C. LINUX SETUP
See the following sites which the below information has been compiled from:
http://thehamptons.com/anders/netatalk/
http://www.linuxworld.com/linuxworld/lw-1999-04/lw-04-uptime.html
What�s installed:
* AppleVolumes.default -- List of directories to share plus optional names
for those directories. The default name is the last element of the path.
* AppleVolumes.system -- This controls the mapping of file extensions to
types that Mac OS understands. You shouldn't have to do anything to this
file except possibly add a new file extension to it.
* afpd.conf -- This is the conf file for the AppleTalk filesystem daemon.
* atalkd.conf -- Controls the interfaces to which Netatalk binds and any
network numbers or zones you want to assign to them. If blank (the default)
Netatalk will try to discover the interfaces itself and bind to them. If
there is more than one interface, it will automatically route between them.
* papd.conf -- papd is the daemon that makes Linux print queues available
via AppleTalk. If the conf file is empty, it will make all entries in
/etc/printcap available.
* .AppleDouble -- this directory stores the resource fork of macintosh files
on linux, which stores the file type, and the application which created it,
what application to launch/associated with it. For files that don't have a
resorce fork (e.g. native files generated by linux), the resource fork is
generated by netatalk by guessing on the extension (*.txt for simple text
documents, *.jpg *.gif, etc for photoshop documents, etc), but for files
that did come with a resource fork, deleting it would means breaking the
files for its intended purpose. It is particularly true for programs - the
resource fork of a macintosh program stores the icon, the pull menu's, etc.
Deleting/corrupting the resource fork would certain make your program
non-functional. So only delete the content of AppleDouble if you know the
resource fork is unimportant (i.e. linux native files). For Mac native
files, it is a very dangerous advice.
1. Distribution installed? If your Linux distribution already has netatalk
installed, you can skip to section ??? Otherwise, start with the next
paragraph.
You will need to add AppleTalk support to your kernel. Some Linux
distributions ship with AppleTalk support. If this isn�t the case for you,
or if you�ve since built a kernel without AppleTalk support, you�ll need to
con�gure and compile a new kernel. To enable kernel support for AppleTalk,
select AppleTalk DDP as a module when con�guring. Adding AppleTalk support
as a module is better than building it straight into your kernel, as it will
allow you to reset AppleTalk completely without disturbing other networking
activity by simply removing and reinserting the module. The module is, not
surprisingly, named appletalk.o.
����# rmmod appletalk
����# insmod appletalk
To �nd out whether your kernel has AppleTalk support as a module, see if
/lib/modules//misc/appletalk.o exists. You can check your kernel version
with the uname -r command. To check if AppleTalk support has been compiled
directly into the kernel, see if the �le /proc/net/appletalk/ exists or
check the boot messages (using dmesg) for a line like �NET4: AppleTalk 0.18
for Linux NET4.0�. If the sources used for the current kernel are available,
you can also check /usr/src/linux/.con�g to see if CONFIG_ATALK is set to y.
If you need help rolling your own custom kernel, consult the kernel HOWTO.
2. Decompress and untar the source code with the following commands:
elmer:~/src> gzip netatalk-1.4b2+asun2.0a18.2.tar.gz
elmer:~/src> tar -xvf netatalk-1.4b2+asun2.0a18.2.tar
or if you downloaded the rpm version:
eyore:~/src> rpm -i netatalk-1.4b2+asun2.1.0-5.i386.rpm
3. Edit the Make�le in the root of the source tree:
Set the destination directory:
DESTDIR=/usr/local/atalk
which is the default is probably OK for most installations. Comment out PAM
support if you don�t have it. If you don�t have PAM, (Plugable
Authentication Modules) you should comment out the line that reads
PAMDIR=/usr. Basically RedHat uses PAM and Slackware doesn�t. PAM makes it
so you can �plug� user authentication modules (ways of checking usernames
and passwords) into your system. Typical authentication modules would
include shadow password support, NIS support, etc.
