SOL = serial over lan. No concept of a screen.
If you want to look at what's on the text console,
cat /dev/vcs
Or use conman (which is available as a package) to record and

It works now (in a rudimentary way!). Thanks guys, for the tips. I
found the ipmitool in a CentOS repo. I gave up on comping my own.
/usr/bin/ip
I wanted to get some opinions about if watchdog timers are a good idea
or not. I came across watchdogs again when reading through my IPMI
manual. In principle it sounds neat: If the system hangs then get it
to reboot after, say, 5 minutes automatically. But, in practice, maybe
it is a terrible idea

Because some hardware bugs are scary, and could/would have profound

Well, it's not just for HPC anymore, all
there sometime!...shouldn't this be an enterprise-level concern not
just HPC? I mean what if you have 200 Windows machines and wanted to
turn hyperthreading off in the BIOS.
first, you don't really depend solely on the bios for HT. next,
those 200 boxes are probably spread out, and possibly not

Hi Rahul,
[of course, maybe some of my settings are naiive or erronous; feel
free to correct me]
OK
I can pretty much remote monitor logs, stats, remote power reset etc.
The only two things I cannot:
(1) Can't do a Serial-on-LAN (SOL); My Dell server needs a special
card (read more money)

Are you asking for latency or throughput ? For latency, it depends on

Any clue what this might be? How can I get the lanplus interface

sounds like your version of ipmitool is compiled without lanplus

Is this a driver issue or do
