2960x ssh denied

I have setup ssh on several switches, but I am about to be defeated by the 2960X series.

Previously I have set it up using aaa model as per documentation, but hasn't helped.  I am now also trying another method without aaa model and still coming up short.

If anyone is able to provide any direction that would be fantastic.  I have already had to recover the password once and I am copying and pasting so I know I am typing the passwords in correctly

Here are some details.

The switch must be configured with

- domain name
- Hostname
- Crypto key generate RSA (1024 or +)
- Authentication retries

Please keep me posted if changing the version it works. Could you please provide the error message?

Hi,

Try to verify the ssh version: 

show ip ssh

to change  to ver 2:  

conf t
ip ssh version 2

Thank Julio.  ip domain-name and then crypto commands are what fixed it.

I thing I must of done something out of order and generated the keys before setting the domain name.

You are welcome, Good to know that is working  

Have a great day  :-)

You don't need a domain name if you configure SSH correctly:
