Crypto Key Generate Rsa Asa

  1. Crypto key generate rsa general-keys label tokenkey1 storage usbtoken0: The following example specifies the redundancy keyword: Router(config)# crypto key generate rsa label MYKEYS redundancy. The name for the keys will be: MYKEYS Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys.
  2. Mar 30, 2018  crypto key generate rsa mod 2048. Ssh timeout 30. Ssh version 2. Ssh publicip mask outside. Ssh privatesubnet mask inside. I can ssh from inside but not from outside. When trying from outside, I just get a timeout. I have tried debugging ssh and I don't get any events. I've also set logging to debug, and I don't see any connections from the.
  3. With this command we define domain-name to be used when generating crypto keys. ASA(config)#crypto key generate rsa label cisco modulus 1024 with this command we create crypto keys on asa, naming it 'cisco' and also defining key size with modulus '1024'.
  4. Sep 06, 2014  ASA(config)# crypto key generate rsa modulus 1024 INFO: The name for the keys will be: Keypair generation process begin. Step 5: Now specify only particular hosts or network to connect to the device using SSH.

Problem

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.

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.

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!
