4 years ago This was discussed on the OpenDV mailing list. Essentially all APRS-IS interactions now go via the APRS Gateway which received UDP messages from the gateways and sends them via one TCP stream to APRS-IS. The reason for this was the load caused on APRS-IS by all of the gateways operating independently. That is why the UDP stream is not compatible with APRS-IS, it was never meant to be. It is important that people subscribe to OpenDV@groups.io so this sort of confusion doesn't happen. Jonathan G4KLX

I recently moved to the latest version of ircDDBGateway. My old gateways had to be updated from good old CentOS5 to Raspbian and it was time to update all applications. After I installed the latest version from the GitHub, last changed a few month ago, reporting 20190621, I found that APRS does not work anymore. One reason was that I obviously missed some changes, like the names in the config changed from aprsHostname to aprsAddress, the aprsPort for UDP usually has to be 8080 instead of 14580 for TCP before.
