It also says: "if you disconnect from the Internet, your connection will be usable when you reconnect.". The same logic applies if you restart your network interfaces on the server.

I'm open to being proved wrong here, but as I've already said, only been doing this for several years now, so I'd need a counter argument to explain the mechanics of what's allowing the connection to reattach rather than "it's not possible" :)

edit: hmmm, re-reading the latter part of keep alive article I posted, it does seem to imply what your saying. So how come my SSH connections aren't nuked then? Is this just a property of TCP/IP (I'm not a networking guy so ignorant to some of the lower level stuff)

Yes, as long as both endpoints (TCP/IP stacks) keep their state it doesn't matter what stuff does between them. Interfaces being one of the things being between stacks. That is what allows for stuff like live application migration as long as you bring the TCP/IP state.

I see. Thank you :)
