I have LinuxNode 0.3.0 installed and it disconnects the users calling via AX.25. It reports a message in syslog: ... Jul 13 16:27:21 tequila ax25d[6479]: AX.25 CT1BPT-8 (uhf1) node Jul 13 16:27:22 tequila node[6479]: Unsupported address family 40560 ... I have the following config: kernel 2.2.9 glibc 2.1.1pre3 libax25-0.0.5 ax25d from ax25-tools-0.0.3 I had this problem even with ax25utils-2.1.42a. It worked well when the kernel was 2.0.36. After upgrading kernel, LinuxNode (from ax25util-2.1.42a) answered AX.25 calls only sometimes. The other times reported the same error in syslog. So, I can only receive via TCP/IP. My computer is an i486 with SCC Card (modem1: 1k2, modem2: 9k6) and an ethernet card. Anyone has this problem? 73, Jorge Matias (CT2HBZ)
