Odd DNS Issue
by lleachii＠aol.com 11 Oct '14

All, I'm wondering if anyone else has seen this issue. I'm running BIND version 9.9.5 at 44.60.44.3. I just recently upgraded from 9.8 because I thought it would solve a very weird issue that I'm experiencing. I allow all to to lookup 44.in-addr.arpa and ampr.org; and it works. BUT, some reverse records always time out. So far, I have tested the following IP addresses which have PTR records, but do not produce results: 44.102.1.1 44.102.1.2 44.108.1.1 44.108.1.2 44.108.1.3 44.60.44.1 44.60.44.2 44.60.44.3 44.60.44.6 44.60.44.7 The only pattern that I've discovered when a lookup times out, is that the fourth octet is always less than 10. I've checked the system log, and there is no denial for the DSN query. I was wondering if anyone had ideas/suggestions. Thanks and 73, Lynwood KB3VWG

Well I know this obviously, but we did get a 180 degree sector up on a broadcast tower, so I have a bunch of newbies to microwave and networking in general to deal with. The consensus is to probably use the BBHN firmware as that is what the Emcomm and not so tech guys will have a liking to. So overall I don't think adding that kind of support to a ham rolled firmware is a bad idea if someone out there had the urge to try and figure it out. A few years back Ubiquiti AirOS supported those frequencies natively. So one wonders if one day even Mikrotik might have those features removed. Speaking of BBHN is there any kind of video showing the more nuts and bolts of it working for those of us who (or want to) understand things a bit deeper? A video that perhaps shows broadband hamnet speed test (FTP transfer to a localhost, etc) traceroutes to show hops when a node disappears or comes online broadband hamnet route command output when a node disappears Steve ---- Quote ----- If you want to get out of the part 15 jungle just use Mikrotik gear... It won't run HSMM mesh but that's not a bad thing if you don't want to pay the performance penalty of a mesh... Bill

Call for : Extended Frequency Support
by Steve L 09 Oct '14

Atheros Chipset Radios are capable of operation between 2312-2732, 4920-6100 MHz. The purpose of this message is to hopefully draw a few talented hams out of the wood work that can make a programming contribution to an the existing Broadband Ham Network firmware project. You can look at how the ham radio frequency allocations overlap the Part 15 bands here: http://www.qsl.net/kb9mwr/projects/wireless/allocations.html The Part 15 overlap where all consumer devices operate is heavily crowded, and thusly the noise floor is high hampering long range links that we as hams would like to establish. There are a couple third party solutions to enable the extended frequency support to be able to shift operations into the ham only portions of the bands. Neither of them presently have native OLSR support in addition to the extended frequency support. It would be highly desirable to see our own ham firmware support the extended frequency support. HSMM-Mesh / Broadband Hamnet Firmware In the Fall of 2008, a group of amateurs from the Texas area announced development of their own custom firmware for the WRT-54G to enable HSMM-Mesh networking. This is the first ham specific firmware build. It is also one of the first firmware builds to support OLSR, an ad-hoc wireless mesh routing daemon. Initially this ham firmware build was limited to the Linksys WRT54 series of wireless routers. In February 2014 the development team announced support for Ubiquiti 2.4 GHz devices. In July 2014 support was extended to Ubiquiti 5 GHz devices. I should clarify that this firmware does not yet support non-part 15 channels, aka, extended channels / custom frequencies. Nor does it yet support half-rate (10 MHz wide), or quarter-rate (5 MHz wide) bandwidth channels to accompany use on ham only spectrum. If you are knowledgeable with the Linux Kernel programming please consider reaching out to the development team. http://www.broadband-hamnet.org/download/firmware/ A discussion on the Broadband Hamnet / HSMM-Mesh ham firmware about using channels outside of the Part 15 space: http://www.broadband-hamnet.org/hsmm-mesh-forums/view-postlist/forum-1113/t… If we can develop the firmware that enables ham channels, Heikki Hannikainen OH7LZB presented at the 2013 DCC a way to authenticate the person who might like to download it is a ham. http://www.youtube.com/watch?v=7anDmQQfyu8 Video presentation from the DCC http://authtest.aprs.fi - authentication demo site https://github.com/hessu/ham-cert-web-demo - Apache configuration and PHP scripts

Greetings; I have created a file at http://n1uro.ampr.org/amprdns.brk This file contains a ton of stray MX and CNAME records. If a coordinator wishes to sort through it and clean up invalid entries, it's there. -- 73 de Brian Rogers - N1URO email: <n1uro(a)n1uro.ampr.org> Web: http://www.n1uro.net/ Ampr1: http://n1uro.ampr.org/ Ampr2: http://nos.n1uro.ampr.org Linux Amateur Radio Services axMail-Fax & URONode AmprNet coordinator for: Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, Pennsylvania, Rhode Island, and Vermont.

Greetings to everybody. Following Shellshock... There is another hole, called tmUnblock.cgi targetted on some Cisco Linksys routers: http://www.scip.ch/en/?vuldb.12362 More info on Internet, for instance: http://security.stackexchange.com/questions/68405/what-is-tmunblock-cgi-and… Even targeted at specific hardware, it is poking everywhere... Short extract from my apache2.log 50.193.84.18 - - [05/Oct/2014:14:03:33 +0200] "GET /tmUnblock.cgi HTTP/1.1" 400 518 "-" "-" Best regards. Tom - sp2lob
