SSH Problem.

[ensorg]

Hi,

I'm having a problem connected to a PIX using SSH. I enabled SSH using the command "SSH 0 0 outside" and I enabled a key using the commands..

ca generate rsa key 1024
ca save all

I downloaded putty to use as my client and changed to SSH from the default telnet. But when I try to connected to the PIX I get a connection refused error message.

Can you see any problems with my configuration below? or could it be a problem with the router (ISP's) dropping the SSH traffic?

You are missing the password... type the following command:

passwd <password>

If that doesn't work then do a &quot;show ca mypubkey rsa&quot; to make sure the CA key is still configured.

Hi,

Thanks for the response, I created a password using the passwd command and did the show ca mypubkey rsa command - it shows that the key has been created, but when I attempt to connect via Putty I am getting the same error message.

Sometimes the RSA keys get corrupted. Try issuing the following on the pix, then reconnecting

ca zeroize rsa
ca generate rsa key 1024
ca save all

This will clear the rsa key you currently have, and generate another.
