Why is Linux box necessary?
by YT9TP op. Pedja 27 Jul '13

27 Jul '13

Hi, First time posting on this list. I am new to AMPRNet and actually still struggling to make gateway. I realized that I have to download encap file with route definitions and load them into my gateway router so my networks sees all other networks in 44/8. It is suggested that I have to get up Linux box that will do the gateway job. Thing is, I want to use Mikrotik router that I already have in use, and which handles my network. I do not need another box just to play gateway. I do not understand why standard dynamic routing protocol is not used in first place, so we would not have this issue at all as all routers are capable of dynamic routing?!?! I noticed that there is a script made by Marius, YO2LOJ, that reads encap file and then sets Mikrotik up to it. But, to run that script I again need Linux box. I noticed there are other scripts that do the same for other kind of routers. I guess there are number of fellow hams that would like to use already set router and not additional Linux box. Why then such scripts are not run at portal.ampr.org so we can, besides encap file, download prepared files for popular routers, so we do not need to make conversions for ourselves? If such download is provided, I would be able make Mikrotik itself to download file and run it to set routes. I would not need additional Linux box to do that. That would make whole process simpler, easier to implement and even cheaper (in manner not just money, but efforts, physical space, maintenance...) and that could motivate more people to get involved. If resources on portal.ampr.org are limited, mirror copies of those files could be easily established to prevent problems. YT9TP Pedja

A Juniper O-series might work ;) I think the 2811s from cisco are cheap enough now (under 400 on ebay). The issue with cisco is you need some one to get the code for you now that they've locked down the CCO site. I'd love to use ALU gear, but it's just to expensive on the used market. But this is all just discussion on how we wan to do it at this point. We'll need some detailed proposals and come to a conciseness on it. -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net

Newbie issue

Marc, LX1DUC, Per Brian in a Jan 22 note: 44.0.0.1 responds to pings received from the Internet. It does not respond to pings coming into it over an encap connection to it, for some reason that I've not been able to figure out. I believe it to be a difficulty in getting it to recognize decapped pings. If you are receiving the rip44 announcements, you have properly configured your tunnel to receive IP-in-IP encapsulation from 44.0.0.1. Feel free to use: http://44.60.44.10/tools or http://kb3vwg-010.ampr.org/tools I see your encap as: 44.161.202.0 via 46.29.183.253 dev tunl0 onlink window 840 44.161.203.0 via 46.29.183.253 dev tunl0 onlink window 840 44.161.229.0 via 46.29.183.253 dev tunl0 onlink window 840 Also, I am unable to ping 44.161.229.126. What script/configuration did you use to enable your tunnel; did you specify a local or remote IP (un-needed)? Feel free to look at my script at http://44.60.44.13/startampr 73, Lynwood KB3VWG

Services That Can Run on 1K2/9K6 RF
by n2nov＠n2nov.ampr.org 26 Jul '13

26 Jul '13

I have been following the conversation on what can we use the modern version of the 44net for other than a futile attempt to compete with cable modems, 4G/LTE or fiber-optic links. The purpose of the 44net/JNOS project that we are putting together for NYC-ARECS is for providing email/telnet services for a served client in case their connection goes down or does not exist in an ad-hoc location. I am wondering if we can expand on the usual email and telnet sessions at 1k2 or even 9k6 to include things like routing our own VoIP/Echolink-type connections? The Echolink manual states that it needs 24K+ data speeds to connect to it's servers and maintain a voice connection. I know that there are other codecs that can work at lower speeds as well as ongoing work with FreeDV operating in 1.5 Khz on 20 meters! Ideas anyone?

This is one of the reasons I got out of radio for a number of years, as it was not new or challenging due to these guys. I want to sit down an study if I don't understand it, not gripe about it (and my angina) on FM. We really have two discussions here. One is global BGP peering and a 44-net back bone, the other is the end user connecting over tunnels or dedicated links to the backbone. The backbone should be based on standard routing protocols and be vendor agnostic (ie ALU/CSCO/JNPR), as I could see having a router and peering link donated, but if we need to rack a linux box, we'll have an issue. The individual backbone POP's can interconnect with the end users over any method they want. (I'd say we need to support IPIP or GRE tunnels as standard at any POP) For an end user wanting a /29 or /31 they would pick a "local" AMPR POP, and link in with them. Thoughts? -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net

I've been running Cisco 1811's and 2800's in my local lan at home connecting me to my datacenter in tampa. (don't tell my day job, lol). I am running the MSS adjust and have no issues with it. Even without it, all major sites on the internet work, only smaller sites have an issue. We should not be limiting ourselves due to other peoples broken network designs. On the internet between peering points, where clue is found, I've never had an issue with icmp blocked. Now on the GRX, yes.... -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net

I'm about as far from San Diego as you can get and still be in the US :) I'm in St Petersburg, FL. Not many local hams here who want to mess with this stuff, I have a few who I know from work and we're playing with some re-purposed Alvarion radios. -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net

I guess it will kind of boil down to applications. And a way to advertise them to everyone else who has access to the network. Here are some random ideas Make a mirror of mods.dk or something like it, are their any unlimited mod sites? As far as I know you can only lookup one per day. How about a part-number datasheet lookup service? Or periodical lookup. Or hosting services for ham software development projects. For a good place to start how about someone setup a listserver on the amprnet, perhaps "ampr-services"? It would probably be a good idea if there was a way for the HSMM nodes to have a way to tunnel to other remote nodes. Maybe touch base with the firmware developers?
