Are you running apache chrooted? .. it might be a problem with that if yes and you would need to make the sylinks relative not absolute.
To exemplify:

instead of
Code:
ln -s /path/to/file /path/for/symlink
try
Code:
cd /path/for
ln -s ../../to/file symlink

Red face httpd sym links problem

the answer is yes and the links are already relative as per ur suggestion, could there be a global configuration which is blocking sym links?. which is not in httpd.conf?

Where is the cricket directory located? .. is it under the /var/www/html ? It's ahrd to really help when you dont know the setup. Have you tried without +?

Edit: if your symlink target dir is outside the directory for which you enabled FollowSymLinks your apache will not be able to follow the symlink.
Be careful with the directory-path arguments: They have to literally match the filesystem path which Apache uses to access the files. Directives applied to a particular <Directory> will not apply to files accessed from that same directory via a different path, such as via different symbolic links.

Regards
Andy

I wasnt clear enough. You may add a new directive for /home/cricket/cricket it doesnt matter. Your /var/www/html will not be able to follow links outside /var/www/html. In your case apache will refuse to follow symlinks inside /var/www/html that leads to /home/cricket/cricket. I repeat myself "if your symlink target dir is outside the directory for which you enabled FollowSymLinks your apache will not be able to follow the symlink." So you do not need to add:
Code:
<Directory /home/cricket/cricket>
Options FollowsymLinks ExecCGI
</Directory>
because the most you will is to specify that all symlinks inside /home/cricket/cricket are to be followed within the boundaries of the PATH apache uses to access those files.

I don't know if you are running the 2.6 kernel with SELinux enabled, but here is something else to consider:

Don't forget to also check SELinux permissions on the directory with
ls -Z /home/cricket/cricket

http://systemnotesorg.blogspot.com/2...otes-http.html

You may have to run
chcon -R --reference /var/www/html /home/cricket/cricket
to allow the web server to read the files.

Question httpd sym links problem

there is anew twist to the saga, i have just made some adjustments, i had a link pointing to another link in the cricket directory
as in from /var/www/html/cricket to /home/cricket/cricket the second cricket directory is actually a link within the /home/cricket directory to the actual directory- cricket-1.0.5so i suppose thats where the problem was coming from, now i have removed this sym link and have a link from /var/www/html to /home/cricket/cricket-1.0.5 which is the actual cricket config directory,
the symlinks not allowed error in th logs is gone but now the problem is the cgi scripts like grapher.cgi in cricket-1.0.5 are not running
, from the browser u get a text file instead of a graph

i have got +ExecCGI in my httpd.conf
