SSH Timeouts

[Jonathan Hutchins]

I'm looking for other people who are having trouble maintaining idle SSH 
sessions.

Recently RoadRunner replaced our router at one location, and since then idle 
sessions lock up in three to five minutes.  As far as I know, there was no 
change on any of the systems involved.  SSH clients and daemons are largely 
set to default configurations.  Sessions within the site do not lock up, and 
sessions between other sites still behave as expected.

I AM NOT LOOKING FOR HELP READING THE SSH MAN PAGES!  I am aware that there 
might be solutions in using UDP keepalive signals and other options, but what 
I want to do is confirm what's happened so I identify the reason and return 
things to their previous function.

I am looking for other people who have EXPERIENCED this change, or who have 
heard about it happening to someone else.  I want to identify what we may 
have in common with other sites where this has happened.

Thanks,
Jonathan
