BEACON(8) Linux System Managers Manual BEACON(8)NAME
beacon - transmit periodic messages on an AX.25 port.
SYNOPSIS
beacon [-c <src_call>] [-d <dest_call>[digi ..]] [-l] [-m] [-s] [-t interval] [-v] port "message"
DESCRIPTION
Beacon transmits the message text on an AX.25 port every thirty minutes. The message is addressed to "IDENT" and is sent using the AX.25
callsign of the port specified on the command line. Typically the message text will contain spaces and/or other characters, therefore the
message text should be enclosed in quotes to ensure they are passed to the beacon program untranslated.
OPTIONS -c Configure the source callsign for beacons. The default is to use the interface callsign.
-d Configure the destination callsign for beacons. The default is "IDENT". Optional: Digipeaters may follow, separated with
spaces. Use -d "DEST DIGI1 DIGI2 .."
-l Enables the logging of errors to the system log, the default is off.
-m Changes the destination address to "MAIL" and sends the message text once only. This option overrides any destination call-
sign given with the -d option.
-s Sends the message text once only.
-t interval The time interval between messages, the interval is given in minutes and the default is thirty minutes.
-v Display the version.

AXPARMS(8) Linux System Managers Manual AXPARMS(8)NAME
axparms - Configure AX.25 interfaces.
SYNOPSIS
axparms --assoc|--forward|--route|--setcall|--version ...
DESCRIPTION
The axparms command is designed to be a multi-function command that allows miscellaneous commands to be issued to the Linux AX.25 protocol
layer. It includes the functionality of axassociate and axsetcall which this command superceedes. The different modes of the command are
chosen by the first argument. Sunsequent arguments depend upon this argument and so no generalised command format can be given.
--assoc Argument
The format of this option is:
axparms --assoc <callsign> <username>
axparms --assoc <callsign> delete
axparms --assoc policy [default|deny]
axparms --assoc show
This option mainpulates the kernel uid/callsign mapping table, allowing callsigns to be associated and dis-associated with a user. The pol-
icy option permits the superuser to have all other uid's either default to the actual port name, or to block traffic.
At power up the table is blank and the policy is 'default', which is thus backward compatible.
--forward Argument
Allows the use of many receivers with one transmitter, known as packet forwarding in many systems. The format of this command is:
axparms --forward <portfrom> <portto>
axparms --forward <portfrom> delete
Any packets to be transmitted on port portfrom will be transmitted on port portto. This will stay in force until the second form of the
command is issued which will remove the association.
--route Argument
This option allows the internal AX.25 routing table to be manipulated. This table is available for reading in /proc/net/ax25_route, and
will be built up dynamically by stations heard. However it is possible to add, delete and list entries via this option.
The formats of this option are:
axparms --route add <port> <callsign> [<digis>] [--ipmode V|D]
axparms --route del <port> <callsign>
axparms --route list
Routes added via this command will not be removed from the internal routing table when they are "old" as normal entries are. The --ipmode
option sets mode vc or mode datagram for this destination.
If the <callsign> argument is set to "default" then this will set the default route for all outgoing AX.25 connections which will be used
when there is no specific route to the required destination.
--setcall Argument
The format of this option is:
axparms --setcall <interface> <callsign>
This changes the callsign associated at the given physical ax25 interface.
Cave: The interface name is not the symbolic port name from axports, but the real interface name (from ifconfig(8)): ax0, ax1, .., sp0, ..,
bpq0, ... etc..
The change is permanent as long as the interface exists, or another "axparms --setcall" is issued.
The interface has to exist already in order to use this option; it may be in state UP or DOWN.
--version Argument
This option displays the version of the AX.25 utilities that axparms belongs to.
