No equals sign, actually. "TCPKeepAlive yes".
However, it's actually "ServerAliveInterval 5" (or such) that you
actually need. Flipping on the "TCPKeepAlive" boolean just enables the
_capability_, but the default frequency of keepalive messages, if you
do nothing about "ServerAliveInterval", is "never".
