• WCF Service, Java JApplet client, transport error 405

  - by Juan Zamudio

  Hi all, I'm having a problem with a WCF Service and Java Client, I will try to give as much information as i can, thanks for your time. The Endpoint of the server is BasicHttpBinding, I tried hosting the server as a Windows Service and in IIS but nothing changed. The weird thing is that the Client works great if I use a simple class, in the moment I switch the class to an JApplet I get the problem mentioned. I'm using Eclipse as an IDE, I tried Axis and Metro to generate the stub with the same bad results. Here is an example of the Java class where everything is working public class TestSoaMetro { public String TestMethod(){ String result=null; IDigitalSignatureService aa = new DigitalSignatureService().getBasicHttpBindingEndpoint(); try { result= aa.getData("1", "id002962"); } catch (IDigitalSignatureServiceGetDataArgumentExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IDigitalSignatureServiceGetDataInvalidOperationExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } return result; } } Here is the example of the JApplet where I get the error: public class TestSoaMetroApplet extends JApplet { public void init() { Container content = getContentPane(); content.setBackground(Color.white); content.setLayout(new FlowLayout()); String result= this.TestMethod(); JLabel label = new JLabel(result); content.add(label); } public String TestMethod(){ String result=null; IDigitalSignatureService aa = null; try { aa = new DigitalSignatureService().getBasicHttpBindingEndpoint(); result= aa.getData("1", "id002962"); } catch (IDigitalSignatureServiceGetDataArgumentExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IDigitalSignatureServiceGetDataInvalidOperationExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } return result; } } In the moment the Applet loads I get the error, is the exact same call so I don't understand why I get the exception using the Applet. I Also tried to call this from a Silverlight client and I was getting a security exception, this is where I found out about clientaccesspolicy.xml and crossdomain.xml, I added clientaccesspolicy.xml to the service and the Silverlight Client works great, so I decided to try crossdomain.xml and nothing, the Applet still does not work. I will put the stack trace at the end, thanks all for your time.

• Poor home office network performance and cannot figure out where the issue is

  - by Jeff Willener

  This is the most bizarre issue. I have worked with small to mid size networks for quite a long time and can say I'm comfortable connecting hardware. Where you will start to lose me is with managed switches and firewalls. To start, let me describe my network (sigh, shouldn't but I MUST solve this). 1) Comcast Cable Internet 2) Motorola SURFboard eXtreme Cable Modem. a) Model: SB6120 b) DOCSIS 3.0 and 2.0 support c) IPv4 and IPv6 support 3-A) Cisco Small Business RV220W Wireless N Firewall a) Latest firmware b) Model: RV220W-A-K9-NA c) WAN Port to Modem (2) d) vlan 1: work e) vlan 2: everything else. 3-B) D-Link DIR-615 Draft 802.11 N Wireless Router a) Latest firmware b) WAN Port to Modem (2) 4) Servers connected directly to firewall a) If firewall 3-A, then vlan 1 b) CAT5e patch cables c) Dell PowerEdge 1400SC w/ 10/100 integrated NIC (Domain Controller, DNS, former DHCP) d) Dell PowerEdge 400SC w/ 10/100/1000 integrated NIC (VMWare Server) 4) Linksys EZXS88W unmanaged Workgroup 10/100 Switch a) If firewall 3-A, then vlan 2 b) 25' CAT5e patch cable to firewall (3-A or 3-B) c) Connects xBox 360, Blu-Ray player, PC at TV 5) Office equipment connected directly to firewall a) If firewall 3-A, then vlan 1 b) ~80' CAT6 or CAT5e patch cable to firewall (3-A or 3-B) c) Connects 1) Dell Latitude laptop 10/100/1000 2) Dell Inspiron laptop 10/100 3) Dell Workstation 10/100/1000 (Pristine host, VMWare Workstation 7.x with many bridged VM's) 4) Brother Laser Printer 10/100 5) Epson All-In-One Workforce 310 10/100 5-A) NetGear FS116 unmanaged 10/100 switch a) I've had this switch for a long time and never had issues. 5-B) NetGear GS108 unmanaged 10/100/1000 switch a) Bought new for this issue and returned. 5-C) Linksys SE2500 unmanaged 10/100/1000 switch a) Bought new for this issue and returned. 5-D) TP-Link TL-SG10008D unmanaged 10/100/1000 a) Bought new for this issue and still have. 6) VLan 1 Wireless Connections (on same subnet if 3-B) a) Any of those at 5c b) HP Laptop 7) VLan 2 Wireless Connection (on same subnet if 3-B) a) IPad, IPod b) Compaq Laptop c) Epson Wireless Printer Shew, without hosting a diagram I hope that paints a good picture. The Issue The breakdown here is at item 5. No matter what I do I cannot have a switch at 5 and have to run everything wireless regardless of router. Issues related to using a switch (point 5 above) SpeedTest is good. Poor throughput to other devices if can communicate at all. Usually cannot ping other devices even on the same switch although, when able, ping times are good. Eventual lose of connectivity and can "sometimes" be restored by unplugging everything for several days, not minutes or hours but we're talking a week if at all. Directly connect to computer gives good internet connection however throughput to other devices connected to firewall is at best horrible. Yet printing doesn't seem to be an issue as long as they are connected via wireless. I have to force the RV220W to 1000Mb on the respective port if using a Gig Switch Issues related to using wireless in place of a switch (point 5 above) Poor throughput to other devices if can communicate. SpeedTest is good. Bottom line Internet speeds are awesome. By the way, Comcast went WAY above and beyond to make sure it was not them. They rewired EVERYTHING which did solve internet drops. Computer to computer connections are garbage Cannot get switch at 5 to work, yet other at 4 has never had an issue. Direct connection, bypass switch, is good for DHCP and internet. DNS must be on server, not firewall. Cisco insists its my switches but as you can see I have used four and two different cables with the same result. My gut feeling is something is happening with routing. But I'm not smart enough to know that answer. I run a lot of VM's at 5-c-3, could that cause it? What's different compared to my previous house is I have introduced Gigabit hardware (firewall/switches/computers). Some of my computers might have IPv6 turned on if I haven't turned it off already. I'm truly at a loss and hope anyone has some crazy idea how to solve this. Bottom line, I need a switch in my office behind the firewall. I've changed everything. The real crux is I will find a working solution and, again, after days it will stop working. So this means I cannot isolate if its a computer since I have to use them. Oh and a solution is not throwing more money at this. I'm well into $1k already. Yah, lame.

