I have the exact error on my Jenkins 2.7.4 server connecting to Windows Server 2012 R2 with OpenSSH-Win64 with public key only authentication. I have successfully tested connection to other Windows machines with the exact version of OpenSSH-Win64 with public key only authentication, which gave me a CMD prompt.
Settings changed in sshd_config are: PubkeyAuthentication yes PasswordAuthentication no I installed openssh via: choco install win32-openssh -y Then i tried the x86 version of the same OpenSSH, and yet the error was the same. According to this post: https://wiki.jenkins-ci.org/display/JENKINS/SSH+slaves+and+Cygwin > Cygwin comes with OpenSSH server, which works well with SSH Slaves plugin > <https://wiki.jenkins-ci.org/display/JENKINS/SSH+Slaves+plugin>. This is > one of the recommended way of controlling Windows slaves from Jenkins, if > you don't mind the added effort of installing Cygwin and sshd > <http://www.noah.org/ssh/cygwin-sshd.html>. > I have yet to succeed, but i will post back soon. -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
