Hi, After having a lot of help of Grant Taylor in order to analyze if I was able to achieve my idea using the available iptables features, and getting as result the fact that I had to develop my own kernel module. I'm writing to this list because my question is related to the linux kernel programing. I would like to pass parameters to the kernel module in run time from user space. These parameters could be IP address and MAC. Somebody know how I can do this?? I was thinking about passing this parameters thorough a sysctl syscall or using /proc filesystem, but I beleave that this is not the correct way. Also I was taking a look to iptables source code and analyzing the source code of iptables and libiptc lib, but I could not find any clue how to these ones change the kernel parameters. Could you pleas help me??? thanks! -- 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
