    SSH Server The secure shell (SSH) server allows remote peers to access the router over a secure TCP connection using a suitable SSH client. The SSH server provides a Telnet-like interface and secure file transfer capability. SSH uses a number of keys during a session. The host keys are used for authentication purposes. Keys unique to each SSH session are also generated and are used for encryption/authentication purposes.
