Giving out your machine name's not going to give anyone a clue about
where your machine is (unless it is something obvious, like some
resnet host e.g. tark-a-043 or something).

TCP wrappers isn't the best approach to securing your machine, IMO.
A good firewall will do a better job of that than anything else (and
it's more low-level than TCP wrappers, which allows packets through
anyway).

What the line above says is that someone connected to your portmap
daemon from 203.68.244.15 (a noticeably Australian/NZ IP address).
Whether that is good or not depends on what you intended.

In short, I think you're being overly paranoid about what has happened
and not paranoid enough about protecting your machine.
