SSH v2 or SSH v1.99

[cdcjim2877]

Hi,

I would like to know if the following IOS version only supports ssh v.1.99 or if it supports true ssh v.2.

The IOS is 12.4(13r)T

Our Nessus scans continue to kick back the vulnerability due to the 1.99 option which allows version 1 ssh connections. I believe we may have purchased the incorrect IOS image for the router.

If not, how do I allow the router to only accept version 2 connections?

ip ssh version 2.0 at the CLI continues to report back as v1.99

thanks,

Jim

Jim,

I think U have made the correct selection of IOS,

We do have the same IOS Version 12.4(13r)T, and this support SSH V2.

R01#sh ssh

514 2.0 IN aes256-cbc hmac-sha1 Session started

514 2.0 OUT aes256-cbc hmac-sha1 Session started

%No SSHv1 server connections running.

R01#sh ip ssh

SSH Enabled - version 1.99
