The "ipip" protocol is protocol 94, the one that was registered mistakenly at a time when protocol 4, which does exactly the same, already existed. Now the protocol 4 is used, which is in /etc/protocols under its name "ip". So use -p ip or just -p 4. Rob

Cisco/juniper configs?

by Bryan Fields

Greetings, I've been doing some work to get the IPIP tunnel information into a router on a daily basis, has anyone else automated this? I was wondering how the reachability of this from the global routing table of the public internet works, if at all. Everything I've been reading says this is all separate, but we do interconnect at a couple locations. I must admit I'm new to this, but is 44/8 intended to be totally separate a la the GRX network? Granted my use of this space is for high speed wireless networks on the ham bands, I have little interest in the 9.6 kilobaud TCP/IP packet radio. I've got some of the 900MHz FHSS gear hacked to run in a narrower channel, and I've been experimenting with running some of the 5ghz units in the ham band at 5cm (5mhz channel is able to do about 10mbit/s). My intention is to have it all work across hardware routers, ie cisco/ALU/juniper rather than maintain a bunch of linux boxes. Thoughts? -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net

When adding the route statement to the initialization sequence, make sure the wlan0 interface exists; don't put it too early in the sequence.

SIP Service on AMPRnet

by Marc, LX1DUC

Dear YLs and OMs, I have installed a SIP service on sipwise.ampr.org. It allows SIP users to do voice & video calls, instant messaging (via SIP), screen sharing, etc. There is also support for voicemail, call forwarding and call forking (upto 5 user-agents (devices, softphones, etc) per account). The system accepts calls from outside, try sip:lx1duc@sipwise.ampr.org or sip:+883510001204400@sipwise.ampr.org. (I'm using iNUM numbers to provide a globally unique numeric identifier so that hardware phones can make calls to other stations as well, while it's possible to dial "lx1duc" from a numeric keypad, it's more convenient for the user to actually dial a number H-I-H-I.) I'm using it on my mobile via a softphone right now (I didn't have time to configure my hardware phone), but the plan is to use it on hardware phones in our club shacks in LX. You're welcome to test it and if you want/need your own account please contact me off-list. I'm also interested in peering with other SIP services as well, so if you're running one and you're interested in peering, please contact me off-list. 73 de Marc, LX1DUC

Why rip44d?

by Michael E. Fox - N6MEF

This is a serious question: Why is everyone so enamored with and focused on using rip44d? Rip44d disadvantages: 1) Rip44d depends on getting the routes from a single source - amprgw, i.e. a single point of failure. 2) If that single source fails (as it did recently, for more than 12 hours), then the routes are gone, even though all of the other gateways may be completely reachable. 3) If you try to avoid that problem by timing out the routes slowly, then you might as well have a static list. It seems to me that periodic downloading of the encaps file, followed by the ip.munge scripts is a far better approach. Advantages: 1) You can define how often you want to download the file, based on how quickly you want to discover new gateways. For me, once nightly is fine. But it could be more often. 2) If the download of encaps fails, I continue using the same routes I had before until the next download attempt. This happens every once in a while - maybe once a month, for whatever reason. But no connectivity is lost. 3) If amprgw fails, the direct tunnels to all other gateways are unaffected. i.e. Single point of failure eliminated. Disadvantages: None that I can see. So I fail to see why everyone is so enamored with rip44d. Please explain. Thanks much, Michael N6MEF

Re: [44net] Why rip44d?

by Brian Kantor

Seems to me that encap routes learned by rip44 should be fairly persistant - I'd say they shouldn't expire for a day or three or more. Perhaps a week? Unless replaced by a newer route for the same subnet, of course. That way if the rip sender (amprgw) should happen to go away for a while, things will still function. And you'd have time to switch over to using the encap file if the outage were to be prolonged. There's no harm in having a dormant route in your table for a while when a gateway permanently goes away. What's the maximum rip44 route expiration time setting? You could, of course, decide to NEVER expire them. With daemon modification, they could be persistent across reboots and only purged when manually selected. - Brian

rip44d / kernel multicast support

by Heikki Hannikainen

I think the lack of multicast support in some Linux kernel builds makes the Perl rip44d fail for some users. Linux 2.6 certainly supports multicast, it's been in the kernel for a long while (at least in kernel 1.2 it was there, and probably before that). Some distributions apparently haven't compiled in the multicast code. If you're having problems with rip44d not receiving RIP packets, and you're not one of those having a NAT/DMZ router of some sort in front of the gateway, please check if your kernel has multicast enabled: http://unix.stackexchange.com/questions/25872/how-can-i-know-if-ip-multicas… I can probably add raw socket support to rip44d, mimicking what Marius did in his C version, to work around it, if this is indeed a problem. One alternative is to run the C daemon on those systems, of course! - Hessu, OH7LZB On Tue, Aug 6, 2013 at 2:08 AM, Brian Rogers <n1uro(a)n1uro.ampr.org> wrote: > On Sat, 2013-08-03 at 11:46 +0300, Marius Petrescu spake: >> I added an option to use raw sockets instead of multicast to the daemon. >> This is needed on systems that do not support multicast properly. >> On system where it works, there is no need to upgrade. > > Thank you Marius - it's definately now doing what it needs to do!

