  • Set-Cookie Headers getting stripped in ASP.NET HttpHandlers

    - by Rick Strahl
    Yikes, I ran into a real bummer of an edge case yesterday in one of my older low level handler implementations (for West Wind Web Connection in this case). Basically this handler is a connector for a backend Web framework that creates self contained HTTP output. An ASP.NET Handler captures the full output, and then shoves the result down the ASP.NET Response object pipeline writing out the content into the Response.OutputStream and seperately sending the HttpHeaders in the Response.Headers collection. The headers turned out to be the problem and specifically Http Cookies, which for some reason ended up getting stripped out in some scenarios. My handler works like this: Basically the HTTP response from the backend app would return a full set of HTTP headers plus the content. The ASP.NET handler would read the headers one at a time and then dump them out via Response.AppendHeader(). But I found that in some situations Set-Cookie headers sent along were simply stripped inside of the Http Handler. After a bunch of back and forth with some folks from Microsoft (thanks Damien and Levi!) I managed to pin this down to a very narrow edge scenario. It's easiest to demonstrate the problem with a simple example HttpHandler implementation. The following simulates the very much simplified output generation process that fails in my handler. Specifically I have a couple of headers including a Set-Cookie header and some output that gets written into the Response object.using System.Web; namespace wwThreads { public class Handler : IHttpHandler { /* NOTE: * * Run as a web.config set handler (see entry below) * * Best way is to look at the HTTP Headers in Fiddler * or Chrome/FireBug/IE tools and look for the * WWHTREADSID cookie in the outgoing Response headers * ( If the cookie is not there you see the problem! ) */ public void ProcessRequest(HttpContext context) { HttpRequest request = context.Request; HttpResponse response = context.Response; // If ClearHeaders is used Set-Cookie header gets removed! // if commented header is sent... response.ClearHeaders(); response.ClearContent(); // Demonstrate that other headers make it response.AppendHeader("RequestId", "asdasdasd"); // This cookie gets removed when ClearHeaders above is called // When ClearHEaders is omitted above the cookie renders response.AppendHeader("Set-Cookie", "WWTHREADSID=ThisIsThEValue; path=/"); // *** This always works, even when explicit // Set-Cookie above fails and ClearHeaders is called //response.Cookies.Add(new HttpCookie("WWTHREADSID", "ThisIsTheValue")); response.Write(@"Output was created.<hr/> Check output with Fiddler or HTTP Proxy to see whether cookie was sent."); } public bool IsReusable { get { return false; } } } } In order to see the problem behavior this code has to be inside of an HttpHandler, and specifically in a handler defined in web.config with: <add name=".ck_handler" path="handler.ck" verb="*" type="wwThreads.Handler" preCondition="integratedMode" /> Note: Oddly enough this problem manifests only when configured through web.config, not in an ASHX handler, nor if you paste that same code into an ASPX page or MVC controller. What's the problem exactly? The code above simulates the more complex code in my live handler that picks up the HTTP response from the backend application and then peels out the headers and sends them one at a time via Response.AppendHeader. One of the headers in my app can be one or more Set-Cookie. I found that the Set-Cookie headers were not making it into the Response headers output. Here's the Chrome Http Inspector trace: Notice, no Set-Cookie header in the Response headers! Now, running the very same request after removing the call to Response.ClearHeaders() command, the cookie header shows up just fine: As you might expect it took a while to track this down. At first I thought my backend was not sending the headers but after closer checks I found that indeed the headers were set in the backend HTTP response, and they were indeed getting set via Response.AppendHeader() in the handler code. Yet, no cookie in the output. In the simulated example the problem is this line:response.AppendHeader("Set-Cookie", "WWTHREADSID=ThisIsThEValue; path=/"); which in my live code is more dynamic ( ie. AppendHeader(token[0],token[1[]) )as it parses through the headers. Bizzaro Land: Response.ClearHeaders() causes Cookie to get stripped Now, here is where it really gets bizarre: The problem occurs only if: Response.ClearHeaders() was called before headers are added It only occurs in Http Handlers declared in web.config Clearly this is an edge of an edge case but of course - knowing my relationship with Mr. Murphy - I ended up running smack into this problem. So in the code above if you remove the call to ClearHeaders(), the cookie gets set!  