What is "normal" output of who?

I was just wondering about the output of who. When I run who with from a terminal in X the output is something like this when I should be the only active login, in this case as root:

PHP Code:



root@dtest:~# who 
root     tty1         2010-01-06 07:51 
root     pts/0        2010-01-06 08:24 (:0) 
root     pts/1        2010-01-06 08:24 (:0.0)

If I run who from the console with no X started I only get

PHP Code:



root@dtest:~# who 
root     tty1         2010-01-06 07:51

Is this normal and can someone tell me what the second 2 outputs mean exactly, I understand that one of them would relate to display 0, but I'm not sure which or what the other would mean then.

$ who
craig tty7 2010-01-04 23:52 (:0)
craig pts/0 2010-01-06 08:52 (:0)
craig pts/1 2010-01-06 06:46 (:0)
craig pts/2 2010-01-06 09:31 (:0)
tty7 is X, the others are the 3 tabs I have open in lxterminal. One would assume they are instances of bash running. And if I look at lxtask , there are 3 bash processes running.

Thanks. I was wondering because on a new slackware install ssh logins take forever to authenticate compared to a previous test install of the same setup causing me to get nervous to the point of shutting down sshd which is a hassle to say the least.

Don't forget that ssh -vvv will give you very, very verbose logging, so maybe you can see what is going wrong.

I hadn't known that to forget, but I'm very glad to know it now!

Thanks
