Use of Powershell terminal or Windows Command Prompt
The Microsoft Windows operating system now has in-built SSH client support. It may first need to be enabled as an optional feature in the settings. When using the client at the Windows command prompt or PowerShell, the correct MAC option must also be provided:
$ ssh -m hmac-sha2-512 [options] <username>@<generic-hostname>
Replace <username> with the username of your Pawsey account, and <generic-hostname> with one of the hostnames listed in Table 1 in Connecting to a Supercomputer.
Alternatively, the line MACs hmac-sha2-512 can be added to a file called config that can be created in the C:\Users\<username>\.ssh directory in Windows to avoid providing this option every time.
It does not currently support X forwarding of graphical interfaces, for which use of the MobaXterm client is recommended.
MobaXterm
A popular alternative client for Windows users is MobaXterm, which includes an integrated X server with SSH client to run graphical applications on supercomputers. When downloading MobaXterm Home Edition, please refer to the End User Licence Agreement.

Basic SSH Connection using MobaXterm
MobaXterm allows for a terminal session to be used for basic SSH connection as per Logging in with ssh page.

To be able to start a local terminal (since version 8), you need to download and install the CygUtils.plugin package from http://mobaxterm.mobatek.net/plugins.html. Move the downloaded file into the same directory as the MobaXterm executable, for example, "C:\Program Files (x86)\Mobatek\MobaXterm Personal Edition", and then restart MobaXterm. |

Putty
PuTTY is a free client and available for all recent versions of Windows. It can be downloaded and installed following the instructions on the PuTTY download page, provided you have the appropriate permissions for your computer. Otherwise, you may need to ask a system administrator to complete the installation for you.
