Just pushed out version 1.0rc1 of the Ruby WinRM gem. With it you can run a Windows cmd shell or powershell scripts from Linux or MacOS. This version brings a lot of new features including Krb5 authentication and message encryption for Active Directory connected hosts. Instead of the WinRM service configuration that was once needed with the prior gem you can now simply do a ‘winrm quickconfig’ on the Windows node and you’re off. gem install winrm –version=1.0.0rc1 or check it out on github: http://bit.ly/ruby_winrm
