Message-ID: <20020810115843.B6225-100000@phoenix.vh.laserfence.net> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG I've recently been facing the problem that people with these P2P clients are eating up major bandwidth. For this reason I've implemented dummynet to try and curb them abit. The problem now is that I keep getting complaints that "my kazaa doesn't work at all" I've been watching activity graphs, and it seems that when I remove bandwidth limiting rules, it works fine, and chews up most of the link. When the rules are implemented again, everything else works fine, but these P2P things stop working almost entirely (just a stray out of sequence ACK here and there) It would seem that these things don't respond well to having themselves kept on a tight leash. I don't find that a problem, personally I'd firewall off every one of them, but most people want the functionality for some reason. Is there any reason KaZaa/other Fastrack/p2p clients would respond badly to artificial bandwidth limiting like dummynet, has any one had this problem before, and does anyone know of a way to fix it, without letting them use all the bandwidth they want, that is?
