POLL: How do you feel about HamWAN network having shared control of the microwave modem @ your location?
by Bart Kus 28 Feb '13

28 Feb '13

Hello, Keeping the network and all client devices correctly configured is no easy feat. These are complicated devices with 100s of settings, which will need to change in coordinated ways over time. To ensure correct operation, it would make sense for the HamWAN network to push updates and change settings on end-user modems. Almost all ISPs run this way already. The difference is you can still login + control your device, but any setting changes you make which make the device non-compliant in ways HamWAN cares about would be automatically overridden with a config update from the network. If the network can't control and repair your device settings, you would lose authorization onto the network until the settings are fixed. I see this shared administration model as the only one that's feasible in keeping a reliable network running. Please let me know if you are OK with it, if you object to it, or if you have a better idea. Thanks, --Bart

Clarification on client node routing (this means your home / EOC /etc)
by Bart Kus 28 Feb '13

28 Feb '13

There appears to be confusion about what client sites will look like. I have had the Client Node Routing <https://www.hamwan.org/t/tiki-index.php?page=Client+Node+Routing&structure=…> page up for a while, but it did not contain a clear pictographic view, nor a thorough textual description. I've now spent a little time to draw up a clear graphical representation of what to expect at your site. Just hit up that page to see. Your local router and wireless access point are staying, as is your Internet modem. The newly added HamWAN microwave modem + router will simply plug into the LAN side of your network. From a routing perspective, the HamWAN modem will announce routes to your main router via RIP /most likely/ (see below). These are subnets which are accessible via the microwave network and the packets for those subnets should be sent to the microwave modem. Default gateway /should/ (see below) stay as your main ISP. If you have received subnet routing services from HamWAN (ie: you have your own subnet which is announced into the rest of the HamWAN network) then you'll configure your LAN devices with your subnet's IPs. The open problems in this design are: 1) Asymmetric reply traffic when requests come into your HamWAN subnet from Internet IPs. The reply packets will attempt to leave via your ISP since it's your default gateway. We may have to do some policy routing on the main router to mitigate this, or multinet any network devices which want to talk out both networks. To be engineered. 2) DNS queries need to work for at least the HamWAN.net domain despite a total Internet failure (of both your local ISP and HamWAN's Internet links). DNS queries for regular Internet domains should be undisturbed during normal operation. HamWAN should not request any control over user routers beyond the HamWAN modem + router device. On the HamWAN modem + router device, users need to be free to define their own firewall rules and set other settings which do not conflict with HamWAN access policy. --Bart

Where does one buy these V-Bolt clamps cheaply?
by Bart Kus 28 Feb '13

28 Feb '13

I'm thinking about $2.50/ea would be nice. Muffler clamps are NOT adequate. Muffler clamps have 2 semi-circle contact surfaces, and if the pipe is slightly smaller than the clamp, this creates a 2-point contact which causes rocking action. Gross. The nice toothed and V-angled designs here are the bomb. Soup for scale. :) --Bart

Component Engineering: Ethernet Switch - 8 port
by Bart Kus 28 Feb '13

28 Feb '13

Dear Ben-Jammin', So you might recall our recent discussion where you weighed in favor of putting "real" switches into the cell sites to tie the radios together. My major pushback to you was the price of a typical Cisco/etc switch. Well, I've updated the "Ethernet Switch - 8 port <https://www.hamwan.org/t/tiki-index.php?page=Ethernet+Switch+-+8+port&struc…>" page with 3 new alternatives! They're a miniscule amount of money more than the D-Link smart switch, and are in fact full blown RouterOS routers. They also feature 2 more ports (10 total) than the 8-port requirement, but the catch is only 5 of the ports are GigE. This might be OK since all the 5SHPn radios are 100Mbit only. The GigE requirement was for future-proofing only. The other super nice thing is they can do MPLS-TE and preserve QoS. This might simplify the network structure a lot by moving routing off of the modems and into these routers. Instead of 7 linked routers at a busy cell site, we'd have 1. The routing tables get a lot easier. These routers also have more routing horsepower than what's in the modems. Especially the $105 model, which features a faster CPU and twice the RAM. 2 of the 3 are also rack-mountable, which might be a good thing in most sites. Finally, the idea of using a single OS for all networking is appealing. No need for fragmented administrator education, and all the gear is designed to work together. Let me know what you think. I'm kinda psyched about this approach. I ordered a RB2011UAS-2HnD-IN for my personal home use to replace my AP+router here. We'll see how it works out here. --Bart RB2011UAS2HnDIN

Any auto parts store should have a selection. I also would try McLendon's Hardward. When you tighen they enough they will bite. Daniel Stevens, KL7WM In a message dated 2/27/2013 7:25:25 P.M.

Just a reminder we'll be meeting in 30 minutes. Below is the agendar. I have new items around DNR, Cogent, HE.net, and a possible collaboration with IntermountainInternetIncorporated. Also, sector shielding material was just picked up, we'll see if it improves isolation at all. --Bart On 2/25/2013 2:13 PM, me(a)bartk.us wrote: > 0) Rob will update us on rotor control software progress. > > ----- Reply message ----- > From: "Bart Kus" <me(a)bartk.us> > To: "Puget Sound Data Ring" <psdr(a)hamwan.org> > Subject: [HamWAN PSDR] Agenda for tomorrow's meeting (Feb 26, 2013) > Date: Mon, Feb 25, 2013 2:05 pm > > > Hello, > > 1) We'll know results of vote on sector antenna purchase.