Add it back in and the cookie is not there. If I run the above code in an ASHX handler it works. If I paste the same code (with a Response.End()) into an ASPX page, or MVC controller it all works. Only in the HttpHandler configured through Web.config does it fail! Cue the Twilight Zone Music. Workarounds As is often the case the fix for this once you know the problem is not too difficult. The difficulty lies in tracking inconsistencies like this down. Luckily there are a few simple workarounds for the Cookie issue. Don't use AppendHeader for Cookies The easiest and obvious solution to this problem is simply not use Response.AppendHeader() to set Cookies. Duh! Under normal circumstances in application level code there's rarely a reason to write out a cookie like this:response.AppendHeader("Set-Cookie", "WWTHREADSID=ThisIsThEValue; path=/"); but rather create the cookie using the Response.Cookies collection:response.Cookies.Add(new HttpCookie("WWTHREADSID", "ThisIsTheValue")); Unfortunately, in my case where I dynamically read headers from the original output and then dynamically  write header key value pairs back  programmatically into the Response.Headers collection, I actually don't look at each header specifically so in my case the cookie is just another header. My first thought was to simply trap for the Set-Cookie header and then parse out the cookie and create a Cookie object instead. But given that cookies can have a lot of different options this is not exactly trivial, plus I don't really want to fuck around with cookie values which can be notoriously brittle. Don't use Response.ClearHeaders() The real mystery in all this is why calling Response.ClearHeaders() prevents a cookie value later written with Response.AppendHeader() to fail. I fired up Reflector and took a quick look at System.Web and HttpResponse.ClearHeaders. There's all sorts of resetting going on but nothing that seems to indicate that headers should be removed later on in the request. The code in ClearHeaders() does access the HttpWorkerRequest, which is the low level interface directly into IIS, and so I suspect it's actually IIS that's stripping the headers and not ASP.NET, but it's hard to know. Somebody from Microsoft and the IIS team would have to comment on that. In my application it's probably safe to simply skip ClearHeaders() in my handler. The ClearHeaders/ClearContent was mainly for safety but after reviewing my code there really should never be a reason that headers would be set prior to this method firing. However, if for whatever reason headers do need to be cleared, it's easy enough to manually clear the headers out:private void RemoveHeaders(HttpResponse response) { List<string> headers = new List<string>(); foreach (string header in response.Headers) { headers.Add(header); } foreach (string header in headers) { response.Headers.Remove(header); } response.Cookies.Clear(); } Now I can replace the call the Response.ClearHeaders() and I don't get the funky side-effects from Response.ClearHeaders(). Summary I realize this is a total edge case as this occurs only in HttpHandlers that are manually configured. It looks like you'll never run into this in any of the higher level ASP.NET frameworks or even in ASHX handlers - only web.config defined handlers - which is really, really odd. After all those frameworks use the same underlying ASP.NET architecture. Hopefully somebody from Microsoft has an idea what crazy dependency was triggered here to make this fail. IAC, there are workarounds to this should you run into it, although I bet when you do run into it, it'll likely take a bit of time to find the problem or even this post in a search because it's not easily to correlate the problem to the solution. It's quite possible that more than cookies are affected by this behavior. Searching for a solution I read a few other accounts where headers like Referer were mysteriously disappearing, and it's possible that something similar is happening in those cases. Again, extreme edge case, but I'm writing this up here as documentation for myself and possibly some others that might have run into this. © Rick Strahl, West Wind Technologies, 2005-2012Posted in ASP.NET   IIS7   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • GWB | Got Geekswithblogs Suggestions? Try UserVoice

