I got them running.

One respondent clued me in to the factory default password. Another gave
me links to some online documentation. Another gave me some
configuration lines:


DEFINE SERVER INTERNET ADDRESS ##.###.##.#
DEFINE SERVER INTERNET SUBNET MASK AUTOCONFIGURE DISABLED
DEFINE SERVER INTERNET SUBNET MASK ###.###.####.#
DEFINE SERVER INTERNET PRIMARY GATEWAY ADDRESS ###.###.###
DEFINE SERVER INTERNET BROADCAST ADDRESS ##.###.##.###


That information, some additional web searching, and some playing around
got the job done. Basically, it appears that the bootp process on the
Xyplex MaXserver 1600 is partially broken. These date back to when the
protocol was brand new. Anyway, they don't get their netmask and gateway
properly from bootp.

also, I had been trying

SET SERVER INTERNET ADDRESS ##.###.##.#
SET SERVER INTERNET SUBNET MASK ###.###.####.#
SET SERVER INTERNET PRIMARY GATEWAY ADDRESS ###.###.###

unfortunately, that appears to be useless. it sets live memory, and I
thought it would use it, but it doesn't seem to. I can set all that, try
telnet, and still not be able to get out of my subnet.

using DEFINE instead of SET sets the non-volatile memory, which then
gets used on the reboot. then everything works and I can telnet out of
my subnet.

I also tried pulling the power plug when I went home, plugging it back
in the next morning, and it worked just fine when I plugged it back in.
So they are resistent to power outages in this way -- I won't have to go
running in to reconfigure them.

>From here it is just refinement and security. At the moment the bootp
redirects them to my tftp server where they get their load file. I would
like to be able to get them to load their configuration and a menu as
part of the boot process. then I could take all the security and
additional configuration stuff that I have and get it into all of them
without having to type it in to every single one.

Thanks to all those who helped.

Anyone familiar with Xyplex MaXserver 1600 Terminal Servers and their
bootp process?

I've inherited a situation where support was dropped and the people who
did it are no longer available. I have to get them working from my own
server. I've set up bootp and tftp and managed to get them presumably
doing a bootp and getting their load file from my server, but it only
works within my subnet. I can't get it across subnets for the branch
libraries, and I just realized that the ones that "work" here cannot
telnet across campus. When I connected with a terminal and asked it to
show me the server's IP configuration (SHOW SERVER IP at the Xyplex
prompt), the subnet mask and gateway had not been set. But the bootp
server is configured to set both of those.

If someone is familiar with this kind of setup, I would greatly
appreciate being able to exchange a few technical questions. At this
stage I don't know whether I should be focusing attention on the
terminal server configuration or on my setup of bootp on the server.

One thing that might be useful is if I could force the whole thing to
factory settings with some default password for SET PRIVILEGE that would
allow me to get in and control everything. At the moment, I can control
some configuration information by going in under single user mode; but,
there is other stuff that appears to be available if only I had a
password (these things ran for years without any intervention, people
retired, other people got moved to other projects and departments, ...)

xyplex was a strong believer in security by obscurity. in the single
user mode it claims it is busy loading if you hit the return key. but,
if you type "access" and return, you get a menu that allows you to
change the basic configuration. I can also telnet to a running terminal
server, but it doesn't give me any prompt and I don't know what it is
looking for. I have about a dozen of these among three branches.

Anyway, I could fill this up with other questions, but there is no point
unless I get some response to the basic questions.

TIA
