Sorry but you'll need to be a bit clearer in what the problem is, could you please provide some more information?

You can differentiate two or more Linux Machines using there hostname. For many linux distors the default prompt is "username@hostname".

If you mean what I think, try http://linux.die.net/man/1/who

You might want to take a look at this as well. It shows how to use different colored prompts for root and different users. If you make the hostnames different colors as well its a good visual cue for the machine you are working on.

The question if vague I agree.

Would you say that you mean? We have a linux computer A. We have a user Bob account on both computer B and computer C.
Can I tell if Bob is logged in from Computer B or from Computer C by some way?

actually i want to trace the user machine and disable him,force him to login through a recognized server

User@hostname. That is the general way to differentiate users on a network. Do you want to trace the actual machine or the user?

we want to trace system, can we also categorize it trough group id.

Is the requirement to identify a Linux system that is logging in to another Linux system?

If so, how is the logging in being done? ssh? An HTTP form? X display manager?
