Test New Tool - APRS Code Recovery
by lleachii＠aol.com 24 Jun '15

24 Jun '15

All, I've added a new tool that I'd like you to test. This web application should provide the registration code required by APRS software suites. In order to use it, you must browse to: http://kb3vwg-010.ampr.org/tools/aprscode or http://44.60.44.10/tools/aprscode If you're on AMPRNet, you should be able to enter the callsign and look up the registration code. If you access it from outside of AMPRNet, you will be prompted for an access code (1234). Please let me know how it works 73, KB3VWG

New services idea.

First, Lynwood thanks for sharing PHP code snippet. Does anyone know much about google maps? More than 15 years ago a younger local ham friend of mine wrote some web based interactive tools for wireless link planning. Maybe you have run into them: http://n9zia.ampr.org/ This isn't presently on 44-net. I have just been using the ampr dns to give it a hostname that has been pointing to my home cable modem for a long time now. They run horribly slow (same computer for 15 years and slow upload speed) I'd love to see these tools freshened up a bit to use PHP, and possibly integrate google maps. Neither the original author, Joe N9ZIA or myself really have a lot of experience with either. But we are both surprised someone hasn't already done this. Just throwing the idea out there for anyone who would like a project, the code is open under GPL. The tools help promote modern RF network planning. After a rewrite perhaps they could be hosted on a 44 IP, and put a paypal please donate nag screen if you come in from a commercial IP. The paypal proceeds can go to helping ARDC with Brian's ok.

AMPR Gateway down?
by lx1duc＠laru.lu 28 May '14

Good afternoon/morning, I'm unable traceroute from the internet to 44.161.200.11, the trace stops at ebu3b-6509-nodem-core-interconnect-vl910-bcast-255-131.ucsd.edu (132.239.255.131). Is anybody experiencing similar issues? 73 de Marc, LX1DUC

Gateways to where?
by kb9mwr＠gmail.com 28 May '14

I have been reading this common thread on the.broadband hamnet forums. "Are there any lists with available tunnel connections?" On the portal, unless noted in the notes area, the only way to really tell is from looking up the geographic area for the listed subnet. This is probably something we should re-think. You shouldn't have to do all that leg work to see what areas have tunnels available. If we can make that easier to determine, I'd like to think more people will find what we are doing here on 44net more useful to them. Back to painful data loss recovery..

Strange route entry: 44.140.0.0/16
by Marius Petrescu 23 May '14

23 May '14

Just peeked in th RIP broadcasts today: 44.140.0.0/16 via 44.140.0.1 This entry is invalid, since the gateway is in its own subnet and no other entry for 44.140.0.1 exists. Please correct the entry. Marius, YO2LOJ

This really needs to be in the wiki, or else no one can find it. It can be dangerous for total newbs to read this, because it suggests the process is fraught with danger, which of course it's not. We all agree that it's actually completely trivial to put up an AP and connect to it from miles away. rmonline is also a good tool to quickly check links for LOS. There is also some Android app as well. http://www.ve2dbe.com/rmonline.html I don't do link calcs any more - there's just no need to. A pair of Nanobridges will work real well over a huge distance provided there is line-of-sight. Really, this stuff is point-and-shoot trivial now. A really important consideration with an 802.11 ham network, is keeping the snake-oil protocols separate from the ones that actually work! Viz, don't run mesh on an AirMax channel. AirMax can push a huge amount of data, even on a busy channel. Advice I'd give to a group of total newbies who want to build a network, is ignore all the tech talk and go buy a 2.4GHz AirMax sector access point, install on a nice high line-of-sight location, and just play with connecting to it from all around the place. There's nothing complicated about it at all. The tricky stuff does come later, but you'll get to that once you see the network up and alive, and your enthusiasm starts to take off. Newbs giving up early because it looks too hard is an avoidable tragedy. Steve ZL1BHD

Oh but that is because pe1chl.ampr.org allows only traffic from net-44. It is a NET system and I don't want to open it to the abusers and portscanners. Try sys2.pe1chl.ampr.org or www.pe1chl.ampr.org. Those are Linux systems and you can ping them both from net-44 and from the entire internet. > > In fact a ping to any ampr.org does go to amprgw (169.228.66.251) as shown > by traces, and that happens using any system being or not a linux. > > Question is how to resolve this, and reason of seeking help/advice from > amprnet experts to guide toward finding a solution. > > Best 73, > lu7abf, Pedro Converso What I deduced from your trace was that incoming the packets were encapped as IP-in-IP but outgoing they were not. But maybe it is a characteristic of the way you traced, sometimes those extra encapsulations are not shown in a trace. I think the best solution today is to handle the net-44 routing in Linux and then when you want to run jnos put that behind an extra address that you route locally. Rob

802.11 link planning
by Michael E Fox - N6MEF 21 May '14

All, I know some on this list have already rolled out substantial 802.11 outdoor networks. For those who are getting started, this preso might be helpful. I put it together to help new folks in our area understand how all the numbers and terminology fits together. http://www.scc-ares-races.org/mesh/preso/Basic_WiFi_Net_Planning_v140516.pdf At some point, I may follow up with a white paper on how to calculate various items of interest, such as: -- what speed can I expect from a given link? -- what is the minimum antenna gain I need for a given link? -- etc. Michael, N6MEF
