File Permission problem on perl -cgi program

nagivreddy93 has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I have given a 777 permission for file (-rwxrwxrwx 1 nagios nagios 75 May 2 13:27 set_bpi_perms.sh), when I run the program on Console (terminal), it's works perfectely but in the web(cgi) it's not working properly.

below are the users and group access permissions:

/etc/group file
nagios:x:500:
apache:x:501:
nagcmd:x:502:apache,nagios

Below is the error displaying when i run in cgi program:

File bpi.conf is not writable! Please execute the following commands as the root user to set correct permissions:
cd /usr/local/nagios/share/nagiosbpi
chmod +x set_bpi_perms.sh
./set_bpi_perms.sh
and bpi.conf file also having a 777 permission

The code is working perfectely on other servers, i have deployed a code on new server it's getting error messages
Please let me know your ideas on this ..

Thanks Reddy.

Please let me know your ideas on this .. You describe an impossible situation, so one of your assumptions must be wrong, the solution is to test all assumptions :) Maybe the programs cwd is wrong, maybe the program is running in a chroot jail or some other kind of sandbox....	[reply]

Web servers are often fussy about running commands that can be modified "too easily". A script that allows anyone to modify it certainly would fall in that category. Try mode 555. (Do you really want to allow any user to modify your scripts? Making any file writable by everyone is asking for trouble).	[reply]

Does this server happen to have SELinux enabled? If so, you have to check the security context of the file (chcon), as well as the usual read/write permission settings (chmod). Or else you could simply disable SELinux...	[reply]
