	The problem was with calculating the icmp checksum.
most *BSD oses cared about it, while others did not.

	I don't have a FreeBSD 5.3 host lying around, just 5.4
and 6.1 mostly.  Both have run sysmon without troubles and are used
in my development work.  Give the latest rev a shot, it should work
without problems.  I just have mostly cosmetic cleanups to
do before a release.
