Again, the stumper was related to the Verizon connection and udhcpc, and that is a real bastard of a problem to help with remotely. I was having trouble enough trying to get tcpdump to provide useful data - as I understand it, it won't listen to a port before it is up, and it is the DHCP handshake that I care about. Lots of quick juggling of cables before software timed out. The tasks following that would have involved SSL and OpenVPN, and probably porting a couple of apps. The barriers seemed far too high, especially for a heterodox solution when a "just like all the other machines" solution seems to work. The only real problem is that the distro image is bigger, and it takes much longer to write a CF card than the tiny squashfs OpenWRT image does. For simpler setups doing what OpenWRT does best, then of course that is the right way to go for PTP. In fact, if you someday want to try out a solution to the Verizon DHCP Problem, bring a CF card by and we will try it. I can give you the MAC address of my WAN port off the list. But if Verizon FIOS is not needed for any PTP nodes right away, you can safely defer that problem. The "Scientific ALIX" process is going well, mostly since it is an almost direct copy of something working (I would not want to try it with a non-X86, small RAM/Flash machine). In fact, I mentioned what I was doing on the Scientific Linux mailing list, and I've already gotten emails from a few of them, wanting to copy the setup for scientific experiments. With a solar panel, one of those laptop extender batteries, and a daytime-only radio in the miniPCI slot, the ALIX makes a great remote data taking and massaging system, and with all the scientific and mathematical additions to Scientific Linux, that is an easy platform to develop on. With a couple of high gain antennas, it could be miles from the grid, or possibly even connect through multiple hops in a mesh, given ALIX repeater boards with two miniPCI slots. BTW, this might be something to talk to the Humaninet people about. I imagine the ALIX/OpenWRT combo would be really handy in a mesh system in the field, and could be made more theft-resistant than a PC or laptop-based solution.
