Determining availability of a remote machine

Traceroute relies on ICMP.

You could always try a tcp connection and wait for a RST packet or a SYN
ACK, depending if the machine is listening on the port or not. You would
still need a timeout if the machine was dead though, but I can't see
anyway around that. And firewalls etc would still be in the way, but
firewalls are always going to get in the way, that's their job.
