I read from the manual that the key pair will be used for SSH but just wonder does the command 'crypto key generate rsa' is necessary to enable SSH on ASA?
I can access to my firewall via SSH but when I checked in the configuration on ASA firewall by 'show run', I didn't see this command by the way. Anyone can guide me how to check if my ASA already be enabled 'crypto key generate rsa' ?
Thank you all very much for reply.
Yes, it is necessary to generate the rsa key pair for SSH access.
Here is the command to check the keypair in your ASA:
show crypto key mypubkey rsa
Hope that helps.
