problem with ssh access on asa

[Diego Maciel Gomes]

Hello All,

I have a problem with my ssh access.

I have two interfaces, 172.17.5.250 = Outside, security Level 0

                                10.11.3.2 = Inside, security Level 1

I can access by ssh using Outside

I can not access by ssh using Inside. I receive this message in my prompt:

ssh user@10.11.3.2

Selected cipher type <unknown> not supported by server.

I tried with ssh -1 and ssh -2. Not works.

I have ssh allowed for this source network. SSH version 1&2.

I tried:

ASA(config)#crypto key zeroize rsa

Issue this command in order to generate the new key:

ASA(config)# crypto key generate rsa modulus 1024

But no success

Cisco 8.2(12)2

Thanks

Hi Jullio...

Follow..

FW(config)# crypto key zeroize rsa
WARNING: All RSA keys will be removed.
WARNING: All device digital certificates issued using these keys will also be removed.

Do you really want to remove these keys? [yes/no]: yes

and now? generate new?

I generated... but, no way

Hello Diego,

Do you still get the same log from the client?

What logs are being showed by the ASA?

Regards,

Julio
