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.

| All Linux and macOS distributions come installed with a terminal application that can be used for SSH access to the login nodes. - Linux users have different terminals available depending on which distribution and window manager they use (for example: GNOME Terminal in GNOME; Konsole in KDE).
Consult your Linux distribution's documentation for details on how to load a terminal. - On macOS you can use the Terminal application, which is located in the Utilities folder within the Applications folder.
Another popular terminal application for MacOS is iTerm2, which needs to be installed separately. |

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>@<hostname> <generic-hostname>
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. |

Terminal 1 shows an example of a user logging in to one of Setonix's "login" nodes, where the specific name of the node that has been assigned to the connection can be seen in the default prompt, as well as the running of the 'hostname' command. (Note that the complete "MotD" (Message of the Day) content has been truncated in the example output.)
