It makes no difference if I add or remove this in ISPConfig:

<Directory "/var/www/web7/cgi-bin">
Options ExecCGI
</Directory>

In ISPConfig Webpanel I have activated CGI for this Vhost.

File is set to 755.

What do I wrong here?

Help please. Thank you.

Please create a administrator user for the website and then chown the cgi script so that it is owned by the web admin.

[Elfchen]

Thank you for your very fast reply on my post.

Can you please tell me how to create an administrator?

I think I have to create the admin in ISPConfig "User and email" and to activate administrator. Is this correct?
How do I find out the chown settings for this administrator then? Should I use the nix-user web7_admin:x:10004:10007:admin:/var/www/web7 then?

The result would is:

-rwxr-xr-x 1 web7_admin web7  117 2008-07-23 17:42 hello.pl

Think I have done in this way (see last post) - but no change - result like before - error 500

btw. the cgi-bin directory was automatically updated to new owner by ISPConfig, too:

drwxr-xr-x  2 web7_admin web7 4096 2008-07-23 17:53 cgi-bin

"Premature end of script" errors often has to do with wrong ownership or wrong permissions.

If the administrator of your site is web7_admin and your webnumber is web7, you can set the right settings for the script by executing:

chown -R -v -f web7_admin:web7 scriptname

Where scriptname is your real scritname.
Make sure that "CGI-scripts" are allowed for the site.

[Elfchen]

Thanks. This was the correct solution.

chown -R -v -f web7_admin:web7 hello.cgi
Eigentümer von âhello.cgiâ in web7_admin:web7 geändert

So the solution is quite easy:

1. Create an admin user (ISPConfig web-settings: User & email)
2. All rights are changed to the new admin user by ISPConfig
3. Files where you have changed rights are not automatically changed - it need to be done manually
4. All works!

Thanks to both for fast reply and correct answers!