• How to pre-load all deployed assemblies for an AppDomain

  - by Andras Zoltan

  Given an App Domain, there are many different locations that Fusion (the .Net assembly loader) will probe for a given assembly. Obviously, we take this functionality for granted and, since the probing appears to be embedded within the .Net runtime (Assembly._nLoad internal method seems to be the entry-point when Reflect-Loading - and I assume that implicit loading is probably covered by the same underlying algorithm), as developers we don't seem to be able to gain access to those search paths. My problem is that I have a component that does a lot of dynamic type resolution, and which needs to be able to ensure that all user-deployed assemblies for a given AppDomain are pre-loaded before it starts its work. Yes, it slows down startup - but the benefits we get from this component totally outweight this. The basic loading algorithm I've already written is as follows. It deep-scans a set of folders for any .dll (.exes are being excluded at the moment), and uses Assembly.LoadFrom to load the dll if it's AssemblyName cannot be found in the set of assemblies already loaded into the AppDomain (this is implemented inefficiently, but it can be optimized later): void PreLoad(IEnumerable<string> paths) { foreach(path p in paths) { PreLoad(p); } } void PreLoad(string p) { //all try/catch blocks are elided for brevity string[] files = null; files = Directory.GetFiles(p, "*.dll", SearchOption.AllDirectories); AssemblyName a = null; foreach (var s in files) { a = AssemblyName.GetAssemblyName(s); if (!AppDomain.CurrentDomain.GetAssemblies().Any( assembly => AssemblyName.ReferenceMatchesDefinition( assembly.GetName(), a))) Assembly.LoadFrom(s); } } LoadFrom is used because I've found that using Load() can lead to duplicate assemblies being loaded by Fusion if, when it probes for it, it doesn't find one loaded from where it expects to find it. So, with this in place, all I now have to do is to get a list in precedence order (highest to lowest) of the search paths that Fusion is going to be using when it searches for an assembly. Then I can simply iterate through them. The GAC is irrelevant for this, and I'm not interested in any environment-driven fixed paths that Fusion might use - only those paths that can be gleaned from the AppDomain which contain assemblies expressly deployed for the app. My first iteration of this simply used AppDomain.BaseDirectory. This works for services, form apps and console apps. It doesn't work for an Asp.Net website, however, since there are at least two main locations - the AppDomain.DynamicDirectory (where Asp.Net places it's dynamically generated page classes and any assemblies that the Aspx page code references), and then the site's Bin folder - which can be discovered from the AppDomain.SetupInformation.PrivateBinPath property. So I now have working code for the most basic types of apps now (Sql Server-hosted AppDomains are another story since the filesystem is virtualised) - but I came across an interesting issue a couple of days ago where this code simply doesn't work: the nUnit test runner. This uses both Shadow Copying (so my algorithm would need to be discovering and loading them from the shadow-copy drop folder, not from the bin folder) and it sets up the PrivateBinPath as being relative to the base directory. And of course there are loads of other hosting scenarios that I probably haven't considered; but which must be valid because otherwise Fusion would choke on loading the assemblies. I want to stop feeling around and introducing hack upon hack to accommodate these new scenarios as they crop up - what I want is, given an AppDomain and its setup information, the ability to produce this list of Folders that I should scan in order to pick up all the DLLs that are going to be loaded; regardless of how the AppDomain is setup. If Fusion can see them as all the same, then so should my code. Of course, I might have to alter the algorithm if .Net changes its internals - that's just a cross I'll have to bear. Equally, I'm happy to consider SQL Server and any other similar environments as edge-cases that remain unsupported for now. Any ideas!?

• Cyrus on CentOS with sasl / pam / ldap

  - by Oscar

  SASL/PAM/LDAP is driving me crazy... that's what I read a lot when googling for problems in this area, and what I experience myself :-S I'm trying to get Cyrus imap working for virtual hosting on CentOS with this authorisation backend and really don't know what's happening. In saslauthd I configured the LDAP search filter to use, but it looks like pam completely ignores it. Here's what I do for testing (done more tests but all with similar results): [root@testserv ~]# imtest -u [email protected] -a [email protected] WARNING: no hostname supplied, assuming localhost S: * OK [CAPABILITY IMAP4 IMAP4rev1 LITERAL+ ID STARTTLS] testserv.

The weird thing is, I do get an error when I rename or remove /etc/saslauthd.conf, but when the file exists it seems happily ignored... The filter in slapd.log seems to be taken from /etc/ldap.conf. Apart from some timers, that only contains: host 127.0.0.1 base o=mydomain,c=com pam_login_attribute mail Outcommenting the pam_login_attribute results in this filter in slapd.log: filter="([email protected])" Pam-imap looks like this: [root@testserv ~]# cat /etc/pam.d/imap auth required pam_ldap.so debug account required pam_ldap.so debug #auth sufficient pam_unix.so likeauth nullok #auth sufficient pam_ldap.so use_first_pass #auth required pam_deny.so #account sufficient pam_unix.so #account sufficient pam_ldap.so The outcommented stuff is because I don't have the cyrus admin user in Ldap; that's a Linux user. That works fine when uncommented, but I still need to play around with that a little and first I wanna get imap working.

• Mysql performance problem & Failed DIMM

  - by murdoch

  Hi I have a dedicated mysql database server which has been having some performance problems recently, under normal load the server will be running fine, then suddenly out of the blue the performance will fall off a cliff. The server isn't using the swap file and there is 12GB of RAM in the server, more than enough for its needs. After contacting my hosting comapnies support they have discovered that there is a failed 2GB DIMM in the server and have scheduled to replace it tomorow morning. My question is could a failed DIMM result in the performance problems I am seeing or is this just coincidence? My worry is that they will replace the ram tomorrow but the problems will persist and I will still be lost of explanations so I am just trying to think ahead. The reason I ask is that there is plenty of RAM in the server, more than required and simply missing 2GB should be a problem, so if this failed DIMM is causing these performance problems then the OS must be trying to access the failed DIMM and slowing down as a result. Does that sound like a credible explanation? This is what DELLs omreport program says about the RAM, notice one dimm is "Critical" Memory Information Health : Critical Memory Operating Mode Fail Over State : Inactive Memory Operating Mode

• I'm trying to run some PHP scripts as CLI instead of over HTTP. How do I make them play nice?

  - by gnfti

  Hi everyone. I'm using some PHP scripts from FeedForAll to join together RSS feeds (RSSmesh) and display them as HTML (RSS2HTML). Because I intend to run these scripts fairly intensively and don't want the resulting HTTP requests and bandwidth to count towards my hosting quota, I am in the process of moving to running them on the web host's server in an umbrella PHP "batch" script, and call this script via cron (this is a Linux server, by the way). Here's a (working) sample request over HTTP: http://www.mydomain.com/a/rss2htmlcore/rss2html2.php?XMLFILE=http://www.mydomain.com/a/myapp/xmlcache/feed.xml&TEMPLATE=template.html This will produce the desired HTML output. An example of how I want this to work on the command line: /srv/customers/mycustomer#/mydomain.com/www/a/rss2htmlcore/rss2html2-cli.php /srv/customers/mycustomer#/mydomain.com/www/a/myapp/xmlcache/feed.xml /srv/customers/mycustomer#/mydomain.com/www/a/template.html This is with the correct shebang line added to "rss2html2-cli.php". I could just as well specify the executable ("/usr/local/bin/php") in the request, I doubt it makes a difference because I am able to run another script (that I wrote myself) either way without problems. Now, RSS2HTML and RSSmesh are different in that, for starters, they include secondary files -- for example, both include an XML parser script -- and I suspect that this is where I am getting a bit in over my head. Right now I'm calling exec() from the "umbrella" batch script, like so: exec("/srv/customers/mycustomer#/mydomain.com/www/a/rss2htmlcore/rss2html2-cli.php /srv/customers/mycustomer#/mydomain.com/www/a/myapp/xmlcache/feed.xml /srv/customers/mycustomer#/mydomain.com/www/a/template.html", $output) But no output is being produced. What's the best way to go about this and what "gotchas" should I keep in mind? Is exec() the right way to approach this? It works fine for the other (simple) script but that writes its own output. For this I want to get the output and write it to a file from within the umbrella script if possible. I've also tried output buffering but to no avail. Do I need to pay attention to anything specific with regard to the includes? Right now they're specified in the scripts as include_once("FeedForAll_XMLParser.inc.php"); and the specified files are indeed in the same folder. Further info: -This is a Linux server. -I have no direct access to the shell, so I can't test things directly on a command line, everything is via crontab. -I will admit that support for the FeedForAll scripts leaves a lot to be desired, but I'd like to keep using their scripts if at all possible, if only because I know them and have been using them for a while. I have looked into Simplepie, but the FFA scripts do some things that I've seen no obvious solutions for with Simplepie, like limiting the number of items per individual feed (RSSmesh) or limiting the description length (RSS2HTML). -Yahoo! Pipes is out, they cache their data for too long for my application. Should you want to take a look at the code, here are the scripts as txt files. RSS2HTML2 and RSSmesh are the FeedForAll scripts, FeedForAll_XMLParser... is the included parser. Note that I have not yet amended these to handle $argv etc. I have however in "scraper-universal-rss-cli", which works fine with CLI. If anyone has any thoughts to share on this it would be very much appreciated. Thank you in advance.

