SSH ISSUE

[cristicks]

Hello, I have a C2621xm router connected to a C3500 24 port switch which is connected to a PC . I'm trying to SSH from the switch to the router. I get successful pings to and from all 3 devices .

Using puTTy ,I created a domain name, generated keys and created a username to be able to set up the SSH connection . Although, when I right click on the console session top left hand corner and choose new session, I choose SSH and then I type in the correct ip address of the router I'm trying to SSH into and I get a new console screen , but it is unresponsive. It won't allow me to type anything nor do anything at all. I have done this using the same equipment in the past. What might I be doing wrong this time???

I tried factory resetting the switch, rebooting everything and reconfiguring from scratch but that didn't work. I would appreciate any help I can get. Thanks!

PS. it allows me to telnet from the pc into the switch and router. Not sure if that helps.

Hello,

are you using ssh version 2 ?

If you generate the key, make sure you use 1024 (512 is the default)...

I don't think I'm using version 2. Should I be? I did however have it set to 1024 bit encrypt. Same outcome.

thanks for replying.

Hi

if you have created the keys, domain, username and password,  you can try executing these command lines:

conf t

no aaa new-model

ip ssh version 2

line vty 0 15
transport input ssh

Hope it is useful

:-)

Thanks for your response. I tried those commands but when I get to ip ssh version 2 it says "invalid input detected at ....and points to the "v" in Version 2.

Do you have "login local" configured on the router's VTY lines?

I did not. Works now. Thanks very much for the help.
