Output of w command
I get the following output when i execute the w command:
Code:
[root@machine ~]# w
 22:35:16 up 73 days,  8:43,  4 users,  load average: 1.27, 0.38, 0.18
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT
root     :0       -                23Aug09 ?xdm?   5:57m  0.11s /usr/bin/gnome-session
root     pts/1    122.160.37.239   22:31    0.00s  0.01s  0.00s w
root     pts/2    :1.0             28Oct09  7days  0.01s  0.01s -bash
root     pts/4    :2.0             28Oct09  7days  0.01s  0.01s -bash

What does the ":1.0" and ":2.0" mean under the FROM column for the last two bash entries?

X11 display numbers.

That means x11 was forwarded via ssh? pts/# in the TTY column means remote login i guess.

pts just means a pseudo-tty is used, it might be local or remote.
In any case, :1 and :2 should be local X servers.

Please note that this command output format is Gnu/Linux specific and the documentation, as often, is quite terse on details.
