Specifying ciphers, MACs, or KEX algorithms

You can control which MACs and ciphers are used by a particular SSH listener.

To view the MACs and ciphers used by an SSH listener:

  1. From the top menu, select Server > Listeners. The Listeners page opens.
  2. Click the IP address of the listener you want to open. The Edit Listener page opens.

    At the bottom of the page, click Edit SSH Settings. The Listener Encryption Settings (SSH) page opens.

To add a cipher, MAC, or KEX algorithm to an SSH listener:
  1. Click Add below the cipher, MAC, or KEX algorithm list.
  2. Select the cipher, MAC, or KEX algorithm that you want to add.
    Note: If nothing appears in the list, all available ciphers, MACs, or KEX algorithms are already assigned to the SSH listener.
  3. Click Save.

To remove a cipher, MAC, or KEX algorithm from an SSH listener:

  1. Select the radio button next to the name of the cipher, MAC, or KEX algorithm you want to remove.
  2. Click Remove. The page reloads with the selected cipher, MAC, or KEX algorithm removed from the list.
