|    TCP connections, do they survive link-la    |

      From: grahn+nntp@snipabacken.se              Assume I am on host A and have a long-lived TCP connection to host B       (like a telnet or ssh session). And then I bring my network interface       down, and up again (e.g. using Unix ifconfig). Or maybe it goes down       and there is something automagical which brings up A's wireless link       instead, with the same address.              The question is this: should I expect my TCP connection to be alive       after this?              I think I have heard that Linux and the *BSDs make this work, but that       Windows kills the TCP socket when the interface disappears from under       it. But that's a vague memory. I can experiment with Linux, but not       with all other IP stacks out there ...              BR,       /Jorgen              --        // Jorgen Grahn |
