Request for enlightenment re `rwhod'

rwhod underwent two major changes with respect to making it listen and
talk with other 4.1[abc] and 2.[89] systems.  The packets sent by the
4.2 system now has some sort of version info (check the rwhod.h file
for the structure definition).  The 4.2 rwhod also flushes all incoming
packets that don't have the correct version (all other non-4.2
systems).

the other major problem I had was getting it to find the IFF_BROADCAST
bits in the interface flags.  It turned out that /etc/ifconfig was
zeroing the flags word instead of oring them.  You might also check
your ethernet driver (if_il.c or if_ec.c or ?) to make sure that those
flags are actually set.

I sent out the fixes I made to /etc/ifconfig to unix-wizards over two
months ago.

My pet flame about rwhod is that it checks for isalnum in the host
name.  Our host names have a dash in them so I had to change it to
isprint.
