Re: Raritan Dominion SX Console servers.

We have an number of the Digi CMXX boxes.  They are very nice with the ability to ssh to port 7000 to see a list of the available ports on the box, and then just hit a number to bring up that particular console.  You can also individually ssh to port 7001 for the first port, 7002 for the second, etc, but I can never remember what port something is on.  I could see this becoming an issue if you had more than one of these at a site...some overall management like Digi Connectware Manager would be needed to keep it straight.  You can also ssh right into the box to find that they are running Linux under the hood:
# uname -a
Linux digicm32 2.4.2_hhl20 #725 Mon Jan 3 17:19:07 KST 2005 ppc unknown
# df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/root.old             3963       532      3227  14% /initrd
/dev/mtdblock2           13880     13880         0 100% /
/dev/mtdblock5            1024       324       700  32% /usr2
which I think Raritan and Cyclades also do.  I was told this allows you to do neat things like syslog to a CF card and sftp that to a central server for reporting from remote sites with cron.

I like the Digi CMxx series of console servers.  Simple to use,
compact, a sane admin interface, etc.

So what are your primary issues?  Are you trying to put the console
server on your production network and secure them by using SSH to
connect from Conserver to the console?

Is there an option of setting up a private network which only the
console server uses to talk with the console servers?

I've got both Digi CM and Avocent CPS16s, and I personally want to
chuck the Avocents out, their interface is pretty ugly.  I wish I
could play with some other boxes...

Also, you might just want to poke around on Ebay for Digi and or other
vendors boxes for sale cheap.  It's not like they have alot of working
parts in them which can go wrong... and you might be able to get a
good deal that way.
