Among other things, they have my ssh public key in them, and are keyed to local dns, they rely on the babel protocol to route and mesh together, although they do come up presently on a fixed ip address that needs to be changed, instead of relying on AHCP for their IPs and dns. All of quagga (including OSPF) IS built, it's just that babel is the defaul= t. In working with this build and test deployment I exposed some problems with memory usage in codel and the ath9k driver. Quagga will get OOM-killed under heavy loads, such as RTP and UDP flooding across multiple diffserv values, on the 2HP boxes in AP mode. The p2p backbone (nanostation M5s) has never crashed on me. This points long term towards developing a "mfq_codel", which would have one qdisc and *one* set of buffers that controls all four hardware queues. However, try as I might, I haven't wrapped my head around how to merge the code for sch_mq and sch_fq_codel, in a way that would work. (?) Aside from that it's working rather well, and the hacks I have in place now to reduce skb size seem to help a lot. Now that the memory problems are mostly beaten I will be doing a respin and re-deployment towards the end of the month. If I can build something a little more generic and easy to deploy on ubnt for others, I will do so, getting to where all this code runs well in 32MB is rather important to me. Let me know.
