Introduction
|
||
|
|
------------
|
||
|
|
|
||
|
|
AppleTalk-IP (IPDDP) is the method computers connected to AppleTalk
|
||
|
|
networks can use to communicate via IP. AppleTalk-IP is simply IP datagrams
|
||
|
|
inside AppleTalk packets.
|
||
|
|
|
||
|
|
Through this driver you can either allow your Linux box to communicate
|
||
|
|
IP over an AppleTalk network or you can provide IP gatewaying functions
|
||
|
|
for your AppleTalk users.
|
||
|
|
|
||
|
|
You can currently encapsulate or decapsulate AppleTalk-IP on LocalTalk,
|
||
|
|
EtherTalk and PPPTalk. The only limit on the protocol is that of what
|
||
|
|
kernel AppleTalk layer and drivers are available.
|
||
|
|
|
||
|
|
Each mode requires its own user space software.
|
||
|
|
|
||
|
|
Compiling AppleTalk-IP Decapsulation/Encapsulation
|
||
|
|
=================================================
|
||
|
|
|
||
|
|
AppleTalk-IP decapsulation needs to be compiled into your kernel. You
|
||
|
|
will need to turn on AppleTalk-IP driver support. Then you will need to
|
||
|
|
select ONE of the two options; IP to AppleTalk-IP encapsulation support or
|
||
|
|
AppleTalk-IP to IP decapsulation support. If you compile the driver
|
||
|
|
statically you will only be able to use the driver for the function you have
|
||
|
|
enabled in the kernel. If you compile the driver as a module you can
|
||
|
|
select what mode you want it to run in via a module loading param.
|
||
|
|
ipddp_mode=1 for AppleTalk-IP encapsulation and ipddp_mode=2 for
|
||
|
|
AppleTalk-IP to IP decapsulation.
|
||
|
|
|
||
|
|
Basic instructions for user space tools
|
||
|
|
=======================================
|
||
|
|
|
||
|
|
To enable AppleTalk-IP decapsulation/encapsulation you will need the
|
||
|
|
proper tools. You can get the tools for decapsulation from
|
||
|
|
http://spacs1.spacs.k12.wi.us/~jschlst/index.html and for encapsulation
|
||
|
|
from http://www.maths.unm.edu/~bradford/ltpc.html
|
||
|
|
|
||
|
|
I will briefly describe the operation of the tools, but you will
|
||
|
|
need to consult the supporting documentation for each set of tools.
|
||
|
|
|
||
|
|
Decapsulation - You will need to download a software package called
|
||
|
|
MacGate. In this distribution there will be a tool called MacRoute
|
||
|
|
which enables you to add routes to the kernel for your Macs by hand.
|
||
|
|
Also the tool MacRegGateWay is included to register the
|
||
|
|
proper IP Gateway and IP addresses for your machine. Included in this
|
||
|
|
distribution is a patch to netatalk-1.4b2+asun2.0a17.2 (available from
|
||
|
|
ftp.u.washington.edu/pub/user-supported/asun/) this patch is optional
|
||
|
|
but it allows automatic adding and deleting of routes for Macs. (Handy
|
||
|
|
for locations with large Mac installations)
|
||
|
|
|
||
|
|
Encapsulation - You will need to download a software daemon called ipddpd.
|
||
|
|
This software expects there to be an AppleTalk-IP gateway on the network.
|
||
|
|
You will also need to add the proper routes to route your Linux box's IP
|
||
|
|
traffic out the ipddp interface.
|
||
|
|
|
||
|
|
Common Uses of ipddp.c
|
||
|
|
----------------------
|
||
|
|
Of course AppleTalk-IP decapsulation and encapsulation, but specifically
|
||
|
|
decapsulation is being used most for connecting LocalTalk networks to
|
||
|
|
IP networks. Although it has been used on EtherTalk networks to allow
|
||
|
|
Macs that are only able to tunnel IP over EtherTalk.
|
||
|
|
|
||
|
|
Encapsulation has been used to allow a Linux box stuck on a LocalTalk
|
||
|
|
network to use IP. It should work equally well if you are stuck on an
|
||
|
|
EtherTalk only network.
