.TH AXPARMS 8 "25 July 1997" Linux "Linux System Managers Manual"
.SH NAME
axparms \- Configure AX.25 interfaces.
.SH SYNOPSIS
.B axparms --assoc|--forward|--route|--setcall|--version ...
.SH DESCRIPTION
.LP
The
.B 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
.B axassociate
and
.B 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.
.SH "--assoc Argument"
.LP
The format of this option is:
.LP
.nf
.B axparms --assoc <callsign> <username>
.br
.B axparms --assoc <callsign> delete
.br
.B axparms --assoc policy [default|deny]
.br
.B axparms --assoc show
.fi
.LP
This option mainpulates the kernel uid/callsign mapping table, allowing
callsigns to be associated and dis-associated with a user. The
.B policy
option permits the superuser to have all other uid's either default to the
actual port name, or to block traffic.
.LP
At power up the table is blank and the policy is 'default', which is thus
backward compatible.
.SH "--forward Argument"
.LP
Allows the use of many receivers with one transmitter, known as packet
forwarding in many systems. The format of this command is:
.LP
.nf
.B axparms --forward <portfrom> <portto>
.br
.B axparms --forward <portfrom> delete
.fi
.LP
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.
.SH "--route Argument"
.LP
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.
.LP
The formats of this option are:
.LP
.nf
.B axparms --route add <port> <callsign> [<digis>] [--ipmode V|D]
.br
.B axparms --route del <port> <callsign>
.fi
.B axparms --route list
.fi
.LP
Routes added via this command will not be removed from the internal routing
table when they are \(lqold\(rq as normal entries are. The
.B --ipmode
option sets mode vc or mode datagram for this destination.
.LP
If the <callsign> argument is set to \(lqdefault\(rq 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.
.SH "--setcall Argument"
.LP
The format of this option is:
.LP
.B axparms --setcall <interface> <callsign>
.LP
This changes the callsign associated at the given physical ax25 interface.
.LP
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..
.LP
The change is permanent as long as the interface exists, or another \(lqaxparms
--setcall\(rq is issued.
.LP
The interface has to exist already in order to use this option; it
may be in state UP or DOWN.
.SH "--version Argument"
.LP
This option displays the version of the AX.25 utilities that
.B axparms
belongs to.
.SH FILES
