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, or is
there a way to make it work?
