That's exactly what I do. I turn on my emergency system every couple of weeks, "emerge --sync" and "emerge --ask --deep --update --world", run etc-update if necessary and then shut down. I have a honking big 19" CRT on my desk at home, and the KVM is used elsewhere. The machine name is m450 (450 mhz PIII). My main machine is m3000 (AMD64 3000+). There is an ordinary user "waltdnes" on m450. /etc/sudoers on m450 contains the following line... waltdnes m450 = (root) NOPASSWD: /sbin/poweroff I have a short script ~/bin/stopm450 on m3000 ... #!/bin/bash ssh [EMAIL PROTECTED] sudo /sbin/poweroff To shut down... 1) via ssh shut down unnecessary programs on m450 2) exit all ssh sessions to m450 3) stopm450 -- Walter Dnes <[EMAIL PROTECTED]> In linux /sbin/init is Job #1 My musings on technology and security at http://tech_sec.blog.ca -- gentoo-user@gentoo.org mailing list