    - by Staff of Geeks
    We have struggled in the past with different approaches of getting feedback from you as bloggers.  We really want to know what you would like to see, what other systems have that is helpful, and where we need to grow.  This community is made up of many different individuals so the system for feedback needed a voting or liking tool for us to gage what was a popular thought or just one guys request.  We would love to put every request in, but that would make the system function for some and unusable for others. This is where UserVoice comes in.  In a suggestion of features, Martin Hinshelwood suggested we give UserVoice a chance.  He had used it with other projects and sites and thought it would be a good feedback tool for Geekswithblogs.net.  We tried it out and agreed.  Give it a try and let us know what you want to see on Geekswithblogs.net and vote on other suggestions.  Feedback is key to the success of this community and we would love to hear what you have to say.   UserVoice for Geekswithblogs.net Feedback   Technorati Tags: UserVoice,Geekswithblogs,Feedback,Community

  • Snmpd update interface counters slowly or something like this

    - by Korjavin Ivan
    I update one my freebsd box to 9-stable (totally new installation) and install net-snmp for monitoring. uname -r 9.1-PRERELEASE pkg_info net-snmp-5.7.1_7 Information for net-snmp-5.7.1_7: Comment: An extendable SNMP implementation .... cat /var/db/ports/net-snmp/options # This file is auto-generated by 'make config'. # Options for net-snmp-5.7.1_7 _OPTIONS_READ=net-snmp-5.7.1_7 _FILE_COMPLETE_OPTIONS_LIST= IPV6 MFD_REWRITES PERL PERL_EMBEDDED PYTHON DUMMY TKMIB DMALLOC MYSQL AX_SOCKONLY UNPRIVILEGED OPTIONS_FILE_UNSET+=IPV6 OPTIONS_FILE_UNSET+=MFD_REWRITES OPTIONS_FILE_SET+=PERL OPTIONS_FILE_SET+=PERL_EMBEDDED OPTIONS_FILE_UNSET+=PYTHON OPTIONS_FILE_SET+=DUMMY OPTIONS_FILE_UNSET+=TKMIB OPTIONS_FILE_SET+=DMALLOC OPTIONS_FILE_UNSET+=MYSQL OPTIONS_FILE_UNSET+=AX_SOCKONLY OPTIONS_FILE_UNSET+=UNPRIVILEGED I have about 500 vlan on this machine, and collect info about interface through snmpd to 2 different software, zabbix and cacti. And both of them plot the graphs with blank fields. I tryed change polling time in zabbix, from 15, sec to 30,60,90,120,10. And anyway i have blank fields. snmpd.conf is empty - only a access controls. This configuration worked fine on freebsd 8. Where is my fault? How fix this graphs? UPD: Changing pooling time, switch off one of agent, doesnt help. I look at zabbix log (recieved data from snmpd) and see that: sorry for russian locale, just look at numbers: and thats is not true, as my "iftop" show speed was about 90Mbits, but snmpd return 2Mbits. I understand that snmpd doesnt return speed, it return just a counter. But how its possible? why 2Mbit/s ? I tryed recompile snmpd with 64-bit counters, and without it. In both variants this blank fields present. So i think its my OS (freebsd) doesnt update interface counters well. I still collect tcpdump for found this request/response. But have problem with that, to much trash. UPD2: I decrypt tcpdump-ed file, and public this as google doc at gdocfile Timediff looks strange.. Like zabbix sometimes "forget" do request, and then do twice at row, ehh UPD3: I parse log from command "while true; do netstat -bin -I vlan4008 /var/log/netstat; sleep 300; done" and load as google docs, and add formula for speed : link Looks like all counters in OS are good. Now i think problem in : 1. zabbix get request twice at row (and what about cacti) 2. snmpd use counter32

  • What is the correct way to deal with similar but independent features?

    - by Koviko
    Let's say we have a feature request come in and we begin work on it, which we'll call feature-1. It introduces some new logic to the application, which we'll call logic-A and logic-B. A programmer branches from the release branch and begins work on the feature. Soon after, we get another feature request, which we'll call feature-2. It will implement logic-A and logic-C into the application. The logic A being implemented by this feature is the same logic-A as was implemented in feature-1. Let's also say that given logic-B, logic-A might be implemented slightly differently than it would have been given logic-C, and also differently given both logic-B and logic-C (eg. with only one feature, the code would be less flexible than with both). How should this situation be handled? Concrete Example (to help with any confusion in my wording) feature-1 is a feed from programmers.stackexchange.com. feature-2 is a feed from gaming.stackexchange.com. logic-A is the implementation of a feed at all (assuming the application currently has no feeds), which links to the content as well and gives related information. logic-B is that the feed's source is from programmers.stackexchange.com. Adds to logic-A that the related programming language is displayed. logic-C is that the feed's source is from gaming.stackexchange.com. Adds to logic-A that the related game's name and box art is displayed.

  • ISPConfig 3 SSL automatic rewrite

    - by lol
    I was wondering how you could get apache2 to redirect http://server.com:8080 to https://server.com:8080 - I have an ISPConfig 3 setup and the http://server.com:8080 virtual host currently prints a 400 back request error given that I've tried adding RewriteEngine on RewriteCond %{HTTPS} !^on$ [NC] RewriteRule . https://%{HTTP_HOST}:8080%{REQUEST_URI} [L] to the ispconfig.vhost file (and reloading the conf) with no success --edit!-- I've been playing around with it and adding an 'always redirect to google' into the ispconfig vhost and it works once you've already started talking ssl to it. this means the non-ssl connections are getting 'bad request errors' before the vhost is loaded... but where...? --edit 2!-- nope, the ssl is handled exclusively by the virtual host - if I turn off the ssl engine then the rewriting works perfectly (but obviously there is no ssl at https://) thanks!

  • Setting up a very mixed Active Directory network to work with PowerShell Remote Administration

