Enter configuration mode; fw fw enable fw# fw# config t fw(config)# You need to have an enable password to use ssh; fw(config)# enable password. Cisco ASA SSH, Don’t Forget To Generate A Key. It looks like you need to generate an RSA key for SSH: 1 crypto key generate rsa modulus 1024. Ciscoasa(config)# crypto key generate rsa general-keys modulus 1024 noconfirm INFO: The name for the keys will be: RSA-Key Keypair generation process begin. Solved: Using GUI, ASDM, How can we generate crypto key modulus 1024? Find A Community. Buy or Renew. Find A Community. Cisco ASA – Gernerate RSA Keypair From. This solution allows remote access to the ASA whether or not a VPN tunnel is terminated. Of course, SSH is the preferred method since it is more secure than Telnet. If you have a static public IP address (does not change), you can allow SSH only from that IP address to the ASA.! Generate RSA keys crypto key generate rsa modulus 1024!

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;

We need configure SSH on a Cisco router or switch in order to access it remotely, unless we’re using an access server. The label is important, I'll tell you! In a minute why C1801(config)# crypto key generate rsa modulus 1024 label C1801 The name for the keys will be: C1801% The key modulus size is 1024 bits% Generating 1024 bit. When generating the key, you want to use a modulus of at least 1024 bits. So: crypto key generate rsa modulus 1024 (I typically do 2048) I know that's a requirement for ssh v2, but I'm not sure about ssh v1. The only other thing I can suggest is lower your ssh timeout so the sessions clear out quicker.

SecureCRT: Connection closed.

OSX/Linux: ssh_exchange_identification: Connection closed by remote host.

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!
