Hello Tymm Twillman, I know about kill -9 -1 problem is not in kill, kill behaves itself as it should, but in X reaction to kill. Someone can hang console by starting and killing X server. It's not a big problem - just another one of this kind in X Window without X authentication. But it's more dangerous then running password protected screensaver on another user's screen :) 28.05.00 21:01, you wrote: Local DoS : RedHat 6.0; T> -1 as a process ID argument to kill is handled by SVR4 and 4.3+BSD by T> sending the signal to all processes whose real UID or saved UID is the T> real or effective UID of the process sending the signal (except the signal T> sender if under 4.3+BSD).

You still can't kill others' processes.
