Apache CGI error.

[savage_cabbage]

Hi,
I'm using Apache/2.0.40 on Redhat 9. I'm trying to figure out how to permit CGI script outside of ScriptAlias directories. I added following code to my httpd.conf file:


ScriptAlias /cgi-bin/ /var/www/cgi-bin/

<IfModule mod_cgid.c>
#
# Additional to mod_cgid.c settings, mod_cgid has Scriptsock <path>
# for setting UNIX socket for communicating with cgid.
#
Scriptsock run/httpd.cgid
</IfModule>

...

#
# "/var/www/cgi-bin" should be changed to whatever your ScriptAliased
# CGI directory exists, if you have that configured.
#
<Directory "/var/www/cgi-bin">
AllowOverride None
Options +ExecCGI
Order allow,deny
Allow from all
</Directory>

...

#
# AddType allows you to add to or override the MIME configuration
# file mime.types for specific file types.
#
AddType application/x-tar .tgz

#
# AddHandler allows you to map certain file extensions to "handlers":
# actions unrelated to filetype. These can be either built into the server
# or added with the Action directive (see below)
#
# To use CGI scripts outside of ScriptAliased directories:
# (You will also need to add "ExecCGI" to the "Options" directive.)
#
AddHandler cgi-script .cgi .pl

<Directory "/home/*/public_html/cgi-bin">
Options +ExecCGI
</Directory>


And I put "test.cgi" file in my /home/david/publlic_html/cgi-bin directory:

#!/usr/bin/perl
print "Content-type: text/html\r\n\r\n";
print "Hello, World.";


Here is the error message I got:

Server error!

The server encountered an internal error and was unable to complete your request.

Error message:
Premature end of script headers: blah.cgi

If you think this is a server error, please contact the webmaster

Error 500
...

I checked the permissons and everything I could but still couldn't figure out why. Can anyone help me?

Try usiing the following code and see what happens.

#!/usr/bin/perl -w

use CGI;

$cgi = new CGI();

print $cgi->header(),"\n";
print $cgi->start_html(),"\n";
print "hello world";
print $cgi->end_html(),"\n";

sykkn,
I got the same error message. The strange thing is even if I don't put anything
in test.cgi except for #!/usr/bin/perl -w, I still get the same result.

have you uncommented out the following line

AddHandler cgi-script .cgi

if not then uncomment it out and restart the webserver and give it a shot.

[sykkn]

OK, sorry that didn't help just wanted to make sure that code I knew worked still didn't work for you.

I have found people saying they got that error due to permissions. Specifically write/execute permissions for users other than yourself. What are your current permissions? Try chmod'ing to 711 and see if that works for you.

I'll keep researching until I hear back.

[nikhil]

if you run it from the command line, does it work correctly?
try uncommenting the line if its commented:
AddHandler cgi-script .cgi

Yes, I did uncomment the "AddHandler cgi-script .cgi" line. And I set my permission to 755. I ran the script on command line and everything looks fine. Plus, I put the script in /var/www/cgi-bin/ directory and it ran fine there as well. The "Server error!" message is still there. I'm lost

[nikhil]

hmmm....
what happens if you put
Options ExecCGI
instead of
Options +ExecCGI
without the "+"

just trying out all possible avenues here...dont know if it might make
a difference but its worth a try....

[savage_cabbage]

nikhil,
I tried it and it's still not working.

[sykkn]

I read that you need different permisions to use the scripts is your public_html directory. Trying chmod'ing to 711 and running it and then try 770 and running it.
