| - | TBC | + | ===== Individual interfacing from AX.25 to TCP ===== |
| + | If you don't like the centralized way of connecting your old AX.25 transmitter, you can also setup you own interface from AX.25 to TCP. A Raspberry Pi is enough to do so. | ||
| + | |||
| + | The following steps are needed: | ||
| + | |||
| + | - Connect your RPC card by means of a USB-2-Serial converter | ||
| + | - Setup the ax0 kernel network device with kissattach. Edit ///etc/ax25/axport// before. | ||
| + | - Install xinetd | ||
| + | - Add the file below to a file in ///etc/xinetd.d// | ||
| + | - Use the DAPNET-Proxy to connect yourself with a DAPNET-Node | ||
| + | - Get your new transmitter registered into the DAPNET network (see above) | ||
| + | |||

| + | # description: Example AX.25 Interface to DB0SDA C9000 | ||
| + | service rpc_db0sda | ||
| + | { | ||
| + | disable = no | ||
| + | type = UNLISTED | ||
| + | port = 19999 | ||
| + | id = funkruf | ||
| + | socket_type = stream | ||
| + | protocol = tcp | ||
| + | user = root | ||
| + | wait = no | ||
| + | server = /usr/bin/axcall | ||
| + | server_args = -r -S -R -s db0sda-12 -r ax0 db0sda-7 | ||
| + | } | ||
| + | </file> | ||
| + | In this example //db0sda-12// is the defined master callsign in your RPC card and //ax0// is the AX.25 kernel-interface you created with //kissattach// and //db0sda-7// is the AX.25 connect path incl. the destination callsign (most probably only your RPC callsign). | ||
