PIX IOS 7 SSH fails.

Solace — Fri, 21 Feb 2020 08:10:54 GMT

Hi,

After upgrading to IOS version 7 connecting to my PIX externally via SSH fails (Using PuTTY). I've tried changing the SSH versions allows to both SSH version 1 & 2.

The PIX logs (IP's removed):

315011: SSH session from X.X.X.X on interface outside for user "" disconnected by SSH server, reason: "Internal error" (0x00)

Any ideas?

Me too....

Oddly, this happens on a brand new Pix 515 UR PII 433 MHz, but I also have an older Pix 515 UR Pentium 200 MHz where it works fine.

Nothing terribly obvious in the configurations.

Anyone else have this problem?

I had the same problem when upgrading from 6.3(4) to 7.01.

TAC gave me the following to run:

conf t

ca zeroize rsa

ca gen rsa key 1024

ca save all

Now those commands are the old commands - when you run them v7 tells you the new commands - I jsut can't remember them off the top of my head.

Cheers

Sonny

Synchronicity!

I just thought what the hell, would recreate the keys from the CLI.

Typed in 'crypto key generate rsa' and lo and behold, back in business (phew)! Must be a bug with ASDM as the first box i configured the hostname & domain name by hand.

Thanks for your swift response and suggestions Sonny.
