   Hi @Kreisfahrer,

   Strange, the changes have been small and should not cause this problem.

   Could you please include a minimal working example and the resulting traceback?

   Some details.
   pytest session with xdist connection is started on:
   Windows Server 2012r2 with Python 3.6.7 (64 bit)
   pytest-3.6.0

   command:
   -d --tx 'ssh=user@host//chdir=some-folder' --max-slave-restart=5 --rsyncdir .
   Targeted host(the only one) is windows 10 os.
   ssh server details:
   OpenSSH_for_Windows_7.6p1, LibreSSL 2.6.4
   It can be some specific issue with OpenSSH for windows. I didn't try it on any linux yet. But it was working perfectly fine with execnet <1,7.0 which breaks with

   I'm getting a similar error from my Jenkin's server environment. Execnet on the server's workspace was version 1.7.1. Reverting to execnet 1.6.1 worked.
