If the two machines have fixed addresses there's no reason to use
dns at all.

You should have a /lib/ndb/local that lists the network with the
appropriate auth server and fs server.  For example:

ipnet=robsnet ip=199.199.9.0
	ipgw=199.199.9.1
	fs=199.199.9.2
	auth=199.199.9.3

Or you can use symbolic names instead of the ip addresses:

ipnet=robsnet ip=199.199.9.0
	ipgw=199.199.9.1
	fs=robsfs.rob.net
	auth=robsauth.rob.net

ip=199.99.9.2 dom=robsfs.rob.net
ip=199.99.9.3 dom=robsauth.rob.net

and if you want them to boot off of a plan9 dhcp/bootp/tftp server

ipnet=robsnet ip=199.199.9.0
	ipgw=199.199.9.1
	fs=robsfs.rob.net
	auth=robsauth.rob.net

ip=199.99.9.2 dom=robsfs.rob.net
	ether=123456789012
	bootf=/386/9pcfs
ip=199.99.9.3 dom=robsauth.rob.net
	ether=123456789013
	bootf=/386/9pccpu

This is related to question I have.

I have two computers with Plan 9 installed on them, on an IP only
network that has no DNS.

If I want to set up one as an authentication / cpu server, and the
other as a disk server.  ( A third Plan 9 computer, or drawterm on
linux, will be used to acess them. )

Do I need to set up DNS just so I can specify the authdom variable in
the appropriate scripts ?  In other words, to run an authentication
server do I need to have a DNS server running somewhere ?

Or can I give authdom a list of IPs, or a subnet ?

P.S.  I am currently trying to solve my problem by running a DNS
server on a linux machine, but that just turned into another problem,
i.e., why doesn't it work.
