NO! We're using UDP - UDP packets have no acknowledgment. TCP would behave like you describe, but UDP senders have no way of knowing that there's a problem. Freenet itself acknowledges packets, and that's part of the rate limiting, which obviously has some bugs. Not reading the packets will work for a while, but when packets are read and ack'd the senders will burst again, not knowing there's a limit. The only solution is to fix the limiter bugs, which is tough for a project with so few developers. _______________________________________________ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe
