Hello guys! Is there some easy way to bind the COM2 port to the OPA2 console on my Alphaserver DS25? I'm running AXPVMS 8.3

I'd like to be able to run some commands without having to connect a keyboard and mouse to the computer. Also I'd like to keep my settings on the COM1 port, since it's connected to the RMC.

Hi,

the COM2 port (marked <=> 2) at the back of a DS25 (upper DB9 connector) should be TTA0:

Okay, here is some info for you guys who are interested in connecting a terminal to the Alphaserver DS25. The COM1 port is connected to TTB0 on the system. To access this console, you have to wait until you can login on the OPA0 (the standard console). After that you should wait about 10 seconds, then press enter. To access the RMC console, press Escape two times followed by RMC. ( ^]^] RMC ). The RMC console lets you monitor fan speeds, zone temperatures, and even system power on and off.

Good luck guys smiley

Hi,

the naming of the COM1 and COM2 ports inside OpenVMS may depend on the console settings (SERIAL or GRAPHICS) and/or whether you're running DECwindows (SYSGEN parameter WINDOW_SYSTEM).

The DS25, that I'm currently working on has:

COM1 = OPA0:
COM2 = TTA0:

with WINDOW_SYSTEM=0 and CONSOLE = SERIAL

Eisner was upgraded to the current Multinet Release. As part of that a new host key was generated. The old key was incompatible with newer Linux.

ssh to eisner is now giving (on linux) "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!" , Has the server key in fact changed ?

HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.
