This is a simple tutorial how to run the OpenSSH SSHD server on Windows using Cygwin.

SSH is typically used to log into a remote machine and execute commands, but it also supports tunneling, forwarding arbitrary TCP ports and X11 connections; it can transfer files using the associated SFTP or SCP protocols. SSH uses the client-server protocol.

OpenSSH (SSH1 and SSH2 protocol) with Cygwin can run on Windows, which can be either built from source or installed as a Cygwin native package.

Here we go…

First, we need to install the following Cygwin packages (cygrunsrv and openssh)

Admin --> cygrunsrv
Net --> openssh

Next, open a new bash shell window and run the SSH configure stuff.

ssh-host-config -y

This step will create necessary configuration files, a privilege separation user and necessary directories.

When prompted with “CYGWIN=” type for following:

tty ntsec

Now you are ready to start the service

cygrunsrv -S sshd

Give a try to connect to your ssh server (localhost) with your favorite ssh client, such as PuTTY, Xshell, etc.

That’s it and gud lak!
