New page

For quite awhile now regular distributions of the open source Linux operating system have
included ax.25 networking support in the kernel.

Some distributions of Linux make ax.25 available in source form but require a recompile of the kernel to
activate it. [http://www.linuxdocs.org/HOWTOs/AX25-HOWTO-4.html Kernel Recompile for AX.25] External Link to one of many sites describing one way to recompile a Linux Kernel for AX.25 use.

After you have the ax.25 kernal support ready you need to define specific ax.25 interfaces.
The website [http://www.febo.com www.febo.com] covers this very well.

You should note that ax.25 network interfaces are based on the TCP/IP networking that
is built into the system. Ax.25 interfaces have IP addresses along with their interface
name and their ax.25 address. Adding an ax.25 network interface to a computer that
already has one or more TCP/IP network interfaces (DSL, ethernet, dial-up internet/PPP)
turns your computer into a multi-homed host. You most likely will want the IP
addresses on your ax.25 interfaces to be from a different subnet than the addresses
used by other network interfaces on that same computer. And you definitely don't
want to use a "real" IP address. Use something from one of the [www.wikipedia.org/wiki/Private_network private network]
non-routed IP subnets, and a subnet not already known to that computer.

***Warning***

Linux ax.25 kernel support creates network interfaces. Software on your Linux system
will use those interfaces in ways you might not expect. The common flub concerns
the MS-Windows network compatibility package Samba. Samba normally
helps itself to every network interface defined on your system. It sends out SMB network discovery
packets and merrily carries on. But you probably don't want to be sending
out SMB packets on the packet radio or APRS network. So investigate that
a little bit. If you don't need Samba then you can turn it off from the services
control panel (whatever your distribution uses). Or, in the Samba configuration
you can tell it what network interfaces to use (and not use).
