Re: Need help setting IP address on DS20 (VMS 7.3)

I inherited a DS20 ... I was warned that I would not be able to change
the IP address of it, the warning mentioned that others before me had
tried before, but they always just gave up and let it be.

Why would a IP address be so hard to change?
What if you boot a Tru64 or a new VMS installation?

Anyway, I *need* to change the IP.

Check your SRM variables if there is any IP address set.
I don't know why one would have done this but just to be sure.

This was originally a 7.1-2 box, and was upgraded to 7.3 some time back.

btw: You know that V8.3 is current?

Apparently, perhaps form the upgrade, it's set up in some sort of UCX
compatibility mode - I say that because when I remove the TCP*.DAT and
UCX*.DAT files, and run TCPIP$CONFIG, it creates the TCP*.DAT files
then, also, one UCX dat file. Also, UCX$CONFIG runs TCPIP$CONFIG (after
telling you that it will).

Do you mean the (empty) UCX$SERVICE.DAT?

In TCPIP$CONFIG, there is exactly one interface: IE0. (The SRM
identifies the NIC as EIA0 and TCPIP$CONFIG calls it IE0, if that
matters at all.)

EIA0 is what, a DE600?
Did your old TCPIP support them already? Could well be, but I don't know.
What does TCPIP>LIST COMMUNICATION_CONTROLLER tell?

Maybe someone defined the EI COMMUNICATION_CONTROLLER per hand and wrong?
Compare the EI definitions with the eg. EW

In TCPIP$CONFIG, I set that interface to IP address 10.210.54.67 (which
I've confirmed is not in use on the subnet), and the mask to
255.255.255.0. I plug this system into a hub that also has a PC plugged
in (PC's IP is 10.210.54.66).

I can ping the DS20 from the DS20 (by its name, by its IP and by its
127.0.0.1 address).

I cannot ping the PC from the DS20 or the DS20 from the PC (by IP
address). I can ping the other systems in the hub from the PC.

Have I missed a crucial NIC configuration step?

btw: Has the PC a firewall software running which prevents sending
an echo response?

Also, I know that on another 7.3 system I worked on, I had to start the
INET driver before I could even see the interfaces with TCPIP SHOW INT.

But that's not the case on this DS20. Even so, I tried starting INET
and still the pings between the PC and the DS20 all failed.

Help! What am I doing wrong or forgetting to do?

What does the ARP table tell? Any foreign addresses there? And so on
What does the routing table tell? Default route there and correct? ...