• How to convert html textfield/area data to server-side txt file? [closed]

  - by olijake

  How can I make a script that will convert the text/data in a html textfield/textarea and send it to the server, which then saves it as a .txt file for storage? NOTE: I am hosting a website(for testing purposes) using Apache 2.2 on a Windows 7 machine. I downloaded PHP version 5.4.7, but have not yet installed on my server yet (not sure if I will need it, but also not sure how to install it). 1st problem: Saving text to server Html page/section with title textfield, text textarea, and submit button. You would enter a title, the text/notes you need in the textfield, then press the submit button to have it store the text in the textarea, as a .txt file on the server called .txt. 2nd problem: Opening text from server Html with list of all txt files OR textfield for entering in title, then submit button to send the title of the requested .txt file to the server, which would then load it up on the page. Here is what I have so far: (let me know if there is something that I should change or if something just isn't correct in the index.html code I have right now.) <!DOCTYPE HTML> <html> <head> <title>Insert Title</title> <meta http-equiv="Content-Type" content="Text/HTML; charset=UTF-8"/> </head> <body> <form method="post" action="save.INSERT_FILETYPE" name="textfile" enctype="multipart/form-data"> <input type="text" name="title"><br/> <textarea rows="20" cols="100" id="text" name="text"></textarea><br/> <input type="submit" name="submit" value="Submit Text to Server"> </form><br/> <hr style="width: 100%; height: 4px;"><br/> <form method="post" action="open.INSERT_FILETYPE" name="textfile" enctype="multipart/form-data"> <input type="text" name="title"><br/> <input type="submit" name="submit" value="Submit Txt File Request"> </form><br/> <div>Opened text file displays here or goes on another page</div> </body> </html> I plan on using a server side language/script, but ANYTHING that gets the job done is fine. I already tried looking into using some ASP/jScript/PHP, but have had some trouble implementing it into my server. (ie: getting the modules loaded and telling the server what file types to parse.) I know this may be an extremely easy fix, but then in that case, hopefully you wouldn't mind helping me out a little :). If it turns out that this is MUCH more complicated than I expect, then feel free to let me know that, so I don't waste me time running in circles. I appreciate any help/assistance that you can provide, Thanks, Jake EDIT: Wrong Apache version. In response to the comments/closing of this thread: My question: "How exactly do I install the PHP module on the apache server? and is this even possible? and is this even recommended?" ^ In case I wasn't clear enough already To Clarify: I understand the basics of PHP, I just have trouble with INSTALLING PHP on the apache server. (I have used PHP before, but never successfully on apache (so far...)) For my script I wrote something similar to this already (using fopen() and a few other commands): <?php fopen("notes.txt", "r"); file_put_contents("notes.txt",teststring1); ?> I have used javascript for this task before also (although I prefer using PHP and server-side languages): <script language="javascript"> function WriteToFile(){ var fso = new ActiveXObject("Scripting.FileSystemObject"); var s = fso.CreateTextFile("C:\\NewFile.txt", true); var text=document.getElementById("TextArea1").innerText; s.WriteLine(text); s.WriteLine('***********************'); s.Close(); } </script>

• WCF endpoint exception

  - by Lijo

  Hi Team, I am just trying with various WCF(in .Net 3.0) scenarios. I am using self hosting. I am getting an exception as "Service 'MyServiceLibrary.NameDecorator' has zero application (non-infrastructure) endpoints. This might be because no configuration file was found for your application, or because no service element matching the service name could be found in the configuration file, or because no endpoints were defined in the service element." I have a config file as follows (which has an endpoint) <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <services> <service name="Lijo.Samples.NameDecorator" behaviorConfiguration="WeatherServiceBehavior"> <host> <baseAddresses> <add baseAddress="http://localhost:8010/ServiceModelSamples/FreeServiceWorld"/> </baseAddresses> </host> <endpoint address="" binding="wsHttpBinding" contract="Lijo.Samples.IElementaryService" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="WeatherServiceBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="False"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> </configuration> And a Host as using System.ServiceModel; using System.ServiceModel.Dispatcher; using System.ServiceModel.Channels; using System.ServiceModel.Description; using System.Runtime.Serialization; namespace MySelfHostConsoleApp { class Program { static void Main(string[] args) { System.ServiceModel.ServiceHost myHost = new ServiceHost(typeof(MyServiceLibrary.NameDecorator)); myHost.Open(); Console.ReadLine(); } } } My Service is as follows using System.ServiceModel; using System.Runtime.Serialization; namespace MyServiceLibrary { [ServiceContract(Namespace = "http://Lijo.Samples")] public interface IElementaryService { [OperationContract] CompanyLogo GetLogo(); } public class NameDecorator : IElementaryService { public CompanyLogo GetLogo() { CircleType cirlce = new CircleType(); CompanyLogo logo = new CompanyLogo(cirlce); return logo; } } [DataContract] public abstract class IShape { public abstract string SelfExplain(); } [DataContract(Name = "Circle")] public class CircleType : IShape { public override string SelfExplain() { return "I am a Circle"; } } [DataContract(Name = "Triangle")] public class TriangleType : IShape { public override string SelfExplain() { return "I am a Triangle"; } } [DataContract] [KnownType(typeof(CircleType))] [KnownType(typeof(TriangleType))] public class CompanyLogo { private IShape m_shapeOfLogo; [DataMember] public IShape ShapeOfLogo { get { return m_shapeOfLogo; } set { m_shapeOfLogo = value; } } public CompanyLogo(IShape shape) { m_shapeOfLogo = shape; } } } Could you please help me to understand what I am missing here?

• Email sent from server with rDNS & SPF being blocked by Hotmail

  - by Canadaka

  I have been unable to send email to users on hotmail or other Microsoft email servers for some time. Its been a major headache trying to find out why and how to fix the issue. The emails being sent that are blocked from my domain canadaka.net. I use Google Aps to host my regular email serverice for my @canadaka.net email addresses. I can sent email from my desktop or gmail to a hotmail without any problem. But any email sent from my server on behalf of canadaka.net is blocked, not even arriving in the junk email. The IP that the emails are being sent from is the same IP that my site is hosted on: 66.199.162.177 This IP is new to me since August 2010, I had a different IP for the previous 3-4 years. This IP is not on any credible spam lists http://www.anti-abuse.org/multi-rbl-check-results/?host=66.199.162.177 The one list spamcannibal.org my IP is listed on seems to be out of my control, says "no reverse DNS, MX host should have rDNS - RFC1912 2.1". But since I use Google for my email hosting, I don't have control over setting up RDNS for all the MX records. I do have Reverse DNS setup for my IP though, it resolves to "mail.canadaka.net". I have signed up for SNDS and was approved. My ip says "All of the specified IPs have normal status." Sender Score: 100 https://www.senderscore.org/lookup.php?lookup=66.199.162.177&ipLookup.x=55&ipLookup.y=14 My Mcafee threat level seems fine I have a TXT SPF record setup, I am currently using xname.org as my DNS, and they don't have a field for SPF, but their FAQ says to add the SPF info as a TXT entry. v=spf1 a include:_spf.google.com ~all Some "SPF checking" tools ive used detect that my domain has a valid SPF, but others don't. Like Microsoft's SPF wizard, i think this is because its specifically looking for an SPF record and not in the TXT. "No SPF Record Found. A and MX Records Available". From my home I can run "nslookup -type=TXT canadaka.net" and it returns: Server: google-public-dns-a.google.com Address: 8.8.8.8 Non-authoritative answer: canadaka.net text = "v=spf1 a include:_spf.google.com ~all" One strange thing I found is i'm unable to ping hotmail.com or msn.com or do a "telnet mail.hotmail.com 25". I am able to ping gmail.com and many other domains I tried. I tried changing my DNS servers to Google's Public DNS and did a ipconfig /flushdns but that had no effect. I am however able to connect with telnet to mx1.hotmail.com This is what the email headers look like when I send to a Google email server and I receive the email with no troubles. You can see that SPF is passing.

