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 policy
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 <serial-device> <callsign>
This changes the callsign associated with the given serial device in
KISS mode. The change is permanent until the link is downed or another
“axparms -setcall” is made.
The interface must already have been attached with kissattach to use
this option.
-version Argument
This option displays the version of the AX.25 utilities that axparms
belongs to.
