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.

We have a transparent squid proxy server and working fine. I will be using last, w and who cammands to check the currently logged in users and though there will be only two users, one is limited user and other is root, I have also disabled the direct root login using ssh.
My question is why it is showing about 3 logged in users in uptime and w command's output, while who is showing about only one logged in user and even only one user is is logged in. Please see the below details.
if you login via ssh as an ordinary user, there is one user.
If then "su" there is still only one user, who has logged in.
The su'ed user has no login shell running.
And that is, what "who" and "w" are showing.
And of course there are running processes from more users, than are logged in.
Hi..Thank you all,
I did not find any other users information even from who -l, who -m, who -a commands and showing only Admin information that I am logged in into proxy remotely. So it seems no need worry and as you said it may be showing about system users.
Once again thank you all for your kind response.