UPDATE 2 I used Telnet to send a test message to port25.com, seems my SPF is not being detected. Result: neutral (SPF-Result: None) canadaka.net. SPF (no records) canadaka.net. TXT (no records) I do have a TXT record, its been there for years, I did change it a week ago. Other sites that allow you to check your SPF detect it, but some others like Microsofts Wizard doesn't. This iw what my SPF record in my xname.org DNS file looks like: canadaka.net. 86400 IN TXT "v=spf1 a include:_spf.google.com ~all" I did have a nameserver as my 4th option that doens't have the TXT records since it doens't support it. So I removed it from the list and instead added wtfdns.com as my 4th adn 5th nameservers, which does support TXT.

• Receicing POST data in ASP.NET

  - by grast

  Hi, I want to use ASP for code generation in a C# desktop application. To achieve this, I set up a simple host (derived from System.MarshalByRefObject) that processes a System.Web.Hosting.SimpleWorkerRequest via HttpRuntime.ProcessRequest. This processes the ASPX script specified by the incoming request (using System.Net.HttpListener to wait for requests). The client-part is represented by a System.ComponentModel.BackgroundWorker that builds the System.Net.HttpWebRequest and receives the response from the server. A simplified version of my client-part-code looks like this: private void SendRequest(object sender, DoWorkEventArgs e) { // create request with GET parameter var uri = "http://localhost:9876/test.aspx?getTest=321"; var request = (HttpWebRequest)WebRequest.Create(uri); // append POST parameter request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; var postData = Encoding.Default.GetBytes("postTest=654"); var postDataStream = request.GetRequestStream(); postDataStream.Write(postData, 0, postData.Length); // send request, wait for response and store/print content using (var response = (HttpWebResponse)request.GetResponse()) { using (var reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8)) { _processsedContent = reader.ReadToEnd(); Debug.Print(_processsedContent); } } } My server-part-code looks like this (without exception-handling etc.): public void ProcessRequests() { // HttpListener at http://localhost:9876/ var listener = SetupListener(); // SimpleHost created by ApplicationHost.CreateApplicationHost var host = SetupHost(); while (_running) { var context = listener.GetContext(); using (var writer = new StreamWriter(context.Response.OutputStream)) { // process ASP script and send response back to client host.ProcessRequest(GetPage(context), GetQuery(context), writer); } context.Response.Close(); } } So far all this works fine as long as I just use GET parameters. But when it comes to receiving POST data in my ASPX script I run into trouble. For testing I use the following script: // GET parameters are working: var getTest = Request.QueryString["getTest"]; Response.Write("getTest: " + getTest); // prints "getTest: 321" // don't know how to access POST parameters: var postTest1 = Request.Form["postTest"]; // Request.Form is empty?! Response.Write("postTest1: " + postTest1); // so this prints "postTest1: " var postTest2 = Request.Params["postTest"]; // Request.Params is empty?! Response.Write("postTest2: " + postTest2); // so this prints "postTest2: " It seems that the System.Web.HttpRequest object I'm dealing with in ASP does not contain any information about my POST parameter "postTest". I inspected it in debug mode and none of the members did contain neither the parameter-name "postTest" nor the parameter-value "654". I also tried the BinaryRead method of Request, but unfortunately it is empty. This corresponds to Request.InputStream==null and Request.ContentLength==0. And to make things really confusing the Request.HttpMethod member is set to "GET"?! To isolate the problem I tested the code by using a PHP script instead of the ASPX script. This is very simple: print_r($_GET); // prints all GET variables print_r($_POST); // prints all POST variables And the result is: Array ( [getTest] = 321 ) Array ( [postTest] = 654 ) So with the PHP script it works, I can access the POST data. Why does the ASPX script don't? What am I doing wrong? Is there a special accessor or method in the Response object? Can anyone give a hint or even know how to solve this? Thanks in advance.

• Issue with Silverlight interop with JBoss WebService

  - by Hadi Eskandari

  I have a simple JAXWS webservice deployed in JBoss. It runs fine with a java client but I'm trying to connect using a Silverlight 3.0 application. I've changed the webservice to use Soap 1.1: @BindingType(value = "http://schemas.xmlsoap.org/wsdl/soap/http") public class UserSessionBean implements UserSessionRemote { ... } I'm using BasicHttpBinding on the Silverlight client. There are two issues: 1- When I connect from VisualStudio (2008 and 2010) to create the webservice proxies, the following exception is thrown, but the proxy is generated successfully. This also happens when I try to update the existing web service reference (but it also updates fine). com.sun.xml.ws.server.UnsupportedMediaException: Unsupported Content-Type: application/soap+xml; charset=utf-8 Supported ones are: [text/xml] at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:291) at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:128) at com.sun.xml.ws.encoding.SOAPBindingCodec.decode(SOAPBindingCodec.java:287) at com.sun.xml.ws.transport.http.HttpAdapter.decodePacket(HttpAdapter.java:276) at com.sun.xml.ws.transport.http.HttpAdapter.access$500(HttpAdapter.java:93) at com.sun.xml.ws.transport.http.HttpAdapter$HttpToolkit.handle(HttpAdapter.java:432) at com.sun.xml.ws.transport.http.HttpAdapter.handle(HttpAdapter.java:244) at com.sun.xml.ws.transport.http.servlet.ServletAdapter.handle(ServletAdapter.java:135) at org.jboss.wsf.stack.metro.RequestHandlerImpl.doPost(RequestHandlerImpl.java:225) at org.jboss.wsf.stack.metro.RequestHandlerImpl.handleHttpRequest(RequestHandlerImpl.java:82) at org.jboss.wsf.common.servlet.AbstractEndpointServlet.service(AbstractEndpointServlet.java:85) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:182) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) at java.lang.Thread.run(Thread.java:619) 2- When I use the proxy to fetch some data from the webservice (even methods with primitive types), I get the following error on Silverlight client: "An error occurred while trying to make a request to URI 'http://localhost:9090/admintool/UserSessionEJB'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details." Setting a breakpoint on my java code, I can see that it is not hit when I run the silverlight client, so it is probably a cross domain issue, but I'm not sure how to handle it (I've already created a crossdomain.xml file and put it beside my HTML page hosting the silverlight client). I appreciate any help!

• 500 Internal Server Error with PHP application

  - by James

  I have written a PHP application using Windows and XAMPP. I've been trying to run it on Ubuntu 10.10 with Lighttpd 1.4.26. Parts of the application work fine, but whenever I try to log in, I get a 500 - Internal Server Error page.