Running on RPi. Still got issues

by Mark Phillips

Hi folks, So I was able to compile Maiko's latest JNOS code for my RPi and it appears to function correctly. I have one of John Hansen's TNC-Pi's which also seems to work using the I2CKISS stuff. I have the AGW remote modem stuff working. I was even able to get the encap stuff working via my pFsense FW with the aid of this rather useful posting http://forum.pfsense.org/index.php?topic=64060.0 and the encap.txt file. However, whilst I'm receiving UCSD's RIP broadcasts at my FW they are not making it through to JNOS. I've tried forwarding UDP port 520 however that does not seem to work as pFsense traps the RIP session as an IPIP session. This further confuses me as IPIP sessions are correctly sent to JNOS per the above. I have also tried activating the RIP daemon in pFsense and then getting JNOS to ask for a RIP update but that doesn't seem to work either. Ideas? Thanks Mark, G7LTT/NI2O Randolph, NJ

It also needs to be discussed what functionality is required here for both the users and the coordinator. Sometimes I get requests for approval, and I just looked in the portal.ampr.org again, but it does not really cover the requirements. What we need is a request from a user to get one or more addresses allocated, accompanied by information like region where they live. The coordinator then must be able to look into the already assigned list of addresses and find an available address in the correct region (subnet), assign it, and return the address to the requester. As it is now, I get requests for 44.137.0.0/16 which makes little sense. Until now I have a hosts file and I make the assignment by browsing through it in the editor, and copy/pasting a line. Then I send the corresponding update to the ampraddr robot. How can we do this in the portal when we abandon the hosts files? Rob

Neil, Can you share these scripts or the links to what you used as a base. I can see myself doing this once the DNS part of the portal is functional. Steve, KB9MWR WI/Upper MI Coordinator ---- Quote ---- Having just volunteered as a coordinator for the state of Iowa (44.50.0.0/16). I went through the amprhost file and: - Pulled out all the IP address entries for the state. - Manually pulled out the call signs from the host names. - Modified a python script I found on github ( called qrz.py) to get as many email addresses as I could from qrz.com, - Used another python script to send a nicely formatted e-mail to each user asking them to register their IP on the portal or tell me if they no longer needed it. Stated in the e-mail that if I didn't hear from them in 90 days. I would reclaim their allocation. - The plan is to send a reminder email at 60, 30, and 7 days. I'm not sure what I will do with those call signs that don't have e-mails associated with them (56 out of 175). Possibly send a post card ? Of the 119 e-mails I sent, I've received 27 responses so far. 20 saying I can reclaim their allocation, and 7 requests through the portal. The previous volunteer did a wonderful job of dividing up the state into regions, sub-regions, and cities, but assumed there would be only one gateway per city. I'll have to understand the existing network topology and see if I can fit them into new subnet boundaries. -Neil

gateways sunset

by Brian Kantor

As many of you know, when we set up the portal and moved the gateways maintenance to it, we imported the legacy gateways file which included a significant number of dormant or abandoned gateway entries. Since then we've requested that people operating gateways "take possession" of them by registering their active gateways. I believe the time has come to flush all the gateway entries which have not been registered -- clearly by now if they're not registered they must be abandoned. So I propose that we use the month of August to get the last of the active gateways registered with the portal, and after the last day of the month we remove all unregistered gateways from the gateways files. What will remain are the gateways that are still active and being operated by somebody. This should make the tunnels routing table a bit smaller. Comments? - Brian

question regarding amprgw.sysnet.ucsd.edu

by Blaine Forbort

Hi all, I've just set up my net44 gateway using a Debian machine running in the cloud with a static IP. My plan is to use this machine as an IPIP-to-OpenVPN adapter so that I can run my subnet from home via my LTE connection, with will not support IPIP. I set up the machine with Debian linux and rip44d. I'm currently receiving the routing table from 44.0.0.1, and I'm able to ping several net44 machines in my area (44.4.2.153 and 44.4.50.1 for example), however, my linux machine is not able to ping 44.0.0.1. At first I assumed that this was a security policy, however, I'm also not able to access the ampr.org website from that machine now. in addition, I'm unable to ping my machine's net44 address from the internet. Is this a result of gw.ampr.org not updating it's gateway list, and thus not knowing how to route to me, or have I missed something obvious? Also, if anyone with a properly maintained gateway list could ping me at 44.4.36.1 and let me know the result, I'd appreciate it. Thank you, Blaine -- Blaine Forbort, K1QV Vallejo California

I am okay with that. When or is someone working on cleaning the DNS up next? Someone mentioned the idea of sorting hosts that are theoretically reachable via a tunnel. Then possibly purging ones that are not, or at least further review of these. I gave it a quick try before, as it seemed simple enough. Look at the encap.txt file, look for hosts in each CIDR... (checking this file: ftp://hamradio.ucsd.edu/pub/amprhosts.) A quick google search yielded this nifty function that is the magic to the whole thing http://stackoverflow.com/questions/594112/matching-an-ip-to-a-cidr-mask-in-… http://pastebin.com/rbFuTeVi It's not quite working, maybe someone who knows more can fix it?

In my version, the MSS was automatically calculated from the MTU of the incoming and outgoing interface in the IP routing code. It worked very well. (MTU discovery did not exist back then) In 2001, Cisco introduced it in IOS and I realized I should have patented it :-) From changelog: PE1CHL.950819: TCP SYN packets are examined when routed, and the MSS option will be adjusted down to the maximum MSS possible on the incoming and outgoing interfaces. Thus, a more optimal end-to-end MSS is chosen, and fragmentation is avoided (e.g. when running IP over NET/ROM somewhere inbetween the endpoints) Rob

Tunnel issues with rip44d

Why is Linux box necessary?

by YT9TP op. Pedja

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).

Newbie issue

by lleachii＠aol.com

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.

Services That Can Run on 1K2/9K6 RF

by n2nov＠n2nov.ampr.org

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.

Re: [44net] On The Air

by kb9mwr＠gmail.com

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?

BGP / Tunnels / JNOS

by K7VE - John

My thoughts. The IPIP / JNOS network is an anachronism that is quant but doesn't take advantage of how technology has evolved. I'm a pretty skilled network guy but the current IPIP tunnel system has eluded me. I have gotten close, but finally thrown my hands up each time. (I never get the rip44d to run and find the proper password.) However, I can get a VPN tunnel running in short order which can bring an address range to whatever location is on the full Internet. I have a personal class-C at home that has functioned over a VPN for over a year and I have VPN'ed to another Net-44 gateway with success. (In both cases on inexpensive MikroTik routers.) I think we need to work on connectivity of the gateways to unify Net-44 and treat the "on air" connectivity as a separate task. Whether the on air connectivity is for IP over AX.25 at 1200 bps, WiFi/HSMM, D-STAR Digital Data, or some new transport over RF. It doesn't do a lot of good to have islands of on air activity without interconnectivity of Net-44. Otherwise just use RFC 1918 address space and NAT it to the Internet. My vision is that we have multiple BGP gateways on the Internet. Some may advertise the whole of 44/8 and others may have smaller networks, clear down to 44.x.x.x/24 Some will be multi-homed, some will not, but all would be advertised to the Internet for routing. Any router advertising all of 44/8 would need to know about all routes for anything with a CIDR of less than /8. I don't think we really want all traffic to go to 1 or 2 routers advertising 44/8 or we're back to the everything must go through UCSD scenario of the last couple of decades. My recommendation is to find ISPs who are willing to 'donate' bandwidth and routing for some number of BGP'ed networks, then place routers at those ISPs which will support authenticated VPN service to local networks. Say we had an ISP (or University, etc.) that would donate bandwidth for 44.24.0.0/16 and 44.12.0.0/16,44.26.0.0/16, and 44.40.0.0/16 and BGP advertise those ranges. Let's another data center wanted to BGP 44.24.100.0/24. Traffic would flow to the best gateway for each. If 44.24.10.0/24 didn't have the ability to BGP its own address space, it could VPN to the router at the major gateway (ISP) and that router would tunnel traffic for that network to the gateway for 44.24.10.0/24. Then there might be a small on the air network at 44.24.128.0/28 and its gateway would VPN to the 44.24.10.0/24 router who would route traffic for the small network. This would mean that no special tables need to be passed around. Each router would know the addresses it was responsible for and would route all other 44 traffic to its "upstream" and non-44 network traffic to the Internet through their service provider. This means the "heavy lifting" of BGP and network routing would be handled by those ISPs where the expertise exists and a new member of Net-44 could simply setup a simple router that VPN'ed to an upstream router to get its traffic and to send Net-44 traffic, all other traffic would simply pass over local service provider's network. This is all readily available, off the shelf, technology. For the end user it is very inexpensive to setup a router with VPN. Then the local distribution over RF can happen over whatever technology is available, whether a TNC and FM radio, WiFi dongle, UDR56k-4, Bullet, etc. ________________________________ John D.

We have really two networks here. The internal 44-net and the external internet facing net. I'd propose to have a few points around the globe where we can peer the whole 44 internet facing net. Each of these locations would announce 44/8 and more specific routes for what's close to them. Behind this in the 44-net internal the gateway routers would be meshed over GRE tunnels running an IGP (IS-IS). There of course would need to be IBGP sessions between all the BGP speakers, but this would allow end user networks to tunnel to a given 44/net router, and not need to keep a full route table of the 44-net internal space. (I hate end stations needing to do routing, that's why we have routers!) This would provide full access to the 44/net from outside, easy access from the AMPR users, and full visibility between directly routed netblocks and the rest of 44-net with out having to maintain a full mesh. I'd imagine the more specific announcements from the peering points would be statically configured, but there is a way to do a limited redistribution from the IGP into the BGP. I think it would be easier to do it manually (and more stable), but given some time in the lab at work I could get this going.

