down a bunch of consoles

Hi,

I browsed the documentation once again - unsuccessfully
is there a way to down a particular set of consoles?
I only found the syntax to down *all* consoles

cheers

RE: down a bunch of consoles [In reply to]

From the client (communicating with any individual host), you can use
[ctrl]+[e], [c], [d] to "down" that port.

Or, if you know you need to stop a bunch of consoles for a while (so
that someone can use reverse-TCP to get to those ports, maybe for using
a Sun Jumpstart-type tool), you can edit the conserver.cf file, and
simply comment out the lines associated with those ports, and then -HUP
the main Conserver process. (And you can re-enable them later by editing
the file and deleting that lead-# comment marker, and then re-HUP-ing
the main process again).

Are there other considerations you need which make either of these two
methods unworkable?

yeah I used that in an expect script to down many at once. Not very reliable

yeah sure but I dont like it because:

1) I like to keep my conserver.cf files in sync between my 6 conservers
which means I have a cron to do that.

2) I believe it's a maintenance task, which should be handled by 'console'
it'd be kind of cool to be able to 'console -u' to check nobody's
connected to some consoles, then 'console --down <list of consoles>'.
I mean there's a mechanism for downing a console. Why not one for many?

thanks for your time

RE: RE: down a bunch of consoles [In reply to]

I'm not sure why I might use that type of feature. (I prefer to log
all of the time, versus defaulting a bunch to "down"...I only have one
device that spews ~120-160 MB/Day, which I normally 'down' unless I
suspect I'm having trouble with the device. It is the debug port on a
Cisco Firewall Service module, one of a redundant pair...I keep the
'other' FWSM debug port UP, since it's idle, unless something goes wrong
and the two blades failover. If the other logfile is starting to grow, I
know I need to go find out what forced the failover.)

Re: down a bunch of consoles [In reply to]

The reason I needed to do this (for the record) is due to an ILOM bug
on Sun X4500 boxes, where the SOL feature could compromize the host
OS . Thus I changed the conserver config to ondemand. However this did
not down the consoles so I had to do it manually

cheers
