       axparms - Configure AX.25 interfaces.


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


       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.
