Perl script server error 502

Upgraded to Windows Server 2008 and Instructor login Perl Script for iTunesU stopped working. It now gives...
"Server Error 502 - Web server received an invalid response while acting as a gateway or proxy server. There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server."
Login scripts for Public and Student access still work fine.  Has anyone else ran into this error?

Hi,
The forums have been having problems for about a month or so. The 502 error is less frequent than the generic 'Internal Server Error' pages, but they've been noticed as well:

The best way to report this issue is to send in an email to fissues (at) microsoft [dot] com with a link to the URL you received the error from and when it happened.

  • Using ARR to forward OWA requests to Exchange (On Premises) gives Server Error 502

    I have been struggling to configure a Windows Essentials Experience and Exchange On Premises system for our company.  
    I have two hyper-v guest servers running Server 2012 R2, one with the Windows Essentials Experience role installed and one with Exchange 2013.  After weeks of trying to get various parts of the configuration installed, following the various Microsoft
    guides, I thought I had finally managed to do it but have failed, again, at the final hurdle.
    Exchange is working and users can connect to OWA from inside the domain using the same URL as the external URL.  However when accessed from the internet we get "502 - Web server received an invalid response while acting as a gateway or proxy server."
    I have tried to do some tracing in IIS but don't seem to get any results.  Can anyone shed any light on how to resolve this issue so I don't have to tear any more of my hair out!
    Thanks in advance

    Hi RicoE,
    On current situation, please go to
    Microsoft Remote Connectivity Analyzer and run a test, then monitor the result.
    In addition, please refer to Post-installation tasks section in following article, then check if correctly
    set up an on-premises server that is running Exchange Server on a Windows Server Essentials network.
    Integrate an On-Premises Exchange Server
    with Windows Server Essentials
    Please also refer to following KB and check if can help you.
    FIX: ARR does not route requests correctly when you use the
    ARR module in IIS 7.0
    By the way, please use the
    Configuration Troubleshooter tool that Robert created to check IIS and Certificates.
    If any update, please feel free to let me know.
    Hope this helps.

  • In Web Server 6.0 during the execution of a Perl Script, the software send the error "Cannot execute CGI script......unable to sewt group".

     

    Hi Pablo,
    Its bcos Your web server has been misconfigured. It doesn't know that it should execute your Perl program, so it's just returning the error to the browser.
    Assuming that u use solaris 2.8. Generally the path for the perl in solaris is #!/usr/bin/perl .make sure u have included this in ur first line of the perl programs.[if not enter the exact location of the perl interpretor]
    Now follow these steps:
    *First Part
    First create a cgi folder mycgi-bin( follow this example please) say u create mycgi in /usr folder (solaris). so the path becomes '/usr/mycgi-bin'. set
    appropriate permissions say set chmod to 755. to make it executable. Then
    (1)Goto Programs tab in IWS (iplanet web server) .
    (2)choose cgi-directory drom left frame.
    (3)CGI Directory Add another CGI Directory
    URL prefix: mycgi-bin
    CGI directory: /usr/mycgi-bin
    (4) click 'OK' and click 'apply' to save changes and restart the server.
    * Second Part:
    1.In the Server Administrator, click Server preferences, then select 'MIME Types' from the frame on the left.
    2.If you want to use .pl as the extension for Perl scripts, find and remove the application/x-perl MIME type (this is mapped to .pl by default). (remove it).
    3.Add a new MIME Type with 'magnus-internal/mycgi-bin' (type this exactly ie magnus-internal/cgidirectory url prefix) as the Content Type, and pl as the File Suffix.
    4.Save and apply these changes, then re-start the server.
    5 .Put a sample perl file in mycgi-bin directory say sample.pl and access http://yourserver:port/mycgi-bin/sample. pl
    *If you are having trouble running Perl scripts on your iPlanet server, check the following:
    * Ensure that the script is readable by the account used by the iPlanet service.Generally, this means you should make the script readable by the Everyonegroup.
    * Ensure that all supporting files, like the perl binary files, the perl library files, and the modules that you use, are all readable by the account used by the iPlanet service (i.e., the Everyone group).
    It should work now,
    Regards,
    T.Raghulan

  • Run perl script on remote server

    Hello
    I have 2 servers, server 1 and server2.
    I have a perl script on server2 and I want to execute that perl script so my code is like
    $command= { param($p1,$p2) cmd /c test.pl $p1 $p2 }
    Invoke-Command -session $sesion -ScriptBlock $command -ArgumentList 1,2
    session is already created with server2 from server1. 
    perl script kept on server2 spawn another cmd which interacts with server3.
    When I run above code that perl script start executing but it stays in executing step for infinite time..as per observation, I have found that it stucks when it tried to spawn another cmd which interacts with server3 from server2.
    How can I handle this?

