RLM (was: Re: changing/setting flow control)

Don't you mean "from the console" ?

My RLM listens on port 22, but I'm unable to log in to it. I cannot find
any other way to contact the RLM. I'm wondering who can log in to that
ssh port on the RLM (but then you first need to get past the firewall).

I am able to log into the filer using ssh, via one of the normale
ethernet interfaces. Or via the serial console, for that matter.

This is on a FAS6080, by the way. Maybe other RLMs do allow access to
the command line?

I must admit I've never used the RLM. Ssh or serial console every
time. The RLM just looks like a lot of hassle for no great gains.

You all are missing out ;)

That RLM gets an IP address/Netmask/DefGW/Mailhost for IP info.
You then "ssh naroot [at] IP_of_RL"

Now, you can do things like:
cycle power on the head - just like turning the power switch at the head.
switch to the console - just like using a serial session, but over IP.

No more setting up the term servers, this give much better control....

Thanks, everyone who replied! I can now access the RLM. The thing
already had IP, but I didn't know about logging in as "naroot". Fixed
now, and indeed, it offers more control than just a serial console, and
it's faster.

Re: RLM (was: Re: changing/setting flow control) [In reply to]

For the benefit of the list, one of the other great things about the RLM is that it will often grab console logging in the event of a low-level hardware event, and write it to the 'system log' , events, or both.

More detail below. 'system log' is the command I'm talking about, from the RLM console (not system console)
