[...] Whether this is a good solution or not depends on what the perceived problem is. If the issue is file sharers tying up bandwidth to the Internet, this is an excellent approach. It will limit all heavy users indiscriminately, though, so someone who (say) does a network-based upgrade of his or her Linux host (an "apt-get upgrade" in Debian terms, or the equivalent for other distros) or downloads ISO images of Linux-distro CDs will be limited in the same way as someone doing a lot of music downloads. If the issue is preventing use of the Internet connection to download unauthorized copies of copyrighted materials, then this approach is probably not sufficiently targeted to accomplish what the original poster requested. It has the "false positive" problem in spades. If the issue is inhibiting on-LAN exchanges of unauthorized copies of copyrighted materials ... well in that case, this entire discussion's focus on solutions at the router level is completely misplaced. If that is the perceived problem (in a college setting, I can easily imagine it being so, especially of the LAN provides service to dorm rooms), the solution needs to involve a heavy dose of on-LAN traffic sniffing. Even talking about that approach requires less abstraction from a particular LAN implementation then we have had here so far. Whatever the case, this idea does have the advantage, relative to other approaches that have been discussed in this thread, of being based on Linux kernel capabilities that actually exist, not extensions that "should be easy" but that, in fact, have not been done, or (I suspect) even looked at closely by anyone with the technical expertise actually to implement them. BTW, lest I be misinterpreted, I am not trying to present an argument for or against actually doing any particular kind of content filtering. I am only trying to think aloud about the technical issues involved in implementing solutions to various desires for control of network use. - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
