To reboot the system, > > % shutdown -r now Here are some much saner solutions (in increasing order of preference): 1. Add the users who are permitted to shut down the system in group operator. 2. If group operator doesn't suit for other reasons, create a new group "shutdown", chgrp shutdown /sbin/shutdown, and add your users to that group 3. Best of all, install sudo and put the people in your sudoers file, which allows you to give permissions to individuals, groups defined in various ways, with effect on various machines or networks, with or without passwords, etc, etc. The man pages describe this in great detail. -- Greg Black <gjb@acm.org> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
