Dynamic IP Gateway problem.
by Demetre SV1UY 17 Aug '13

17 Aug '13

Hi all, I have setup, after many years of absence, our AMPRnet GATEWAY in Athens, running in a LINUX BOX. I have a dynamic IP here which rarely changes and up to now I had access to several AMPRnet hosts. Yesterday I had to reset my router (TL-WR1043ND running DD-WRT) and I lost connectivity. Checking http://portal.ampr.org I can see that my new Internet IP has been updated (it takes about 1 hour I think). Problem is that now I cannot ping gb7cip.ampr.org or any other AMPRnet host I could before? I can see that rip44d is doing it's thing using "tcpdump -i tunl0". How long does it take for AMPRnet to be informed after a change in Internet IP (nor 44net IP)? It has been more than 12 hours since my router got it's new IP and no joy yet! Any ideas guys? -- 73 de SV1UY Demetre Ch.

Portal DNS requests
by Blaine Forbort 16 Aug '13

16 Aug '13

I was just curious, is the portal's DNS request page up and running, or do I need to try to contact my coordinator directly? I'd like to add a couple of A name records for my routing experiment. router-3.k1qv.ampr.org A 44.4.36.3 router-5.k1qv.ampr.org A 44.4.36.5 These will be the two routers that will be connected to my gateway via OpenVPN. Thanks for the update, Blaine, K1QV Sent from my iPhone

Anybody that knows about BGP & GRE, I was wondering if this would be useful for us to look into (I am not that person). http://www.rfc-base.org/txt/rfc-6836.txt Jim A.

Re: [44net] rip44d update

Michael, At this point, ampr-ripd (C implementation) is the best thing out there in my opinion. Hessu, wrote the rip44d, and that required Perl and a multicast package to run. So running this on a WRT54G, for instance was probably not going to happen. I'd like to think with the C implementation, this could be a reality. Also, I am not sure, but do think the C implementation stands the greatest chance to run cross platform. Hessu's perl one was kind of locked to Debian installs. Again, it's all so new, I personally haven't had they time yet to try it on a bunch of different platforms. I actaully am not sure why someone would go with amprd over ampr-ripd. Perhaps others can comment. Steve

Here are some random thoughts: It would be interesting or maybe helpful if the ampr.org name server did some statistics collection. These stats could be used to help prune dead records? I am not sure how resource intensive that might be however. It looks like you can use Cacti in conjunction with BIND. It is also important that we have some idea what is on the amprnet, what it used for. The Michigan Digital Radio group has some basic activity polling : http://server1.nuge.com/~drg/network.html Perhaps even something that can be installed on gateways that promiscuously monitors well know ports/services, and can be configured to report activity to a central page? If nothing else can the gateway portion of the portal have some additional text boxes, so folks can explain things a bit more like the old resource.txt?

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 12 Aug '13

12 Aug '13

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

Trouble setting static route with ampr-ripd
by Neil Johnson 12 Aug '13

12 Aug '13

I've been trying add the following route to my "44" table to insure that local packets get sent out the wireless interface. ip route add 44.50.128.0/24 dev wlan0 table 44 However, I can't get it to be added when the system restarts. Any suggestions would be appreciated. Thanks. -Neil -- Neil Johnson -N0SFH http://erudicon.com

When adding the route statement to the initialization sequence, make sure the wlan0 interface exists; don't put it too early in the sequence. Perhaps best to add it and its 'del' counterpart to the networking scripts that bring the wlan0 interface up and down, not to the rc-scripts? P.
