I am running CentOS 5.3 and have just the two accounts "root" and "buz". I would like to be able to issue "shutdown" from the account "buz", and thus created /etc/shutdown.allow with the single entry "buz" (without any quotes). I still get the error message "only root can do this" (or something similar) even if I include the '-a' option on the shutdown command. What am I missing ?
I'm not going to verify this right now but I believe "buz" can execute the command "poweroff" to shutdown -h now and "reboot" to shutdown -r now.
[rj@mavis rj]$ ls -l `which poweroff` lrwxrwxrwx 1 root root 13 Apr 2 2009 /usr/bin/poweroff -> consolehelper [rj@mavis rj]$ ls -l `which reboot` lrwxrwxrwx 1 root root 13 Apr 2 2009 /usr/bin/reboot -> consolehelper [rj@mavis rj]$
From the man page:
If halt or reboot is called when the system is not in runlevel 0 or 6, in other words when it's running normally, shutdown will be invoked instead (with the -h or -r flag). For more info see the shutdown(8) manpage.
