Good Evening Folks,
Is something going on with the gateway...????? I just noticed this today:
--- ampr.org ping statistics ---
92 packets transmitted, 72 received, 21% packet loss, time 91427ms
rtt min/avg/max/mdev = 33.320/41.448/51.167/2.890 ms
As opposed to:
--- aa6hf.ampr.org ping statistics ---
100 packets transmitted, 100 received, 0% packet loss, time 99146ms
rtt min/avg/max/mdev = 47.409/56.381/70.304/4.552 ms
Pings to my commercial IP (from my network at work) are 100%.....but pings to ampr.org (from my network at work) are showing dropped packets as well.

Hi,
My pings seem stable, although high at around 200ms, they are consistent.
Endpoint is in the UK

Albert,
Yes, something is wrong:
root@OpenWrt:~# ping 44.0.0.1 -I 44.60.44.1 -A -c 100 -s 22 -q
PING 44.0.0.1 (44.0.0.1) from 44.60.44.1: 22 data bytes
--- 44.0.0.1 ping statistics ---
100 packets transmitted, 79 packets received, 21% packet loss
round-trip min/avg/max = 66.029/66.446/69.157 ms
You all can test from my end: http://kb3vwg-010.ampr.org/tools/ping/php-ping44.php

Hi!
First I want to thanks the ampr group and especially G1FEF for providing me a /24 that I am in the process of being bgp annonce with a vultr vps in NJ.
If what I am about to talk dont fit in the group, please let me know, I will move this else where.
I am in no mean a network guru but I understand concept pretty easily. SO I am planning my /24 as this.
the VPS at vultr will use Bird to annonce the route, I will use only the default route provided by vultr.
>From there I created a dummy interface that have my /24 as its IP.
I then want to make a VPN server to distribute the net and ip to remote site I have that use a mix of hardwired and wireless connection. The routers are all edgerouter-x from ubiquity they will all eventually be interconnected by 2 sources, the hardwired provided by many ISP and the wireless that I am building as a redundancy. If one sources fail, the router will fall back to the other link. the prefered links will always be the hardwired, the wireless is the backup. (some of the links are 40 Km long, but most are 5-6 Km and the smallest is under 1 Km.)
>From those edge router I will have connection to the vpn and every router will have a dhcp server that will serve a part or the /24 like 16 ip for each site. (I have 3 site right now) and I will have fixed IP at each site for the repeaters and aprs gateways.
Now the configuration of the vpn is my first problem. should I have the vpn server listening on the ipv4 address of vultr or should I made it listen to the dummy interface?
I think this is juste the beginning of my quest!

Hi!
I asked a few months ago for a /24 so I could advertise it by BGP on a vultr server. I had receive a request to fill up a form, but for personal reason I was not able to pursue the project.
rewind to end of september and I redo the request, fill out the form and do everything in order, well I hope, but it was delayed cause the emails I was receiving kept going into the spam folder..
Sent a few email back to ask the status, if my form was filled ok, I had no answer. I am just wondering if I did something wrong or if the request is en route.
Sorry if this is the wrong forum to ask.

Hello 44net!
In our video call on Oct. 10, I heard from folks that they were
interested in more regular meetings and office hours.
So - let's give the office hours a try! I'll be online for two hours on
Thurs. Nov. 12 @ 17:00 UTC (10am PT / 1pm ET / 6pm BST).
Link to the video call will be posted in advance.
Looking forward to chatting with you soon!
All the best,
Rosy

> Is the European Asterisk/DUNDI/AMPRNet voip network you describe
below documented somewhere? I tried to google around but did not find
anything.
There is some scattered information, e.g. this at DB0WA:
https://www.afu.rwth-aachen.de/projekte/hamnet/anwendungen/sip-telefoniehttps://www.afu.rwth-aachen.de/projekte/hamnet/infos-fuer-betreiber/dundi-n…
This page also describes a crawler for such nodes and shows a map, but I
think this crawler
is dead as the map shows information from last year and has not been
updated since.
That is probably related to the renumbering of the German/Austrian network.
(as you know these networks ended up being in the part that was sold)
I don't know if the network itself is still actively maintained or if it
is just an experiment that
is not interesting to its inventers anymore and just keeps running until
the servers crash,
someone turns them off, or a disruption such as the renumbering occurs.
At least locally
for me it works fine, but I use it mainly for calls to one other person
who is on the same
PBX as I am.

I don't know how wide its coverage is, but here in Europe we have a network
of Asterisk PABXes on AMPRnet that have interconnecting trunks between them
that allow you to call anyone on the network on their roaming number.
Phone numbers are allocated based on the callsign (using a scheme based on
the letters printed on DTMF keypads. based on my callsign, my phone number
is 713210234253 for "1st letter on key 7, 2nd letter on key 3, digit 1, 3rd
letter on key 2, 2nd letter on key 4, 3rd letter on key 5" giving PE1CHL ).
The DUNDi trunk protocol distributes the information about the home server
for each number across the network, so all Asterisk servers know how to
route the calls.
It is easy to host a conference on one or more of the Asterisk servers and
have everyone dial in to that. There is such a conference running on my
local
server where I have my IP phone connected all the time.
I think such systems can do low-bandwidth video as well, but I have never
tried that. For audio it works perfectly.

I agree that would be much more efficient than having the basic star-type
structure where everyone gets the same stream from one server. That
would be one thing that could be implemented in AMPRnet to show the world
that it really has advantages.
For phone quality voice and the number of attendees we would expect, running
this over AMPRnet in the star configuration should be no issue.

Hi 44net,
Thanks again to everyone who joined us on Saturday's call. I really
enjoyed getting to share about what we've been doing with all of you.
A recap of the meeting has been posted here, including links to slides,
survey results, and the chat. We've also provided answers to all of the
questions brought up in the chat, to make sure we got them all covered.
https://www.ampr.org/recap-ardc-44net-oct-10-community-call/
The one thing that's not posted is the video - we are having an issue
with the file and will post it as soon as it's resolved. Thanks for your
patience!
In the meantime, please enjoy rest of the materials and written Q+A.
Looking very forward to the next call!
All the best,
Rosy
