NETGEAR 8800 Chassis Switch CLI Manual An authentication key must be generated before the switch can accept incoming SSH2 sessions. This can be done automatically by the switch, or you can enter a previously generated key. If you elect to have the key generated, the key generation process can take up to ten minutes, and cannot be canceled after it has started. Once the key has been generated, you should save your configuration to preserve the key. To use a key that has been previously created, use the pregenerated keyword. Use the show ssh2 private-key command to list and copy the previously generated key. Then use the configure ssh2 key {pregenerated} command where "pregenerated" represents the key that you paste. The key generation process generates the SSH2 private host key. The SSH2 public host key is derived from the private host key, and is automatically transmitted to the SSH2 client at the beginning of an SSH2 session. To view the status of SSH2 on the switch, use the show management command. The show management command displays information about the switch including the enable/disable state for SSH2 sessions, whether a valid key is present, and the TCP port and virtual router that is being used. Example The following command generates an authentication key for the SSH2 session: configure ssh2 key The command responds with the following messages: WARNING: Generating new server host key This will take approximately 10 minutes and cannot be canceled. Continue? (y/n) If you respond yes, the command begins the process. To configure an SSH2 session using a previously generated key, use the following command: configure ssh2 key pregenerated Enter the previously-generated key (you can copy and paste it from the saved configuration file; a part of the key pattern is similar to 2d:2d:2d:2d:20:42:45:47:). configure sshd2 user-key add user configure sshd2 user-key add user Description Associates a user to a key. Syntax Description key_name Specifies the name of the public key. Chapter 15. Security Commands | 583
