If you have recently tried to setup SSH access on a new ASA, it might not have worked the way you wanted. That is because the RSA keys need to be generated first. To do that:
crypto key generate rsa
asa(config)# crypto key generate rsa
INFO: The name for the keys will be:
Keypair generation process begin. Please wait…
INFO: The name for the keys will be:
Keypair generation process begin. Please wait…
And then configure SSH to be allowed from the inside interface:
ssh 0.0.0.0 0.0.0.0 inside
Now you will be able to login using the default username and password of pix/cisco, Or you can configure AAA and setup your own usernames. Doing this will make the pix username no longer work for SSH.
First, a username needs to be created:
username cisco password c1sc0
And then configure AAA:
aaa authentication ssh console LOCAL
Done!


ran into this very issue and I tried to apply your fix. however i still get denied. I get the key but it doesn’t allow me to login. Also I tried to zeroize the key first. Noting. Does it require a reboot.
I ran into this very issue as well but I had been trying everything I could find in the ASDM admin to get it working first. I think the only difference is that I created my user in ASDM first and made sure they had full management access. Thanks!
Hi there would you mind letting me know which web host you’re using? I’ve loaded your blog in 3 different browsers and I must say this blog loads a lot quicker then most. Can you suggest a good hosting provider at a reasonable price? Thanks a lot, I appreciate it!
Joeann,
I am hosting the site on a “cloud” server that I run. That server is hosted by Rackspace out of Chicago. I have serveral servers with them and have been very happy with the service and performance.
