Cannot SSH into ASA - ssh_exchange_identification: Connection closed by remote host

I usually write quiet a bit but I figured I would keep track of these small error messages also. So here it goes .. last week I ran across an issue on one of the ASAs. Here is the error message.

"ssh_exchange_identification: Connection closed by remote host"

How to fix it?

Telnet or console into the ASA and type this in the global config mode.

ASA(config)#crypto key generate rsa modules 1024

Save the config (wr).

That should resolve your issue.

Many more articles to come so ....
