Someone hacking via gnome?

[jesse andrew cmu edu (Jesse F. Hughes)]

This morning, I found gnome applications crashing.  Finally I
rebooted, and then noticed this in the messages file:

Since I use a dynamic IP, the attacks stopped after rebooting.  The
little shit lost me.

The child seems incapable of being more than a nuisance to me, but
what is he connecting to via gnome?  Is there anything serious he can
do?  How can I keep him out?

Thanks.