    - by erictheavg
    Summary: I want to be able to monitor the computers on my network, but don't need it to be automated. We're too small to purchase anything like MOM, but too big to do anything manually (~100 machines in two locations). I just keep running into issues, and was wondering if there's a master list of Group Policy settings I can distribute to my environment to get Remote Powershell working. Environment: Our AD network is pretty mixed. The end users have XP SP3, Win 7, and Win 7 x64. The servers include Win2k3 SP2, Win2k8, Win2k8 x64, Win2k8 R2, and Win2k8 R2 x64. Details: I'm trying to get it to work with Remote Powershell, but I run into errors like the following: Connecting to remote server failed with the following error message : The WinRM client cannot process the request. Default authentication may be used with an IP address under the following conditions: the transport is HTTPS or the destination is in the TrustedHosts list, and explicit credentials are provided. Use winrm.cmd to configure TrustedHosts. Note that computers in the TrustedHosts list might not be authenticated. For more information on how to set TrustedHosts run the following command: winrm help config. For more information, see the about_Remote_Troubleshooting Help topic. + CategoryInfo : OpenError: (:) [], PSRemotingTransportException + FullyQualifiedErrorId : PSSessionStateBroken Then I go to the computer (Win2k3 SP2 server) and run winrm quickconfig per the recommendations via google, and it says: Make these changes [y/n]? y WinRM has been updated to receive requests. WinRM service started. WSManFault Message = The client cannot connect to the destination specified in the request. Verify that the service on the destination is running and is accepting requests. Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM. If the destination is the WinRM service, run the following command on the destination to analyze and configure the WinRM service: "winrm quickconfig". Error number: -2144108526 0x80338012 The client cannot connect to the destination specified in the request. Verify that the service on the destination is running and is accepting requests. Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM. If the destination is the WinRM service, run the following command on the destination to analyze and configure the WinRM service: "winrm quickconfig". That's right. It tells me to remedy my winrm quickconfig failure by running winrm quickconfig. I don't want to band-aid this project one google search at a time. I'm sure there is a step-by-step tutorial out there on how to set up a network for powershell remote administration. Does anyone know of one? Books are acceptable. Thanks in advance! I didn't think my question would get this long.

  • Can I use nginx to start EC2 instances on demand?

    - by Gabe Hollombe
    TL;DR - Is there a way to make nginx act as an elastic load balancer that will spin up EC2 instances on demand, allowing for the case when periods of no demand mean no instances will be running? Longer explanation - I have an nginx server that proxy_pass'es requests to a server on EC2. This server doesn't get many requests, so I'd like to keep the server spun down during periods of inactivity (I already have a script to do this). Then, when the instance is spun down and nginx gets a request for that instance, it will time out when trying to get a response from it. At this point, can I somehow trigger a shell command on the server to use EC2's command line tools to spin up the instance, then re-try the user's request after it has started?

  • The Shift: how Orchard painlessly shifted to document storage, and how it’ll affect you

