using autossh on Fedora 35

[Ranjan Maitra]

Hi,

What is the best way to use autossh on Fedora 35?

I have been using:

autossh -M xxxx -N -L mailhub-etc hostname

Until today, I used xxxx but from today, this is not working, and I am wondering if this is because the particular xxxx is no longer an unmonitored port? I had nightly updates to F35 yesterday.

Just to be clear that

ssh -L mailhub-etc hostname

still works, so my thinking is that the issue is with the first part.

So, I tried replacing xxxx with yyyyy and this particular yyyyy does work. But I was  wondering if there was a better way than me discovering that it does not work once in a while and then trying my luck on what could be a good monitoring port.

Many thanks and best wishes,
Ranjan