• Django ImageField issue with JPEG's

  - by Kieran Lynn

  I am having a major issue with PIL (Python Image Library) in Django and have jumpped through a lot of hoops and have thus far not been able to figure out what the root of the issue is. The problem essentially breaks down to not being able to upload JPEG images through the ImageField in the Django admin. But the issue is not as simple as installing libjpeg. First, I installed PIL (through Buildout) and realized once it was installed that I had not installed libjpeg because JPEG support was not available. Having not setup the server myself, I just assumed that it was not installed and I compiled libjpeg 8 from the source. This ended up in my /usr/local/lib/ directory. I cleared out my Buildout files and rebuilt everything. This time when PIL compiled I had JPEG support. But I went to the Django Admin and tried to upload a JPEG though an ImageField with no luck. I got the "Upload a valid image. The file you uploaded was either not an image or a corrupted image" error. Just as a test I opened up a the Djano shell and ran the following: > import Image > i = Image.open( "/absolute_path/file.jpg" ) > print i <JpegImagePlugin.JpegImageFile image mode=RGB size=940x375 at 0x7F908C529BD8> This runs with no errors and shows that PIL is able to open JPEG's. After doing some reading, I come across this thread: Is it possible to control which libraries apache uses? Looks like PHP also uses libjpeg and is loading before Django, and therefor loading libjpeg 6.2 before. This is show when using lsof: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME apache2 2561 www-data mem REG 202,1 146032 639276 /usr/lib/libjpeg.so.62.0.0 So my thought is that I should be using libjpeg 6.2. So I removed libjpeg located in my /usr/local/lib directory. After rereading the PIL installation instructions, I realized that I might not have the dev/header files for libjpeg that PIL needs. So I also uninstalled libjpeg using the aptitude uninstaller (sudo aptitude remove libjpeg62). Then to ensure that I got the header files that PIL needed I installed libjpeg using aptitude: (sudo aptget install libjpeg62-dev). From here I cleaned out my Buildout directory, and reran Buildout, which in turn reinstalled PIL. Once again, I have JPEG support, now using the libjpeg62. So I go to test in the Django Admin. Still no JPEG support. So I wanted to test JPEG support in general and see if the exception was not handled, what kind of error it would throw. So in my homepage view I added the following code to open a JPEG image: import Image i = Image.open( "/absolute_path/file.jpg" ) v = i.verify() Then I pass i to the HTML view just to easily see the output. I deploy these changes to the server and restart. I am surprised not to see an error and get the following output: {{ i }} - <JpegImagePlugin.JpegImageFile image mode=RGB size=940x375 at 0x7F908C529BD8> {{ v }} - None So at this point I am really confused: Why can I successfully open a JPEG while the admin cannot? Am I missing something, is this not an issue with libjpeg? If not an issue with libjpeg, why can I upload a PNG with no issues? Any help would be much appreciated, I have been on this for 2 days debugging with no luck. Setup: 1. Rackspace Cloud Server 2. Ubuntu 10.04 3. Django 1.2.3 (Installed though Buildout) 4. PIL 1.1.7 (Installed though Buildout) 5. libjpeg 6.2 (installed through aptitude (sudo aptget install libjpeg62-dev)

• PHP framework question

  - by iconiK

  I'm currently working on a browser-based MMO and have chosen the LAMP stack because of the extremely low cost to start with in production (versus Windows + IIS + ASP.NET/C# + SQL Server, even though I have MSDN Universal). However I will need a PHP framework for this as it's no easy task. I am not restricted by anything other than the ability to run on Linux, as I will use a dedicated cloud hosting solution (and a VMWare image for development) and can configure it as needed. In no specific order: It has to be easily scalable; this is crucial. If the game becomes a steady success it will eventually outgrow the server beyond what the host provides and would have to be moved to several load-balanced servers. It is crucial that this can be done with minimum effort. I do know this might require following strict conventions, so if you know of any for your suggested framework please explain what would be needed. It has to provide modules for all the core tasks: authentication, ACL, database access, MVC, and so on. One or two missing modules are fine, as long as they can easily be written and integrated. It should support internationalization. I think there is no excuse for any web framework not to provide means of translating the application and switching between languages without a lot of effort from the programmer. Must have very good community support and preferably commercial support as well. Yes, I do know QCodo/QCubed is so nice, but it is not mature enough for this task. Smooth AJAX support is required. Whether the framework comes with AJAX-capable widgets or has an easy way of adding AJAX is not relevant, as long as AJAX is easily doable. I plan to use jQuery + Dojo or one of them alone - not exactly sure. Auto-magically doing stuff when it improves readability and relieves a lot of effort would be especially nice if it is generally reliable and does not interfere with other requirements. This seems to be the case of CakePHP. I have read a lot of comparisons and I know it's a really hot debate. The general answer is "try and see for yourself what suits you". However, I can't say it is easy for this task and I'm calling for your experience with building applications with similar requirements. So far I'm tied up between Zend and CakePHP by the general criteria, however, all well-known frameworks offer the same functionality in some way or another with different approaches each with it's own advantages and disadvantages. Edits: I am kinda new to MVC, however, I am willing to learn it and I don't care if a framework is easier for those new to MVC. I have lots of time to learn MVC and any other architectures (or whatever they're called) you recommend. I will use Zend as a utility "framework", even though it's just a collection of libraries (some good ones though, as I have been told). Current PHP contenders are: CakePHP, Kohana, Zend alone.

• Server Memory with Magento

  - by Mohamed Elgharabawy

  I have a cloud server with the following specifications: 2vCPUs 4G RAM 160GB Disk Space Network 400Mb/s System Image: Ubuntu 12.04 LTS I am only running Magento CE 1.7.0.2 on this server.

• WCF .svc Accessible Over HTTP But Accessing WSDL Causes "Connection Was Reset"

  - by Wolfwyrd

  I have a WCF service which is hosted on IIS6 on a Win2003 SP2 machine. The WCF service is hosting correctly and is visible over HTTP giving the usual "To test this service, you will need to create a client and use it to call the service" message. However accessing the .svc?WSDL link causes the connection to be reset. The server itself is returning a 200 in the logs for the WSDL request, an example of which is shown here, the first call gets a connection reset, the second is a successful call for the .svc file. 2010-04-09 11:00:21 W3SVC6 MACHINENAME 10.79.42.115 GET /IntegrationService.svc wsdl 80 - 10.75.33.71 HTTP/1.1 Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+2.0.50727;+.NET+CLR+1.1.4322;+.NET+CLR+1.0.3705;+InfoPath.1;+.NET+CLR+3.0.04506.30;+MS-RTC+LM+8;+.NET+CLR+3.0.4506.2152;+.NET+CLR+3.5.30729;) - - devsitename.mydevdomain.com 200 0 0 0 696 3827 2010-04-09 11:04:10 W3SVC6 MACHINENAME 10.79.42.115 GET /IntegrationService.svc - 80 - 10.75.33.71 HTTP/1.1 Mozilla/5.0+(Windows;+U;+Windows+NT+5.1;+en-GB;+rv:1.9.1.9)+Gecko/20100315+Firefox/3.5.9+(.NET+CLR+3.5.30729) - - devsitename.mydevdomain.com 200 0 0 3144 457 265 My Web.Config looks like: <system.serviceModel> <serviceHostingEnvironment > <baseAddressPrefixFilters> <add prefix="http://devsitename.mydevdomain.com" /> </baseAddressPrefixFilters> </serviceHostingEnvironment> <behaviors> <serviceBehaviors> <behavior name="My.Service.IntegrationServiceBehavior"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> </serviceBehaviors> </behaviors> <services> <service behaviorConfiguration="My.Service.IntegrationServiceBehavior" name="My.Service.IntegrationService"> <endpoint address="" binding="wsHttpBinding" contract="My.Service.Interfaces.IIntegrationService" bindingConfiguration="NoSecurityConfig" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <bindings> <wsHttpBinding> <binding name="NoSecurityConfig"> <security mode="None" /> </binding> </wsHttpBinding> </bindings> </system.serviceModel> I'm pretty much stumped by this one. It works fine through the local dev server in VS2008 but fails after deployment. For further information, the targeted machine does not have a firewall (it's on the internal network) and the logs show the site thinks it's fine with 200 OK responses. I've also tried updating the endpoint with the full URL to my service however it still makes no difference. I have looked into some of the other options - creating a separate WSDL manually and exposing it through the metadata properties (really don't want to do that due to the maintenance issues). If anyone can offer any thoughts on this or any other workarounds it would be greatly appreciated.

