I'm one of the horde of IDS newbies - I believe I saw the reference on the firewalls list (either there or bugtraq). I'm sysadmin for the central Unix machines here at Dartmouth, and have had my level of paranoia increased recently with the release of the SATAN stuff (*very* nicely done, BTW), as well as some things happening here locally. I'm interested in intrusion detection for the obvious reasons. Pat Wilson pat.wilson@dartmouth.edu
