Re: [U2] Not Consistent Failure
Thanks for the help on this one. That one gave me just enough information to figure things out. First, when the login failed, I saw an error message There are running jobs... just as the process should have been passed to Universe. That was odd, so I checked the output of the truss command, and it appeared only in the stream of the failed logins. Then I got to thinking, hey, I remember a seldom seen bug in AIX (and a couple of other OSes) where if the PID table because full, and thus had to start at the beginning again, sometimes it wouldn't know a PID wasn't in use any more because it hadn't been cleared from the table correctly, and give some anomalous errors. So, I did 'uptime' and saw they hadn't rebooted the system in 60 days. I used to work for this client and know they have a month-end checklist that includes rebooting the server as part of closing out each month. So, I rebooted the system, and then logged in as 'bob' (the user who captured his screen for us to give things a go), and never once had a failed login after 30 or so attempts. It's been a long time since I was involved so deeply at the OS level of a system, so I really appreciate the help on this one.

So, here goes: I have a client that has started experiencing a login anomaly. First, the use telnet, and second, they don't have passwords at the Unix level. They are on AIX 5.2.0.0 with Universe 10.2.12 The things I've seen are: - the session doesn't make it into UV for their password prompt but drops straight to Unix. - I've checked permissions at various locations and at various levels. - I've commented out various parts of both /etc/profile and /u1/ACCT/.profile with no consistent noticeable change. - I've checked UV.LOGIN and ACCT LOGIN as well and nothing has changed in either place, and they are performing minimal tasks. - I've added a sleep just before exec /u1/uv/bin/uv plus changed uv to uvsh to see if that mattered. It didn't change the failures. - Failures are either on the 2nd login, 4th login, 3rd and 4th, 6th and 7th, 2nd and 3rd and 5th or whenever the pattern can't be matched... In other words, there's no rhyme or reason that can be applied to this failure. This is a real head-scratcher for me and I'm hoping someone has seen this or has something to offer.
