Ssh with Pix

dcristoni — Fri, 21 Feb 2020 06:13:00 GMT

I have a Cisco PIx 506,i have tried to connect with Ssh but the Pix deny my connection.

I can't connect to Ssh from the remote ip address a.b.c.d

My config is:

ssh a.b.c.d 255.255.255.255 outside.

My Cisco Pix don't have 3Des.

Thak you

Hi, you will need either des or 3des to get ssh access. You can get a des license from Cisco for free if you need from.....

You will need a valid CCO login to get to that url.

After you get that key here is a document to get ssh configured on the PIX...

The document shows how to do local and AAA authentication.

Hope that helps and good luck....

DES is probably enabled in your PIX, but you need to use SSH protocol version 2. If your SSH client doesn't support version 2, download PuTTY from

This worked on my PIX 515.
