|
I'm relatively new to gentoo/linux, and I'm trying to figure out whether by box has been hacked or exploited.
My first indication was at a lan party recently, which wasn't connected to the outside world, when I quit out of X, I had a whole string of error messages that "/usr/sbin/sendmail can't connect" which worries me, as I don't use any mail programs.
I also had some problems last night with agetty, and not being able to kill it - every time I tried it restarts itself. Though looking at other people's posted ps -aux, it seems that having four agetty processes running is not abnormal.
My basic question is this. How do I go about determining if I've been hacked? Are there signs I should look for, files I can check?
Any help would be great. Thanks!

This could very well be ssmtp trying to send you information about cron jobs.

That's what getty processes do - they're waiting for people to log in to them, and init respawns them. Don't worry about this one either.
ktb's advice is great, but I think the probability that you need to worry is very low.