Say we had an ISP (or University, etc.) that would donate bandwidth for 44.24.0.0/16 and 44.12.0.0/16, 44.26.0.0/16, and 44.40.0.0/16 and BGP advertise those ranges. Let's another data center wanted to BGP 44.24.100.0/24. Traffic would flow to the best gateway for each. If 44.24.10.0/24 didn't have the ability to BGP its own address space, it could VPN to the router at the major gateway (ISP) and that router would tunnel traffic for that network to the gateway for 44.24.10.0/24. Then there might be a small on the air network at 44.24.128.0/28 and its gateway would VPN to the 44.24.10.0/24 router who would route traffic for the small network. This would mean that no special tables need to be passed around. Each router would know the addresses it was responsible for and would route all other 44 traffic to its "upstream" and non-44 network traffic to the Internet through their service provider. This means the "heavy lifting" of BGP and network routing would be handled by those ISPs where the expertise exists and a new member of Net-44 could simply setup a simple router that VPN'ed to an upstream router to get its traffic and to send Net-44 traffic, all other traffic would simply pass over local service provider's network. This is all readily available, off the shelf, technology. For the end user it is very inexpensive to setup a router with VPN. Then the local distribution over RF can happen over whatever technology is available, whether a TNC and FM radio, WiFi dongle, UDR56k-4, Bullet, etc. ------------------------------ John D.

Distributed BGP Announce

by Marc, LX1DUC

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear YLs and OMs, I would like to restart the discussion about a decentralized BGP setup for the 44net. I have thought about some kind of trial to test several aspects of a non-central gateway approach. So far I have come up with a few "challenges" for the trial. - - AS Number (I can provide one for the trial, we may decide later on what to do if and when this project goes to production) - - IP Network (for the trial the test range 44.128.0.0/16 might be a suitable candidate) - - BGP Peers providing BGP session, bandwidth and a static IP address for the trial (I can provide one peer in LX) - - Inter-Gateway Tunnel setup (which protocol should we use? How do we cope with lowered MTU and filtered ICMP Packet-to-big messages?) - - Downstream tunnels (What kind of tunnel technology/protocols are we offering? Can a subnet have upstream tunnels to several gateways?) - - iBGP setup (How do we handle gateways with different available upstream bandwidth? How do we redistribute routes for connected subnets?) - - Packet filtering (Will we be using the current model of RDNS activates access to/from the Internet? RDNS could be useful even for hosts that shouldn't have access to/from the Internet, eventually access to/from the Internet should be decoupled from RDNS.) - - Test scenarios, how are we going to test different situations? - - probably much more issues to handle (I haven't thought about the details as long as the basics haven't been discussed) What are your thoughts and who is willing (and able) to help with the trial (as a gateway and/or a subnet tunnel server)? 73 de Marc, LX1DUC - -- http://lx1duc.mcs.tel -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.19 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJR7v2YAAoJEHFIN1T8ZA8vJSQQAIFoXAKTS7IKJ6SxRavGb0oa ySXvtPQg1TjhU5bGkN46efSQkAhsY7BcOg+3JwNTVEpTW5ZLO3ieN1kRKcgD/uVh fI4z70HeFvQJeE6l2TeZxYkKU45fNEBKNQHqRRn2QU7wOHqvhOtr+jjR4UswbWIG PyFoUEF/T7wd2jpZ6O0hA4buOy+DnMpBUeUQCQIeu7xs5+YpFGc1D21Fbo5b24FG GLTUl4b+ssYdLf+CiFy1TlOu1wLOZorZ3DrYjexxGvpUzEUHjrazNr/pUKIc1WMq zs3cQFTKNyjWf984Ty8WeuKrP/oy5gNFIbTmxlzm4JNYqDjPpQXZ/3Cduu/ij8Yl n1qDAwe+PDFHh1DUVTdgiy+3JSsUy7q2GwItiJG5pOtFasLeoWeLs9iXR5dNBqtD E8O9R7WRL989igv2XXVitwpDaiiDIpZG47kkktljFfhSiY6RtiozQRuuncQzm6bQ 0Ixl0u1Ne0B8aeQqfzUDfs6UqtoRPPoqJbRFimD22tAZg9dn50z180jU3b5oc/xX tD06xi2CwscFLPlRknxxj/TFDfySjOHOJCmGPHUR/uBIs7ABqciY5NVkNpmPklUa A3AW4J0uwVTB3iUpuZXktny/epj6ULg3R/FMU5Ym8Y9XFgp52km+vCvsbg9bPhtv DQ22F6oMccLigj/6h0I+ =8ova -----END PGP SIGNATURE-----

If they wanted to have redundancy into the AMPR net they could do IS-IS L1 to the two gateways over these tunnels. The backbone routers would all be L2 routers.

Re: [44net] (no subject)

by kb9mwr＠gmail.com

Bill, I am not yet. Still using hard routes over the air. When/if the over-the-air network grows in users and capable speed, that would make perfect sense to implement. As for ampr.org email, does anyone care to document setting up a sendmail server for their gateway? Spam control is always a big headache. I have been using a 3rd party mail exchanger, as that seems easier. And since my gateways are somewhat experimental here, I am not subscribed using kb9mwr(a)kb9mwr.ampr.org to this list, as I don't like worrying about bounced mail. But my ampr address does work, and go over RF using pop3 pooling. Steve ------Quote----- So how are folks actually making use of all this nifty routing technology on the air with Amateur Radio these days?