    - by Bertrand Le Roy
    We’ve known it all along. The storage for Orchard content items would be much more efficient using a document database than a relational one. Orchard content items are composed of parts that serialize naturally into infoset kinds of documents. Storing them as relational data like we’ve done so far was unnatural and requires the data for a single item to span multiple tables, related through 1-1 relationships. This means lots of joins in queries, and a great potential for Select N+1 problems. Document databases, unfortunately, are still a tough sell in many places that prefer the more familiar relational model. Being able to x-copy Orchard to hosters has also been a basic constraint in the design of Orchard. Combine those with the necessity at the time to run in medium trust, and with license compatibility issues, and you’ll find yourself with very few reasonable choices. So we went, a little reluctantly, for relational SQL stores, with the dream of one day transitioning to document storage. We have played for a while with the idea of building our own document storage on top of SQL databases, and Sébastien implemented something more than decent along those lines, but we had a better way all along that we didn’t notice until recently… In Orchard, there are fields, which are named properties that you can add dynamically to a content part. Because they are so dynamic, we have been storing them as XML into a column on the main content item table. This infoset storage and its associated API are fairly generic, but were only used for fields. The breakthrough was when Sébastien realized how this existing storage could give us the advantages of document storage with minimal changes, while continuing to use relational databases as the substrate. public bool CommercialPrices { get { return this.Retrieve(p => p.CommercialPrices); } set { this.Store(p => p.CommercialPrices, value); } } This code is very compact and efficient because the API can infer from the expression what the type and name of the property are. It is then able to do the proper conversions for you. For this code to work in a content part, there is no need for a record at all. This is particularly nice for site settings: one query on one table and you get everything you need. This shows how the existing infoset solves the data storage problem, but you still need to query. Well, for those properties that need to be filtered and sorted on, you can still use the current record-based relational system. This of course continues to work. We do however provide APIs that make it trivial to store into both record properties and the infoset storage in one operation: public double Price { get { return Retrieve(r => r.Price); } set { Store(r => r.Price, value); } } This code looks strikingly similar to the non-record case above. The difference is that it will manage both the infoset and the record-based storages. The call to the Store method will send the data in both places, keeping them in sync. The call to the Retrieve method does something even cooler: if the property you’re looking for exists in the infoset, it will return it, but if it doesn’t, it will automatically look into the record for it. And if that wasn’t cool enough, it will take that value from the record and store it into the infoset for the next time it’s required. This means that your data will start automagically migrating to infoset storage just by virtue of using the code above instead of the usual: public double Price { get { return Record.Price; } set { Record.Price = value; } } As your users browse the site, it will get faster and faster as Select N+1 issues will optimize themselves away. If you preferred, you could still have explicit migration code, but it really shouldn’t be necessary most of the time. If you do already have code using QueryHints to mitigate Select N+1 issues, you might want to reconsider those, as with the new system, you’ll want to avoid joins that you don’t need for filtering or sorting, further optimizing your queries. There are some rare cases where the storage of the property must be handled differently. Check out this string[] property on SearchSettingsPart for example: public string[] SearchedFields { get { return (Retrieve<string>("SearchedFields") ?? "") .Split(new[] {',', ' '}, StringSplitOptions.RemoveEmptyEntries); } set { Store("SearchedFields", String.Join(", ", value)); } } The array of strings is transformed by the property accessors into and from a comma-separated list stored in a string. The Retrieve and Store overloads used in this case are lower-level versions that explicitly specify the type and name of the attribute to retrieve or store. You may be wondering what this means for code or operations that look directly at the database tables instead of going through the new infoset APIs. Even if there is a record, the infoset version of the property will win if it exists, so it is necessary to keep the infoset up-to-date. It’s not very complicated, but definitely something to keep in mind. Here is what a product record looks like in Nwazet.Commerce for example: And here is the same data in the infoset: The infoset is stored in Orchard_Framework_ContentItemRecord or Orchard_Framework_ContentItemVersionRecord, depending on whether the content type is versionable or not. A good way to find what you’re looking for is to inspect the record table first, as it’s usually easier to read, and then get the item record of the same id. Here is the detailed XML document for this product: <Data> <ProductPart Inventory="40" Price="18" Sku="pi-camera-box" OutOfStockMessage="" AllowBackOrder="false" Weight="0.2" Size="" ShippingCost="null" IsDigital="false" /> <ProductAttributesPart Attributes="" /> <AutoroutePart DisplayAlias="camera-box" /> <TitlePart Title="Nwazet Pi Camera Box" /> <BodyPart Text="[...]" /> <CommonPart CreatedUtc="2013-09-10T00:39:00Z" PublishedUtc="2013-09-14T01:07:47Z" /> </Data> The data is neatly organized under each part. It is easy to see how that document is all you need to know about that content item, all in one table. If you want to modify that data directly in the database, you should be careful to do it in both the record table and the infoset in the content item record. In this configuration, the record is now nothing more than an index, and will only be used for sorting and filtering. Of course, it’s perfectly fine to mix record-backed properties and record-less properties on the same part. It really depends what you think must be sorted and filtered on. In turn, this potentially simplifies migrations considerably. So here it is, the great shift of Orchard to document storage, something that Orchard has been designed for all along, and that we were able to implement with a satisfying and surprising economy of resources. Expect this code to make its way into the 1.8 version of Orchard when that’s available.

  • SuperMicro IPMI through OpenBSD PF Firewall

    - by thelsdj
    I'm trying to access a SuperMicro IPMI card that is behind an OpenBSD bridged firewall. A couple pieces of information: The OpenBSD firewall itself has a SuperMicro IPMI that I can access across the internet. The IPMI I'm trying to reach can be reached from behind the firewall. My gateway does arp request the IPMI and it does appear to respond (this is from the external interface of the firewall) 16:57:45.548892 arp who-has ipminame tell gwname 16:57:45.549500 arp reply ipminame is-at ipmimac But when I make a request to the IPMI IP from outside the firewall the external interface of the firewall shows no traffic with the IPMI ip as its destination. Any idea what might be causing this problem? Is there something about IPMI traffic that my gateway wouldn't like (the gateway is provided by my colocation provider so I can't easily debug it).

  • NFS Client reports Permission Denied, Server reports Permission Granted

    - by VxJasonxV
    I have two RedHat 4 Servers. The client is 4.6, the server is 4.5. I'm attempting to mount a share from the server, onto the client via NFS. The /etc/exports configuration is as follows: /opt/data/config bkup(rw,no_root_squash,async) /opt/data/db bkup(rw,no_root_squash,async) exportfs returns these (among other) shares, nfs is running according to ps output. I've been attempting to use autofs on the client, but have opted to just mount the share manually considering the issues I'm having. So, I issue the mount request: mount dist:/opt/data/config /mnt/config mount: dist:/opt/data/config failed, reason given by server: Permission denied Ok, so let's see what the server has to say for itself. May 6 23:17:55 dist mountd[3782]: authenticated mount request from bkup:662 for /opt/data/config (/opt/data/config) It says it allowed the mount to take place. How can I diagnose why the client and server are disagreeing on the result?

