Don't run _any_ internet listening daemons that are not explicitly
required. For desktops especially, this can amount to none at all.
>How do I find out how he got in?
Well, you probably don't. You can look for weird log entries in
/var/log/* (standard script kiddie procedure is to run a script that may
or may not succeed in removing suspicious log entries). You can back
track through your mind and remember if any of the daemons running were
vulnerable and guess it was one of those.
>What is asp62 which he installed on my system?
Well, it probably provides a root shell without a password, or it is a
simple proxy program (a "bounce") for more cracking or harassing on IRC.
>I'm going to reinstall even though it looks like he didn't finish.
That's what I would recommend. Before you plug the network cable back
in, disable (and delete) all the daemons that are running after the
Boy, that script you showed sure shows how script kiddies got their
name. They don't even know how a simple shellscript works.
