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.
|
|
|
|
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.