  • robot hammering apache2

    - by user1571418
    My apache2 log is bombarded with lines like: 108.5.114.118 - - [03/Aug/2012:15:23:28 +0200] "GET http://xchecker.net/tmp_proxy2012/http/engine.php HTTP/1.0" 404 1690 "http://xchecker.net/tmp_proxy2012/http/engine.php" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; Win 9x 4.90)" I am puzzled by this -- why is a request for some weird xchecker.net domain ending up on my server in the first place?! The request comes every few dozens of seconds, must be a robot. Any ideas what it is? Btw that URL is valid -- apparently it contains some test page...

  • Need IP port forwarding to access an internel service running on an internal machine

    - by appleluo
    I am trying to configure iptables to do port forwarding for certain request. The scenario is like this: Login node A can be accessed from outside Compute node B that running the service can be accessed from A but not from outside. I want to set up iptables so that a request for the service on B from outside can be accessed through A. A has two ethernet ports: Internal eth0, with ip internal_A and External eth1, with ip external_A. B has 1 ethernet port, internal eth0. let's say its ip is internal_B The service listens to internal_B:5900. We open external_A:10000 for user access. I configure my iptables with the following commands: echo 1> /proc/sys/net/ipv4/ip_forward /sbin/iptables -P FORWARD ACCEPT /sbin/iptables -t nat -A POSTROUTING -j MASQUERADE /sbin/iptables -A PREROUTING -p tcp -t nat --dport 10000 -j DNAT --to-destination interal_B:5900 /sbin/iptables -A OUTPUT -p tcp -t nat -d external_A --dport 10000 -j DNAT --to-destination internal_B:5900 But it didn't work. Can anybody help me?

    i don't have enough knowledge about storage systems but have to tell my audiences about how storage works in organization data centers. For this purpose to keep things simple, first i want to show them a layer model then from top to bottom and then i want to explore all these layers. What i mean by layered model in storage architecture? i want to start my presentation something like that, first layer can be applications, application request a data from storage and then ... ... (the topics i want to cover are file sytems, metadata,the physical implementation of storage (das, nas etc.) ... the request comes to the storage device and storage device (depends on the technology) goes through the disk and disk send back the data using iscsi protol, we can say that the iscsi protocol managing the path between... ... if you help me explain these steps layer by layer by examples and key technologies to be defined, really appreciate it. thanks.

  • Java HttpURLConnection class Program

    - by pandu
    I am learning java. Here is the sample code of HttpURLConnection class usage in some text book import java.net.*; import java.io.*; import java.util.*; class HttpURLDemo { public static void main(String args[]) throws Exception { URL hp = new URL("http://www.google.com"); HttpURLConnection hpCon = (HttpURLConnection) hp.openConnection(); // Display request method. System.out.println("Request method is " + hpCon.getRequestMethod()); // Display response code. System.out.println("Response code is " + hpCon.getResponseCode()); // Display response message. System.out.println("Response Message is " + hpCon.getResponseMessage()); // Get a list of the header fields and a set // of the header keys. Map<String, List<String>> hdrMap = hpCon.getHeaderFields(); Set<String> hdrField = hdrMap.keySet(); System.out.println("\nHere is the header:"); // Display all header keys and values. for(String k : hdrField) { System.out.println("Key: " + k + " Value: " + hdrMap.get(k)); } } } Question is Why hpCon Object is declared in the following way? HttpURLConnection hpCon = (HttpURLConnection) hp.openConnection(); instead of declaring like this HttpURLConnection hpCon = new HttpURLConnection(); Author provided the following explanation. I cant understand Java provides a subclass of URLConnection that provides support for HTTP connections. This class is called HttpURLConnection. You obtain an HttpURLConnection in the same way just shown, by calling openConnection( ) on a URL object, but you must cast the result to HttpURLConnection. (Of course, you must make sure that you are actually opening an HTTP connection.) Once you have obtained a reference to an HttpURLConnection object, you can use any of the methods inherited from URLConnection

  • mod_fcgid process doesn't respawn

    - by aaronsw
    I have a Python script running on my server as a FastCGI using Apache2 and mod_fcgid. I let it spawn up to five processes. But I soon get messages like these in the Apache logs: [Wed Sep 02 23:16:34 2009] [warn] (103)Software caused connection abort: mod_fcgid: ap_pass_brigade failed in handle_request function [Wed Sep 02 23:16:35 2009] [warn] (103)Software caused connection abort: mod_fcgid: ap_pass_brigade failed in handle_request function and then Apache doesn't seem to recognize that all its processes are dead (I have a max of 5 backends) and refuses to spawn new ones: [Wed Sep 02 23:26:16 2009] [notice] mod_fcgid: /var/www/hacks.og.theinfo.org/picker.fcgi total process count 5 >= 5, skip the spawn request [Wed Sep 02 23:26:17 2009] [notice] mod_fcgid: /var/www/hacks.og.theinfo.org/picker.fcgi total process count 5 >= 5, skip the spawn request at which point it refuses to respond to requests from the outside world.

