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 --upas-nhoixypkgdwujtfgcfmpvopwai Content-Type: message/rfc822 Content-Disposition: inline Received: from plan9.cs.bell-labs.com ([135.104.9.2]) by plan9; Sat Aug 16 12:21:22 EDT 2003 Received: from mail.cse.psu.edu ([130.203.4.6]) by plan9; Sat Aug 16 12:21:20 EDT 2003 Received: by mail.cse.psu.edu (CSE Mail Server, from userid 60001) id 8752319B60; Sat, 16 Aug 2003 12:21:14 -0400 (EDT) Received: from psuvax1.cse.psu.edu (psuvax1.cse.psu.edu [130.203.30.6]) by mail.cse.psu.edu (CSE Mail Server) with ESMTP id 575D419A40; Sat, 16 Aug 2003 12:21:10 -0400 (EDT) X-Original-To: 9fans@cse.psu.edu Delivered-To: 9fans@cse.psu.edu Received: by mail.cse.psu.edu (CSE Mail Server, from userid 60001) id 1332319B60; Sat, 16 Aug 2003 12:20:12 -0400 (EDT) Received: from rgristroph-austin.ath.cx (cs24356-14.austin.rr.com [24.243.56.14]) by mail.cse.psu.edu (CSE Mail Server) with ESMTP id 646C1199FD for <9fans@cse.psu.edu>; Sat, 16 Aug 2003 12:20:10 -0400 (EDT) Received: from rgr by rgristroph-austin.ath.cx with local (Exim 3.35 #1 (Debian)) id 19o3r0-0008C7-00; Sat, 16 Aug 2003 11:24:34 -0500 From: rgr@sdf.lonestar.org (Rob Ristroph) To: 9fans@cse.psu.edu Subject: Re: [9fans] The 9grid.

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 ? --Rob 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. --upas-nhoixypkgdwujtfgcfmpvopwai--
