First post! Hi, all. I have been prototyping a new community wireless network down in Nicaragua. The terrain is hilly and well suited for meshy solutions...
So, anyway, I had just got olsr working on both dd-wrt and openwrt and was a little dissatisfied with the results - when I read about babel. The RFC looks very good, as did the paper describing the performance tests, and I especially liked babel's size in memory - on my ubquity power station 2s the (old) binary is 1.6MB in size (compared to 6MB+ for olsr, admittedly with the web interface turned on). I also very much want to manage this network via ipv6, so babel is a big win there, too, as olsr requires I run two daemons to do both protocols. So I'm considering converting my existing prototypes over to babel and ahcp to see what happens. I've read all about babel that I could find and a few months back on this mailing list, and haven't found the answers to: Open questions 1) Is anyone maintaining an openwrt repository that implements later versions of babeld and AHCP? The version of babel in the current (RC2) release candidate for openwrt is ancient and doesn't interoperate with the current release. (I think. It gives an error about the versioning of the packet) The other pre-built version out there on the web is back at .91. I'm willing to build openwrt from scratch (and I think I have to, because most of my existing routers only have 4MB of flash and things like dnsmasq and udhcp can go in this configuration) ... but I do find the prospect somewhat scary. I have a server co-located with isc that I could host it on if anyone was interested. Given that I can't easily run current babel right now (will it work with a 2.4.37 kernel?) My experiments are limited so far. I'm cloning the openwrt repo right now, tho.... 2) I saw patches for tcpdump. Is anyone working on a dissector for wireshark? 3) Is radvd still necessary in a babel/ahcp environment? 4) What radios are people using with babel? I've been looking over ubquity's new routers and thinking I would use those (8MB flash, 32MB ram, MIMO) in the future, but I'm certainly open to more hackable designs... 5) I do love the web interface to olsr. I can imagine something similar could be built for babel... But I don't really see the point of http existing inside the daemon.... 6) Is there a AHCP hook to hook into name service updates? Autoconfiguration is well and good but nsupdat-ing dns names is better... 7) What happens in the case of IPv4 multicast (for example, squid ICP multicast)? Thanks for any help in advance. I will continue my reading and compiling.... -- Dave Taht http://the-edge.blogspot.com _______________________________________________ Babel-users mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/babel-users
