9 Ax25d.conf controls the functioning of ax25d. Its purpose is to spec‐
10 ify on which ports to listen on, which applications are available, and
11 to whom they are available to. The configuration file is common to both
12 AX.25, NET/ROM and Rose and their is similarity between the two parts
13 of the file.
14 The general layout for an entry for a given port is as follows:
16 interface control
18 callsign entry 1
19 .
20 .
21 callsign entry n
22 The interface control line determines which port and callsigns apply to
24 the following callsign entry lines, until the next interface control is
25 read. There are four different variants of the interface control line:
26 1. [AX.25 Port Name]
28 2. [Callsign VIA AX.25 Port Name]
29 3. <NET/ROM Port Name>
30 4. {Callsign VIA Rose Port Name}
31 Version 1 allows the following callsign entry lines to listen on the
33 AX.25 port specified by the AX.25 port name using the default callsign
34 of that AX.25 port.
35 Version 2 allows the following callsign entry lines to listen on the
37 AX.25 port specified by the AX.25 port name using the callsign speci‐
38 fied instead of the default callsign of that AX.25 port. Specifying a
39 * for the AX.25 port name allows the following callsign entries to be
40 valid for all the operating AX.25 ports using the callsign specified.
41 VIA can be abbreviated to just V. If the callsign has an asterisk
42 appended to it then the system will be listening on the port with the
43 callsign, but as a pseudo-digipeater instead of being the normal desti‐
44 nation callsign.
45 Version 3 allows the following callsign entry lines to listen on the
47 NET/ROM port specified by the NET/ROM port name using the default call‐
48 sign of that NET/ROM port.
49 Version 4 allows the following callsign entry lines to listen on the
51 Rose port using the specified Rose port name using the callsign speci‐
52 fied as the service access point (SAP). A * may be specified for a
53 callsign to allow matching to any incoming Call Requests with any SAP.
54 The callsign entry lines have a similar layout for both AX.25, NET/ROM
56 and Rose, the layout is:
57 peer window t1 t2 t3 idle n2 mode uid exec args...
59 All values must be entered for all entries even when they are not used
61 (ie window for NET/ROM, just enter a * instead), The meanings of each
62 of the fields is given below. All timings apart from the idle value are
63 given in seconds, the idle values is given in minutes.
64 peer This specifies the callsign of the remote end of the
66 connection that should have the following parameters
67 and executable set up for them. The syntax of the peer
68 argument is explained below.
69 window This sets the the value of the window size, if a value
71 of * is entered in this field then the default value
72 for the port is taken from the “parameters” entry (see
73 below) or lacking such an entry, the kernel default
74 value is used. This entry is used by AX.25 but not by
75 NET/ROM or Rose.
76 t1 This sets the the value of the T1
