faking a plan9 network

[Russ Cox rsc@research.att.com]

I understand this is a non-standard setup.  Please
bear with me.

I have a standalone Pentium Plan 9 terminal.  It runs
kfs for a file system; everything is great.
I want to make an old 386 another Plan 9 terminal.
Its connected via an Ethernet and I can boot
off disk1 from the ftp site.  I can also get it
to boot (using disk1) a kernel from the Pentium,
that is, from e!0.

The problem is that I want to have the root file
system be from the Pentium as well.  I tried giving
it il!192.168.96.11!17008 as where root is from,
and it worked to the degree that /bin/service/il17008
gets called on the Pentium.  I copied the il17007
file and made it il17008.  Even if I take the -a
out of the exportfs command line, I get authentication
errors from the 386 trying to boot, and it just 
prints out the standard hex dump and hangs.

This is probably because I don't have an auth server.
I suppose that I need to fake an auth server in 
addition to faking a file server, but I don't want
to dedicate a computer to being a cpu server (to run
auth stuff on) because all I've got are the two terminals
that both need to be able to be used as terminals. 

So does anyone have any good way to fake an auth
server on a terminal?

Thanks.
