Remote Console Connections to Alpha servers

tobyjug — Tue, 25 Nov 2008 01:00:50 GMT

All out Alpha consoles are connected to DS90TLs. How do I remote connect to the console via the decserver / port number ?
We are losing our console monitoring software so I want to know if I can still connect to the console remotely

It may depend on how the terminal servers are
configured. Around here, I have some system
consoles connected to a DECserver (200/MC),
and I defined a service for each of them.
From a VMS system, I can get a list of the
services available, so:

alp $ latcp show servi

Service Name Status Identification
---------------- ----------- -------------------------------------------------
ALP Available COMPAQ Professional Workstation XP1000, VMS V7.3-
2 (Saint Paul)
DY_CONSOLE Available DY Console
GIMP_CONSOLE Available GIMP Console
IT_CONSOLE Available IT Console
MODEM Available Modem
SPARE_CONSOLE Available Spare Console
WIMP_CONSOLE Available WIMP Console

Or, from the terminal server:

Local> show servi

Service Name Status Identification

ALP Available COMPAQ Professional Workstation XP1000, VMS V7.
ALP2 Unknown COMPAQ Professional Workstation XP1000, VMS V8.
DY_CONSOLE Available DY Console
GIMP_CONSOLE Available GIMP Console
IT Unknown HP zx2000 (900MHz/1.5MB), VMS V8.3-1H1 (Saint
IT_CONSOLE Available IT Console
MODEM Available Modem
SPARE_CONSOLE Available Spare Console
URTX Unknown HP Tru64 UNIX V5.1B LAT SERVICE
WIMP_CONSOLE Available WIMP Console

And I can connect to one of them from a
VMS system, so:

alp $ set host /lat IT_CONSOLE
%LAT-S-CONNECTED, session to IT_CONSOLE on node SP2 established
%LAT-I-TODISCON, type ^\ to disconnect the session
cli>

I can also connect to one of then from the
DECserver itself:

Local> connect it_console
Local -010- Session 1 to IT_CONSOLE on node SP2 established

cli>

Many things are possible, but I don't know
how to connect to a port without first
defining a service.

You do not need specific software beyond the terminal server.

You can set it up to connect using lat service in a lan environment, or just use telnet.

For my own Decserver (DS90M) I have set up a predicable telnet port for each line.
Here are the "Local>" commands I used:

CHANGE INTERNET SUBNET MASK 255.255.255.0
CHANGE INTERNET ADDRESS 192.168.1.140
CHANGE TELNET LISTENER 23 PORT CONSOLE
CHANGE LOGIN PASSWORD "secret"
:
CHANGE port 3 access remote
CHANGE TELNET LISTENER 2003 PORTS 3
CHANGE TELNET LISTENER 2003 CONNECTIONS ENABLED
CHANGE port 4 access remote
CHANGE TELNET LISTENER 2004 PORTS 4
CHANGE TELNET LISTENER 2004 CONNECTIONS ENABLED

Good luck,
Hein

just an add-on to heins note - for telnet make sure default protocol is set to "any" or "telnet".

good luck

Thanks for all your help.
The response has been great, and, of course,
it worked.

Thank again
