O.T.: How to make an idle connection persist

I have a workaround that I use when I'm at conferences where they seem
to care about inactivity on their network connections.

I launch a ping something like this:

ping -i 61 [address] &

I've found the not quite once a minute ping keeps my connections alive

Just a thought. hth.
