.any.level.under.example.com will be resolved to a single IP. Has anyone got this working?

  • Remove IP address from the URL of website using apache

    - by sapatos
    I'm on an EC2 instance and have a domain domain.com linked to the EC2 nameservers and it happily is serving my pages if I type domain.com in the URL. However when the page is served it resolves the url to: 1.1.1.10/directory/page.php. Using apache I've set up the following VirtualHost, following examples provided at http://httpd.apache.org/docs/2.0/dns-caveats.html Listen 80 NameVirtualHost 1.1.1.10:80 <VirtualHost 1.1.1.10:80> DocumentRoot /var/www/html/directory ServerName domain.com # Other directives here ... <FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$"> Header set Cache-Control "max-age=290304000, public" </FilesMatch> </VirtualHost> However I'm not getting any changes to how the URL is displayed. This is the only VirtualHost configured on this site and I've confirmed its the one being used as I've managed to break it a number of times whilst experimenting with the configuration.

    I use PeerBlock (former PeerGuardian) and, as a consequence, Yahoo Messenger (actually Pidgin) fails to connect every once in a while; PeerBlock reports the access being blocked because the destination IP is in one of the block lists. Where can I get a list of all IP ranges belonging to Yahoo Messenger so I can configure an "allow" rule in PeerBlock?

  • Dynamic/Adaptive RLE

    - by Lucius
    So, I'm developing a 2D, tile based game and a map maker thingy - all in Java. The problem is that recently I've been having some memory issues when about 4 maps are loaded. Each one of these maps are composed of 128x128 tiles and have 4 layers (for details and stuff). I already spent a good amount of time searching for solutions and the best thing I found was run-length enconding (RLE). It seems easy enough to use with static data, but is there a way to use it with data that is constantly changing, without a big drop in performance? In my maps, supposing I'm compressing the columns, I would have 128 rows, each with some amount of data (hopefully less than it would be without RLE). Whenever I change a tile, that whole row would have to be checked and I'm affraid that would slow down too much the production (and I'm in a somewhat tight schedule). Well, worst case scenario I work on each map individually, and save them using RLE, but it would be really nice if I could avoind that. EDIT: What I'm currently using to store the data for the tiles is a 2D array of HashMaps that use the layer as key and store the id of the tile in that position - like this: private HashMap< Integer, Integer [][]

  • How to setup multiple Apache SSL sites using multiple IP addresses

    - by Jeff
    How do you setup a single Apache2 config to host multiple HTTPS sites each on their own IP address? There will also be multiple HTTP sites on just a single IP address. I do not want to use Server Name Indication (SNI) as described here, and I'm only concerned with the important top-level Apache directives. That is, I just need to know the skeleton of how my config should look. The basic setup looks like this: Hosted on 1.1.1.1:80 (HTTP) - example.com - example.net - example.org Hosted on 2.2.2.2:443 (HTTPS) - secure.com Hosted on 3.3.3.3:443 (HTTPS) - secure.net Hosted on 4.4.4.4:443 (HTTPS) - secure.org And here are the important config directives I have so far, which is the closest I've come to a working iteration, but still no dice. I know I'm close, just need a little push in the right direction. Listen 1.1.1.1:80 Listen 2.2.2.2:443 Listen 3.3.3.3:443 Listen 4.4.4.4:443 NameVirtualHost 1.1.1.1:80 NameVirtualHost 2.2.2.2:443 NameVirtualHost 3.3.3.3:443 NameVirtualHost 4.4.4.4:443 # HTTP VIRTUAL HOSTS: <VirtualHost 1.1.1.1:80> ServerName example.com DocumentRoot /home/foo/example.com </VirtualHost> <VirtualHost 1.1.1.1:80> ServerName example.net DocumentRoot /home/foo/example.net </VirtualHost> <VirtualHost 1.1.1.1:80> ServerName example.org DocumentRoot /home/foo/example.org </VirtualHost> # HTTPS VIRTUAL HOSTS: <VirtualHost 2.2.2.2:443> ServerName secure.com DocumentRoot /home/foo/secure.com SSLEngine on SSLCertificateFile /home/foo/ssl/secure.com.crt SSLCertificateKeyFile /home/foo/ssl/secure.com.key SSLCACertificateFile /home/foo/ssl/ca.txt </VirtualHost> <VirtualHost 3.3.3.3:443> ServerName secure.net DocumentRoot /home/foo/secure.net SSLEngine on SSLCertificateFile /home/foo/ssl/secure.net.crt SSLCertificateKeyFile /home/foo/ssl/secure.net.key SSLCACertificateFile /home/foo/ssl/ca.txt </VirtualHost> <VirtualHost 4.4.4.4:443> ServerName secure.org DocumentRoot /home/foo/secure.org SSLEngine on SSLCertificateFile /home/foo/ssl/secure.org.crt SSLCertificateKeyFile /home/foo/ssl/secure.org.key SSLCACertificateFile /home/foo/ssl/ca.txt </VirtualHost> For what it's worth, I prefer to have each of my SSL sites on their own IP instead of including one of them on the primary VHOST IP. Any links which show a standard setup would be more than welcome!

  • How do I block IP addresses in SuSEFirewall?

    - by Evgeny
    Does SuSEfirewall in OpenSuSE 11 provide an easy way to block all traffic from a list of IP addresses? Ideally just a textfile into which I can put all IP addresses I want blocked, otherwise some configuration option. I've looked through /etc/sysconfig/SuSEfirewall2, but haven't been able to find anything like that.

  • Will small random dynamic snippets break caching

    - by Saif Bechan
    I am busy writing a WordPress plugin. Now most users have cache plugins installed, they cache the pages. I know also some webservers as nginx have php caching and whatnot. There are also things like memcached. Now I have to admit I do not know exactly how they work, if anyone have some good links on how they work I would be glad. Some links where it's explained simple, not to technical. Now the question. My plugin displays different statistics on posts, they are always different, will this break the caching of the page. To take is a step further, sometimes the statistics of the post needs updating, and there is a small javascript snippet added to the page. Now will these two action result in the page not caching, or am I ok.
