When working within a Windows environment, there are alternative solutions to connecting to Pawsey's supercomputing resources. Some recommended software include Powershell terminal, MobaXterm, PuTTY and Cygwin.

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.

If you do not have administrative rights on your Windows machine, opt for the portable edition. If you do have admin rights, you can choose the "Installer edition" (recommended).

Double-click the downloaded Microsoft Installer file (.msi), and the Windows wizard will automatically guide you through the installation process.

Make sure to check whether Windows Firewall hasn't blocked any features of this program after installation.

Recommended Settings for MobaXterm

Once installed, start MobaXterm and provide the Pawsey recommended the SSH settings as follows:

Select Settings → Configuration from the menu.

Click the Enable graphical SSH-browser option to disable. If selected, this would create an unnecessary graphical connection to the remote host.
Leave X11-Forwarding enabled. The -X flag for the SSH command will not be required when if X-11 forwarding is enabled.

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.

Cygwin

Cygwin provides a Linux environment within Windows and can also be used to log in into Pawsey systems. It is a port of many applications to Windows, including ssh and X, and is available from the following link: http://www.cygwin.com
