170ac683f2 I've been meaning to do this for a while. Add an underscore to the
time_to_xxx() and xxx_to_time() functions.  e.g. _time_to_xxx()
instead of time_to_xxx(), to make it more obvious that these are
stopgap functions & placemarkers and not meant to create a defacto
standard.  They will eventually be replaced when a real standard
comes out of committee.

4de932048c Ensure that received packets are at least as long as the rwho packet
header before trying to process them. Without this sanity check,
rwhod can attempt to byte-swap all of memory when a short packet
is received, and so dies with a SIGBUS.

While I'm here, change two other syslog messages to be more
informative: use dotted quad rather than hex notation for IP
addresses, and include the source IP in the 'bad from port' message.

471595b02c Fix minor buffer problems:
Off by one in verify allowed one to march one byte off the end of
	wd.wd_hostname if wd.wd_hostname had no NUL characters in it.

	strncpy of myname into mywd used the source buffer's length, rather
	than the dest.

90ff799227 When looking for "group daemon" (since that's what's in mtree), make sure
we actually look for the *group* and not the user's gid.  user daemon
has traditionally been group 31 (guest).

Also clear out the groups vector so that it doesn't inherit the groups
of the invoking user (ever run rwhod by hand before?)  Unfortunately, we
can't empty the supplemental groups list because the !&@^#! egid is stored
in there! :-(

84f8341ef7 Here are patches to add full multicast support to rwhod, and an updated man
page.  I tried all three modes (rwhod, rwhod -m, rwhod -m 32) on a machine
with 2 ethernet interfaces and they all worked.
