Hi Folks,
Someone out there will know the answer to my ignorant query ...
Suppose I have an up-and-running internet connection via my ISP. So I telnet into a remote host (e.g. nessie.mcc.ac.uk) and establish a login-session. So far so good.
Next, for DSL reasons, the internet connection is interrupted (the router re-syncs). Shortly afterwards, it is re-established again.
But now, I have lost contact with the login session.
My question is: What is the mechanism (or perhaps absence of mechanism) leading to losing the contact?
Or, turning the question on its head, what is it that keeps my link with the remote host alive so long as the internet connection stays up?
The naive version of the question: If my packets can find their way to my login to nessie before the line drops, and nessie's can find their way back to my telnet, how come they can't continue to do so after the line drops and is re-estiblished?
I hope people understand what I'm asking -- I'll try better if you don't!
Thanks, and best wishes to all, Ted.
