Hi, 1. You really don't have to include su as a sudo command as its accessible for all users (/bin/su). 2. For running a command with sudo privilege you've got to change /etc/sudoers file. Hope you have done that. 3. Check /var/log/secure, /var/log/message for the reason you getting error message. Regards, Kurian Thayil.
