Can’t Login to Your ASA via SSH or Telnet?

Posted on February 18th, 2008 in ASA, PIX, Firewall, Cisco, Security, InterNetworking by Aaron Conaway

I deployed a [tag]Cisco[/tag] [tag]ASA[/tag] at a location and couldn’t get logged in via [tag]SSH[/tag]. I would get prompted, but, no matter what username/password I put in, it would just reject me. After some digging, it turns out that I forgot this command.

aaa authentication ssh console LOCAL

When I put this in, it let me right in as expected. I have no clue what the deal was. I guess I assumed that the ASA would use the local userbase if a [tag]AAA[/tag] service wasn’t configured. I guessed wrong.

I’m sure this will apply to telnet sessions as well. I’d also bet money that equivalent [tag]PIX[/tag] OS versions do that same, so keep an eye out.
