10
12 The axparms command is designed to be a multi-function command that
13 allows miscellaneous commands to be issued to the Linux AX.25 protocol
14 layer. The different modes of the command are chosen by the first
15 argument. Subsequent arguments depend upon this argument and so no gen‐
16 eralised command format can be given.
17
19 The format of this option is:
20
21 axparms --assoc <callsign> <username|uid>
22 axparms --assoc <callsign> delete
23 axparms --assoc policy [default|deny]
24 axparms --assoc show
25
26 This option mainpulates the kernel uid/callsign mapping table, allowing
27 callsigns to be associated and dis-associated with a user. The policy
28 option permits the superuser to have all other uid's either default to
29 the actual port name, or to block traffic.
30
31 At power up the table is blank and the policy is 'default', which is
32 thus backward compatible.
33
35 Allows the use of many receivers with one transmitter, known as packet
36 forwarding in many systems. The format of this command is:
37
38 axparms --forward <portfrom> <portto>
39 axparms --forward <portfrom> delete
40
41 Any packets to be transmitted on port portfrom will be transmitted on
42 port portto. This will stay in force until the second form of the com‐
43 mand is issued which will remove the association.
44
46 This option allows the internal AX.25 routing table to be manipulated.
47 This table is available for reading in /proc/net/ax25_route, and will
48 be built up dynamically by stations heard. However it is possible to
49 add, delete and list entries via this option.
50
51 The formats of this option are:
52
53 axparms --route add <port> <callsign> [<digis>] [--ipmode V|D]
54 axparms --route del <port> <callsign>
55 axparms --route list
56
57 Routes added via this command will not be removed from the internal
58 routing table when they are “old” as normal entries are. The --ipmode
59 option sets mode vc or mode datagram for this destination.
60
61 If the <callsign> argument is set to “default” then this will set the
62 default route for all outgoing AX.25 connections which will be used
63 when there is no specific route to the required destination.
64
66 The format of this option is:
67
68 axparms --setcall <interface> <callsign>
69
70 This changes the callsign associated at the given physical ax25 inter‐
71 face.
72
73 Cave: The interface name is not the symbolic port name from axports,
74 but the real interface name (from ifconfig(8)): ax0, ax1, .., sp0, ..,
75 bpq0, ... etc..
76
77 The change is permanent as long as the interface exists, or another
78 “axparms --setcall” is issued.
79
80 The interface has to exist already in order to use this option; it may
81 be in state UP or DOWN.
82
84 This option displays the version of the AX.25 utilities that axparms
85 belongs to.
