This file contains a very short introduction to the IPX implementation
on Linux. Feel free to forward comments (especially suggested additions)
to greg@caldera.com.
--------------------------------------8<--------------------------------------
Since this mail address isn't valid anymore (2002-03-10), I took care of this
package myself and enhanced this to compile under recent kernel versions and
systems. Feel free to write me: poc@pocnet.net.
--------------------------------------8<--------------------------------------
The following are important definitions in understanding the descriptions
in this README file.
IPX Interface - This is the item to which IPX sockets are bound.
An IPX interface corresponds to an IPX Network Number which corresponds
to a physical device and frame type. A sample IPX Interface would be:
Network Number: 0x00ABCDEF
Device: Eth0
Frame Type: 802.2.
The particular interface is selected during binding by using the
Network Number (see sample code below).
Primary Interface - The interface that is selected by default when
binding a socket. This is selected when binding by using
a network number of 0 (see sample code below).
Internal Network - This is a special kind of IPX interface that does
not have a physical device or frame type. It is used to provide
a route-independent address for service providers. Internal network
numbers are optional; however, when one is present it is also the
Primary Interface.
This tar file contains the following IPX utilities:
ipx_interface.c
This program is used to create an IPX interface.
ipx_internal_net.c
This program is used to create an IPX Internal Network number.
ipx_route.c
This program creates an IPX route.
ipx_configure.c
This program is used to read/write two configuration parameters:
AUTO INTERFACE CREATE - IPX should/shouldn't automatically create
an IPX interface when it discovers one that has not been
registered via ipx_interface above.
AUTO PRIMARY SELECT - IPX should/shouldn't automatically select
a primary interface when it one an interface exists and
none are designated as the primary. Manual designation
is performed via ipx_interface.
By default, these are both turned off.
The following are sample IPX programs (found in directory Samples):
ipxrcv.c and ipxsend.c
ipxsend will send a single packet to an instance of ipxrcv running on the
same machine. It uses getsockname(2) to determine the address to which to
send the packet.
rip.c
rip passively monitors the rip traffic on the attached IPX network.
sap.c
sap passively monitors the sap traffic on the attached IPX network.
There are three files in /proc/net that relate to IPX.
ipx_interface contains the list of IPX interfaces.
ipx_route contains the list of IPX routes.
ipx contains the list of IPX sockets in use.

ipx_configure \- query/configure IPX behavior
.SH SYNOPSIS
.B ipx_configure
[\-\-help]
[\-\-auto_interface=[on|off]]
[\-\-auto_primary=[on|off]]
.SH DESCRIPTION
.B ipx_configure
queries or configures IPX behavior with respect to automatic IPX
interface detection. IPX can be configured to automatically create
interfaces as they are detected. It can also be configured to
automatically select a primary interface when none is explicitly
selected. By default, it is configured to
.B NOT
have this behavior.
Without arguments,
.B ipx_configure
returns the current configuration state. The behavior with
arguments is described in the section
.B OPTIONS.
.SS OPTIONS
.TP
.I "\-\-auto_interface=[on|off]"
This argument either turns on or off the behavior of automatically creating
interfaces.
.TP
.I "\-\-auto_primary=[on|off]"
This argument either turns on or off the behavior of automatically selecting
a primary interface.
.TP
.I "\-\-help"
Print out information about utility.

.SH NAME
ipx_interface \- add, delete, or display an IPX interface
.SH SYNOPSIS
.B ipx_interface
add [-p] device frame_type [network number]
.LP
.B ipx_interface

.LP
.B ipx_interface

.LP
.B ipx_interface

.B ipx_interface

.SH DESCRIPTION
.B ipx_interface
adds, deletes, or displays IPX interfaces depending on the option selected.
.P
An IPX interface is the item to which IPX sockets are bound.
An IPX interface corresponds to an IPX Network Number which corresponds
to a physical device and frame type. A sample IPX Interface would be:
.LP
Network Number: 0x00ABCDEF
.LP
Device: Eth0
.LP
Frame Type: 802.2.
.P
There is a special IPX interface per host known as the
.B PRIMARY
or default interface.
.SS OPTIONS
.TP
.I add
This option is used to create an IPX interface. If the
.B -p
flag is used, the interface is made
.B
PRIMARY.
The network number can be optionally assigned. If it is not assigned, it
is set to 0 which indicates it should be detected from the traffic on the
network.
.TP
.I del
This option is used to delete an IPX interface.
.TP
.I delall
This option is used to delete all IPX interfaces.
.TP
.I check
This option is used to display the device, frame type, and network number
of an IPX interface.
.TP
.I help
This option displays information about the utility.
.SH FILES

.TH IPX_INTERNAL_NET 8 "IPX Utilities" "Caldera, Inc."
.SH NAME
ipx_internal_net \- add or delete the IPX internal network
.SH SYNOPSIS
.B ipx_internal_net
add network_number node_number
.LP
.B ipx_internal_net
del
.SH DESCRIPTION
.B ipx_internal_net
adds or deletes the IPX internal network.
An IPX internal network is a special kind of IPX interface that does
not have a physical device or frame type. It is used to provide
a route-independent address for service providers. Internal networks
are optional; however, when one is present it is also the
Primary Interface. There can only be one internal network per host.
.SS OPTIONS
.TP
.I add
This option is used to create the IPX internal network.
.TP
.I del
This option is used to delete the IPX internal network.
.SH FILES
.I /proc/net/ipx_interface /proc/net/ipx_route
.SH BUGS
This functionality really belongs in
.B
ifconfig(8).
