This is directed to those people who have had experience installing
a second (enp0) Etherboard on the VME buson a 4D/25 (or comparable machine).
I have done just that but I appear to be having a number of problems.
If you have any hints or suggestions or see anything glaringly wrong with
what I have done (see below), please Email me ASAP.
Following the guide, I installed the board, using the System Manager
tool to turn off and on the Yellow Pages and TCP/IP (looked like black magic
to me). The machine in question is a disk server, a name server, a YP
server as well now a gateway. It didn't auto-reconfigure at first
because I was having trouble seating the board. This is the first piece
of SGI hardware which has not impressed me; one of the board's mounting
screws broke; the drop cable fitted the socket poorly so I had to do a
little re-fitting of the cable's locking pins so it was snug; the board
sticks out so far that the drop cable won't let the box close.
Eventually, after 5 or 6 reboots and refits, the system
auto-reconfigured and recognized the board. The single machine that
was on the new subnet (besides the gateway), refused telnet/rlogin
attempts although rup/ping worked fine. The gateway suffered two
kernel fault crashes. I can't ping the gateway machine at its new
address from itself or any other machine.
Previously, I changed the entries in our local master
name server (which the new gateway is secondary for) to reflect the double
nature of the machine's addresses (local domain 132.206.9.0; new subnet
is 132.206.123.0 as provided by local Internet authorities). I set the
option ipgateway in /usr/sysgen/master/bsd on and rebuilt the kernel.
Now, to make matters worse, the gateway is refusing telnet/rlogin
attempts from other machines. I can't seem to find anything in the manuals
that I missed. I am feeling thoroughly incompetent today.
I know this is all rather confused but I am a bit worn out and
I need some help. I don't have time to go to the Hotline today. I
usually find this list to be faster anyways.
Please ask any questions that seem pertinent to you if you are
interested in helping.
Thanks,
