Can you add a password so that Ms. Anybody cannot walk up to my Sparc and boot single user? Also, would this change prevent Ms. Anybody from booting from some device other than disk and then poking around the file system? SparcStation 1, SunOS 4.1. Thanks for any help! -- Kenneth H.

Take 'secure' out of the entry for the console in /etc/ttytab. It'll make it exactly like any other terminal; also, any attempt to boot single-user (or shut down, or whatever), requires giving the root pwd, whether or not you were root when you shut it down. Perfect for when your server's not well isolated. -- Brendan Kehoe - Widener Sun Network Manager - brendan@cs.widener.edu Widener University in Chester, PA A Bloody Sun-Dec War Zone "Visualize a dream; look for it in the present tense -- a greater calm than before.
