Sun RSC console

Currently I have configured a few portmasters connected to our serial ports
with conserver controlling our consoles. We have been recently expanding
and upgrading to Sun 280R systems in our Data Center. They all come with
the RSC port that allows remote console access. I like the added features
of the RSC port over serial, but I don't like how it logs. I would also
like to keep a consistent face on how to connect to all of our servers.

Rather then connecting up more servers to the portmaster (we are almost at
the point of needing yet another one), I would like to let conserver use the
RSC network port. Does anyone have some of these configurations?

This one is remarkably easy, actually. If you think of the RSC card as a
single-port terminal server on tcp/23, you get something like this in your
config file:

somehost:!somehost-rsc [at] conserver-hos:23:&.log:10m

You need a DNS entry for 'somehost-rsc' mapping to the IP of the RSC card.
Everything else should be obvious.

Hope this helps.

RE: Sun RSC console [In reply to]

But you would need to have a login and password for the RSC port. Then pass
the commands for console. I just have to find the time to write a script
that will connect and pass the correct commands to the rsc.

Example:
telnet somehost-rsc
Connected to somehost-rsc
Escape character is '^]'.

RSC version 2.1 (somehost-rsc)

Please login: conuser
Please Enter password:

That'd be more elegant than my solution, I suppose. We just create
a low-privileged RSC user and leave it logged in and set to 'console'
mode. It's pretty rare that the low-privilege user would get
logged out or escaped back to the RSC, so this isn't a hassle at all.
