Configuration file TCPKeepAlive option does not work reliably
Hi!
There are configuration knobs (TCPKeepAlive) to enable/disable the use of TCP keepalives both in the ssh client and server. Unfortunately some UNIX systems default to SO_KEEPALIVE=on and some to =off. This may even be settable on a per host basis (OpenBSD default net.inet.tcp.always_keepalive=1 ???).
For the TCPKeepAlive configuration knob I would like to propose changes along the lines
