[HELP] Does Cisco 2611 Router only support SSH v.1???

This is my "show version"

Cisco Internetwork Operating System Software
IOS (tm) C2600 Software (C2600-IK9O3S3-M), Version 12.3(26), RELEASE SOFTWARE (f c2)

whenever I type "ip ssh ?" the "version" command does not pop up. I am able to use ssh, but I'm assuming it's version 1. Does it have to do with an incompatibility with the router or the IOS image I am using?

I'm really just curious. I'm using this router in a lab environment and I can do ssh v2 on my CAT 2950 so it's not a big deal. However I still would like to know. I'd appreciate any responses.

I don't think any image will do SSHv2 just SSHv1.99. It really does not matter what version of SSH you are running on any Cisco box as long as you use ACLs to protect the router. We a small number of legacy CPE that's still in production that running the v1.99 today. Nothing is turned up in our network without an ACL to protect the management of the device so the SSH version isn't of much concern.

SSH V1.99 is version 2. SSH v1.5 is version 1. Just go with it...
I'm pretty sure I have a couple of 2600's wth a 12.4 IPServices IOS that will do SSHv2, but I need to check so fo rnow I'll stand to be corrected on that.

I guess it's too much trouble to call v1.99 v2. I often wonder what the thought process among engineers at the design level.

"v1.99" is v1 and v2. It MUST say "v1.XX" or v1 clients will refuse to connect -- unsupported version. v2 clients know "v1.99" means it'll do v2 as well.

As I recall, 12.3 does not support v2. Check www.cisco.com/go/fn for your specific image to see what it will support.

Tell you right now that 12.3.26 for 2600s do not support SSHv2. I know cuz I used to run 12.3.26GD train on
an old 2600, and my biggest wish was to upgrade to SSHv2. According to FeatureNavigator, I was looking at
least a 12.4T train, which you can only load on the XM series of the 2600s.