We still > need the tunnels for that. Admittedly, I've been a bit tardy in getting my BGP session up with my provider (summer is always busy for me), but perhaps there is a better way to do this. What I envision would be to have a few regional AMPR BGP routers/peering points. AMPR would need and ASN of course (I'd be willing to put up the money for this from ARIN), some hardware and a few friendly providers across the globe. I have one friendly provider, and I'm sure we could find a few more. Hardware is up to us, I'd prefer an actual router (ALU/Cisco/JNPR), but there is no reason openbgpd on a *nix box wouldn't work. So you would have each peering point announcing 44/8 but behind the peering routers would be a set of (GRE) tunnels between all the routers. The 44net BGP routers would run I-BGP across these tunnels (or ISIS/OSPF, but I feel IBGP would make more sense to manage redistribution of routes as it's got more "policy knobs" than OSPF and to a lessor extent ISIS.) The 44net non bgp users would then have IP-IP tunnels to their closest 44net peering router. For optimized routing (as it makes no sense to me for .AU users to tunnel through UCSD) we could have routing between the 44net routers announce more specific routes for directly connected subnets. We'd have to manage this, as I'm sure we don't want to add another 1000 routes to the global table (and then have filtering), but I don't see it being that many routes when a /16 is for a whole continent, which has 1 or 2 peering routers in this design. This also avoids black holes caused by 44net directly connected peers being filtered by sites that filter at less than a /24 block (don't laugh, I've seen large companies filter at a /19) Admittedly this is a very "back of a napkin" design, but it's a start.

Along those lines, Remi, F4ECW had an interesting idea to make PHP interface for remote fldigi. I took some his radio control code and put my receiver online. http://kb9mwr.no-ip.org/control/ Another logical use of the 44 netspace would be for a VOIP ham thing like IRLP. This would eliminate the need for port forwarding ---- Quote ---- Interoperability with the Internet, thanks to the BGP announcements and not using 10/8, *and* at the same time, access to the same services from ham radio networks which are not allowed to access the Internet over ham radio due to local regulations. That'd be cool. Run a nice web service having a net-44 address, but when the visitor comes from within the amprnet with a net-44 address, allow extra features like being able to key a transmitter. - Hessu

Connectivity to AMPRnet and video

by Jesse Hindmarsh

In one of my last posts, I mentioned about connecting to the AMPRnet via DMVPN or PPTP which seemed to tangent into a hardware/software discussion. I sat quietly and enjoyed the many perspectives that many had to share. I have been connecting via a combination of Linux and DMVPN for the last two weeks and it has worked as expected. A few even used the PPTP service I have setup and had good results. I want to get some services deployed to see how flexible this setup is and if there are any issues before I attempt to extend my network using 2 ghz and 5 ghz links across the valley. Right now I have a videoconference station setup on 44.64.192.2 which anyone is welcome to connect to. Thanks Jesse - WC3XS Sent from my iPhone

Re: [44net] hardware vs. software

by lleachii＠aol.com

Regarding a few things mentioned setup/encryption - 802.11 encryption would not be necessary if you use a band not shared with Part 15 Users - 802.11 encryption technically does not obscure the fact that you are transmitting standard 802.11 Wireless Ethernet traffic - also, this debate can extend into HTTPS traffic over Amateur RF, except in an Emergency (transferring Health information for a hospital, for example, REQUIRES encryption in the US [HIPPA]) - even if HTTPS traffic is sent, packet inspection of the frames would reveal it is a HTTPS packet, its source and its destination - making the callsign the SSID is not the only method of complying with station identification rules; but it is the easiest - There are other methods of encrypting a WiFi signal other than a pre-shared key (many stations commented that they key must be posted or announced), user account authentication is another method regulation - regarding sending a music/video file or stream via 802.11 - the communication would be data, in the analog world, I would assume this would be similar to sending the sheet music via snail mail - regarding N6MEF's concern regarding 3rd party email communications, email is not an "automatically forwarded" technology; an amateur does not automatically receive that message through any technology governed by Part 97 (there are two exceptions I can imagine - if the amateur maintains his own email server at the receiving [client] end of the radio link or provides email as a service to non-amateurs) - I'm somewhat lost as to the concerns regarding inbound traffic, the problem only arises if the intent is to run infrastructure (i.e. services) over RF for non-amateur use, otherwise, the requests would initiate from an amateur station and would not be 3rd party - servers and devices on AMPR can be firewalled to only accept traffic from 44.0.0.0/8, in fact my DNS server (44.60.44.3) is configured to only resolve non AMPR IPs and domains for 44/8 traffic - if a non-amateur is reaching a 44/8, they MUST be using commodity Internet, if the services are on the gateway or on a device connected by wire or Part 15 device, that is not governed by Part 97 (Part 97 only governs Amateur RF) - I cannot find 97.109(e) - I'm not certain how 97.115 relates, except for 97.115(c) "(c) No station may transmit third party communications while being automatically controlled except a station transmitting a RTTY or data emission." Since it is a data emission, 3rd party communications can be transmitted - I'm not certain how 97.219 applies, given that email is not a message forwarding system for the 3rd party (email receipt must be initiated by the amateur, that communication is between the Amateur and their email server, not between the Amateur and the 3rd party) This is a good thread, and I'm still reading through, I hope I have not missed anything thus far. 73, Lynwood KB3VWG

