--- Comment #1 from Damien Miller <djm at mindrot.org> ---
If you are using an interactive session, then ctrl-C can't kill the
local ssh process (think about it for a moment and you'll realise why).
For interactive sessions you should use the Disconnect escape sequence
described in the "ESCAPE CHARACTERS" section of "man ssh".

Usually "<enter>~." unless you have overridden it.

Created attachment 2181

Cleanup channels when using ControlMaster and ~.

Also note that there is a known bug when using ControlMaster (ie mux
mode) where the escape sequence ~. does not work in the ControlMaster
client.  If this is what you're seeing please try the attached patch.
