axports
AXPORTS(5) Linux Programmer's Manual AXPORTS(5)
NAME
/etc/ax25/axports - AX.25 port configuration file.
DESCRIPTION
axports is an ASCII file that contains information about each of the physical AX.25 ports that are to be used. When dealing with an AX.25
utility such as call, it takes an argument that is the port name. This port name is a reference to the line within axports, which has that
name as its first argument. The information on each line contains enough information to bind the command to a particular physical AX.25
interface, this binding is done by matching the callsign on the line in axports with the callsign of the port set by kissattach.
The lines within axports must either be a comment line, which starts with a # in the first column, or a port description in the following
format, each field being delimited by white space:
name callsign speed paclen window description
The field descriptions are:
name is the unique identifier of the port. This is the name given as the port argument of many of the AX.25 support pro-
grams. This is not in any way related to actual device identities, just unique
callsign the callsign of the physical interface to bind to.
speed this is the speed of interface, a value of zero means that no speed will be set by kissattach(8).
paclen is the default maximum packet size for this interface.
window the default window size for this interface.
description a free format description of this interface, this field extends to the end of the line. This field may contain spaces.