• Core Plot never stops asking for data, hangs device

  - by Ben Collins

  I'm trying to set up a core plot that looks somewhat like the AAPLot example on the core-plot wiki. I have set up my plot like this: - (void)initGraph:(CPXYGraph*)graph forDays:(NSUInteger)numDays { self.cplhView.hostedLayer = graph; graph.paddingLeft = 30.0; graph.paddingTop = 20.0; graph.paddingRight = 30.0; graph.paddingBottom = 20.0; CPXYPlotSpace *plotSpace = (CPXYPlotSpace*)graph.defaultPlotSpace; plotSpace.xRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(0) length:CPDecimalFromFloat(numDays)]; plotSpace.yRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(0) length:CPDecimalFromFloat(1)]; CPLineStyle *lineStyle = [CPLineStyle lineStyle]; lineStyle.lineColor = [CPColor blackColor]; lineStyle.lineWidth = 2.0f; // Axes NSLog(@"Setting up axes"); CPXYAxisSet *xyAxisSet = (id)graph.axisSet; CPXYAxis *xAxis = xyAxisSet.xAxis; // xAxis.majorIntervalLength = CPDecimalFromFloat(7); // xAxis.minorTicksPerInterval = 7; CPXYAxis *yAxis = xyAxisSet.yAxis; // yAxis.majorIntervalLength = CPDecimalFromFloat(0.1); // Line plot with gradient fill NSLog(@"Setting up line plot"); CPScatterPlot *dataSourceLinePlot = [[[CPScatterPlot alloc] initWithFrame:graph.bounds] autorelease]; dataSourceLinePlot.identifier = @"Data Source Plot"; dataSourceLinePlot.dataLineStyle = nil; dataSourceLinePlot.dataSource = self; [graph addPlot:dataSourceLinePlot]; CPColor *areaColor = [CPColor colorWithComponentRed:1.0 green:1.0 blue:1.0 alpha:0.6]; CPGradient *areaGradient = [CPGradient gradientWithBeginningColor:areaColor endingColor:[CPColor clearColor]]; areaGradient.angle = -90.0f; CPFill *areaGradientFill = [CPFill fillWithGradient:areaGradient]; dataSourceLinePlot.areaFill = areaGradientFill; dataSourceLinePlot.areaBaseValue = CPDecimalFromString(@"320.0"); // OHLC plot NSLog(@"OHLC Plot"); CPLineStyle *whiteLineStyle = [CPLineStyle lineStyle]; whiteLineStyle.lineColor = [CPColor whiteColor]; whiteLineStyle.lineWidth = 1.0f; CPTradingRangePlot *ohlcPlot = [[[CPTradingRangePlot alloc] initWithFrame:graph.bounds] autorelease]; ohlcPlot.identifier = @"OHLC"; ohlcPlot.lineStyle = whiteLineStyle; ohlcPlot.stickLength = 2.0f; ohlcPlot.plotStyle = CPTradingRangePlotStyleOHLC; ohlcPlot.dataSource = self; NSLog(@"Data source set, adding plot"); [graph addPlot:ohlcPlot]; } And my delegate methods like this: #pragma mark - #pragma mark CPPlotdataSource Methods - (NSUInteger)numberOfRecordsForPlot:(CPPlot *)plot { NSUInteger maxCount = 0; NSLog(@"Getting number of records."); if (self.data1 && [self.data1 count] > maxCount) { maxCount = [self.data1 count]; } if (self.data2 && [self.data2 count] > maxCount) { maxCount = [self.data2 count]; } if (self.data3 && [self.data3 count] > maxCount) { maxCount = [self.data3 count]; } NSLog(@"%u records", maxCount); return maxCount; } - (NSNumber *)numberForPlot:(CPPlot *)plot field:(NSUInteger)fieldEnum recordIndex:(NSUInteger)index { NSLog(@"Getting record @ idx %u", index); return [NSNumber numberWithInt:index]; } All the code above is in the view controller for the view hosting the plot, and when initGraph is called, numDays is 30. I realize of course that this plot, if it even worked, would look nothing like the AAPLot example. The problem I'm having is that the view is never shown. It finished loading because viewDidLoad is the method that calls initGraph above, and the NSLog statements indicate that initGraph finishes. What's strange is that I return a value of 54 from numberOfRecordsForPlot, but the plot asks for more than 54 data points. in fact, it never stops asking. The NSLog statement in numberForPlot:field:recordIndex prints forever, going from 0 to 54 and then looping back around and continuing. What's going on? Why won't the plot stop asking for data and draw itself?

• Clickonce installation fails after addition of WCF service project

  - by Ant

  So I have a winform solution, deployed via clickonce. Eveything worked fine until i added a WCF project. (see error in parsing the manifest file at end of post) Now I notice that MSBuild compiles the service into a _PublishedWebsites dir. I don't know what the need for this is, but I am suspecting this is the cause of the problem. This wcf project references some other projects within the solution. I am actually hosting the wcf service within the application so I don't really need MSBuild to do all this for me.

• How to reduce Entity Framework 4 query compile time?

  - by Rup

  Summary: We're having problems with EF4 query compilation times of 12+ seconds. Cached queries will only get us so far; are there any ways we can actually reduce the compilation time? Is there anything we might be doing wrong we can look for? Thanks! We have an EF4 model which is exposed over the WCF services. For each of our entity types we expose a method to fetch and return the whole entity for display / edit including a number of referenced child objects. For one particular entity we have to .Include() 31 tables / sub-tables to return all relevant data. Unfortunately this makes the EF query compilation prohibitively slow: it takes 12-15 seconds to compile and builds a 7,800-line, 300K query. This is the back-end of a web UI which will need to be snappier than that. Is there anything we can do to improve this? We can CompiledQuery.Compile this - that doesn't do any work until first use and so helps the second and subsequent executions but our customer is nervous that the first usage shouldn't be slow either. Similarly if the IIS app pool hosting the web service gets recycled we'll lose the cached plan, although we can increase lifetimes to minimise this. Also I can't see a way to precompile this ahead of time and / or to serialise out the EF compiled query cache (short of reflection tricks). The CompiledQuery object only contains a GUID reference into the cache so it's the cache we really care about. (Writing this out it occurs to me I can kick off something in the background from app_startup to execute all queries to get them compiled - is that safe?) However even if we do solve that problem, we build up our search queries dynamically with LINQ-to-Entities clauses based on which parameters we're searching on: I don't think the SQL generator does a good enough job that we can move all that logic into the SQL layer so I don't think we can pre-compile our search queries. This is less serious because the search data results use fewer tables and so it's only 3-4 seconds compile not 12-15 but the customer thinks that still won't really be acceptable to end-users. So we really need to reduce the query compilation time somehow. Any ideas? Profiling points to ELinqQueryState.GetExecutionPlan as the place to start and I have attempted to step into that but without the real .NET 4 source available I couldn't get very far, and the source generated by Reflector won't let me step into some functions or set breakpoints in them. The project was upgraded from .NET 3.5 so I have tried regenerating the EDMX from scratch in EF4 in case there was something wrong with it but that didn't help. I have tried the EFProf utility advertised here but it doesn't look like it would help with this. My large query crashes its data collector anyway. I have run the generated query through SQL performance tuning and it already has 100% index usage. I can't see anything wrong with the database that would cause the query generator problems. Is there something O(n^2) in the execution plan compiler - is breaking this down into blocks of separate data loads rather than all 32 tables at once likely to help? Setting EF to lazy-load didn't help. I've bought the pre-release O'Reilly Julie Lerman EF4 book but I can't find anything in there to help beyond 'compile your queries'. I don't understand why it's taking 12-15 seconds to generate a single select across 32 tables so I'm optimistic there's some scope for improvement! Thanks for any suggestions! We're running against SQL Server 2008 in case that matters and XP / 7 / server 2008 R2 using RTM VS2010.

