For some reason, after LOTS of idle chatter between my F21 SSH client and the server (I am assuming these are SSH application keep-alives), my F21 SSH client sends a TCP keep-alive. This is after some long time of 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
