How to enable administration of Cisco ASA ssh instead of telnet?

Hi,

You need these atleast

telnet

ssh version 2

ssh

ASA(config)# crypto key generate rsa modulus 1024

In the above you specify the source network where you are going to connect to the ASA. The source interface is also mentioned. This is the interface behind which the users are located. It might typically be "inside" and/or "outside". You can enter multiple statements if you are managing from multiple different networks.

For example

telnet 10.10.10.0 255.255.255.0 inside

ssh 10.10.10.0 255.255.255.0 inside

ssh 1.1.1.1 255.255.255.255 outside

In addition to this you can naturally configure local AAA on the ASA so you can use a username/password to authenticate.

Hope this helps
