Allow router to be on ssh1 or ssh2 version

[Gideon Goddard]

Hello,

All is in the question ! :)
Can a router adjust it SSH version wheter the client is in SSH1 or SSH2 ?

I have look over this command :

R1(config)#ip ssh version ?
  <1-2>  Protocol version

But the ssh version is forced in SSH1 or SSH2, the SSH2 can't be automatiquely downgrade in 1 if the client is in SSH1..

Do you understand my problem ?

Have you got any ideas to solve it ?

Thanks :)

SSH version 1 is completely outdated and should not be used any more. All you should allow is version 2. But if you want to allow both (probably only valid if you build a system for a historic museum), then you just can leave this command out of your config. Then both versions are allowed and whatever the client uses to connect to the router, that version is used.
