IMO it would be more elegant to send RSTs > to boths sides of the connection. Wouldn't it be possible to send packet to user space and have something else send the reset packets to both ends? I.e. use IPTables to match the packets and have a user space daemon act on what IPTables matched. (I'm speaking out of my arse here, so ignore me if I'm way off base.) Grant. . . .
