SSH V2

Unanswered Question
Sep 14th, 2009

Hi,

I have 6509 switch with the IOS "s72033-advipservicesk9_wan-mz.122-33.SXH2a.bin"

I have configured the SSH but I can't login with ssh into this swtich and when I gave 'sh ssh' I get the following warning;

hq-ndc-core01#sh ssh

%No SSHv1 server connections running.

%No SSHv2 server connections running.

Can someone advise what is the reason (wheather IOS is not supported, in that case why I'm able to configure all ssh related commands..?)

Appreciate a quick response.

I have this problem too.

Hi JG,

thanks for your response. Infact I have alreadt went through the url u sent. But there is no luck. I doubt about the code we are using which is "s72033-advipservicesk9_wan-mz.122-33.SXH2a.bin". ??

FYI, I did not enable debug on ssh as it was on production network.
