-* 08-24-1999 Didi Rieder (adrieder@sbox.tu-graz.ac.at)
-*            Intial Coding
-* 09-11-1999 Karl DeBisschop (kdebiss@alum.mit.edu)
-*            Change to spopen
-*            Fix so that state unknown is returned by default
-*            (formerly would give state ok if no fping specified)
-*            Add server_name to output
-*            Reformat to 80-character standard screen
-* 11-18-1999 Karl DeBisschop (kdebiss@alum.mit.edu)
-*            set STATE_WARNING of stderr written or nonzero status returned
-* 09-29-2000 Matthew Grant (matthewg@plain.co.nz)
-*            changes for monitoring multiple hosts for checking Internet
-*            reachibility
-*
-* Description:
-*
-* This plugin will use the /bin/fping command (from nagios) to ping
-* the specified host for a fast check if the host is alive. Note that
-* it is necessary to set the suid flag on fping.