4. Edit the etc/afpd/Make�le If you need shadow password support. (PAM
takes care of shadow password checking, so if you have PAM and a shadow
password system, you can skip this step.) Most major Linux distributions
such as RedHat use shadow password suites. If you don�t know if you have
shadow passwords, look at your password �le. If you have an �x� where the
encrypted password should be, you have shadow passwords and you need to
de�ne shadow passwords in your Make�le. ( Sample line from a shadow password
�le: root:x:0:0::/root:/bin/tcsh )
Add -DSHADOWPW to the etc/afpd/Make�le like so:
CFLAGS= ${DEFS} ${AFSDEFS} ${KRBDEFS} ${DESDEFS} ${OPTOPTS} ${INCPATH} \
${PAMDEFS} -DAPPLCNAME -DCRLF -DSHADOWPW # -DDOWNCASE
If you are running libc.so.5, comment out -lrpcsvc in sys/linux/Make�le. If
you�re using PAM, add -DUSE_PAM to this Make�le.
5. Install a DES library if you don�t already have one and are planning on
useing encrypted passwords. (If not, comment the DES line out of the Make�le
and skip this step.)
Get a copy of libdes from
[ftp://ftp.psy.uq.oz.au/pub/Crypto/DES/libdes.tar.gz].
Untar it somewhere and do a make.
To optionally install libdes on your system (which isn�t a half bad idea)
type make install.
You will need the �le des.h which should be there if the make was
successfull.
Copy des.h to your netatalk include directory: cp des.h
/path/netatalk/include/.
6. Install TCP Wrappers if it�s not already installed.
To compile, netatalk needs tcpd.h so if you don�t already have it, download
the TCP Wrappers package from [ftp://ftp.cert.org/pub/tools/tcp_wrappers/].
Type cp tcpd.h /path/netatalk/include/ to copy tcpd.h to your netatalk
source include directory. You probably have tcpd on your system. In the rare
case that you don�t, you�ll want to compile it now by typing make
REAL_DAEMON_DIR=/usr/sbin linux and instal it. Look at the included README
�le for installation instructions.
7. Compile netatalk
The all important step: in your netatalk source directory, type make. Make
sure everything compiles up without an error. You may see some warnings
which are safe to ignore, but if you see the compiler exit with some sort of
error, try and see if you can �gure out why it is dying. Remember, the
compiler is going to look in your include directory for tcpd.h and des.h so
make sure they are there. If you are really having trouble with the compile,
try the tips page. If you are really having trouble, you could download a
pre-compiled version of netatalk from the download page.
[http://thehamptons.com/anders/netatalk/download.html]
8. Install netatalk
Type make install in the source directory and netatalk will be installed
where you stated in the Make�le. (default is /usr/local/atalk)
9. Edit /etc/services
Add the following lines to your /etc/services �le:
rtmp 1/ddp # Routing Table Maintenance Protocol
nbp 2/ddp # Name Binding Protocol
echo 4/ddp # AppleTalk Echo Protocol
zip 6/ddp # Zone Information Protocol
afpovertcp 548/tcp # AFP over TCP
afpovertcp 548/udp
10. Copy atalkd.conf
Type cp conf/atalkd.conf /usr/local/atalk/etc/. The simplest con�g �le for
atalkd (like the one you just copied) is one with no commands in it.
atalkd is the �classic Appletalk� kernel interface. It will serve as the
link between the kernel appletalk module and the rest of the classic
Appletalk functions of netatalk. It will even take care of Appletalk routing
between multiple network cards.
