Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

You need the name of the process, but killall is a BAD solution to killing a single ssh login. The best way (if you want to do this) is to use "ps" to find the PID of their root bash session (listed as -bash, usually) and then kill -9ing it.
It's hard with ps to see who is connected to who..
Try netstat -tanp and locate the ESTABLISHED connection that matches.
The PID to kill is in the right hand column.
Don't use kill -9 if you can avoid it. It doesn't always allow the daemons to clean up temp files, locks etc. Use kill -TERM PID or kill -15 PID
