Am I right in saying following ?
A deamon say ssh will be listening on port 22. when a new connection is requested by the client, it will be authenticated and a new connection gets establihed with some port say 1025. And ssh will continue to listen on 22 for new connections.
If I am correct then in my machine I observed following connections are establised to ssh port 22, As per my understanding connection should be established on a different port other than 22.
