Internal Server Error Perl

of questions I get from my visitors at thesitewizard.com, I can see that one of the most dreaded errors that newcomers to CGI face is the "500 Internal Server Error". It is one of the most uninformative error messages that can internal server error cgi python mean anything from an improper upload to a bug in the script. This article attempts to cgi script internal server error give you some concrete, practical steps that you can take to narrow down the problem and hopefully eliminate it. For the uninitiated, a apache cgi-bin 500 internal server error "500 Internal Server Error" is a message much like the common "404 File Not Found" message. You get the latter message in your browser when you try to access a non-existent web page. You get the "500 Internal internal server error cgi-bin apache Server Error" message when you try to run a script with problems. For the purposes of this article, I am assuming that your CGI script is a Perl script, by far the most commonly available on the Internet. We will try to eliminate the most common errors first (and the easiest-to-eliminate ones): Location Did you upload your scripts into the right place? This is not as obvious as it may seem. Some servers are configured to

run your CGI scripts anywhere. Others will only run it when it is installed in a particular directory. It is not just a matter of creating a "cgi-bin" directory — for example, some hosts configure the server so that it will run scripts only from a particular directory outside the web directory structure (for security reasons). Your web page will still call the script "/cgi-bin/script.pl" but the server maps it to the actual directory. You will have to upload it in the right directory, regardless of what your web page calls it. Find out such information from your web host's documentation. File Upload Mode Did you upload your Perl script in ASCII mode? Your FTP client may have uploaded the script in binary mode if you did not take any special action. Perl scripts are ASCII files, and since different operating systems have different ways of representing the end of line character (eg Unix uses a line-feed, Windows uses a carriage-return and line-feed pair), it is important that you set the uploading method to ASCII, so that line-end translation is performed. Re-upload the script, this time making sure that it was uploaded in Text or ASCII mode. Do not use any auto-detection options since the FTP program might assume the extensions you are using for your scripts are for binary files. File Permissions Did you change the permissions

The short answer: this is usually a permissions error on your CGI script, which is easy to fix. Go to your FTP client, or http://www.thesitewizard.com/archive/servererror.shtml your website file manager, and highlight or right-click on the CGI script. Then choose Properties, or Permissions, or "Chmod", and set it to world-executable: that's 0755, or a+rx, or -rwxr-xr-x. Do NOT use 0777 (a+rwx or -rwxrwxrwx). And your cgi-bin directory itself should also be 0755, not 0777. The long answer: when running a Perl CGI script like FileChucker or UserBase, you may see the "Internal Server Error" https://encodable.com/internal_server_error/ message in your browser. The message will usually also say something like "please check the server's error-log for more information." You should do that -- the message printed to the error log will often tell you exactly what the problem is. The Apache error log, for example, is often located at /var/log/apache/error_log or /var/log/apache2/error_log (or sometimes "error.log"). If you don't have access to the error log, the next simplest thing to do is to make a backup copy of the script, then open the original and delete all of its contents, and add just these 3 lines to the file: #!/usr/bin/perl print "Content-type: text/plain\n\n"; print "testing...\n"; (Note: if the server is a Windows system, then replace the first line above with either #!perl or #!c:\path\to\perl.exe.) Now try to access the page in your browser again. If it works (you see "testing..." as its output) then you know that your server is at least configured properly for running Perl CGI scripts. If it doesn't work, then that may mean the problem is in the server configuration, rather than with your CGI script. (For example, are you sure you actually have Perl installed? Virtually all UNIX/Linux/OS X servers do, but Windows servers usually need

There are a number of causes for a 500 Internal Server Error to display in a web browser. Below is a sample error message. This article provides information on the most common causes. Check the Error Logs! With any error message, particularly one as broad as the 500 Internal Server Error, you will first want internal server to check any Apache and PHP error logs for your server. These logs can provide valuable context related to any code failures or other potential causes of a site failure. For information on where to find the logs for your server, please see: Where are the access_log and error_log for my server? Error with an .htaccess file If you are using a .htaccess on your site, it may be interfering with the web internal server error page you are trying to load into your browser. Please double check the .htaccess configuration. Any syntax errors will cause a 500 Internal Server Error message to be displayed instead of your website. To confirm whether a misconfiguration .htaccess is the cause of the 500 Internal Server error, either remove or rename the .htaccess file temporarily and then try to reload the page. See also: Using .htaccess rewrite rules Using .htaccess files PHP Coding Timing Out If your PHP script makes external network connections, the connections may time out. If too many connections are attempted and time out, this will cause a "500 Internal Server Error." To prevent these time outs and errors, you'll want to make sure that PHP scripts be coded with some timeout rules. Typically, however, catching a timeout error when connecting to a database or externally to remote resources (example: RSS feeds) are difficult. They, in effect, freeze the script from continuing to run. Removing any external connections can increase both the performance of your website and decrease the chances of you receiving a "500 Internal Server Error." Syntax or coding errors in your CGI/Perl script If it is a web page ending in .cgi or .pl that is producing the error, check your script for errors.