Re: [44net] Use of higher bands

by Michael E. Fox - N6MEF

Eric, I applaud your intent. But, as far as I can tell, there are several major issues with what you're saying: 1) The FCC rules push me to NOT use amateur bands for data. Any application that is actually useful is going to be something that communicate with non-hams, too. Look at the popularity of WL2K. But Part 97 prohibits traffic from being automatically forwarded if it was originated by a 3rd party. So I can send an email to my grandmother. But she can't send me a message if delivering it would require automatic forwarding (such as between JNOS BBSs) over an amateur frequency to reach me. So that means I need a non-amateur network path to every machine. So we're working on that, including using 5.8G consumer stuff. But, gee whiz, once that's done, and I've got a few Mbps between each system, (and it's encrypted to boot!) why use the amateur frequencies at all? In my mind, studying for and getting an amateur radio license should give you MORE privileges. And sure, we get access to more frequencies, but we're highly restricted on what we can do with them. It's like giving a kid a new bike and then telling him he can only use it in the driveway. What's the point? 2) Can't get there from here. Here in silicon valley, 900 is pretty worthless - much too noisy. 2.4 is very crowded. It's hard to get enough S/N to rise above the noise floor. We shoot point-to-point 5.8G links using 5 degree dishes to give us enough S/N. Sector antennas just didn't work. But we can't use 5.8G at 2 of our locations because trees obstruct the path. Anything higher in frequency would be even worse. 3) COTS is available? I don't think so. Not really in any useful, accessible way. We use the Ubiquity stuff on 5.8G. I don't want to make any modifications that will void a warranty. (Actually, I don't want to dink around with hardware modifications anyway.) But even if that is possible, see problem #1. What would be the point unless it's just to talk to the other hams that have done the same thing? In all of silicon valley -- a few million people -- I can probably count the number of hams with the time and desire to do that on one hand. Now, lest you think I'm just a nay-sayer - you can see what we do here: http://www.scc-ares-races.org/packet.html I'm the sysop for 6 JNOS BBSs, including the gateways and other network stuff. I authored most of the content on the above web page and the pages it links to. (That page doesn't mention the email gateway services we're about to roll out). I think focusing on the technology is the wrong thing to do. Figure out what application you want to enable and then solve that problem. For our county, our application was mostly emcomm and the ability to locate anywhere in the county (literally anywhere, with or without power, with or without Internet) and be able to send/receive text and forms data. The county uses several ICS-type forms. City CERT orgs send damage report summary forms. The hospitals have several forms they use. It's a really big deal for them. That's all made possible by custom software written by several folks here. So, what is the application that will drive more AMPRnet use? Honestly, because of #1 above, I don't think there is one! ;-( But hey, if anyone has ideas, I'm always looking for the next thing.

Re: [44net] hardware vs. software

by Michael E. Fox - N6MEF

Actually, Linux on x86 hardware is just as much of a "hardware-based" solution as any proprietary OS on proprietary hardware is. In fact, Linux on x86 easily outperforms most proprietary hardware solutions up to and beyond the Cisco 7x00 range, especially with the current Intel architecture systems. Vyatta (now part of Brocade) and others have proven that over and over for the last several years. I hope we can establish something that's vendor neutral, rather than any type of single vendor lock-in. Michael N6MEF ---- In the performance class we are operating in, "hardware based" is not really required. A suitable box (processor and ethernet interfaces) and software (e.g. Linux plus some usermode tools) can do the same thing.

We have constructive discussion with the license authority, but in the end we are not the ones that decide. VHF/UHF band popularity has gone down anyway, because of license class changes. Until a decade ago, there was a separate "no code" license class that only allowed operation on VHF/UHF, and a "novice" class that allowed a couple of sub-bands and lower power. Then the code requirement was dropped for everyone, so now "no code" licensees (like me) can operate on all HF bands. "novice" class were given access to most of the HF bands as well. The result was that many active amateurs who always wanted to be on HF but were restrained by the code or exam level requirements now went there, and most DX activity the VHF/UHF bands vanished. There now are only repeaters (mostly silent) and a couple of local channels with very little activity. Tuning over the 2M band you may hear 2 or 3 QSOs. This weekend there was a contest but I only heard a German and a UK station, while a decade ago the SSB segment would be filled with activity. As it is now, there are not enough active hams here to setup and sustain something as involved as a data network. We had one in the past, but interest dropped with the availability of internet for everyone. Sure one could experiment with a link to a friend just for fun, but that is no significant band use. Unattended operation is more of a problem as well. We now need a special permit for anything that transmits beyond of the direct control of the operator. Presence of the operator while the gear is operating is no longer sufficient. Such special permits are given only for fixed frequencies and only in certain bands, and they also cost money.

Re: [44net] a common vendor neutral hardware/software stack for 44net. - was Re: hardware vs. software

by kb9mwr＠gmail.com

I was thinking the same thing. If it's a data transmission then yes obviously the bandwidth rules apply. If it's an image transmission then a different set of rules apply. If its a spread spectrum transmission then 97.311 applies. The problem is defining what you are transmitting. http://www.qsl.net/kb9mwr/projects/wireless/70cm-ATV-HSMM.html As for chewing the the band. You really have to look at it on a case by case basis, geographically. Where I live, 70cm is pretty dead, so a 5 MHz wide signal isn't a big deal. 15 years ago a guy was playing with analog ATV and that really did rip up the band, as it had no real filtering, and at the time the band was active. >97.307 doesn't apply to FHSS or DSSS. The applicable section is >97.311. Anyway this isn't the place to discuss rules in my opinion. However if we keep connecting slow speed conventional radios to the amprnet, then it will continue to be what is has for the last 20+ years. I am glad to see some people thinking out of the box, and exploring different technologies. Getting back on topic, I read there was a recent presentation titled "Providing authenticated amateur radio services on the Internet", is there a paper or video available for those of us who didn't attend?

