Request for enlightenment re `rwhod"

[Jay Lepreau]

The problem is probably simply that the 4.2 rhwod throws away malformed
packets, which is OK except that the check is overly stringent and it
throws out all hostnames with '-' in them.  Change an "isalnum" in
rwhod.c to "isprint", say.

I am really do expect your ethernet is a broadcast medium and that
IFF_BROADCAST is set; try ifconfig <device>. (like "il0"). (Course
ifconfig had its bugs too, but they shouldn't affect this.)
