Take a breath and.... good luck ! : About a year ago I wrote a little program that takes a time-spec as command : line argument and tells you who was logged in at the time. I remember there : are lots of login records *without* matching logout records in wtmp. Yes, it happened in FreeBSD-2.0.5 if I remember ! But even 2.1.5 has been fixed... : E.g. if you type 'login anotheruser' from your login-shell there will be no : entry in wtmp for logout, just another login record for your line (tty). Well, I use to work with bourne shell (/bin/sh). I tried your experiment and it works as expected. No bugs, ac runs okay. Maybe your "libutil" has been corrupted... Maybe the shell you're using is not updating the wtmp properly... : My program and last(1) know about that but maybe ac(8) doesn't? Rather strange since last and ac look in the same file (wtmp) !!! : Probably I'd better look at the sources (or use gdb) rather than making wild : guesses here... Try different shells, I suspect there may be a problem with a builtin login facility! : Martin Regards, Philippe. -- ------------------------------------------------------------------- P.
