Depending on what O.S. level you are running, you can set up
your ethernet port to have two IP address via IP aliasing.
I'm not sure what is the lowest IRIX level which supports this,
but you should be able to get an SGI Indy to run 6.5.20, which
certainly does support it.
Steps:
1) At the bottom of /etc/config/ipaliases.options add a line like:
ef0 alternate.address.edu netmask 0xffffff00 broadcast xxx.yyy.zzz.255
(make sure your change netmask and broadcast appropriately)
2) Then "ckconfig ipaliases on", or change /etc/config/ipaliases
from "off" to "on"
3) Add "alternate.address.edu" to your /etc/hosts file. Do not list
the second address as localhost, and do not list it as an alias.
It needs its own unique line in the file.
4) Reboot the computer, or run "/etc/init.d/aliases-ip stop" and then
again with "start." (restarting network will not work.)
You should see both IP addresses with "ifconfig -a"
You can also test it with another SGi, by typing on the local
machine "snoop <remote-address>" and on the remote machine, type
"ping <new alias>" You should see evidence of a successful ping
at both ends. Then ^C to stop.
You will also need to connect your SGI into a switch, with one port
going to the local network, and one going to the spectrometer.
I think that's it, let me know.
