DMARC
by Brian Kantor 04 Aug '15

04 Aug '15

It appears that comcast and yahoo have implemented DMARC mail filtering around the first of the month. This breaks mailing lists such as 44net. As a result, about a dozen people have had their mail from this list bouncing and they've been unsubscribed from the list as a result. This message won't reach them, but if you happen to hear from a former participant in this list who is wondering what happened, you might let them know that their ISP has broken mail filtering software in place that is blocking their participation. - Brian

I did (just as for N1URO) detailed tracing of the network traffic and although there is outgoing encapsulated IPIP traffic to his advertised gateway, there is no reply whatsoever. It is still unclear to me if there is some problem with the operation of the network, or a systematic bug in the scripts that some people use. This time I thought I could download a script and have a look, maybe I see some problem, but I cannot access the site from any address I tried... :-( Rob

What might want to be considered in future portal enhancements under the gateways details section is a checkbox for if that particular gateway uses 1)rip44d by OH7LZB 2) ampr-ripd by YO2LOJ 3) A munge script Really if nothing else for statistical purposes. I realize gateway ops could be listing this voluntarily in the gateway note section till then. It might also be a good idea to have another field to list the radio LAN connectivity speed. (So people know to go gently with broadcast pings and nmap) It might also be nice to list the BGP connected subnets somewhere on the portal. For those not aware, you can see that now by: http://thyme.rand.apnic.net/current/data-add-ARIN | grep " 44\."

I am running Marius' ampr-ripd version, routes show "proto 44" root@kb9mwr# ip route show table 44 <clip> 44.182.69.0/24 via 5.15.186.251 dev tunl0 proto 44 onlink window 840 44.182.83.0/24 via 95.76.237.2 dev tunl0 proto 44 onlink window 840 44.185.1.0/24 via 109.107.73.62 dev tunl0 proto 44 onlink window 840 44.185.4.0/24 via 109.107.73.62 dev tunl0 proto 44 onlink window 840 etc.. kb9mwr@kb9mwr:~/test/ampr/ampr-ripd-1.13 $ grep "proto" ampr-ripd.c * Observation: All routes are created with protocol set to 44 req.rtm.rtm_protocol = RTPROT_AMPR; Marius can you explain the purpose of that for us? I am not completely sold that is the problem, but at the same time I don't pretend to understand the proto 44's purpose either. Thanks. Steve, KB9MWR ------ Quote ------ Can everyone verify their AMRPRNet tunl0 route tables do not include the following value: "proto 44" This appears to have somehow entered some stations routing tables, the value should be "table 44" for routers using a separate routing table, as defined in STARTAMPR; or by using '-t' switch with RIP44d. The ROUTING PROTOCOL value "proto 44" is invalid for routing on AMPRNet, and I understand it should be zero (0) or unspecified. - Lynwood KB3VWG

From another internet address, I get a 403 error. How do you route to 44.137.0.0/16? Route from here to you is via a tunnel: 44.60.44.0/24 via 96.255.40.79 dev tunl0 Tunnel endpoint cannot be pinged, 44.60.44.10 neither. Packets go out into the tunnel, nothing comes back. Same problem as with N1URO. Rob

AMPRNet Munge script package

Folks: I am using a pretty old munge package. I looked on the wiki/portal but I could not find the scripts, just references to it. Is it hidden somewhere? Thank you, Assi

It is interesting to see that the implementation of home connections varies so much over the world. Over here there is a legal obligation to always be able to produce the name and address of the subscriber that owned an IP address at a certain point in time, and it appears that most providers have taken the easy way of assigning a fixed IP to each subscriber. DSL connections all have a fixed IP. Cable connections usually have an IP that is fixed as long as you do not turn off the cable modem for a few days or so. There is no hourly or daily cycling of addresses anywhere. Truly dynamic IP is only in use here on mobile connections, and often they are behind NAT so not possible to use an ipip tunnel on them anyway. I have implemented OpenVPN and IPsec on our gateway so those users still can get connected to AMPRnet. I would think that when your address really changes hourly, and you want to be on an AMPRnet tunnel, it would be best to arrange something similar, a VPN to a system on a fixed address. It should be easy to arrange for such a thing, e.g. with a group that share a cheap VPS for it that can also be used for mail, a webpage etc. Rob

So presumably something is wrong, but it may not be the same firewall rules. Those were probably applied to input, while this is something at output or a problem with the routing / rules. I think it worked OK before. Rob
