NAME

6       axparms - Configure AX.25 interfaces.
7

SYNOPSIS

9       axparms --assoc|--forward|--route|--setcall|--version ...
10

DESCRIPTION

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

--assoc Argument

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

--forward Argument

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

--route Argument

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

--setcall Argument

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

--version Argument

84       This option displays the version of the AX.25  utilities  that  axparms
85       belongs to.
