For that I'm setting up a couple of nodes spread out of the netherlands which I want to interconnect over the internet (untill there is enough coverage). Each node has a radio and a pc with a baycom- or soundmodem setup (and maybe in the future these nice tnc-pi devices). I've been investigating how to do this. For the distribution over the internet there's ax25ipd. Documention is a bit sparse though. Also I could not find how to bridge the ax.25 device of the baycom/sound-modem and the network device brought up by ax25ipd. It does mention bpqether module but from the name (and the modinfo output) I concluded that it is for bridging over ethernet, so not for bridging between two ax.25 devices. Also I did not find anything like "ax25_forward" or so underneath /proc (like the /proc/sys/net/ipv4/ip_forward we have for ipv4). I think I read something about interfacing to TNC devices directly by ax25ipd but that won't work with baycom- and soundmodems. I'm capable of developing my own software, I wrote a network sniffer (in "sysopview") and stuff that creates raw-packets for IP, so how difficult can ax.25 be? My plan is: using pcap sniff each packet from the two network devices and then using raw sockets feed them to the opposite interface. Yeah or I could create my own ax25ipd alike program, that does not matter. My question is: apart from the design, is this the way to go? Should I indeed inject packets using raw ax25 sockets and retrieve them using pcap? Or also retrieve them using raw sockets? Or is there maybe even ready-made solution that I overlooked during the lengthy google search? regards, Folkert van Heusden -- Afraid of irssi? Scared of bitchx? Does xchat gives you bad shivers?
