44.133.48.66 !!!
by Maiko Langelaar 12 Apr '14

12 Apr '14

Good afternoon, It would see that 44.133.48.66 is popping, snmpding, and other amounts of traffic from time to time to various ampr.org systems and doing so *without warning* type of thing. I just got hit with a bunch of SNMP requests, others have been hit with POP requests. Can anyone find out who the owner of that particular system or network is, so that I can contact the entity or person. Or perhaps a bit more draconian, can someone deal with it. Thanks in advance.

Linux Gateway Tutorial
by Neil Johnson 07 Apr '14

07 Apr '14

I'm trying to decide how to write a "How To" guide for setting up a Linux Gateway for the Wiki. I'm planning on basing it on the excellent guide found here (with Credit): http://marc.storck.lu/blog/2013/08/howto-setup-an-amprnet-gateway-on-linux/ But I'm wondering what level of Linux Administration and IP Networking Expertise I should assume. If I assume zero, it's going to be a looong guide, probably too long. Below is a link to the diagram I was planning to base the guide off of. AMPRNet Gateway Diagram - https://docs.google.com/drawings/d/1xAcMbROBpbuRFY0tVf1VdBrAP0ZQwTsE6Eqokn2… Comments welcome. Thanks -Neil

Pi bug for ipencap?
by Brian Rogers 06 Apr '14

06 Apr '14

Greetings; I've noticed recently after doing a package update on the iproute packages I can no longer configure my tunnel interface tunl0. Mainly I'm trying to reset the ttl to 64 for traceroute to properly work. Everything I've searched comes up empty. Here's what I see: root@gw:/usr/local/bin# iptunnel show tunl0: ip/ip remote any local any ttl inherit nopmtudisc root@gw:/usr/local/bin# ifconfig tunl0 tunl0 Link encap:IPIP Tunnel HWaddr inet addr:44.88.0.1 Mask:255.255.255.255 UP RUNNING NOARP MULTICAST MTU:0 Metric:1 ttl is stuck on inherit and MTU autoconfigs to 0. This I know is set by nopmtudisc however if I try to adjust things: root@gw:/usr/local/bin# ip tunnel change tunl0 ttl 64 ttl != 0 and noptmudisc are incompatible root@gw:/usr/local/bin# ip tunnel change pmtudisc mode ipip add tunnel tunl0 failed: No such file or directory Why would it try to ADD? the command is CHANGE. Has anyone else suffered this before and if so what was the fix? Thanks in advance. -- 73 de Brian Rogers - N1URO email: <n1uro(a)n1uro.ampr.org> Web: http://www.n1uro.net/ Ampr1: http://n1uro.ampr.org/ Ampr2: http://nos.n1uro.ampr.org Linux Amateur Radio Services axMail-Fax & URONode AmprNet coordinator for: Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, Pennsylvania, Rhode Island, and Vermont.

I vote routeable. My /24 is announced, can't say I really work that hard to keep my tunnels updated. I use my space to provide services to amateur radio and the internet. I just lit up an Allstar RTCM node and asterisk server for simulcast recently. -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net

If we give 44/8 back, then those of us routing 44 traffic over RF to other 44 stations get screwed, now don't we. :/ 44/8 is for amateur radio only. There are plenty of us using it. I have ports to both other 44 stations, as well as BPQ stations that can't use it. Beside, no one is mandating any station use it in their configurations. The beauty of *you* not wanting to use it is..... You don't have to. The beauty of *me* wanting to use it is.... I get to.

Can't add redundant AMPR gateway to portal
by Bart Kus 31 Mar '14

31 Mar '14

Screenshot This network (44.24.240.0/20) is available via both 209.189.196.68 and 198.178.136.80. However, I'm unable to list more than one point of contact. I realize this was probably a design decision at some point, but it doesn't seem like a good idea from a redundancy perspective. --Bart PS: If you're wondering why the image looks like crap, it's to satisfy the puny 32kB message size limit of the list.

marking and iproute2
by Michael E Fox - N6MEF 31 Mar '14

31 Mar '14

I've been told that one can use iptables (presumably the mangle table) to mark packets inbound on different interfaces and then use iproute2 to send the responses back out the same interface. Is anyone doing this and, if so, would you be willing to share how you do that? Thanks, Michael N6MEF

isn't 44net being a "full mesh" a misnomer? Is it even necessary?
by Eric Fort 31 Mar '14

31 Mar '14

It would seem to me that while due to the fact we are tunneling most everything we may have a logical full mesh but far from a physical full mesh. What does a tunneled logical full mesh really accomplish for us other than making things all the more complicated? Wouldn't traditional peering and routing done "the normal way" be much easier? I can see a valid place for nailing up vpn links and various tunnels, i.e. last mile access and tying islands together though something other than IPIP with links negotiated on a peering basis as needed, but what does a full logical mesh of tunnels give us? It seems that since it's built of tunnels and thus virtual rather than physical we just unnecessarily complicate the mess wherein the tunneled traffic and the tunnels themselves end up taking multiple and somewhat changing hops to get from one end to another. IP was designed such that I could hand a packet off and basically go, "ok, now it's your problem to deliver it (on a best effort basis)", thus I shouldn't need to know every conceivable route to every conceivable endpoint. What prevents us from using it that way? Eric AF6EP
