I haven't tried this on FreeBSD, but several years ago I had to do some single user work on an SCO OpenServer box in Texas. I had the owner of the machine start sshd in single user mode, then I could ssh into the system to work. The SCO box activates the network in single user. FreeBSD would probably require starting network services manually. Bill -- INTERNET: bill@Celestial.COM Bill Campbell; Celestial Software LLC UUCP: camco!bill PO Box 820; 6641 E.
