Hello, Are there libraries for Mac OS X (10.5) that allow packet manipulation, just like Linux's netfilter library does? Specifically, I would like to write a program that should be able to process every packet in the system before it gets `written' on the wire. According to this page: http://www.netfilter.org/documentation/HOWTO/netfilter-hacking-HOWTO-3.html, my program should be able to be hooked at stage [4]. I searched a lot, but in vain. Thanks, -- Vimal -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
