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. FYI: $ ps aux|fgrep acheng@ttyp4 $ w 9:57PM up 13 days, 1:31, 3 users, load averages: 0.16, 0.18, 0.23 USER TTY FROM LOGIN@ IDLE WHAT acheng p0 180.116.63.38 6:00PM 1:50 -ksh acheng p1 114.227.120.20 8:06PM 0 w acheng p4 114.227.123.110 27Jul12 9days - $ ps aux | grep ksh acheng 13452 0.0 0.1 548 500 p0 Is 6:00PM 0:00.02 -ksh (ksh) root 25705 0.0 0.1 632 528 p0 I+ 6:07PM 0:00.07 -ksh (ksh) acheng 30721 0.0 0.1 480 488 p1 Ss 8:06PM 0:00.02 -ksh (ksh) acheng 28924 0.0 0.0 480 4 p1 R+ 9:57PM 0:00.00 -ksh (ksh) $ ps aux | grep sshd root 16212 0.0 0.2 656 1208 ??