11. Copy afpd.conf �le
Type cp con�g/afpd.conf /usr/local/atalk/etc. This �le sets Classic
Appletalk and Appleshare IP server options. Leaving it alone is the easiest
thing to do, however the default does not enable AppleshareIP and there are
quite a few con�gurable options in this �le so there is a section speci�c to
it at:
[http://thehamptons.com/anders/netatalk/afpd.conf.html]
12. Copy and edit AppleVolumes.*
Type cp conf/AppleVolumes.default /usr/local/atalk/etc and cp
conf/AppleVolumes.system /usr/local/atalk/etc. The AppleVolumes.default and
AppleVolumes.system �les are listings of volume to path mappings and type /
creator mappings. AppleVolumes.default will be parsed when a real user logs
in. (ie: not the guest account) The settings in AppleVolumes.default can be
overridden with an AppleVolumes or .AppleVolumes �le in the users� home
directory. AppleVolumes.system will be processed for all users. Adding the
lines:
#
# volumes
~ Home
/music �Some Tunes�
#
# type / creator mappings
.txt TEXT MSWD
will cause two volumes to show up, one called Home which is the user�s home
directory and one called Some Tunes that is the directory /music. The rest
of the �le is a listing of �dot extensions� to type / creator mappings. A
Mac �le has two parts, a data fork and a resource fork. Unix �les are only
one long list of bits. Therefore, if you have the �le test.txt created in
Unix, looking at it on the Mac will reveal an �Unknown Document� icon unless
there is an entry in the type / creator section of the AppleVolumes �les.
The last line in the above example will make a �le ending in .txt show up as
a Microsoft Word (MSWD) text (TEXT) document and will launch Word when
double-clicked. (You actually register programs with Apple to have a an
of�cial creator mapping assigned.) The default list of type / creator
mappings in the AppleVolumes.system �le is probably adequate unless you are
planning on making many �les in Unix and using them on Macs. One possible
reason to use a large type / creator map is if you plan to export the same
directory to Windows clients via Samba and you want Mac users to be able to
double click PC �les to open them.
Compile Appletalk in your kernel
There are two kinds of Appletalk servers you can run, and both can run at
the same time. Classic Appletalk needs to run atalkd and afpd while
Appletalk over TCP/IP only requires that afpd be running. Atalkd requires
that Appletalk and TCP/IP support be compiled into your kernel while
Appletalk IP only requires TCP/IP support. Many mainstream Linux
distributions contain a kernel with Appletalk already compiled in and
everyone probably has TCP/IP. You can check to see if your kernel supports
Appletalk by typing:
dmesg | grep Apple
If you see anything pop up such as Appletalk 0.17 for Linux NET3.035 you
have Classic Appletalk compiled into your kernel. If not you could check to
see if you have Appletalk inserted into the kernel via a module by typeing:
lsmod and seeing if Appletalk shows up there. If neither of these statements
show Appletalk, then you have to compile Appletalk into the kernel and
reboot, or compile Appletalk as a module and insmod appletalk.o. If you need
help compiling Appletalk into the kernel, take a look at the Kernel-HOWTO.
(usually included in major distributions in the docs directory /usr/doc)
Start the server
Now comes the moment of truth. Try to test a startup of the netatalk server
by running one of the rc.atalk scripts in the root of the netatalk source
tree. Type
./rc.atalk.sysv
start and give it a few seconds. This will start up a Classic Appletalk
�leserver and Appletalk IP if you have any TCP options set in the afpd.conf
�le. Atalkd will take the longest to start as it checks out the network
before registering itself. Alternatively you could just run an Appletalk
over TCP/IP server by having a TCP server con�gured in the afpd.conf �le and
launching afpd by hand:
/usr/local/atalk/etc/afpd -F /usr/local/atalk/etc/afpd.conf
If everything seems to have started up without complaning, go to a Mac and
open the chooser. (under the Apple menu on the left hand side) Click on
AppleShare and see if your netatalk server shows up. (for AppleshareIP you
have to click the AppleshareIP button and type your machine IP or name in.
With some luck you will be presented with a password prompt. You can only
log into the server with a non root account that has a valid shell and a
password of 8 or less characters. Guest access is also permitted unless
denied in afpd.conf. If you can�t log in as anyone but guest you probably
don�t have shadow password support compiled into your netatalk executables.
If you are able to login, you will get a list of volumes which you can
select and mount.
