Lewis,
Trying again (last attempt to send hung netscape).
I don't think that loosing NVRAM has caused your problem but am not
sure. My reasoning for this is that I had a look at one of my RC3230's
(whose TCP/IP works fine) and could find no PROM monitor value that
seemed to have any relevance (the only possible one was netaddr=97.0.0.0
but the systems IP address is 134.211.64.201).
I have attached a procedure that I use to setup TCP/IP on MIPS.
Have fun,
Terry

Setting up TCP/IP on a MIPS system
1. Setup /etc/local_hostname as per below manually or is done on install:
# vi /etc/local_hostname
sales
netmask 0xffffff00 broadcast 134.211.64.255
#
2. Setup /etc/local_domainname as per below manually or is done on install:
# vi /etc/local_domainname
melb.au.wang.com
#
3. Setup /etc/hosts as per below manually or is done on install:
# vi /etc/hosts
127.0.0.1 localhost
134.211.64.201 sales
#
4. To check setup, run the below:
# hostname
sales
#
# domainname
melb.au.wang.com
#
# ifconfig la0
la0: flags=63<UP,BROADCAST,NOTRAILERS,RUNNING>
inet 134.211.64.201 netmask ffffff00 broadcast 134.211.64.255
#
5. If not using DNS or NIS, just add entries into /etc/hosts for the other
systems.
6. If going through a default router, add an entry into /etc/init.d/netdaemons
similar to "route add default 134.211.64.1 5" after the heading "Add
routing commands here".
# vi /etc/init.d/netdaemons
#! /bin/sh
#
# Initialize/Shutdown the network daemons.
#
# $Header: netdaemons,v 1.5.1.5.1.1.1.2 90/10/05 10:00:56 beacker Exp $
PATH=/net:/bin:/etc:/usr/bin:/usr/etc:/usr/ucb:
not() {
eval ${1+"$@"} && return 1 || return 0
}
**** I have deleted lots of entries as are not relevant ****
# Add routing commands here
# Example: "route add destination gateway 1"
#
route add default 134.211.64.1 5
portmap > /dev/console 2>&1 &
echo " portmap\c"
inetd
echo " inetd\c"
**** I have deleted lots of entries as are not relevant ****
#
7. To check setup, run the below:
# netstat -r
Routing tables
Destination Gateway Flags Refs Use Interface
Netmasks:

Route Tree for Protocol Family 2:

localhost 127.0.0.1 UH 1 0 lo0
134.211.16 134.211.64.100 UG 0 0 la0

(root node)
Route Tree for Protocol Family 6:
(root node)
(root node)
#
8. If using DNS, create the following files:
# vi /etc/vis.conf
host: files dns
#
# vi /etc/resolv.conf
domain melb.au.wang.com
nameserver 134.211.64.203
