| # who
| root pts/49 Nov 9 13:10 (hostname.domain.xx)
| where you see that there's an connection to pts/49 in my case.

| # ps ax | grep "pts/49"
| 32265 ? S 0:00 sshd: root at pts/49
| 32267 pts/49 S 0:00 -bash
| 32663 pts/49 R 0:00 ps ax
| 32664 pts/49 R 0:00 grep pts/49
| Here you see there's active connections thru sshd and an shell
| -> 32267 pts/49 S 0:00 -bash
| then just as root give the command
| # kill -9 32267
| and the connection should drop. If there's no shell for the

Thanks a lot for the reply. Since I did a clean FC3 install last night
;) all the zombie processes are gone for now. I tried looking through
before but I didn't find anything I could kill; but the next time I will
definitely try the 'ax' modifier.
Thanks again and yes, that was exactly what I was looking for. But I
thought there might be more _elegant_ solution like 'killuser' or
something else of that sort.
