[Zhu, Binbin (Nokia - CN/Hangzhou)]

Hi,

Specifically, it worked in 
2.2.0(0.289/5/3) 2015-08-03 12:49 i686 Cygwin

But failed in 
2.2.0(0.289/5/3) 2015-08-03 12:49 i686 Cygwin

Both i686 and x86_64...

Hi,

It worked month ago, but it failed after reinstall.

1. Create shared session: ssh -vvv -nNf -o ControlMaster=yes -o ControlPath="$HOME/.ssh/ctl/%L-%r@%h:%p"  remote-host
Output in accepting new connection: 
$ debug1: multiplexing control connection
debug3: fd 5 is O_NONBLOCK
debug3: fd 5 is O_NONBLOCK
debug1: channel 1: new [mux-control]

2. Client output:
$ ssh -vvv -o ControlPath="$HOME/.ssh/ctl/%L-%r@%h:%p" remote-host
OpenSSH_7.1p1, OpenSSL 1.0.2d 9 Jul 2015

debug2: ssh_connect: needpriv 0

Could you help?
