Next steps:

Create a policy to grant access to the application

In general, rules are ordered in importance, with the lowest number (1) having the highest priority. If you have rules that overlap; for example, an SSH Range Application rule and Network Range Application rule, you would place the SSH Range Application rule above the Network Range rule.

Verify that the Atmos Agent is Open and Online

To verify that the Atmos Agent is open and online:

  1. Use an SSH client such as Terminal or Putty to SSH to the server.
  2. Use the same username as configured in the User Portal settings as shown in the following example:
    SSH [email protected][server address]
  3. Go to the Insights screen to see that the user has connected to the SSH Range application and which server that the user connected to.
