[[I asked this yesterday on -questions, probably the wrong list]]

If a server has one interface to the Internet and another interface to a
switch connecting to a few other servers, it seems TCP's MSL value might
reasonably be set a lot lower on the private interface.

I'm specifically thinking of a lot of short MySQL connections(*) between
the
servers on the private LAN. The average number of MySQL client connections
in TIME_WAIT will be proportional to MSL. And, while the circumstances
under which a long MSL would help anything are unimaginable on the LAN,
they are not on the Internet.

So can net.inet.tcp.msl be set per interface?

(*) Or similar: Sphinx, memcached, perhaps.
