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.

414a35e60a Add $Id$, to make it simpler for members of the translation teams to
track.

The Id line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

471595b02c Fix minor buffer problems:
Off by one in verify allowed one to march one byte off the end of

	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.
