grant the user (restricted) sudo access then run your commands as "sudo command"

read up on sudo(man sudoers) and look for "NOPASSWD:"
ex:(from man page)
Quote:

ray rushmore = NOPASSWD: /bin/kill, /bin/ls, /usr/bin/lprm

oh, the apache server isn't on the hardware node.
i think you need to setup passwordless ssh.
Quote:

ssh-keygen -t rsa
scp .ssh/id_rsa.pub someuser@hardwarenode:.ssh/authorized_keys


then in php have:
Quote:

system("ssh -n -F /home/someuser/.ssh/config -i /home/someuser/.ssh/id_rsa someuser@hardwarenode 'sudo /usr/sbin/vzlist'");

Hi,

have you setup your sshd to use the .ssh/authorized_keys ?
