This is version 029 of the new AX.25 and NET/ROM code for Linux. It incorporates many enhancements since the last release, notably the rewriting of the connected mode IP code and the IP over NET/ROM code. The opportunity has been taken to add the G8BPQ NET/ROM extensions and to add BPQ Ethernet support. The latter has been much eased by the use of the new variable length header code by Alan Cox. To use the BPQ Ethernet option, first up the ethernet interface in the usual manner, the IP address of the interface is not that important but it will be required for the ARP table. Next create an ARP entry in the ARP table of type ax25 for the interface binding it to an AX.25 callsign, this callsign will be the callsign of that interface. By default BPQ Ethernet uses a multi-cast address, this implementation does not, instead the standard ethernet broadcast address is used. Therefore the NET.CFG file for the ODI driver should look similar to this: ------------------------------ cut here ------------------------------------ LINK SUPPORT MAX STACKS 1 MAX BOARDS 1 LINK DRIVER E2000 ; or other MLID to suit your card INT 10 ; PORT 300 ; to suit your card FRAME ETHERNET_II PROTOCOL BPQ 8FF ETHERNET_II ; required for BPQ - can change PID BPQPARMS ; optional - only needed if you want ; to override the default target addr ETH_ADDR FF:FF:FF:FF:FF:FF ; Target address ----------------------------- cut here ------------------------------------- The above configuration assumes that only BPQ Ethernet is being used. It is not possible to run IP over AX.25 on the BPQ Ethernet port. To simply route IP frames to (say) eth0 would create standard ethernet IP frames and completely bypass the AX.25 code. However it is possible to use IP over NET/ROM across a BPQ Ethernet link, the performance of such a system is very acceptable indeed. Jonathan Naylor G4KLX g4klx@amsat.org
