Nevermind this last email.... from a different box :)

In addition to my previous email, I found the following:

% ps auwx |grep login
root 587 0.0 0.1 1604 1220 p0 Is 5:39AM 0:00.01 login [pam] (login)
root 57250 0.0 0.1 1604 1232 p1 Is 7:44AM 0:00.02 login [pam] (login)
root 6162 0.0 0.1 1604 1236 p2 Ss 11:08AM 0:00.01 login [pam] (login)



Looks like the login process executed via PAM is not exiting (I had only 1 user logged in at this time...), so I guess this is most likely a bug in login?


Thanks.

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.