    Second hop restriction and some issue in the perl script that prevents it from honoring the error.
    Run script interactively to test results.
    Enter-PsSession $session
    Type your command and see if you see an error.

    Hi Harminder,
    This happens because an app has already been deployed and you are deploying it again using the same version.
    Resolution:
    Open the AppManifest.xml file and change the version.

  • To write a perl script for running a java program from cgi of web server

    I have to write a perl script to call a java program(.exe).I want to run this file through the cgi of the web server.
    java myprogram
    can anyone help me to write a perl script??

    It depends on what the java program does. For example, does it parse HTTP headers from standard input, or what?
    Are you sure it wouldn't be easier to turn the class into a servlet? etc.
    Take a look at IPC::Open2 and IPC::Open3 though. You may need them. (That's just a guess.)

  • Risport Service: The remote server returned an error: (502) Bad Gateway

    Hi All.
    I am using the CUCM (System version: 6.1.3.2000-1) Risport function to get device information.
    When trying to connect to the service (https://<CUCM_IP>:8443/realtimeservice/services/RisPort) I receive the folowing error:
    The remote server returned an error: (502) Bad Gateway
    When entering the same URL into the browser on the same application server I get a Security Alert, user prompt and eventually the expected screen. So the service is running, but somhow I can not connect to it using the application.
    Does anyone know how to solve this?
    Thanks in advance

    It is an C#.NET Windows Service.
    I have solved "the problem". The service was running with "local system account". That user did not had the right proxy rights to connect to the CUCM service.
    So I changed the Windows Service user to the account that I use to login on that machine (with the right proxy rights) and now it is working ;-)
    I figured this out because when I logged into that machine, with my account, I could connect to the CUCM service without any problems with my browser.

  • How to resolve error - 502 web server error ?

    Hello,
    Kindly consider following scenario: 
    Custom control is programmatically creating site using following code. Once site get created, it redirecting to its settings.aspx page:
    try
    SPSecurity.RunWithElevatedPrivileges(delegate()
    using (SPSite
    site1 = new
    SPSite(SPContext.Current.Site.ID))
    SPLongOperation.BeginOperation
    beginOperation = null;
    if (beginOperation ==
    null)
                             beginOperation =
    delegate(SPLongOperation
    longOperation)
                                 site1.WebApplication.Sites.Add(site1.RootWeb.Url 
                      + "/manPath/site1,
    Site1, "", 1033,TemplateName,
    __userLoginName, __userName,__userEmail);
                                 longOperation.End(site1.RootWeb.Url
    + "/manPath/site1/_layouts/settings.aspx");
    SPLongOperation.Begin(beginOperation);
    Same code works perfect at development machine, while in production it gives 502 web server errors.
    Please check below error text:
    502 - Web server received an invalid response while acting as a gateway or proxy server.
    There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.
    Results in Development machine: site gets created and redirects to its site settings page as expected.
    Results in Production machine: During the process it throws 502 web server errors, while site has got created successfully.
    I am not sure why it happened, while previously it was working. I have feeling that may be redeployment should resolve the issue, but I want to know root cause of this issue!!
    Note :  the same settings page is working well, when I open it manually in production environment!
    Please let me know the approaches to resolve this issue? Also, let me know if you need any further information on same.
    Thank you to look at this issue !
    Kind Regards,

    Hi, I have found the things where is the issue , but still I am looking for the resolution !
    To add further on above issue, I have observed as below :
    Client machine: Following
    error is getting throw when creating new  site. 
    502 - Web server received an invalid response while acting as a gateway or proxy server. 
    There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content
    server, it received an invalid response from the content server. 
    WFEs
    machine : Error is not getting display when creating new site.
    And hence , it looks like load balancing/IIS issue, however I am not sure how to resolve the same !! 
    Please let me know your thoughts !

  • Rman/PERL scripts errors

    I am trying to automate the backups and disk maintenence on a test machine using a "Host Command" in the 10g EM environment. If I run the script from the command on the target host the scripts completes successfully.

    Is anyone having this problem in 10g and if so , can you provide me with some insight with respect to resolution?

    The .sh script calls a perl script that parses the output of the report obsolete command in rman and deletes the obsolete datasets from disk. This shell completes from the command line with no errors. Here is the .sh and the perl script. Like I said the odd thing is that this shell executes successfully from the command line. Thanks for your interest in looking at this.

