It could, at a very least, prevent disconnections without explicit user interaction.=20 $ grep -i keepalive /etc/ssh*config /etc/ssh_config:TCPKeepAlive yes /etc/sshd_config:TCPKeepAlive yes Despite the man pages for ssh_config and sshd_config stating that it is enabled by default, I had to explicity declare it to prevent ssh=20 connections _from_ a cygwin box to the outside from dying. This was a while back, though.
