For some reason, after LOTS of idle chatter between my F21 SSH client

the client NOT sending an SSH idle packet.
As soon as the server receives this TCP keep-alive, it sends a TCP RST
and that 'breaks the pipe'.
So what in the client determines the rate of SSH keep-alives and for how
long inactive?
Look at ServerAliveCountMax and ServerAliveInterval in
/etc/ssh/ssh_config and ~/.ssh/config, however as Gordon has mentioned,
it smells like an IP conflict and one way to sort it is "arping" the
remote host.
There is no ~/.ssh/config and neither of these variables are in the
/etc/ssh/ssh_config, so they are whatever the defaults are.
These servers are on my internal subnets. I know exactly what boxes are
on which subnets and what their addresses are. But I checked anyway,
and there are no IP conflicts.
thank you for your help
