gnokii working in linux command line but not in php system command, pls, help.

Question

gnokii working in linux command line in rhel5 but not through php system command, what to check? pls help.

Answer 1

What is most likely happening is that SELinux is (correctly) preventing httpd from executing gnokii. httpd runs as httpd_t, gnokii is labelled as bin_t, and there's no domain transition from one to the next. Solutions include disabling SELinux completely (not recommended), allowing httpd_t to freely execute bin_t (also not recommended), and giving gnokii a new file context and creating a domain transition rule for it.

Running man httpd_selinux gives a bit more information, but in order to create a new transition rule you'll need to see the various resources linked to on the SELinux website.

Answer 2

Even after disabling SELinux, its not working.

then by analysing /var/log/httpd/error_log file, we found that its not initialising properly, its reading .gnokiirc file from "//.gnokiirc" instead of "/home/my_user_name/.gnokiirc" which is not available.then it is loading the configuration available in /etc/gnokiirc file, which is not modified for our requirement. So, we modified it, now its working.....

thank you for your reply.