  • Unix Perl Script To verify a Up and Running Database on Different Server

    Unix Perl Script To verify a Up and Running Database on Different Server
    Hi
    can any one please tell me a solution to verify a Up and Running Database on Different Server other than the one where we run the unix perl script? The perl script should check if the database is running else it must exit.
    Thanks much
    Kiran

    The other best solution would be Enterprise Manager, load the EM on the other machine and install oracle intelligent agent on all the boxes where oracle is running and problem solved.
    FTP is only a File Transfer Protocol, you can upload/download the files but cant execute them.
    Apart from EM the best way is load oracle client and make connection to all the databases.
    AND There are some free oracle monitoring software available I dont know much about them but one is NAGIO (if I am not wrong), try that if you want.
    BTW whats the problem in monitoring the boxes from the same physical box, means just schedule a script using cron on the same physical box where oracle is to either make connection using SQLPLUS or check the processes using "ps" command and if there is anything wrong then send alert from that box only. In this way there is no need to maintain a central monitoring server.

  • I have perl scripts that I want to be able to run with my iplanet web server 6.0. How can I make it work in Windows NT? (Because I have no problem when I use it with Linux).

     

    Hi Melanie,
    In order to run a PERL script under Windows NT the iPlanet Web Server needs to know where to find the PERL interpreter.
    follow these steps :
    1) Make sure Windows NT knows what a .pl file is. In file Manager click on file and choose associate from the menu. Check the "files with extension" drop-down list for pl - if it exists verify that it is pathed to your perl.exe. If it is not already on the list click the "New Type" button. In the Filetype box put pl. Choose open from the Action drop-down list. In the Command box specify the full path to your perl.exe interpreter (Make sure to use short filenames, rather than long filenames.) Click the OK button. Then click the Close button in the main Associate dialog box. Double click a .pl file to test - it should automatically launch the PERL interpreter and feed it your .pl file.
    2) Create a directory to contain your .pl scripts.
    ~server_root\shell-cgi is a good choice.
    or \cgi-bin\
    NOTE: Make very sure that this directory is NOT part of the document root, it should have it's own directory (preferably at the same level of the docroot).
    3) In the Admin Server select Programs.
    4) Choose CGI directory (normally) or WinCGI directory or ShellCGI Directory depending on ur choice from the Programs menu.
    5) Put the URL Prefix you would like to map to your Shell-CGI directory into the URL Prefix field.
    6) Put the full path to your Shell-CGI directory in the Shell CGI directory field.
    7) Click OK.
    8) The save and apply changes page will display your changes and give you the opportunity to verify them. If they are correct click the Save and Apply button. If not Click the Undo button and go back to step 4.
    (9)You can then call your .pl scripts directly by referencing the directory mapping that you have just created. For example:
    http://my.server.whatever/shell-cgi/ myscript.pl
    this should work now.
    If not Pls Mail me.

  • Error 1047 in LabVIEW 8.2: LabVIEW failed to send variable to the script server. Server:""

    I am working with the evaluation version of labVIEW as well and I have run into another error.  I am using a MATLAB script node within a for loop and attempting to pass the for loop counter variable into the script.  When I run the code it brings up a 1047 error and says "LabVIEW failed to send variable to the script server. Server:"" ".  I looked up the error online which seems to have roots in a failed auto initialization of MATLAB.  Is there something that I can do in labVIEW to fix the problem or is it strictly a MATLAB error?  
    I really appreciate your help.

    I'm using Labview 8.6 and Matlab 7.9 2009b on windows 7 (64bit)
    when I tried to open the Lorenz Diff Eq.vi....it woes not work and gives the error
    Error 1047 occurred at LabVIEW:  LabVIEW failed to send variable to the script server. Server:"" in MATLAB script node - Lorenz Diff Eq.vi
    I think there is no inital communication for opening the MATLAB server
     any can help?

  • Perl script running - "text file busy" error?

    Hiya--
    Recently, whenever I try to run a perl script, I get the following error:
    tcsh: nameofscript.pl: Text file busy.
    The permissions on the perl script are set to 755, and this error message occurs whether I type "nameofscript.pl" or "./nameofscript.pl" at the prompt. The initial line is of the script is
    #!/usr/bin/perl
    Has anyone else encountered this problem? I can't for the life of me figure out why it's occurring now. (I've run this script before without any problems. It's only within the last 2-3 weeks that this error pops up and won't go away, and only for .pl scripts.)
    Advice much appreciated.

    Hi Mahesh,
    I could suggest you some services that you may stop in Windows platform.. If not You may look into some services
    with analogous names and stop them. But you may go about stopping all database and SAP J2E services.
    The services are
    saposcols
    sapj2e00
    sapj2e01
    Hope this helps.