  • Throttle connections to web service if load gets too high?

    - by Joseph Turian
    I have a web site that communicates via XMLRPC with an XMLRPC server web service. (The web service is written in Python using xmlrpclib.) I believe that xmlrpclib will block while it is handling one request. So if there are three users with an xmlrpclib request ahead of you, your response takes four times as long. How do I handle it if I receive too many XMLRPC requests and the web service gets bogged down and has slow response time? If I am getting slashdotted, my preferred behavior is that the first users get good response times and everyone else is told to come back later. I think this is superior to giving everyone terrible response times. How do I create this behavior? Is this called load-balancing? I am not actually balancing though, until I have multiple servers.

  • AT&T DSL 2701HG-B Modem, port forwarding to RealVNC

    - by Paula
    Our old cable modem could easily be set up to forward an "incoming port request" to the RealVNC software. Allowing us to log into our home computer from any location. We don't see any such configuration possiblity with our new AT&T DSL 2Wire 2701HG-B modem. (And it appears to have 2 entirely different 'set up screens'. Why?) Where is the screen that allows "forward incoming request for a certain port", to a certain computer, and direct it towards RealVNC"?

  • New release of Microsoft All-In-One Code Framework is available for download - March 2011

    - by Jialiang
    A new release of Microsoft All-In-One Code Framework is available on March 8th. Download address: http://1code.codeplex.com/releases/view/62267#DownloadId=215627 You can download individual code samples or browse code samples grouped by technology in the updated code sample index. If it’s the first time that you hear about Microsoft All-In-One Code Framework, please read this Microsoft News Center article http://www.microsoft.com/presspass/features/2011/jan11/01-13codeframework.mspx, or watch the introduction video on YouTube http://www.youtube.com/watch?v=cO5Li3APU58, or read the introduction on our homepage http://1code.codeplex.com/. -------------- New Silverlight code samples CSSLTreeViewCRUDDragDrop Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215808 The code sample was created by Amit Dey. It demonstrates a custom TreeView with added functionalities of CRUD (Create, Read, Update, Delete) and drag-and-drop operations. Silverlight TreeView control with CRUD and drag & drop is a frequently asked programming question in Silverlight  forums. Many customers also requested this code sample in our code sample request service. We hope that this sample can reduce developers' efforts in handling this typical programming scenario. The following blog article introduces the sample in detail: http://blogs.msdn.com/b/codefx/archive/2011/02/15/silverlight-treeview-control-with-crud-and-drag-amp-drop.aspx. CSSL4FileDragDrop and VBSL4FileDragDrop Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215809 http://1code.codeplex.com/releases/view/62253#DownloadId=215810 The code sample demonstrates the new drag&drop feature of Silverlight 4 to implement dragging picures from the local file system to a Silverlight application.   Sometimes we want to change SiteMapPath control's titles and paths according to Query String values. And sometimes we want to create the SiteMapPath dynamically. This code sample shows how to achieve these goals by handling SiteMap.SiteMapResolve event. CSASPNETEncryptAndDecryptConfiguration, VBASPNETEncryptAndDecryptConfiguration Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215027 http://1code.codeplex.com/releases/view/62253#DownloadId=215106 In this sample, we encrypt and decrypt some sensitive information in the config file of a web application by using the RSA asymmetric encryption. This project contains two snippets. The first one demonstrates how to use RSACryptoServiceProvider to generate public key and the corresponding private key and then encrypt/decrypt string value on page. The second part shows how to use RSA configuration provider to encrypt and decrypt configuration section in web.config of web application. connectionStrings section in plain text: Encrypted connectionString:  Note that if you store sensitive data in any of the following configuration sections, we cannot encrypt it by using a protected configuration provider <processModel> <runtime> <mscorlib> <startup> <system.runtime.remoting> <configProtectedData> <satelliteassemblies> <cryptographySettings> <cryptoNameMapping> CSASPNETFileUploadStatus Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215028 I believe ASP.NET programmers will like this sample, because in many cases we need customers know the current status of the uploading files, including the upload speed and completion percentage and so on. Under normal circumstances, we need to use COM components to accomplish this function, such as Flash, Silverlight, etc. The uploading data can be retrieved in two places, the client-side and the server-side. For the client, for the safety factors, the file upload status information cannot be got from JavaScript or server-side code, so we need COM component, like Flash and Silverlight to accomplish this, I do not like this approach because the customer need to install these components, but also we need to learn another programming framework. For the server side, we can get the information through coding, but the key question is how to tell the client results. In this case, We will combine custom HTTPModule and AJAX technology to illustrate how to analyze the HTTP protocol, how to break the file request packets, how to customize the location of the server-side file caching, how to return the file uploading status back to the client and so on . CSASPNETHighlightCodeInPage, VBASPNETHighlightCodeInPage Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215029 http://1code.codeplex.com/releases/view/62253#DownloadId=215108 This sample imitates a system that needs display the highlighted code in an ASP.NET page . As a matter of fact, sometimes we input code like C# or HTML