I found this very interesting when I saw it originally, but then found it was probably a bug. Basically, when I log into my 5.1-RELEASE box (compiled today from CVS), I can do a 'w' and get the following: % w 10:39AM up 5:01, 1 user, load averages: 0.00, 0.00, 0.00 USER TTY FROM LOGIN@ IDLE WHAT ray p0 somehost 10:39AM - w Now, when I try to SU to root, this entry changes: % su - Password: Last login: Tue Jun 24 07:44:19 on ttyp1 % whoami root % w 10:40AM up 5:01, 1 user, load averages: 0.04, 0.01, 0.00 USER TTY FROM LOGIN@ IDLE WHAT root p0 - 10:40AM - w So, it looks like the utmp entry is being made (again) for ttyp0 and recording it. This would be fine from my perspective, but is misleading once I exit the root shell: % exit % whoami ray % w 10:42AM up 5:03, 1 user, load averages: 0.01, 0.00, 0.00 USER TTY FROM LOGIN@ IDLE WHAT root p0 - 10:40AM - w This may be a bug in PAM, since I don't think su calls login (or maybe it does?) Note that this does not happen if I do not use the '-' option for su. This also shows up in the lastlog: root ttyp2 Tue Jun 24 10:40 - 10:43 (00:02) ray ttyp2 somehost Tue Jun 24 10:39 - 10:40 (00:00) Anyone have any information about this... know what the bug is? Maybe it's a setting I have set that can be changed? Thanks.
