Reverse SSH abort issue

We have configured reverse SSH on a 2911 using an HWIC-16a. Telnet works just fine but when attempting to ssh (SSH - l 2010 3750-2 x.x.x.x) there is an error 'connection to 3750-2 aborted: error status 28'


Has anyone seen this before and is there something I need in the config to let the SSH pass?


Any help is appreciated

Has ssh been configured on 3750-2 to accept connections?

Hi Reza, Yes SSH is

Hi Reza,


Yes SSH is configured on the 3750-02 to accept ssh. 


It seems like the 2911 isn't letting the connection establish. If we have the TTY line connected to the 3750-02 or disconnected from 3750-02 we receive the same error. I turned on ssh debugging and the message was:


SSH CLIENTO: protocol version exchange failure (code = 28)

We managed to get the reverse

We managed to get the reverse SSH to work, we were specifying the incorrect user name. We had it working on 15.1 and updated to 15.2(4)m6a and now it does not work. it is saying connection refused by remote host. Were there changes made between 15.1 and 15.2 that would make us need to change some settings or configurations?
