This is usually adequate to tell that a remote host is available to rsh(1), ftp(1), or telnet(1) to. So the standard library may be sufficient, but not necessarily so. In addition to the above, you can also try the net/ping from rubyforge, or possibly even rubyforger to craft your own ARP or ICMP packets.
