That would work, yes. Keep in mind that you do not strictly need to
request ports right now, because we do not use a firewall yet (which
is what we'll use to control port access).
But, since we are planning to introduce it again (we had it on our
old server, combined with a complete management infrastructure we
created for it), it is in any case important to file a request, so
that we know which ports should be granted to users, so that you
don't experience downtime when we do it.

IP addresses and ports are listed at:
But ports used on Mire are not listed there, so you can simply
make sure you're not intending to use a reserved port by doing
the following on Mire:
netstat -nl | grep yourPort

Default, that is, no need for specific nice value.

You'd run it as:
run-in-pagsh interch nice -n <NUM> command...

Nothing for now. We have a plan of implementing a script that'd be
taking care of runaway processes (processor- or memory-wise), but
so far it hasn't really been done. (If you have a suggestion how
the logic should work, feel free to add comments).