in a web page and we need these codes to be highlighted for a better reading experience. It is convenient for us to keep the code in mind if it is highlighted. So in this case, the sample shows how to highlight the code in an ASP.NET page. It is not difficult to highlight the code in a web page by using String.Replace method directly. This  method can return a new string in which all occurrences of a specified string in the current instance are replaced with another specified string. However, it may not be a good idea, because it's not extremely fast, in fact, it's pretty slow. In addition, it is hard to highlight multiple keywords by using String.Replace method directly. Sometimes we need to copy source code from visual studio to a web page, for readability purpose, highlight the code is important while set the different types of keywords to different colors in a web page by using String.Replace method directly is not available. To handle this issue, we need to use a hashtable variable to store the different languages of code and their related regular expressions with matching options. Furthermore, define the css styles which used to highlight the code in a web page. The sample project can auto add the style object to the matching string of code. A step-by-step guide illustrating how to highlight the code in an ASP.NET page: 1. the HighlightCodePage.aspx page Choose a type of language in the dropdownlist control and paste the code in the textbox control, then click the HighLight button. 2.  Display the highlighted code in an ASP.NET page After user clicks the HighLight button, the highlighted code will be displayed at right side of the page.        CSASPNETPreventMultipleWindows Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215032 This sample demonstrates a step-by-step guide illustrating how to detect and prevent multiple windows or tab usage in Web Applications. The sample imitates a system that need to prevent multiple windows or tabs to solve some problems like sharing sessions, protect duplicated login, data concurrency, etc. In fact, there are many methods achieving this goal. Here we give a solution of use JavaScript, Sample shows how to use window.name property check the correct links and throw other requests to invalid pages. This code-sample use two user controls to make a distinction between base page and target page, user only need drag different controls to appropriate web form pages. so user need not write repetitive code in every page, it will make coding work lightly and convenient for modify your code.  JSVirtualKeyboard Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215093 This article describes an All-In-One framework sample that demonstrates a step-by-step guide illustrating how to build a virtual keyboard in your HTML page. Sometimes we may need to offer a virtual keyboard to let users input something without their real keyboards. This scenario often occurs when users will enter their password to get access to our sites and we want to protect the password from some kinds of back-door software, a Key-logger for example, and we will find a virtual keyboard on the page will be a good choice here. To create a virtual keyboard, we firstly need to add some buttons to the page. And when users click on a certain button, the JavaScript function handling the onclick event will input an appropriated character to the textbox. That is the simple logic of this feature. However, if we indeed want a virtual keyboard to substitute for the real keyboard completely, we will need more advanced logic to handle keys like Caps-Lock and Shift etc. That will be a complex work to achieve. CSASPNETDataListImageGallery Download: http://1code.codeplex.com/releases/view/62261#DownloadId=215267 This code sample demonstrates how to create an Image Gallery application by using the DataList control in ASP.NET. You may find the Image Gallery is widely used in many social networking sites, personal websites and E-Business websites. For example, you may use the Image Gallery to show a library of personal uploaded images on a personal website. Slideshow is also a popular tool to display images on websites. This code sample demonstrates how to use the DataList and ImageButton controls in ASP.NET to create an Image Gallery with image navigation. You can click on a thumbnail image in the Datalist control to display a larger version of the image on the page. This sample code reads the image paths from a certain directory into a FileInfo array. Then, the FileInfo array is used to populate a custom DataTable object which is bound to the Datalist control. This code sample also implements a custom paging system that allows five images to be displayed horizontally on one page. The following link buttons are used to implement a custom paging system:   •     First •     Previous •     Next •     Last Note We recommend that you use this method to load no more than five images at a time. You can also set the SelectedIndex property for the DataList control to limit the number of the thumbnail images that can be selected. To indicate which image is selected, you can set the SelectedStyle property for the DataList control. VBASPNETSearchEngine Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215112 This sample shows how to implement a simple search engine in an ASP.NET web site. It uses LIKE condition in SQL statement to search database. Then it highlights keywords in search result by using Regular Expression and JavaScript.

  • Relaying requests between third party server and Heroku for static IP

    - by Gady
    I have a rails application hosted on Heroku that I need to integrate with 3rd party payments provider. The payment provider requires that my application will have a static IP for incoming and outgoing HTTPS requests. I want to deploy a proxy on a Linode VPS so it can relay the information as a proxy. Relaying the request to the service provider seems easy, I just use their IP. Can I relay requests coming from the service provider to the heroku application? Can I realy the request using a URL (https://myapp.herokuapp.com) ? What is the recommended proxy server to use?
