Re: kill a stale user session?
Got nothing from "ps aux|fgrep acheng@ttyp4". No SSHD process to kill either. The problem for me is that no process belongs to ttyp4, but "w" still reports an idle session.

kill a stale user session?
Hello all, I'd like to kill an stale user session, but could not find a way to do that. Seems like there is no process attached to that ttyp4 any more. It's an OpenBSD 5.1 on i386, by the way. Any advice appreciated. some output, more will be provided if necessary. #w 7:44PM up 12 days, 23:19, 2 users, load averages: 0.10, 0.14, 0.18 USERTTY FROM LOGIN@ IDLE WHAT acheng p0 180.116.63.38 6:00PM 0 w acheng p4 114.227.123.110 27Jul12 9days - <-- the one I'd like to kill #ps -t p4 PID TT STAT TIME COMMAND thanks. acheng
