I am trying to run a command/script that requires root privileges when a non-root user logs into ssh

This unfortunately means I cannot use ~/.bashrc or /etc/bashrc

I also tried /etc/ssh/sshrc but it has the same problem, the command executes as the logged in user.

I see /etc/profile.d/ does something but not sure how to use it or if it will have the same problem.

sshd does run as root so I am hoping it can be taught to do this somehow

I do need to know the ip of the login for the command.

Thanks for any ideas!

added: sudo is not possible because it's for a non-privileged user without sudo rights

Please include the actual command you need to run (answers will be different for scripts and compiled binaries for example). –  terdon Jul 8 '13 at 18:36
    
Setuo sudo. Use sudo ... where required. –  Zoredache Jul 8 '13 at 18:38

Use pam_exec as a PAM session module.

Oh wow, I never knew about PAM. Reading up now, looks very promising. Any ideas how to grab the remote ip since it doesn't look like it's included in the PAM environment? –  ck_ Jul 8 '13 at 18:44
    
@ck_: It's in the PAM_RHOST 'PAM item', but pam_exec exports it as an environment variable ($PAM_RHOST) as well. –  grawity Jul 8 '13 at 19:15
