Configure SSH Key Authentication

The Nodegrid platform allows use of SSH keys for authorization. The feature is often used to allow automation systems to gain secure access without a password. It works well with direct Shell access and users who want to use SSH keys for a local home directory. This feature is available for all local, LDAP, AD, and TACACS+ users. Radius users cannot use SSH keys for authentication.

Configure SSH Key Authorization

1. Go to Security :: Authorization.
2. In the Group column, click on a name.
3. On the group's Profile sub-tab, in Startup application menu:
   1. Select Shell radio button (gives group members default shell access, and not CLI access, on connection via SSH). 
   2. Click Save.
4. Go to Security :: Local Accounts.
5. Create a local user and add to the new group.

The SSH key can be used for authentication. The default SSH tools can copy the SSH key to the Nodegrid device (i.e., SSH-copy-id).
