Can anyone suggest solutions for using an AX.25 port (TNC, soundmodem or whatever) remotely eg hooked up to a different computer. Here's two scenarios: 1. Computer A wants to transmit/receive on RF; RF port is attached to computer B; computers are on a local Ethernet together. +------------+ +------------+ | Computer A |----------| Computer B +-- RF port (TNC etc) +------------+ Ethernet +------------+ Runs application Has RF port eg XASTIR Computer A wants to work through B transparently; it wouldn't have to specifically mention B in its AX.25 packet path, nor would frames received back by B. 2. Same but computers are connected only via IP, not necessarily on the same Ethernet: +------------+ +--------+ +------------+ | Computer A |----------+ Router +-----------| Computer B +-- RF port +------------+ Ethernet,+--------+ Ethernet, +------------+ PPP etc. PPP etc. Runs application eg XASTIR Again the application on A would like to see a standard Linux networking interface and think it's connected directly to RF. On a related note, can somebody give me a good description (either here or a URL for) for BPQ over Ethernet? Is that part of the answer to #1? I think AX/IP (RFC 1226) is the protocol behind #2, but does linux (ie ax25ipd) do this already? Thanks, Hamish -- Hamish Moffatt VK3SB
