Perfect for > checking local hosts or sweeping through a range of IPs to see who's up Also, fping in /usr/ports/net/fping may be appropriate. A tool to quickly ping N number of hosts to determine their reachability without flooding the network. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping. Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion. If a host replies, it is noted and removed from the list of hosts to check. If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable. Unlike ping, fping is meant to be used in scripts and its output is easy to parse. -- Matthew Hunt * Think locally, act globally. finger hunt@mph124.rh.psu.edu for PGP public key.
