the unix philosophy is "do one thing and do it well". the shell is the
traditional place to handle glue problems like this. e.g., if only one
of your servers needs to be fwknop'd first, something like this:

#!/bin/sh
test "$1" == sekrit.server && fwknop ...
/usr/bin/ssh $*

fill in the server and the fwknop params, name it "ssh", and put it
somewhere ahead of /usr/bin in your PATH.
