Hi

 This is probably GNS3, correct?

If GNS3 dont waste time on this router. Just add another router and repeat the process which is really simple and you know already.

aaa new-model

ip domain-names 'domain'

hostname 'hostname

crypto key generate rsa 'key'

ip ssh version 2

 I just had the same problem here. Tried many times in one router with no success and then the other I got  it to work with the same process.

ciscp#sh ssh
Connection Version Mode Encryption Hmac State Username
0 2.0 IN aes256-cbc hmac-sha1 Keys exchanged -
0 2.0 OUT aes256-cbc hmac-sha1 Keys exchanged -
%No SSHv1 server connections running.

Hi, doing this in packet tracer on a 2910

have had this work before but just can't get it to work today

[Flavio Miranda]

For Packet Tracer, even though the router shows :

%No SSHv2 server connections running.

%No SSHv1 server connections running.

Goes to a machine and fire up an SSH session. I got this same situation as well.

After tried to access, the service came up

myrouter(config)#do show ss

Connection Version Mode Encryption Hmac State Username

323 1.99 IN aes128-cbc hmac-sha1 Session Started flavio

323 1.99 OUT aes128-cbc hmac-sha1 Session Started flavio

%No SSHv1 server connections running.

try to ssh device after correct process you did. it will work even though it says server is not running.
