retrix bridge problem, automount, AMD

[Dirk Grunwald]

4 Q's:

+ we have 2 Enets, OT-1 & OT-2, connected by a retix bridge. We have a
  demo RS/6000 running AIX 3.1 living on OT-1. When we power up the
  machine, it'll see machines on OT-1 & OT-2. Eventually, it only sees
  machines on OT-1.

  the following is the ifconfig.

	/etc/ifconfig en0 
	en0: flags=2000063<UP,BROADCAST,NOTRAILERS,RUNNING,IFF_NOECHO>
	       inet 128.138.243.85 netmask 0xffffff00 broadcast 128.138.243.255

  this is an occasional problem, but it happens enough to make us
  wonder if we want these boxes. Checking 'arp -a' after it stops
  talking to OT-2 show no arp entries for hosts on OT-2. Entering the
  arp entries doesn't make the hosts reachable. Anyone ever seen this
  before?

+ What's the diff between 'en0' and 'et0'? What's a standard ethernet
  and what's 802.3? I thought 802.3 WAS std enet.

+ I can successfully YPBIND the machine to a sun, but when I attempt
  to run 'automount' using the auto.master from the sun-4 (4.0.3), the
  rs/6000 complains about the options entries. Does it need its own
  set?1

+ likewie, 'amd' doesn't work very well. I had to hack on amd-5.6 a
  little to get it to compiler. Do people use 'amd' and if so, what
  version and how did you get it to work?
