I never seen/used it myself, but it looks like as described by Joe. Joe is out of town for a week. Not sure if he is checking email. I texted Rob asking to check his email and confirm.

Fwd: Re: [internet-freedom] openWRT vs. FCC - forced firmware lockdown?

by Mitar

Hi! Some more activity on this topic. The deadline for comments was extended until October 9. BTW, have you seen this article more or less in favor of FCC rule: https://www.techdirt.com/blog/wireless/articles/20150831/07164532118/no-fcc… Also, there is a mailing list for people interested in this topic: http://lists.prplfoundation.org/cgi-bin/mailman/listinfo/fcc Mitar -------- Forwarded Message -------- From: Andrew McConachie <amcconachie(a)berkeley.edu> Subject: Re: [internet-freedom] openWRT vs. FCC - forced firmware lockdown? Hey Internet Freedomers, I wanted to provide an update on this as things have changed. The original language from the FCC that we discussed is no longer in the proposed rule change. The specific reference to DD-WRT has been removed, and it now looks like the below language is what governs this. "(i) For devices including modular transmitters which are software defined radios and use software to control the radio or other parameters subject to the Commission's rules, the description must include details of the equipment's capabilities for software modification and upgradeability, including all frequency bands, power levels, modulation types, or other modes of operation for which the device is designed to operate, whether or not the device will be initially marketed with all modes enabled. The description must state which parties will be authorized to make software changes (e.g., the grantee, wireless service providers, other authorized parties) and the software controls that are provided to prevent unauthorized parties from enabling different modes of operation. Manufacturers must describe the methods used in the device to secure the software in their application for equipment authorization and must include a high level operational description or flow diagram of the software that controls the radio frequency operating parameters. The applicant must provide an attestation that only permissible modes of operation may be selected by a user."[0] In my opinion the FCC has rightly limited their concern of software update to anything which relates to software controlled radios. The requirement for device manufacturers will be limited to showing that a software update cannot reprogram a software controlled radio to cause interference. In practice, this will most likely mean that binary drivers will be required to run OS's like OpenWRT, and manufacturers like Marvel/Avago will continue to obfuscate their hardware APIs. This is a compromise I think we're going to have to live with. Below is the comment I made to the FCC(tracking number 1jz-8kvr-4z96). " Please do not do anything to interfere with the development of OpenWRT, DD-WRT or similar alternative firmware. It is important that consumers maintain the right to change the OS of any devices they own. For the purposes of preventing spectrum interference it is necessary that software controlled radios not be easily reprogrammable. However, this requirement should in no way interfere with the legitimate right of consumers to change the general purpose OS's of their legally purchased devices. Sincerely, Andrew McConachie " Comments close on Sep 8, only 7 more days to go. Speak now or forever hold your bits. Also, if anyone knows someone at the LibrePlanet SaveWiFi wiki their page has the wrong comment deadline.[1] Their page says October 9, but the FCC deadline is September 8.

New server colo suggestion, + SF node offer

by Pete Forsyth

Hello Meshers, I'd like to introduce Jon, a former colleague at Wikimedia (he ran the office network), my generous web host, and an all around good free culture guy. After talking with Marc, I asked Jon about options for server colocation. This is not my realm,so I offer you his suggestion verbatim...hope this is useful. Also, should we set him up with a node in SF? Jon has the chops to troubleshoot stuff on his own, and it would be cool to have a node on that side of the bay...perhaps a baby step toward that elusive transbay link? Regardless, I would suggest Jon add his home to the node map -- except it seems to be offline?? http://map.sudomesh.org/ If responding, please keep in mind Jon is not on the email list, and CC as appropriate. -Pete [[User:Peteforsyth]] on the wiki On Thu, Sep 3, 2015 at 12:08 PM, Jon Davis <jon(a)snowulf.com> wrote: <snip> > #3 - I have not.

Adrian Chadd, who is on the sudomesh mailing list, is the one who I believe implemented TDMA in FreeBSD.

Can someone, please, donate $ to buy Acoustic Caulk to repair the Ballroom south wall? (Picts)

by danarauz＠gmail.com

Hello All, Could someone, please, donate money to buy 10 large tubes of acoustic caulk? We need $80. You don't have to buy it yourself, but if you prefer, according to our more experienced Omni member sheet rock installer (Joe), the acoustic caulk that we should get is the one made by OSI. It costs about $8 each. WHAT FOR? To complete the the sheet rock installation at the Ballroom south wall. WHEN DO YOU NEED IT FOR? We need it by this Saturday, so we can continue working on it during our next work party. HAVE PHOTOS?

Re: [Mesh] [sudo-discuss] Can someone please donate Cat6 Shielded cable?

by max b

Hey Charley, You're more than welcome to donate money (or time) if that's more up your alley. Also, if you want to donate UTP cat6, we'll take that as well. We use a bunch of ethernet cable both at the omni and for other installations, so we can always use more. If you're feeling really generous, we can really use shielded outdoor cat5 and cat6 for installing antennas. Don't worry - no matter what kind of ethernet cabling you feel like donating, we can almost certainly find a use for it :) As for the questions you've outlined: First thing: shielded cable This isn't actually an ethernet run. It's dsl lines + phone lines running over cat copper wires. As such, it's my understanding that it's more sensitive to EMI disturbance. Additionally, it's much better to err on the safe side as we'll only want to string this once and the entire network communications infrastructure depends on the dsl signal that passes through this line. As for needing shielded mating jacks, we have plenty of grounded rj-45 connectors and with whatever other scenarios, it's pretty easy to ensure that they're grounded. We're not talking about our entire network infrastructure, we're just talking about this one cable run. Second thing: hand termination We're using an EZ RJ-45 crimper, which makes the process fairly straightforward. We have spools of other types of ethernet cables and have done runs throughout the building. Also - we'll be breaking out these pairs anyhow, so most of this is fairly non standard types of termination which are much easier than rj-45 disconnects. Daniel, let us know if I missed anything here?
