Re: [44net] Is AMPR still relatively active?
by Rob Janssen 19 Feb '17

> I am trying to get a feel for how active AMPR is today. This varies a lot by region. The old network (1200/9600 bps packet radio) is completely dead in most regions and what is left over in those speeds is usually only APRS, so unrelated to IP used in AMPRnet. However, in some places new networks are being built using WiFi technology. Much faster and much more usable. Plus there is tunneling and direct routing of the net-44 space over internet to interconnect those islands. Rob

Is AMPR still relatively active?

Greetings, I am trying to get a feel for how active AMPR is today. I am a software developer by trade these days and am relatively new to the hobby but not to IT / networking. Looking for a place to get involved and give back to the community. Regards, Jim KD8MTY Sent from my iPhone

You probably are not running a full VM (hardware virtualization with a standard OS running in it) but paravirtualization like Xen which runs a special kernel in the guest machine. This is popular for providing virtual webservers and other "cloud" servers. However, as those servers are normally not full-featured, the guest kernel is compiled with limited selections in the kernel config, and it may well be that exotic features like IPIP tunnels are not provided in that config. When it is your own system, you could opt to compile your own kernel and modify the config while doing that. It may be easier to run the IPIP tunnel gateway on a dedicated system, e.g. a Raspberry Pi (as I do myself) or router (e.g. a MikroTik using Marius YO2LOJ's method. Rob

Amprnet vpn

Shawn, I'm lost; but I guess my inquires sum up to: - Are you running a stock installation of Ubuntu, or is it a version offered by the Virtual Machine Provider? - How are you "receiving the route information" and what do you mean by "but that would be it"? Did you receive route information via rip44d and confirm it by typing: ip route show table 44 ? Have you been successful at getting rip44d to run as a service? If the routes are there, this indicates you may have already made great progress. Did you attempt to ping or traceroute any IPs from an interface assigned an AMPR IP? If so, did you receive a reply? In any case, this means you are receiving the packets at the VM. We need to determine if the tunnel interface Up. Please verify by typing: ifconfig If you used startampr, you should see an interface listed as tunl0, it MIGHT say IPIP or UNSPEC, but you will recall you configured it for IPENCAP (this is because the Linux Kernel module for both are the same). Also note the names of your other interfaces, as the names used in the script must also be correct. Since Ubuntu 16.04, the Ethernet interfaces were no longer named: eth0, eth1, etc. Since I used eth0 and eth1 in documentation, you must account for variations in your system configuration. The ifconfig command will be most helpful to that end. You can also assign an IP to tunl0 (a commented-out line in the script allows for that). Lastly, have you ever received a copy of startampr from me? If you're using a script from Internet, that might be your problem (earlier versions contained less documentation). The current copy is only available on AMPR at: http://kb3vwg-010.ampr.org/amprnet_docs/start_ampr_version2/startampr Since that presents a chicken-and-the-egg problem for you at this time, contact me off-forum and we can arranging for you to get a copy. - KB3VWG

Amprnet vpn

Thanks for the detailed reasponce. I have work with the 44ripd daemon and I was recieveing the route information but that would be it. In thr startampr script that is show, it tries to setup mode ipip and that is just something that I couldn't figure out how to get a ubuntu vm to run with. In the ubuntu host, the ipip works just fine and there is a module for it. But the module isn't in the VM and I dont see why. But I was told ipensec is what I'm supposed to be using? I have no idea how to route diffrent protocols....

Sean, If you are using the AMPR VPN listed on the services wiki site, it uses the allocation given to its operator. You MUST setup an IPENCAP tunnel, or have your subnet routed over the global Internet via BGP. You might be able to have your allocation directed to the VPN operator (callsign - OH7LZB) and then arrange for him to route your IPs to the tunnel connection you have established between him. Please be advised, out of all the options, this one is not regularly supported. In addition, your latency would be extremely poor, since you appear to be in the United States and the VPN endpoint is in Finland. Lastly, from what I observed, the AMPR VPN appears to be a Layer 3 VPN (not Layer 2). This means that more detailed configuration (on part of the operator) may be required to route multiple IPs to your VPN instance - my understanding is that the VPN is maintained on a volunteer basis. What issue(s) are you having getting "[IPENCAP] over to the VM"? I ran my AMPR router as an Ubuntu VM for many years before migrating it to an actual hardware border router running OpenWRT; perhaps I can assist. 73, Lynwood KB3VWG

AMPR VPN
by Shawn Bush 15 Feb '17

I recently setup a AMPR NET VPN with openvpn in a OpenVZ container due to the fact I couldn't figure out how to get IPIP over to the VM. My question is this, I have a weird ip a 44.x.x.x number and I want to be able to use my given IP of 44.102.204.32, can I route my IP over the given one from the VPN? I'm using Ubuntu in the container and the routing for the VPN is working just fine. I want to setup linBPQ32 with this IP and start routing this way if I can. I'm pretty good with Linux, but not so much with routing. I setup a ampr interface and gave it my 44.102.204.32 IP, but from their I am stuck. 73's KD8NCV Shawn Bush

What ports needed to open for IPIP ?
by R P 15 Feb '17

15 Feb '17

Hi there We got permission to use our local university network for ham radio We plan to connect our DMR repeater to this network (some ports needed to be opened to allow the repeater to connect to the server) In adddiotion i want to place a AmprNET IPIP gateway there The University protected by firewall no outgoing and no incomming packets free flow.. What should I tell the IT person to open in order to allow gateway to run ? Does Firewall have IPIP protocole definition ? if not ... what should they open ? Outbond and inbond and from /to UCSD 44 Net Router ? Please Advice Thanks Forward Regards Ronen - 4Z4ZQ http://www.ronen.org Ronen Pinchooks (4Z4ZQ) WebSite<http://www.ronen.org/> www.ronen.org ronen.org (Ronen Pinchooks (4Z4ZQ) WebSite) is hosted by domainavenue.com

The users get real addresses > but the infrastructure does not. I think precisely this is the reason why such addresses should be rejected: The user may have the wrong assumption that the address to be entered here is the address of the system terminating the tunnel, while in reality it has to be the internet-visible address that supposedly is NATted to the tunnel gateway. So, what happens in the local infrastructure does not matter. Rob

192.168.0.2 gateway
by Brian Kantor 06 Feb '17

I just spotted this entry in the latest encap file: route addprivate 44.74.0.128/28 encap 192.168.0.2 Unless you're doing something highly unusual, setting your gateway address in the portal to 192.168.0.2 probably is a mistake since it's not reachable from the Internet. - Brian
