When your system is not responding and you do not want to reboot, you can kill a process on your system from a remote machine using the rlogin command.

This example shows you how to log in to a remote host, use the ps command to delineate processes and then use the kill command to end the frozen process:

$ rlogin hostname

password:
Last login: Tue Jun 8 17:40 :30 from venus

$ ps -e
