This router implements Secure Shell (SSH) Server, a feature that enables an SSH
client to make a secure, encrypted connection to a Cisco router. This connection
provides functionality similar to that of an inbound Telnet connection, but which
provides strong encryption to be used with Cisco IOS software authentication.
The SSH server in Cisco IOS software will work with publicly and commercially
available SSH clients. This feature is disabled if the router is not using an IPsec DES
or 3DES Cisco IOS release, and if the SSH branch of the Additional Tasks tree does
not appear.
SSH uses an RSA cryptographic key to encrypt data traveling between the router
and the SSH client. Generating the RSA key in this window enables SSH
communication between the router and the SSH clients.
Crypto key is not set on this device
Appears if there is no cryptographic key configured for the device. If there is no
key configured, you can enter a modulus size and generate a key.