For example, the presence of WiFi in the 13cm band (we have 2320-2450) already resulted in a ban to use 2400-2450 because of WiFi interference. The same will probably happen on the 5.7 GHz band now that it is becoming more popular for WiFi. 70cm is only 10 MHz here and part of that is already allocated to other services and we are only secondary to them. 1240-1300 we are going to lose when Galileo (the European GPS) is becoming deployed. Only a small segment for DX will probably be left (1296) The more a band is attractive for other services, the more likely we are going to lose it soon. The much higher bands will remain availble for now, but they are not as attractive. Rob

a common vendor neutral hardware/software stack for 44net. - was Re: hardware vs. software

by Eric Fort

It would seem Linux and Ethernet whatever architecture it's running on would seem to be the best solution available for routing Net44 at the moment and it works well. a standardized plug and play package of hardware sold by your local candy store would be nice but we're only partially there. Being that 44NET/Amprnet is supposed to be a RADIO BASED IP NETWORK (or at least interconnected islands of RADIO BASED IP NETWORK) we seem to only have half of a standardized solution to offer. It seems that we have forgotten the RADIO part. Given a live piece of cat5 with bits on it that I wish to have show up elsewhere what can we offer to the average ham that can go on the tower with Ethernet in one side and an antenna on the other, especially something standard enough that a local group can set up a network with? The only thing I can think of that even comes close is the professional grade 802.11 hardware that's out there. (much of the consumer stuff lacks the configurablity we could really use such as power control and timeouts). I might propose that we standardize the RF interface for AMPRNET on an agreed physical layer (of 802.11 unless something else is proposed and made quickly and cheaply available) and a relatively standard stack of hardware and software be put forth as a package that could be turnkey deployed by interested parties. What would others think of embarking upon such a project as a group? who might be interested? and what might we offer? (PS. I know of at least one manufacture of gear that would be quite happy to mod a standard product or products so as to have them better fit the amateur radio band plan and channels on a couple of our microwave bands as well as make provision for the ability to get significant QRO above the 25-30dbm out that seems standard. This in production batches maybe as low as lots of 100 units) Eric On Fri, Jun 28, 2013 at 1:32 PM, Michael E.

MikroTik is just as much of a closed platform as Cisco/JNPR/ALU/Fond-cade/etc. Cisco is ubiquitous, to a lesser extent Juniper (though I have to favor ALU for MPLS/core!). I'd say what we need is an open standards based solution that works across linux/cisco/jnpr (maybe an o-series? :) Something custom protocol wise to tie the 44net together is not ideal either as we cannot expect the big router vendors to support amprnet protocols. I know I'm able to slap a 1ru router (ie c2[6-9]00) in lots of places with good connectivity I could never put a server. I belive there is a way to do this via NHRP with BGP. I know I have a customer doing something like this.

DMVPN routing for 44/8 subnets

by jesse＠hindmarsh.cc

I am working on a lab design to add some flexibility and test other connection methods to the 44.0.0.0/8 network. I currently have a Linux gateway running rip44d for my main connectivity to the other 44/8 subnets. I have setup a Cisco based DMVPN where I can route other subnets to and route back to the Linux gateway for access to other subnets. This configuration also allows access from the public Internet to the allocated subnets via a Linux gateway. I have a diagram with a working layout and is in testing now. I am looking to see if anyone might be interested in connecting up to my cloud and see what and if any problems we may encounter. I use a very similar setup with my customers and there are some distinct advantages: - The end user would only need an internet connection and a Cisco DMVPN capable router. I have used 800, 1800, 2800, 3700 series Cisco routers. - The DMVPN works when you plug the Cisco router into a direct Internet or NAT connection. You can plug it in at home behind your Netgear home router, use DHCP and a private address on the router "public" interface. - Many subnets can be routed through a single Linux gateway and distributed easily. - No issues with dynamic IP address from your provider. If you are interested or have any comments or suggestions, take a look at the network diagram I made at http://www.hindmarsh.cc/images/wc3xs-ampr44.png 73 de WC3XS - Jesse

I learned the Cisco stuff myself from the manuals, have no CC certifications. I converted our existing network at work from leased lines to VPN some 10 years ago over Internet using DMVPN and it worked very well. (now we have dedicated lines again, but that wasn't affordable at megabit speeds 10 years ago) I suggested DMVPN before on this list, and I still think it could be a good option at least when an open implementation is available. I don't know if it is today, it has been in the works for some time. (the specs are open) In the performance class we are operating in, "hardware based" is not really required. A suitable box (processor and ethernet interfaces) and software (e.g. Linux plus some usermode tools) can do the same thing. I run IPsec tunnels between Ciscos, between Linux boxes, and between Cisco and Linux, and it is all inter-operating well. Of course we don't want to tie outselves to "only Cisco". But a solution where Cisco and open implementations (on systems like Linux and BSD) inter-operate is a very good thing. IMHO we don't need to consider compatibility with DOS (e.g. JNOS on DOS) as critical anymore. Rob

