Configure remote login (SSH)
By enabling remote login, you allow users from outside the local area network to start an SSH session and access settings on the controller.
For SANtricity versions 11.74 and later, you can also configure multifactor authorization (MFA) by requiring users to enter an SSH key and/or SSH password. For SANtricity versions 11.73 and earlier, this feature does not include an option for multifactor authorization with SSH keys and passwords.

-
Select Hardware.
-
If the graphic shows the drives, click the Controllers & Components tab.
The graphic changes to show the controllers instead of the drives.
-
Click the controller for which you want to configure remote login.
The controller’s context menu appears.
-
Select Configure remote login (SSH). (For SANtricity versions 11.73 and earlier, this menu item is Change remote login.)
The dialog box opens for enabling remote login.
-
Select the Enable remote login checkbox.
This setting provides remote login with three options for authorization:
-
Password only. For this option, you are done and can click Save. If you have a duplex system, you can enable remote login on the second controller by following the previous steps.
-
Either SSH key or password. For this option, proceed to the next step.
-
Both password and SSH key. For this option, select the Require authorized public key and password for remote login checkbox and proceed to the next step.
-
-
Populate the Authorized public key field. This field contains a list of authorized public keys, in the format of the OpenSSH authorized_keys file.
When populating the Authorized public key field, be aware of the following guidelines:
-
The Authorized public key field applies to both controllers and only needs to be configured on the first controller.
-
The authorized_keys file should contain only one key per line. Lines starting with # and empty lines are ignored. For more information about the file format, see Configuring Authorized Keys for OpenSSH.
-
An authorized_keys file should look similar to the following example:
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDJlG20rYTk4ok+xFjkPHYp/R0LfJqEYDLXA5AJ49w3DvAWLrUg+1CpNq76WSqmQBmoG9jgbcAB5ABGdswdeMQZHilJcu29iJ3OKKv6SlCulAj1tHymwtbdhPuipd2wIDAQAB
-
-
When you’re done, click Save.
-
For duplex systems, you can enable remote login on the second controller by following the steps above. If you are configuring the option for both a password and SSH key, be sure to select the Require authorized public key and password for remote login checkbox again.
-
After technical support is finished troubleshooting, you can disable remote login by returning to the Configure Remote Login dialog box and de-selecting the Enable remote login checkbox. If remote login is enabled on a second controller, a confirmation dialog opens and allows you to disable remote login on the second one as well.
Disabling remote login terminates any current SSH sessions and rejects any new login requests.