• WCF via SSL connectivity problems

  - by Brett Widmeier

  Hello, I am hosting a WCF service from inside a Windows service using WAS. When I set the service to listen on 127.0.0.1, I have connectivity from my local machine as well as from my network. However, when I set it to listen on my outbound interface port 443, I can no longer even see the wsdl by connecting with a browser. Strangely, I can connect to the service by using telnet. The cert I am using was generated for my interface by a CA, and I have successfully used this exact cert with this service before. When checking the application log, I see that the service starts without error and is listening on the correct interface. From this information, it seems to me that the config file is in a valid state, but somehow misconfigured for what I want. I have, however, previously deployed this same setup on other sites using this config file. In case it is helpful, below is my config file. Any thoughts? <!--<system.diagnostics> <sources> <source name="System.ServiceModel" switchValue="Warning, ActivityTracing" propagateActivity="true"> <listeners> <add type="System.Diagnostics.DefaultTraceListener" name="Default"> <filter type="" /> </add> <add name="ServiceModelTraceListener"> <filter type="" /> </add> </listeners> </source> </sources> <sharedListeners> <add initializeData="app_tracelog.svclog" type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" name="ServiceModelTraceListener" traceOutputOptions="Timestamp"> <filter type="" /> </add> </sharedListeners> </system.diagnostics>--> <appSettings/> <connectionStrings/> <system.serviceModel> <!--<diagnostics> <messageLogging logEntireMessage="true" logMalformedMessages="true" logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" maxMessagesToLog ="1000" maxSizeOfMessageToLog="524288"/> </diagnostics>--> <bindings> <basicHttpBinding> <binding name="basicHttps"> <security mode="Transport"> <transport clientCredentialType="None"/> <message /> </security> </binding> </basicHttpBinding> </bindings> <services> <service behaviorConfiguration="ServiceBehavior" name="<fully qualified name of service>"> <endpoint address="" binding="basicHttpBinding" name="OrdersSoap" contract="<fully qualified name of contract>" bindingNamespace="http://emr.orders.com/WebServices" bindingConfiguration="basicHttps" /> <endpoint binding="mexHttpsBinding" address="mex" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="https://<external IP>/<name of service>>/" /> </baseAddresses> </host> </service> </services> <behaviors> <serviceBehaviors> <behavior name="ServiceBehavior"> <serviceMetadata httpsGetEnabled="False"/> <serviceDebug includeExceptionDetailInFaults="True" /> <dataContractSerializer maxItemsInObjectGraph="2147483646"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel>

• WinMo > ASMX WebException - how to get details?

  - by eidylon

  Okay, we've got an application which consists of a website hosting several ASMX webservices, and a handheld application running on WinMo 6.1 which calls the webservices. Been developing in the office, everything works perfect. Now we've gone to install it at the client's and we got all the servers set up and the handhelds installed. However the handhelds are now no longer able to connect to the webservice. I added in extra code in my error handler to specifically trap WebException exceptions and handle them differently in the logging to put out extra information (.Status and .Response). I am getting out the status, which is returning a [7], or ProtocolError. However when I try to read out the ResponseStream (using WebException.Response.GetResponseStream), it is returning a stream with CanRead set to False, and I thus am unable to get any further details of what is going wrong. So I guess there are two things I am asking for help with... a) Any help with trying to get more information out of the WebException? b) What could be causing a ProtocolError exception? Things get extra complicated by the fact that the client has a full-blown log-in-enabled proxy setup going on-site. This was stopping all access to the website initially, even from a browser. So we entered in the login details in the network connection for HTTP on the WinMo device. Now it can get to websites fine. In fact, I can even pull up the webservice fine and call the methods from the browser (PocketIE). So I know the device is able to see the webservices okay via HTTP. But when trying to call them from the .NET app, it throws ProtocolError [7]. Here is my code which is logging the exception and failing to read out the Response from the WebException. Public Sub LogEx(ByVal ex As Exception) Try Dim fn As String = Path.Combine(ini.CorePath, "error.log") Dim t = File.AppendText(fn) t.AutoFlush = True t.WriteLine(<s>===== <%= Format(GetDateTime(), "MM/dd/yyyy HH:mm:ss") %> =====<%= vbCrLf %><%= ex.Message %></s>.Value) t.WriteLine() t.WriteLine(ex.ToString) t.WriteLine() If TypeOf ex Is WebException Then With CType(ex, WebException) t.WriteLine("STATUS: " & .Status.ToString & " (" & Val(.Status) & ")") t.WriteLine("RESPONSE:" & vbCrLf & StreamToString(.Response.GetResponseStream())) End With End If t.WriteLine("=".Repeat(50)) t.WriteLine() t.Close() Catch ix As Exception : Alert(ix) : End Try End Sub Private Function StreamToString(ByVal s As IO.Stream) As String If s Is Nothing Then Return "No response found." // THIS IS THE CASE BEING EXECUTED If Not s.CanRead Then Return "Unreadable response found." Dim rv As String = String.Empty, bytes As Long, buffer(4096) As Byte Using mem As New MemoryStream() Do While True bytes = s.Read(buffer, 0, buffer.Length) mem.Write(buffer, 0, bytes) If bytes = 0 Then Exit Do Loop mem.Position = 0 ReDim buffer(mem.Length) mem.Read(buffer, 0, mem.Length) mem.Seek(0, SeekOrigin.Begin) rv = New StreamReader(mem).ReadToEnd() mem.Close() End Using Return rv.NullOf("Empty response found.") End Function Thanks in advance!

• Receiving POST data in ASP.NET

  - by grast

  Hi, I want to use ASP for code generation in a C# desktop application. To achieve this, I set up a simple host (derived from System.MarshalByRefObject) that processes a System.Web.Hosting.SimpleWorkerRequest via HttpRuntime.ProcessRequest. This processes the ASPX script specified by the incoming request (using System.Net.HttpListener to wait for requests). The client-part is represented by a System.ComponentModel.BackgroundWorker that builds the System.Net.HttpWebRequest and receives the response from the server. A simplified version of my client-part-code looks like this: private void SendRequest(object sender, DoWorkEventArgs e) { // create request with GET parameter var uri = "http://localhost:9876/test.aspx?getTest=321"; var request = (HttpWebRequest)WebRequest.Create(uri); // append POST parameter request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; var postData = Encoding.Default.GetBytes("postTest=654"); var postDataStream = request.GetRequestStream(); postDataStream.Write(postData, 0, postData.Length); // send request, wait for response and store/print content using (var response = (HttpWebResponse)request.GetResponse()) { using (var reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8)) { _processsedContent = reader.ReadToEnd(); Debug.Print(_processsedContent); } } } My server-part-code looks like this (without exception-handling etc.): public void ProcessRequests() { // HttpListener at http://localhost:9876/ var listener = SetupListener(); // SimpleHost created by ApplicationHost.CreateApplicationHost var host = SetupHost(); while (_running) { var context = listener.GetContext(); using (var writer = new StreamWriter(context.Response.OutputStream)) { // process ASP script and send response back to client host.ProcessRequest(GetPage(context), GetQuery(context), writer); } context.Response.Close(); } } So far all this works fine as long as I just use GET parameters. But when it comes to receiving POST data in my ASPX script I run into trouble. For testing I use the following script: // GET parameters are working: var getTest = Request.QueryString["getTest"]; Response.Write("getTest: " + getTest); // prints "getTest: 321" // don't know how to access POST parameters: var postTest1 = Request.Form["postTest"]; // Request.Form is empty?! Response.Write("postTest1: " + postTest1); // so this prints "postTest1: " var postTest2 = Request.Params["postTest"]; // Request.Params is empty?! Response.Write("postTest2: " + postTest2); // so this prints "postTest2: " It seems that the System.Web.HttpRequest object I'm dealing with in ASP does not contain any information about my POST parameter "postTest". I inspected it in debug mode and none of the members did contain neither the parameter-name "postTest" nor the parameter-value "654". I also tried the BinaryRead method of Request, but unfortunately it is empty. This corresponds to Request.InputStream==null and Request.ContentLength==0. And to make things really confusing the Request.HttpMethod member is set to "GET"?! To isolate the problem I tested the code by using a PHP script instead of the ASPX script. This is very simple: print_r($_GET); // prints all GET variables print_r($_POST); // prints all POST variables And the result is: Array ( [getTest] = 321 ) Array ( [postTest] = 654 ) So with the PHP script it works, I can access the POST data. Why does the ASPX script don't? What am I doing wrong? Is there a special accessor or method in the Response object? Can anyone give a hint or even know how to solve this? Thanks in advance.