It is like what you have with a JNOS or Linux route importing encap.txt all the time, but without the hassle. Other VPN solutions are usually hub-and-spoke, where all internode traffic goes through the central hub. It is like connecting to net-44 by tunneling everything to 169.228.66.251 instead of loading a routing table. Rob

Re: [44net] Basic help needed with Linux and rip44d

by lleachii＠aol.com

Jesse, Take a look at my startup script at http://44.60.44.13/startampr It seems you have a similar setup, although one line of your configuration seems incorrect: ip route add 44/8 via 169.228.66.251 dev tunl0 onlink src 44.64.192.253 You should remove this route, it's invalid inside AMPR. You should not reach 44.0.0.0/8 via AMPRGW (169.228.66.251), you should reach each subnet via its gateway WAN IP address, as populated by rip44d. The return packet would come in the same manner, via their 44GW that has a route configured for you. My router: @kb3vwg-001:~# ip route get 44.64.192.253 44.64.192.253 via 24.229.88.252 dev tunl0 src 172.31.255.254 My route table shows: 44.64.192.0/24 via 24.229.88.252 dev tunl0 onlink window 840 73, Lynwood KB3VWG

Basic help needed with Linux and rip44d

by jesse＠hindmarsh.cc

I have followed the instructions on the wiki pages to the exact detail, and am having issues with the setup. I am at the point where I can receive routing updates but cannot send any data over the tunnel. I am not the best when it comes to Linux but have a better understanding of networking, routers, and routing (Cisco). I have eth0 on a public address. I have eth1 on 44.64.192.253/24 I have tunl0 on 44.64.192.254/8 I am running Ubuntu 10.04 on VMWare. 1. When I create the tunl0 interface with the class A netmask, how is rip44d using this and where does the tunnel "endpoint" get defined? (remote endpoint address?) 2. I have the Linux machine running rip44d and another linux machine on the same assigned 44.64.192.x subnet. I can ping between them until I bring up the tunl0 interface. If I down and up the tunl0 interface, I can ping as expected. Can anyone explain this behavior? 3. The tunl0 interface is registering collisions equal to the number of packets transmitted. I cannot find a reason why this is happening. Thanks in advance, Jesse

Jesse, Here are my notes: http://www.qsl.net/k/kb9mwr//wapr/tcpip/rip44d.html The endpoints are populated by the RIP routes that are received. You can run the dameon in verbose mode, and periodically check how the route table is being manipulated with the command "route" As for why you can ping two machines on the same subnet, it sounds like a conflicting route. Again what does "route" show you? Steve, KB9MWR

VPN access to AMPRNet using amateur X.509 certificates

by Heikki Hannikainen

Hi, The AMPRNet might be more useful if it had: (1) more services which would be interesting to hams (2) more access to the AMPRNet Tonight I tried to attack (2) a bit. Access to the AMPRNet over the Internet could maybe be made easier to hams by allowing them to connect over VPNs instead of setting up their own IPIP tunnels at home, or trying to find a working radio gateway. After getting a VPN running it might be easier for them to set up a radio gateway, or some services. As discussed on the other mailing list, VPNs are easier to get up on NATed residential networks than IPIP tunnels. Setting up VPN user accounts and maintaining them can be a pain. It doesn't take a lot of weekly or monthly maintenance work to run a VPN service, but it can be a major pain to manage an user account database for thousands of hams and check if your users around the Internet are, in fact, licensed. It turns out that ARRL's Logbook of the World has already given out cryptographic X.509 certificates to 57334 amateur users, after verifying their license status against the FCC database (they send a postcard with a random token code to the FCC-listed snail-mail address to make sure they give the certificate to the right guy) or after looking at a paper photocopy of a license + a photo ID. I had to physically mail in a photo of my ham license and my driver's license and wait a couple weeks to get the cert. If they can get 50k contesters and DXers to work with certificates, maybe certs can work for the AMPRnet, too. Technically, we can validate if a VPN user is in possession of one of those certificates and the respective private key. Politically, K4JH asked the ARRL guys, and they said that they don't mind if we use them for other ham authentication needs. We can start accepting other CAs too once they come around. I plan to help SRAL, the Finnish amateur radio union, to set up a CA within their web site (they already have user accounts for members). I know ARRL isn't for everyone, but smaller clubs could set up CAs too, or even commercial entities - as long as we trust them to do the license validation in a proper manner. Tonight I hacked up an OpenVPN setup which authenticates users with LoTW certs, and wrote a little documentation: http://wiki.ampr.org/index.php/AMPRNet_VPN What do you think? Technically, it seems to work - try it out if you like. It's not very straightforward to set up, but the license validation is pretty strong, and running the service shouldn't be a lot of work. There can be many VPN servers around the world, serving the whole customer base (VPN servers do not need access to any central user database, they just need the certificates of the trusted CAs). With a little Dynamic DNS magic, you could get a oh7lzb.vpn.ampr.org hostname on DNS within a few seconds after connecting (I've got code for that in another project). (Yes, eventually certificates need to be revoked after they accidentally get into wrong hands, or ham licenses are revoked. Technically that can be done using CRLs and/or OCSP, but ARRL apparently does not do those yet. Maybe they will, if the need arises. We can also set up a blocked certificates list of our own.) - Hessu, OH7LZB
