Subject: TCP connection passing
Date: Thu, 31 Oct 2002 00:02:49 -0300 [thread overview]
Message-ID: <20021031000249.A20233@almesberger.net> (raw)
Here's something creepy for Halloween: a dirty little hack that
allows you to pass TCP endpoints across hosts, across reboots,
etc.
http://www.almesberger.net/tcpcp/tcpcp-0.tar.gz
(Includes a patch for 2.5.45, a bit of user space, and plenty of
documentation of its shortcomings. The patch is a bit deceptive:
in order to make timestamps work properly, more invasive changes
are needed.)
I got the idea for this hack while listening to Fabio Olive
Leite's talk about load-balancing at Linux-Kongress, but
besides that, he's not to blame for it.
The implementation is a proof of concept, which is quite sloppy
with timestamps, MSS, window, etc., and don't even look at what
it does to congestion control ...
Anyway, it seems to work, and it's fun to play with.
- Werner