Use one of the startup scripts included with netatalk to launch your server
when your system boots. There are a variety of ways that a machine will boot
up. Some have an rc.local �le where you can specify the path to an rc.atalk
script while others use a symbolic link with a nameing scheme to determine
the order in which startup scripts will run. Take a look at /etc/rc.d/ or
/etc/init.d/ for startup scripts. If you want to serve more than 5
connections, you must supply a max connections variable to afpd. The -c �ag
will set this.
afpd -c 25
Jonathan Benson passed along a SysV style startup script which takes
con�guration information from a con�g �le which supports starting things in
the background. Anyone who wants to use it should untar it when logged in as
root in their root (ie: /) directory then edit the �le /etc/atalk/con�g. You
can download it below:
[http://thehamptons.com/anders/netatalk/mirror/atalk-sysv.tar.gz]
Other options are available in atalkd and afpd as well as a suite of tools
for diagnosing and administrating a netatalk setup. Try man atalkd and man
afpd for con�guration options and look at the Utilities page at:
[http://thehamptons.com/anders/netatalk/utils.html]
D. MACINTOSH SETUP
1. Plug the Ethernet Cable in
When you are connecting ONLY two nodes (either two computers or a computer
and a printer) you will need a cross-over cable. With more, you will need
ethernet cables per each node (item) to the ethernet hum/concentrator.
2. Go to the Apple Menu and select Appletalk under Controls Panels (Mac OS
8.5. Earlier version will vary)
At the Connect via, select Ethernet. If you have a PPP connection with your
ISP, you will have to make two TCP/IP configurations and save each of them.
One configuration is for PPP using your modem with the Connect via set at
PPP and the Configure set to �Using PPP server.� The other configuration is
for the network with the IP setting as 192.168.66.? and the subnet mask as
255.255.255.0 with the name of the server as 192.168.66.?. Save and name
each setting (such at ISP and Home Network). Once these settings are
configured and saved, all it takes is selecting the Configurations under the
File menu and selecting the TCP/IP connection you want and select �Make
Active� for you choice.
2.1 Mac OS 7.5.5 (future input).
3. Go to Chooser and Select Appleshare.
If everything is set up correctly, under the File server you should see the
name of your computer. Click on the file server and then click OK. You
will see a dialog box which states �connect to the file server �your servers
name� and you will be able to start from the �Registered Guest� which is
your login and password. Click OK and you will have brought up all of the
folders which you have access permissions. If you have more than one
folder, you can select each one one at a time and each will be displayed one
at a time and you will have to go back and start from the beginning of this
paragraph. Or select them all by shift-clicking. Finally, click on
�Connect.�
3.1 Additional info about earlier versions.
4. Linux networked folder icon is displayed.
You�re off and running.
5. Telnetting into your Linux Box
Get a program called BetterTelnet Fat 2.0b4 or NCSA Telnet 2.7b4 (fat). At
the Open connection under the file menu, put the IP address where it
belongs, such as 192.168.66.? (your Mac IP address).?????

Simple. He probably wants to build an mp3 player for his car, and this sort

As for boards, I know that PC-100 is notorious for making these kinds of
boards. I know that right now they also have a board that you can use
either a Sockey 370 or Slot 1 chip in that has all of these features. I
would go with a low end Socket 370 chip and go to town for this sort of

Sort of. But in reality, if you want to re-write the network stack, you
should already have enough knowledge of C, Linux, TCP, and Networking that
the only questions you should have to ask in the Linux newsgroups would be
individual little things.
You've got a big job ahead of you if you actually think you're going to be
able to re-write the entire network stack and keep most existing functionality.

should I add to it?)
Second, inetd does not exist in /etc/rc.d/init.d for me! There is some

I could see this being the problem. Getting around it
another issue.
: May be xon/xoff characters get messed up with actual data?
Software compression is turned off on the modem, local software,
and remote software.
: May be crtscts is not working as it should for this particular modem?
: Some modems use DTR instead of RTS. (see pppd man page, cdtrcts option)
Tried cdtrcts with no luck.
THanks for the suggestions though... you've got me thinking.
