[Cerowrt-devel] Wicked OT: 240.0.0.0/4 netblock

Sorry for distracting you from important things, but I have a question for people more knowledgeable about routing than I am... There's a person on the OpenWrt forum who is asking about using the 240.0.0.0/4 netblock for some (undefined) purpose. (If you're terminally curious, or need another r

[Cerowrt-devel] fq_codel is SEVEN years old today...

[Cerowrt-devel] OT: Netflix vs 6in4 from HE.net

to Bloat & CeroWrt folks: This is a little OT for either of these lists, but I figured there are plenty of experts here, and I would be delighted to get your thoughts. I just tried to view a Netflix movie and got a F7111-5059 error message. This prevented the video from playing. (As recently as

[Cerowrt-devel] Which mDNS package for modern OpenWrt

Can anyone give advice about the best mDNS package to install these days? There seem to be several contenders: mdnsutils, avahi, olsrd-mod-mdns, and umdns... Thanks. Rich ___ Cerowrt-devel mailing list Cerowrt-devel@lists.bufferbloat.net https://lists

[Cerowrt-devel] fq_codel is now EIGHT years old...

A quick test of 3.8.6-3 on my WNDR3800 looked good. I was able to execute my scripts for setting up the config the way I like and for obtaining a 6in4 address through Hurricane Electric (see the wiki for the scripts). There was a peculiar behavior with wireless immediately after configuring the

Folks, Good news from the (limited) testing that I do. I installed 3.8.8-4 on my WNDR3800 without incident. I also ran the two configuration scripts in the wiki to set the configuration to set the timezone, put a password on my wireless and set up the IPv6 tunnel. Thanks to Dave and Toke for a

This is indeed a cool hack. I was astonished for a moment, because it was a bedrock belief that you can't send pings from Javascript. And in fact, that is still true. Apenwarr's code sends short HTTP queries of the format shown below to each of two hosts: http://gstatic.com/generate_204 http:
