Quickstart/Connect
Contents
A VPN is required to connect to Viper off campus or from the university guest's wifi. Connections from Eduroam don't require VPN.
- If you have a managed PC then VPN access is already provided.
- If you have your own computer and want VPN access you can request access through the Support Portal.
Connection Method 1 - Web browser
Viper can be accessed through a browser using the Viper Ondemand service which allows you to run jobs without using an SSH terminal
Connection Method 2 - SSH
If you wish to use an SSH terminal follow the instructions below.
If this is your first time connecting please note that you may see an error message in .XAuthority, this is normal and you can ignore it.
Connection Method 2 - Connecting with a Windows PC
An application that allows SSH connections must be installed to connect to Viper from a Windows PC. We recommend MobaXterm.
Installing MobaXterm
