It would help to phrase your questions a little more precisely. I am not 100% sure if i understand you correctly and this is what you want to know:

To see from where you yourself are being logged on use the command who (the first is logged in locally via GDM, the second one is connected via a network connection):

Code:
# who -u am i
bakunin  pts/1        Jun 21 13:38   .         12386 (:0.0)
# who -u am i
bakunin  pts/2        Jun 21 13:41   .         12423 (my.system.com)

To see which system you are logged on to use the hostname command:

Code:
# hostname
my.system.com

I hope this helps.

we want to trace the machine and disable it, this way we can login through only
from recognized Server.

What Operating System and version is this?
What command(s) do the clients use to connect to the Server?
