I just learned about ssh multiplexing and tried to set it up (Cygwin client
to Debian server), but it fails to work and each attempt leaves a zombie ssh
process.
According to the ssh -vvv debug output, authentication is successful but
then fails during setup of the control master with
mm_receive_fd: no message header
mux_master_process_new_session: failed to receive fd 0 from client
I found a StackOverflow post from over a decade ago indicating the problem
is that Cygwin doesn't support file descriptor passing via unix-domain
sockets. https://stackoverflow.com/questions/20959792
Is it still true that ssh multiplexing is not available in Cygwin,
Yes.
or is there a way to make it work?
Not without descriptor passing, sorry.

'Tis a pity... but I do understand there are some things *nix can do
that are just not possible to accomplish or emulate in the Windows domain.
Thanks for the reply.
