problem with old consoles

[bsdfunn]

Hello

I have some troubles with old console sessions (after closed or crashed SSH connections, they don't expire). How i can can I kill/clear idle TTYs?

Try killing the sshd(8) process. Run % ps x | grep sshd and kill(1) all expired connection/s.

Note: pgrep(1) and pkill(1) can simplify things.

Yes, good shot

ps x | grep sshd
65074 ??  Is        0:00.00 /usr/sbin/sshd
68564 ??  Ss        0:00.01 sshd: nick@pts/1 (sshd)
68601  1  S+        0:00.00 grep sshd

But w/ who show idle console connections.

But w /who show idle console connections.

Yes, but not show the process ID (PID). Read ps(1)() man page.

As in certain cults it is possible to kill a process if you know its true name.

This is my current SSH connection.

Anyone?

Or if you prefer, run % fstat /dev/pts/[num] and then, use the PIDs that you get from fstat(1)() to kill the connection/s.

E.g.

[CMD]% fstat /dev/pts/0[/CMD]
USER     CMD          PID   FD MOUNT      INUM MODE         SZ|DV R/W NAME

charly   csh        72927   15 /dev        148 crw--w----   pts/0 rw  /dev/pts/0
charly   csh        72927   16 /dev        148 crw--w----   pts/0 rw  /dev/pts/0
charly   csh        72927   17 /dev        148 crw--w----   pts/0 rw  /dev/pts/0
charly   csh        72927   18 /dev        148 crw--w----   pts/0 rw  /dev/pts/0
charly   csh        72927   19 /dev        148 crw--w----   pts/0 rw  /dev/pts/0
