I know i'm new to the list but i'd like to propose something for tincd daemon. I'd like to mark all sockets established by a tincd process with a mark passed as an argument in the command line. What could be the purpose of this new option? The goal of this option is to be able to have several tincd process running at the same time using the same port but using different ip. In

...* modify routing tables; * bind to any address for transparent proxying "IP_TRANSPARENT"; * set type-of-service (TOS) "IP_TOS" * clear driver statistics; * set promiscuous mode; * enabling multicasting; * use setsockopt(2) to set the following socket options: SO_DEBUG, SO_MARK, SO_PRIORITY (for a priority outside the range 0 to 6),SO_RCVBUFFORCE, and SO_SNDBUFFORCE Cheers, Michal Hlavinka

The first one is run for all incoming and outgoing TCP sockets, the second one sets up the UDP sockets. Try it out and see if it really allows you to do the mark-based routing you want. If it works, you can submit a patch or pull request. -- Met...
