Question
Which two steps are required before SSH can be enabled on a Cisco router?
Solution
To enable SSH on a Cisco router, you need to follow these two steps:
-
Configure the Hostname and Domain Name: SSH requires a hostname and a domain name to generate the necessary RSA key pair for encryption and decryption. You can set these using the commands "hostname [name]" and "ip domain-name [name]".
-
Generate the RSA Key Pair: After setting the hostname and domain name, you can generate the RSA key pair. This is done using the command "crypto key generate rsa". You will be prompted to enter the modulus size. A larger modulus size will be more secure, but will take longer to generate and use more CPU resources. A modulus size of 1024 is typically sufficient for most purposes.
