It is normally runs for months on end until I need to reboot the machine, but in that case it just crashes. I know it must be a bug somewhere in the years old naive TCP implementation but I have not been able to locate it yet. Until then, I have just blocked you in the firewall. Just to let you know that actions like this (and the one Ronen proposed) *do* cause damage to others. Rob

Re: [44net] was Uncle "google" in hamradio network ? Repeater linking
by Steve L 26 Mar '16

There isn't a whole lot of entries in the wiki services list. I am not sure how many net 44 users are on this list and or know about that. I personally find wiki markup coding a pain as its not native to me. Another thing is maybe some people would rather share service details after a portal login rather than somewhere that gets scraped by google. To me it sort of make sense to briefly explain what your doing in the network allocation area and/or gateway areas of the portal. In my quest, one thing that caught my eye was this Michigan repeater linking/microwave project. Mostly because they are closer to me in Wisconsin. https://w8cmn.net/tiki-index.php?page=Mi6WAN-MAIN I recall someone on this list no that long ago from overseas was doing a similar project with Asterisk/app_rpt and 802.11. Elsewhere (reddit/slashdot) I recently read about the Mid-Atlantic IP Network ( I think they aren't using 44net though), same type of thing. I like the idea, and have been looking to try the Asterisk/Allstar RTCM to add a voted receive site, but transported over a microwave IP link. We just did a tower climb today here in Wisconsin and replaced some damaged 802.11 gear. And had an offer from a broadcast group for some tower space. I am hoping 2016 is the year things take off a bit locally. Steve

Thanks for the info. Looks like the info I need to use it for our purposes. Some time back there was a resource list that Jim Fuller maintained that was handy to list what was all out there. >HiHi >Not the whole one, for shure. >Just your "local area" and then report to the yacy network. > >Have a look here after google translated it for you ;-) >http://www.amateurfunk-wiki.de/index.php/Suchmaschine > >73 >2MIC

I just recently completed an nmap of the routed portions: http://kb9mwr.ampr.org/public/nmap/030516routed.txt http://kb9mwr.ampr.org/public/nmap/030516nmap.txt I did the same thing a few years back but there was that IPIP,<-> BGP problem I too have yacy installed. I just started it back up. I am not to familiar with it, how do it get it to crawl the amprnet?

No, and I'll admit that. That is why I'd like to hear more about how to configure yacy. But since there isn't a search engine or otherwise way yet to get an idea what is on the amprnet and what people are doing on the address space, I couldn't really think of any other way. The links below will only be active for a short time, as it's really only meant for 44net folks to get an idea.

Re: [44net] Testers/Consideration/Inquiry - Coordinating the Private AS Numbers
by Rob Janssen 25 Mar '16

I don't understand your consideration of "moving from a star to a mesh". We ALREADY have a mesh! There is no load to be removed from AMPRGW other than the routing from/to internet for those that are not directly BGP routed on internet. When you want a solution for the "single point of failure" for RIP announcements, the simple solution would be to deploy a second RIP annoucer elsewhere, that sends the same information as AMPRGW, and takes over when AMPRGW does not send those announcements. Of course it still needs to be fed with the same topology information, so it could be tricky to get a solution that does not have any single point of failure, but your solution of doing BGP over tunnels instead has such information embedded in the static configuration of all the peers, which is even more difficult to manage. So it is not really clear to me what such a change really would achieve what we do not already have. What is the status of usage of AMPRnet addresses in HSMM? In the past they used RFC1918 addresses that were automatically allocated. I believe newer versions can use static addresses that could als well be from NET-44. Is this already in wide use? Rob

> a.) then how would a new or offline IPIP station connect if AMPRGW were DOWN at the time? This is not a task of AMPRGR but of portal.ampr.org > b.) then how do I get routes from AMPRNet without a DIRECT CONNECTION tunl0 connection to AMPRGW? As I wrote is is possible to deploy a second system that does the RIP announcements > c.) what if I can directly reach 2 or more AMPR subnets (but not the Internet)? We already have a large network of radiolinks running here in Europe, and I think also in some other areas of the world. It does not rely much on the internet, except for DNS. I download the ampr.org DNS zonefile daily so I have it available when we are offline. > a.) AMPRGW is currently the only route announcer (but you address that elsewhere) I think it is important because it is the only weak spot I can see. > b.) Next, it's not the ideal route to all subnets Why not? > c.) this solution addresses the possibility of redundancy to other subnets, as well as AMPRGW I don't understand. There already is full redundancy. We have a full mesh. > In planning, it would probably be an alternative to IPIP, and not a replacement. Ideally, there could be a few regional gateways, other stations connecting to one or more regional gateway and to other end-user gateways. That is how we run the network here. What is your proposed change? Rob

DMZ or not?
by Rob Janssen 24 Mar '16

> I host a 70cm echolink node and did not need to place that PC in the DMZ. > I did need to forward UDP ports 5198 and 5199 to the PC running echolink. I don't > remember whether I also forwarded TCP port 5200 or whether that "looked after itself". You are right, only forwarding 5198 and 5199 UDP is sufficient. The echolink program also makes outgoing connects to port 5200 on the central server but you normally don't need to open or forward anything for that, it is just the normal outgoing NAT. (there are instructions that mistakenly mention port 5200 to be opened, but the program is not even listening on that) Rob

D-Star
by Pedja YT9TP 23 Mar '16

23 Mar '16

We are planing on setting up D-Star gateway, so I am reading all I can about it. Here is exception form one tutorial regarding this: "The router for the D-STAR gateway must support a LAN address of 10.0.0.1, with a full class ‘A’ LAN (subnet mask of 255.0.0.0)." Is it just me or this is really strange to force this IP range which will conflict with number of private networks, especially when there is 44net dedicated for ham radio use? Pedja YT9TP