• How do you stop scripters from slamming your website hundreds of times a second?

  - by davebug

  [update] I've accepted an answer, as lc deserves the bounty due to the well thought-out answer, but sadly, I believe we're stuck with our original worst case scenario: CAPTCHA everyone on purchase attempts of the crap. Short explanation: caching / web farms make it impossible for us to actually track hits, and any workaround (sending a non-cached web-beacon, writing to a unified table, etc.) slows the site down worse than the bots would. There is likely some pricey bit of hardware from Cisco or the like that can help at a high level, but it's hard to justify the cost if CAPTCHAing everyone is an alternative. I'll attempt to do a more full explanation in here later, as well as cleaning this up for future searchers (though others are welcome to try, as it's community wiki). I've added bounty to this question and attempted to explain why the current answers don't fit our needs. First, though, thanks to all of you who have thought about this, it's amazing to have this collective intelligence to help work through seemingly impossible problems. I'll be a little more clear than I was before: This is about the bag o' crap sales on woot.com. I'm the president of Woot Workshop, the subsidiary of Woot that does the design, writes the product descriptions, podcasts, blog posts, and moderates the forums. I work in the css/html world and am only barely familiar with the rest of the developer world. I work closely with the developers and have talked through all of the answers here (and many other ideas we've had). Usability of the site is a massive part of my job, and making the site exciting and fun is most of the rest of it. That's where the three goals below derive. CAPTCHA harms usability, and bots steal the fun and excitement out of our crap sales. To set up the scenario a little more, bots are slamming our front page tens of times a second screenscraping (and/or scanning our rss) for the Random Crap sale. The moment they see that, it triggers a second stage of the program that logs in, clicks I want One, fills out the form, and buys the crap. In current (2/6/2009) order of votes: lc: On stackoverflow and other sites that use this method, they're almost always dealing with authenticated (logged in) users, because the task being attempted requires that. On Woot, anonymous (non-logged) users can view our home page. In other words, the slamming bots can be non-authenticated (and essentially non-trackable except by IP address). So we're back to scanning for IPs, which a) is fairly useless in this age of cloud networking and spambot zombies and b) catches too many innocents given the number of businesses that come from one IP address (not to mention the issues with non-static IP ISPs and potential performance hits to trying to track this). Oh, and having people call us would be the worst possible scenario. Can we have them call you? BradC Ned Batchelder's methods look pretty cool, but they're pretty firmly designed to defeat bots built for a network of sites. Our problem is bots are built specifically to defeat our site. Some of these methods could likely work for a short time until the scripters evolved their bots to ignore the honeypot, screenscrape for nearby label names instead of form ids, and use a javascript-capable browser control. lc again "Unless, of course, the hype is part of you

• Trac FastCGI + Python on dreamhost leaves zombie python running

  - by Katsuke

  Hello there, Recently I installed trac in one of my dreamhost domains. I followed the instructions of http://trac.mlalonde.net/wiki/CreamyTrac and everything worked perfectly. At least i thought that was the case. After a few days, i started to notice that i was getting random 500 pages. I quickly checked the error log, and found a bunch of: [Fri Apr 16 14:35:34 2010] [error] [client *.*.*.*] Premature end of script headers: dispatch.fcgi [Fri Apr 16 14:35:54 2010] [error] [client *.*.*.*] Premature end of script headers: dispatch.fcgi, referer: http://www.trac.****.com/login [Fri Apr 16 16:05:58 2010] [error] [client *.*.*.*] Premature end of script headers: dispatch.fcgi, referer: http://www.trac.****.com/timeline The trac instance has very low traffic so it is possible that this might have been triggered faster if there was more use of it. So next step i went to look at top and am amazed by what i see: (this is NOT exactly what i saw, i just reproduced this from memory) 23730 rl_inst 20 0 44516 15m 4012 S 0.0 0.4 0:00.17 python2.4 23731 rl_inst 20 0 44616 15m 4012 S 0.0 0.4 0:03.17 python2.4 23732 rl_inst 20 0 44116 15m 4012 S 0.0 0.4 0:01.17 python2.4 23733 rl_inst 20 0 44826 15m 4012 S 0.0 0.4 0:04.17 python2.4 23734 rl_inst 20 0 44216 15m 4012 S 0.0 0.4 0:02.17 python2.4 23735 rl_inst 20 0 44416 15m 4012 S 0.0 0.4 0:01.17 python2.4 I opened the trac site again and that changed to this: 23730 rl_inst 20 0 44516 15m 4012 S 0.0 0.4 0:00.17 python2.4 23731 rl_inst 20 0 44616 15m 4012 S 0.0 0.4 0:03.17 python2.4 23732 rl_inst 20 0 44116 15m 4012 S 0.0 0.4 0:01.17 python2.4 23733 rl_inst 20 0 44826 15m 4012 S 0.0 0.4 0:04.17 python2.4 23734 rl_inst 20 0 44216 15m 4012 S 0.0 0.4 0:02.17 python2.4 23735 rl_inst 20 0 44416 15m 4012 S 0.0 0.4 0:01.17 python2.4 28378 rl_inst 20 0 2608 1208 1008 S 0.0 0.0 0:00.00 dispatch.fcgi 28382 rl_inst 20 0 44248 15m 4012 S 0.0 0.4 0:02.19 python2.4 So the dispatch.fcgi was being called correctly and was spawning correctly other python2.4 process. After the IDLE time passed this is the results: 23730 rl_inst 20 0 44516 15m 4012 S 0.0 0.4 0:00.17 python2.4 23731 rl_inst 20 0 44616 15m 4012 S 0.0 0.4 0:03.17 python2.4 23732 rl_inst 20 0 44116 15m 4012 S 0.0 0.4 0:01.17 python2.4 23733 rl_inst 20 0 44826 15m 4012 S 0.0 0.4 0:04.17 python2.4 23734 rl_inst 20 0 44216 15m 4012 S 0.0 0.4 0:02.17 python2.4 23735 rl_inst 20 0 44416 15m 4012 S 0.0 0.4 0:01.17 python2.4 28382 rl_inst 20 0 44248 15m 4012 S 0.0 0.4 0:02.19 python2.4 dispatch.fcgi was gone but the corresponding python2.4 was still there o_O. I had started with 5 sleeping processes of python and after idle time i ended up with 6. I repeated this and found that it kept spawning more and more python2.4, this was indeed what was causing my 500s indirectly. Let me explain my findings. Am on a shared hosting so my processes get killed if they are way too many. So everytime i opened trac 2 new processes spawned and one remained, to the point that dreamhost was killing a random process when i reached my limit. Sometimes killing the python2.4 that actually was rendering the current page. Hence header premature ending, python is gone the .fcgi doesnt know what to do and throws an 500. I found a dirty solution to this. I changed my dispatch.fcgi to contain a line that killed any currently running python2.4 process and then spawn a new one. Since then i dont get any rogues what so ever. But i dont think this is the best solution, calling killall in every fcgi just seems wrong. Anyone has run into this issue and found a cleaner solution? Is there anything that i have overlooked?
