Determining the pid/subj of a packet is notoriously difficult/impossible in netfilter so let's drop that; with proper policy/rules you should be able to match proto/port with a given process so this shouldn't be that critical. The source/destination addresses and proto/port (assuming IP) should be easy enough. All right, now that we've got the "must" items down, are their any "should" items we want? -- paul moore www.paul-moore.com -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
