Introduction

Keypairs are used for access to our Linux hosts via SSH. Using Arcus portal, you can generate a new key pair or import an existing public key.

Creating a SSH Key Pair

  1. Click on the username to open a window where you can see preferences, support, and a log out button.

User Profile 2. Click on Preferences.

Preferences

The preferences will have a popup window with three different tabs, permitting the following:

  • Set Default Language on the current browser
  • Create/Upload a public SSH key to be injected into new Linux VMs
  • Change the current login password (local users only – no Active Directory support)

Click on SSH tab.
