In another thread, it was said: >> everyone in the mesh ought to be running a dynamic routing protocol thus >> increasing redundancy and reliability. >This is a good idea. I'm not up on the latest RFCs concerning routing in >tunneled (VPN, GRE, etc) networks. Do you have a recommendation? I am not an expert to answer this question, but I have stumbled on an emerging method for routing that has remarkable similarities to threads here. Along with the connections/associations I list below, it is experimental communications, and I believe we (Hams) have something to contribute. RFC 6830, LISP (Locator/ID Separation Protocol - see [http://www.lisp4.net/] ) decouples Location from unique IDentifier in IP addressing. I first saw the need for this concept with APRS messaging, but that is for another group. "LISP follows a network-based map-and-encapsulate scheme ... both identifiers and locators can be IP addresses or arbitrary elements like a set of GPS coordinates or a Mac address." {or call sign?} The LISP Papers at [http://blog.pattincon.com/lisp-papers/] seems to be a good place for me to start to understand the application of this protocol. It is implemented in recent versions of Cisco IOS/NX-OS (out of my reach at this time) and LISPmob (Mobile Node) at [http://lispmob.org/] runs on OpenWRT/Linux. I am working on experimenting with something from here. Peace, Jim A. KB3TBX

--- Quote --- For some reason, I cannot get it to receive the 44.0.0.1 -> 224.0.0.9 transmissions. The socket is listening on port 520, when I trace tunl0 I see the packets arriving every 5 minutes, but the rip44d (running with -v) remains absolutely silent. Any idea what that can be? ------ The first thing that comes to mind is something wrong with the tunl0 netmask.

Re: [44net] Something simple

by Rod Ekholm

Pedja, If I add the encap.txt file you provided (realizing is is truncated..) and adding it to my files list in my router, and running the txt file you provided as a scipt in my MT, it does nothing. Is this the intended method of your files? i see the script count increment, but I don't see any routes get added. In the first line of the script file, I edited the IP Address to be my local (inside address). Should it be the inside address, my outside WAN address or my AMPR address? Thanks for clarifying, and great job, if this works! -- Rod Ekholm KC7AAD

Re: [44net] Who is teqsys.net and why is he sending me RIP?

There is an email address for him on QRZ too. I sent an email to Hugh, he confirmed he has removed his RIP transmit configuration now, and teqsys.net should not be sending those packets any more. - Hessu

Re: [44net] Radio-based networking

by Paul Delaney - K6HR

Same here, all dressed up with nowhere to go! I maintained 6 radio ports for quite a long time utilizing HF/VHF/UHF 1200/9600/PACTOR3, even satellite. No users. No more fun. I eventually reinvested that money in other areas of the hobby. Judging by the replies so far I think it's fairly safe to say there is little to no tcp/ip over radio in use anymore.

------ Quote ------ Is anyone actually using the network over radio at this point? Could you supply some details? We had been using the 44 net space and TCP/IP over radio (1200/9600) for many years here in Wisconsin. We even ran Webservers on those links. This made the 1999 CQ and CQ-VHF magazine. Our original packet organization's (WAPR) webpage was accessible via radio. http://www.qsl.net/kb9mwr/wapr/ Now most of the 1200 baud portions of the network are dead, and only a few have moved on to 802.11 options. I and four others in Green Bay have been mostly doing remote backups using rsync over 802.11 for several years now. A few years back I ran a PBX with a 802.11 trunk to my friends house.

IP Protocol 4 in DD-WRT and rip44d script

by Demetre SV1UY

Hi all, Is anyone using a DD-WRT router (I use a TL-WR1043ND with DD-WRT) for his/her AMPRnet GATEWAY 44.154.0.1? I have the following problem here. I have included support in my DD-WRT Router's IPTABLES for IPIP (IP Protocol 4) with the command "iptables -t nat -A PREROUTING -p 4 -j DNAT --to 192.168.250.66" in it's Firewall, but this does not seem to work. I wonder if I need to also port forward UDP port 520 to the same IP, but I don't think so because I think rip44d uses UDP port 520 for outgoing packets only. When I put my GATEWAY's ethernet IP (192.168.250.66) in DMZ then rip44d works fine, but then my AMPRnet GATEWAY is really exposed and I need to write an extensive IPTABLES SCRIPT. Is there a way for rip44d to work behind NAT? Is my "iptables -t nat -A PREROUTING -p 4 -j DNAT --to 192.168.250.66" command enough for my DD-WRT or am I wrong? Could anyone help please? 73 de Demetre SV1UY IP coordinator for AMPRnet in Greece e-mail demetre.sv1uy(a)gmail.com
