EVEN MORE Fun with Server Core 2012 R2

And finally, to finish off my Windows Server Core 2012 R2, I install Cygwin!  Advice from the web says preemptively open port 22 for OpenSSHd.

netsh advfirewall firewall add rule name="SSHd" dir=in action=allow protocol=TCP localport=22

Now, download the Cygwin installer:

$client = new-object System.Net.WebClient

$client.DownloadFile( "http://www.cygwin.com/setup-x86_64.exe","c:\windows\temp\setup-x86_64.exe" )

Now, run the installer:

c:\windows\temp\setup-x86_64.exe

Don't forget to configure OpenSShd (in Cygwin Bash):

$ ssh-host-config -y
$ cygrunsrv -S sshd
$ ssh-keygen -t rsa

Assuming you added lots of nice Cygwin utilities, you now have a very useful server.  ;-)
