It's a tool. Granted, that dopey ASCII art thing is pretty dumb, but I got over it, and it's a valuable addition to my toolbox.

You may not realise that to do lots of useful things, you need to be root. Had a look at ping(1) recently? It's setuid root, because only root may issue icmp packets.

And your firewall will of course block any egress attempts from the host on which you run this program, right? I doubt there's a rootkit in there, but I haven't looked closely. I imagine that if there was anything fishy going on, we would have heard about it by now.
