am i being hacked?

when i type uptime i get this:
10:42:29 up 1 day, 20:11, 5 users, load average: 0.23, 0.32, 0.65

when i type who:
tearinox tty1 Nov 9 15:23
tearinox tty2 Nov 9 14:38
tearinox pts/0 Nov 10 18:34
tearinox pts/1 Nov 10 18:35
tearinox pts/2 Nov 11 00:09

going through my terminals, i only have two users connected (tty1, and tty2) that are running locally.

What are the pts/1 and pts/2? and how do i get rid of them?

thank you

Provided your system is "sane", as root, run (w/o outer quotes):
"lsof -p $(/sbin/fuser /dev/pts/*|cut -d ":" -f 2- | tr " " ",")" or "/sbin/fuser -vu /dev/pts/*" or "find /proc/[0-9]*/fd/ -ls | grep pts" to see what processes have pseudo tty's open.

Most likely not. Verify your systems integrity if you want to be sure.

Those are your terminals in X (Konsole, Gnome-Terminal, xterm, Eterm, whatever you're using). But that had me stumped at first too.

Well this had me curious tho. I left my computer on overnight and it was acting a bit sluggish. Of course i figured i would just kill them but after i did that, i realized that i shouldn't written them down *tearinox smacks his head*

Is there a log that tells me what users are doing what by default? Or where are all the log files in gerneral? thx

All the logs files are in /var/log, check them all carefully and look for anything
out of the ordinary.
Be sure to follow UnSpawn's advice too.
If everything is safe, install aide.
It's an integrity checker and can detect changes in files, so it gets pretty hard
for anyone to crack your box and change stuff.
