- 2 hours ago Ip domain-name rtp.cisco.com!- Generate an SSH key to be used with SSH. Crypto key generate rsa ip ssh time-out 60 ip ssh authentication-retries 2. At this point, the show crypto key mypubkey rsa command must show the generated key. After you add the SSH configuration, test your ability to access the router from the PC and UNIX station.
- Define AAA lists for ssh: ASA(config)#aaa authentication ssh console LOCAL. Generate crypto key pair to use with SSH server: ASA(config)#domain-name grandmetric.labs ASA(config)#crypto key generate rsa general-keys modulus 1024. In addition you can set the allowed sources, and define on which interface ssh will be allowed.
- Mar 04, 2008 So, I purchased a Cisco ASA 5505 to build a VPN Tunnel from a remote office to my main office. Really simple to do, when you are using Easy VPN. Anyway, I wanted to turn on SSH. So, I enabled SSH on the ASA, and tried to access it: apaxson@netutil $ ssh -l username.
Problem
I’ve lost count of the number of times this has happened to me! Most of my colleagues prefer to use the ASDM for remote management, but if (like me) you work at command line, then sometimes people <ahem> forget to generate the RSA keypair when deploying a firewall. Then even if SSH access and AAA is setup correctly, you still can’t get in via SSH. Instead you see the following;
RoyalTS and RoyalTSX: ssh_exchange_identification: Connection closed by remote host.
PuTTY: PuTTY Fatal Error: Server unexpectedly closed network connection.

Now at command line you can fix this with a ‘Crypto Key Generate RSA Modulus 2048‘ command, but you can’t get to command line only ASDM.
Solution
On older versions of the ASDM you could generate the keypair in the Identification Certificates section (well you still can but only if you are also generating a certificate request file). So, as we are command line warriors, lets use the ASDM’s command line!
What if you generate the same private key finder. Tools > Command Line Interface > Multiple Line
