Sensor# ssh generate-key

Chapter 3 Setting Up the Sensor

Configuring SSH

Use the ssh generate-keycommand to change the SSH server host key. The displayed fingerprint matches the one displayed in the remote SSH client in future connections with this sensor if the remote client is using SSH.

Note The sensor only supports RSA keys. Peers that communicate with IPS need to support RSA keys; otherwise, the connection is not established.

To generate a new SSH server host key, follow these steps:

Step 1 Log in to the CLI using an account with administrator privileges.

Step 2 Generate the new server host key.

RSA Bubble Babble: xucot-sapaf-sufiz-duriv-rigud-kezol-tupif-buvih-zokap-sohoz-kixox sensor#

Caution The new key replaces the existing key, which requires you to update the known hosts tables on remote systems with the new host key so that future connections succeed. You can update the known hosts tables on remote systems using the ssh host-keycommand.

Step 3 Display the current SSH server host key. The sensor displays the RSA1 (SSHv1) and the RSA (SSHv2) keys.
