Re: [44net] OVA for ESXi?

I get all the way to the section where it says I need to run 'sudo ./findpass.sh', and it gives me output of 'Tunnel Socket: Setting SO_BINDTODEVICE: No suck device'. The instructions I am following are at: http://wiki.ampr.org/wiki/Ubuntu_Linux_Gateway_Example#Setting_up_the_Tunne… And I am to the section of ' Finding the password for AMPR-RIPD" The only section that had an issue during this process is the isc-dhcp-server will not start. I don't believe this should make any difference, other than if I have a client on my Ham Network that needs DHCP, but I plan to statically assign those devices.. so I believe that point should be moot. My installation is Ubuntu 14.04.4 LTS I only have 2 interface.. eth0 (outside WAN address from ISP. One of my /29 allocations) and eth1 (inside 192.168.44.0/24) I know enough to make my way around, but am not normally a linux guy!! Let me know what other info would be helpful to share out, so we can get this one going. Thanks guys!! -- Rod Ekholm kc7aad(a)gmail.com

OVA for ESXi?

Thanks for the reply's guys. Lynnwood.. I have Ubuntu installed and working on my network (outside address as to not have anything blocking right now!!), but when it came time for the box to listen to the AMPR RIP broadcasts, I never did see anything. The notes say to let it sit for a little bit.. I let it sit for two days before I got back to it! :) So.. I haven't been diligently working on it, that's on me. But something seemed to go awry. Dangit. That's on me toooooo!! :( I'll try and get back to it over the next few days, and report back again. But if there are any ideas off the tops of ones heads.. Hit me with your best shot.. Fire Away!! Thanks. -- Rod Ekholm kc7aad(a)gmail.com

Yes, but since the machine is a standard Ubuntu Linux Server machine, I'm not sure how an OVA will help you. You still have to assign your IP addresses, turn on routing, etc. per the instructions in the Wiki. In the time it would take you to transfer it the file, you could simply have the same thing by running the ISO on a fresh VM. Are you having issues with setup? 73, Lynwood KB3VWG

Has anyone built an OVA of a VM used for an AMPR Gateway yet? Or has anyone Exported their local VM that they would be willing to share? *Disclaimer:* Yes.. I realize it is easy to build a host(though my attempt so far has failed). But If someone has already put in the work to build a VM, I'm willing to piggyback in their expertise in what they've built. Thank you!! -- Rod Ekholm kc7aad(a)gmail.com

Re: [44net] AMPRNET latency in VOIP connections ?

That only works when you have made special arrangements (policy routing) to make sure the Echolink traffic is ALWAYS sent to the NAT device and never routed directly. See what I explained to Gustavo. > 2. have the server have two NIC cards. One with a 44 address and the > other a local non-routable which is then NATed ouot your public internet IP. That does not require 2 cards (you can put 2 addresses on 1 card), and it is basically the same as the policy routing method, in this case using the IP address as the base for the policy routing. In practice it can be more difficult to implement because you need to force the Echolink application to bind to the correct card address. Fortunately Svxlink can do that, but many other programs cannot. Rob

Look at our repeaters, e.g. PI2NOS It is registered on the Echolink system using its own address 44.137.72.130 (pi2nos.ampr.org). Therefore this problem does not occur here. > the incoming IP results 44.137.41.97; so I understand that the > internet server act as the real gateway in a similar way as our > ampr.org gateways. It function very OK! Yes, for "normal traffic" it works OK. But not for Echolink. This is because Echolink has a directory server that registers your repeater by IP address, and this address does not match the actual address. When you get connected by someone from plain internet, it works OK because the route back is through the same NAT router, where you have defined port forwarding for the 5198 and 5199 ports, and the users sees the same translated address as the Echolink system registered. However, when I connect from my address 44.137.41.97, the repeater or another part of the system thinks it is being clever and routes the traffic through a IPIP tunnel, the address does not get translated, and the connection fails. The quick way to solve it is to give your repeater some RFC1918 address (10.x.x.x, 192.168.x.x) so its traffic is always forced through the NAT router. Alternatively, you can setup some policy routing so the Echolink traffic is always sent to the NAT router, not routed directly. Then you can still use AMPRnet on the same computer for other things. The way we solved it here is by applying for BGP routing of our subnet, so our net-44 traffic is routed directly on internet and it is no problem to run an Echolink repeater on it. (the subject of this thread: will routing through UCSD cause problems with VoIP. yes it will, but we don't route through UCSD so we don't have that problem) Rob
