One of the key differences between SSH1 and SSH2 is that SSH2 lets you have multiple channels per connection whereas SSH1 only lets you have one. The following URL corroberates:
My question is... why doesn't the Cisco IOS allow multiple channels?
I'd like to be able to send a bunch of exec-type channel requests (see rfc4254#section-6.5 for details) per connection but it would appear that I cannot since the Cisco IOS device closes the connection after my first channel request has been fulfilled.
Is there a work around? Do new Cisco devices fix this?
