OK, well, I enabled pim, robert bradley killed more traps, and I bumped the clock rate up,<br>so we basically now have the same kernel config that 3.3.8 had.<br><br>As well as had polipo try TFO by default, and update uftp to 3.7.1, and tried to<br>
config dhcpv6 appropriately for dhcpv6, and twiddle some firewall rules.<br><br>And booted it up only to see no /proc/whatever/net/igmp file once again,<br>and no 224.x.x.x in ip maddr...<br><br>It turned out the igmp entries in /proc ARE being stripped out by a<br>
openwrt patch... which I killed... so I built it again....<br><br>and walla! ip maddr shows multicast stuff and the igmp file exists.<br><br>Hopefully this will resolve the dlna issue and others.<br><br>Get it at:<br><br>

initiating uftp from the router, or vice versa, I was able to transfer<br>
multiple files around at the same time to multiple machines<br>over wifi and wired.<br><br>I've long yearned to have time to truly benchmark multicast<br>at scale, and that's why uftp has been in there so long...<br>

tons of options, and it's kind of inobvious that sending files<br>requires an interface to send on, and that the mesh interfaces<br>won't multicast...<br><br>happy multicasting. Have fun with high rates over wifi,<br>
