Re: [44net] Echolink proxy/relay hosting

For everyone's info: I have updated the file at http://pe1chl.nl.eu.org/Softw/elproxy.tar.gz (also available on www.pe1chl.ampr.org on net44) to include an init.d script example and a logrotate.d config file. Everything else is unchanged. I welcome corrections or suggestions for changes in the README file when something is unclear. Make sure you follow everything written in the file as it is now. (especially the part about sysctl and the proxy_message logging) I should probably some description of what proxies and relays are and how they are used, that was already sent to this list however.

GW (amprgw, gw.ampr.org) downtime tomorrow evening

by Brian Kantor

UCSD is swapping out some networking equipment and amprgw (aka gw.ampr.org, 44.0.0.1) will be unreachable for a while starting around 7pm Pacific time Thursday (tomorrow). It should take only a few minutes, but as both the connection and configuration have to be transferred to the new equipment, there is always the possibility that it will take longer or something else may go wrong. - Brian

It affected our gateway since a script that downloads the DNS zone when modified got stuck, halting a cronjob script that also performs other maintenance tasks. Modified with some more safeguards... :-) Rob

Remember when we ware able to simulate a MAC with a few roms and a ST? 😉 > OK, back to our regular programing. Think we got back way too far on memory lane for this mailing list 😉 I still have a Mega ST4 with harddisk cabinet and original monitor sitting in a spare room but it rarely gets switched on these days. (those were the newer pizza-box style ST and disk. the disk cabinet in fact is a 44MB swappable plus a fixed disk) This one is fitted with an ethernet adapter I made (a PC ethernet card and adapter board to the internal bus) and I added a driver for it to KA9Q. However, the card has BNC and AUI only and I don't have coax ethernet anymore. Should have an AUI to RJ45 adapter somewhere. Also in storage there is a Mega ST2 with an 8-port Z8530 SCC card that we used for years on a major network node (TCP/IP and NET/ROM)... (of course I had a 520ST as well but that one has long been scrapped) Rob

When I got access to "the Internet" (of course via dialup modem too) I already had a running Linux system with native TCP/IP networking. I installed that in december 1992 on a 486/33 MHz with 16MB RAM. And a QIC cartridge tapedrive, so no messing with floppies. The internet became available for the general public in 1993 here, I joined in 1994. But of course I had been using TCP/IP since 1988 using KA9Q NET on the Atari ST. Rob

An apology for the Internet from the people who built it

Although not directly related to AMPRNet, I found this article quite interesting: http://nymag.com/selectall/2018/04/an-apology-for-the-internet-from-the-peo… - Brian

I agree it is probably not a good idea to run proxies or relays on a network only connected via tunnels. That would pose a load on AMPRGW. In that case it would be better to run them there. But other volunteers in that area have now stepped up. > I used the Java JAR that was available form EchoLink (I understand you > have a C program). I also used the Linux version, but the EchoLink > Validators stated that should not be used without permission (and only > for conference servers). The Java version uses lots of resources... The C program was written to mimic the Java version closely but in a more efficient way, both because it is in C and because a single instance can run multiple proxies. Later I received the C source of the relay program from EchoLink and merged its functions with the proxy program so these can both run on the same system. This is in full agreement with EchoLink, and they very much welcome the hosting of proxies and relays around the world to help users that are on limited internet connections or are not proficient in configuring port forwarding on their routers. Fortunately in our circles we have people who understand the internet and its protocols. (vs the applications that are now called "the internet") Rob

As you know, I don't agree with that. We should not segregate our addresses into different classes and force everyone into some class depending on what they want to do. It is a stopgap measure that will lead to endless changes and work, and it isn't even clear what "internet based amateur radio services" are exactly. For example, our repeaters are on Echolink on their AMPRnet address, they would be such services, we would have to route part of that space deeply into our network to get "special" addresses all the way there. Not going to happen! At the moment I am in contact with the Jonathan from Echolink and he is interested in setting up more relays as his existing relays in the US are getting overloaded. (he has temporarily moved some US users to our relays in Amsterdam) I think now that this is under change we could suggest moving everything to AMPRnet and it should solve the NAT problem there is now. Maybe the directory server could have both an AMPRnet and a public address to resolve remaining issues. Rob

When I saw the list I immediately thought "those aren't the people who built the internet!" Not even the world wide web. Maybe Web 2.0.
