ALOM (BREAK Requested - Access Denied) (Was: LISA 2005 attendees?)

Just to be sure we're talking about the same thing:

You've got a serial cable between the Avocent and the port marked SERIAL
MGT on the back of the V210, and nothing plugged into the NET MGT port?

Unfortunately, my V210's are a few hundred miles away from me at the
moment and I have them all hooked up through the NET MGT port. (they
arrived when we were short on terminal server ports, so using the ALOM
as a one-port TS made a lot of sense at the time...)

I have not seen that, but I've only really used the NET MGT connection.

Different accounts on the ALOM can have different permissions and I
belive sending a break can be denied to an ALOM account. Did you
explicitly log in or are you just using the default login you get on the
serial port?

That's actually newer than the bits I'm currently running (1.4).

Correct.

How well do you find that the NetMGT stuff works? We're short on IPs
(sorta) so it makes more sense for us to use serial ports to manage
these boxes.

I'm using the default login, and since it only seems to be 'admin'
with full privs:

sc> usershow
Username Permissions Password
admin cuar Assigned

Ok, maybe things have changed since then. And maybe I've got it setup
that it thinks it's got the network management port setup properly.
Not sure...

Well enough that I usually don't notice it in between conserver and the
host.

Fair enough; given that ALOM still hasn't been taught to speak ssh I'd
advise putting it on a segregated MGT network where that's often less of
a concern.

(I'm wondering if the people who put the labels on the hardware were
aware of the exploits of the Midget in the "Illuminatus!" books. but I
digress).

I'll take another look at this next week when I get back into the same
building as these critters.
