Almost there; networking the XL....

Ever since I sent my second message to this list the machine had been
running non-stop and perfectly for over a day. I bought all the
networking hardware I needed yesterday and decided to go for it and
power down the machine so that I could hook up the transceiver and
connect it to the Linux box. When I powered it back up, the keyboard
was working perfectly, and has been. So I guess the problem magically
disappeared (well, I did pray a lot that it would...).

Anyways, I've spent many hours reading the networking docs and trying
to get things working and I haven't had too much luck (especially
since my changes to things were making the docs unreachable and I had
to use the less searchable hardcopy stuff....).

Basically, here is my setup: I've got a Linux 2.2.x box with a modem
that connects to the internet via PPP and has one ethernet card. The
XL is the only other machine on the network. The network is
192.168.0.0, the Linux box is host HAL, 192.168.0.1. The Symbolics is
host TRILOGY, 192.168.0.2.

When I first set things up this way, I changed a line in
FEP0:>Local.boot from

  Set Boot Options :Network Address internet|192.42.172.3

to

  Set Boot Options :Network Address internet|192.168.0.2

and then in the Namspace Editor I edited all the various objects and
whenever I saw 192.42.172.3 I changed it to 192.168.0.2, and
192.42.172.0 to 192.168.0.0. When I first rebooted, I was able to ping
the Symbolics from the Linux box. The login screen looked something
like this though:

  This machine is Home INTERNET|192.168.0.2, a Symbolics XL1200.

instead of

  This machine is Home Trilogy, a Symbolics XL1200.

Also, I got a notification at this time (or maybe it hadn't come yet,
but eventually I got this notification)

  [6/2 14:22:27 Namespace Home is unloaded:
		No longer server for this namespace.]

and sometimes the variation (from memory):

  [6/2 xx:xx:xx Namespace Home is unloaded:
		No longer server for this namespace.
		Recent servers contacted: Trilogy]

I did a lot of Find String commands to replace every last occurance of
the old IPs with the new yet whenever I tried to use host TRILOGY like
e.g. Edit File TRILOGY:>cbarry>whatever I would get a window about
"Host Trilogy (192.42.172.3)" being unreachable. The old IP was
somehow persisting despite my attempts to replace every last trace of
it. So in order to access files I would have to do
INTERNET|192.168.0.2:>....

Eventually, I was able to reverse all the changes I had made but it
took a number of reboots and now the machine is back to displaying
Host Trilogy on startup and working good with the docs online, though
still stand-alone. I'm unable to ping it again even if I try to do
what I remembered doing the last time I got pinging from the Linux box
to work.

Host Trilogy was previously configured to talk to a NeXT box and a
Mac. I've attached most of TRILOGY:>sys>site>home-objects.text to the
bottom of this email. I think things would be much easier if none of
the network stuff was configured so that I could start from scratch
instead of trying to migrate the in-place settings which have mystical
persistance properties, but I don't know how to do this. I'm pretty
stumped.

Oh yeah, in the course of playing with all this stuff I always
rebooted like:

  Command: Halt Machine
  FEP Command: Clear Machine
  FEP Command: Hello
  FEP Command: Boot

To try to clear any persistant low-level network configuration
stuff.

Thank you for any pointers,
Christopher

[Most of TRILOGY:>sys>site>home-objects.text (hopefully nothing
relevent has been elided). Don't forget, I'm typing all of this out by
hand because the boxes aren't talking yet. Also, some lines were
removed from some records like LPD printer stuff etc.... Ultimately,
I'd like the setup below to work with my site, Host Tarkus becoming
Host HAL, my Linux machine.]
