If you want to use a AAA server for authentication instead of the local database, we recommend also configuring local authentication To use SSH, you must configure AAA authentication using the aaa authentication ssh console LOCAL command then define a local user by entering the username command. You can no longer connect to the ASA using SSH with the pix or asa username and the login password. (8.4 and later) The SSH default username is no longer supported. Time to ensure all changes are applied correctly. Resources being changed, you should make changes in one SSH session at a However, because configuration commands might obtain locks on The ASA allows a maximum of 5 concurrent SSH connections perĬontext/single mode, with a maximum of 100 connections divided among allĬontexts. See Configure Management Access Over a VPN Tunnel. Only exception to this rule is through a VPN connection. Is located on the outside interface, you can only initiate a management connection directly to the outside interface. SSH access to an interface other than the one from which you entered the ASA is not supported. To configure SSH access according to this section.
To access the ASA interface for SSH access, you do not also need an access rule allowing the host IP address. To identify the client IP addresses and define a user allowed to connect to the ASA using SSH, perform the following steps.
