Smith (bvsmith@lbl.gov) However, I would like to remind you that, should someone become root who wishes to hide that fact, and should /var/log/authlog be someplace that the root-ed person can touch... well, lets just say that your log means nothing in this case, since root can go edit that file and remove the entries. Or even change them to reference someone else rather than themselves. Nope, sorry, but once someone becomes root the logs mean nothing if that person knows where they are (and how to change them). I could tell you a long story about this as it relates to the Univac 1100 series, but then this is comp.UNIX.wizards.... ^^^^ ---------- Rusty Carruth UUCP:{uunet,boulder}!cadnetix!rusty DOMAIN: rusty@cadnetix.com Daisy/Cadnetix Corp.
