This is a guide to installing ssh in Cygwin. It assumes that you have alread successfully installed Cygwin in MS Windows
The ssh in Cygwin that we are referring to is different than the SSH in MS Windows. The SSH in MS Windows is a GUI program that provides some of the capabilities of ssh. The ssh in Cygwin is an ssh that would be installed on a Linux system and includes all the features of ssh, including scp.
You should review Updating Cygwin before you ssh in Cygwin.
The ssh package is in the category Net in a package called openssh. Go through the process of updating Cygwin, select the category Net, and inside that select the package openssh. Then go through the rest of the updating process.
Start up a Cygwin bash shell. A bash shell is the shell that many Linux systems use. You can do this by selecting the Cygwin icon or from the Start menu.
In the bash shell type the command:
ssh username@172.16.112.48
It should prompt you for your password. If successful you will be logged into 172.16.112.48.
