This might already exist somewhere, or in numerous pieces on the forum, but I thought I would write up a brief explanation of how to get your Ubuntu box sharing home folders with your Mac OS X box. I decided to use the native networking protocol AFP (over tcp) and advertise using zeroconf so I had a more seamless networking environment. I use Ubuntu as a simple server and would like to access my home directory from time to time. While I did find all of the pieces to do this between here, other forums, and a wiki, I thought it would be nice to have a simple all in one post that covered it all. Pardon me if there is already something like it. My installation of Ubuntu is Edgy running 2.6.17-10-powerpc (running on a mac mini). I would assume that you could do the very same on the x86 version as well. If someone reads this and has luck with it, please let me know. :)
First things first, in order to get AFP working, you'll need to install netatalk. Now, the problem here is that netatalk as stored in the repositories does not have the proper plugin to facilitate encrypted passwords, so on the Mac side of things it will nag you about sending passwords in the clear. We'll get by that pretty easily though by building the package ourselves. Also, you need to make sure that you have the universe repositories available for the distribution. Hop into the command line and from your home directory enter these commands:
sudo apt-get build-dep netatalk
sudo apt-get install cracklib2-dev fakeroot libssl-dev
sudo apt-get source netatalk
cd netatalk-2.0.3/
sudo DEB_BUILD_OPTIONS=ssl dpkg-buildpackage -rfakeroot
sudo dpkg -i ~/netatalk_2.0.3-4_i386.deb
Now that we have it installed, we want to make sure that dpkg does not overwrite our changes, so we run the command:
echo "netatalk hold" | sudo dpkg --set-selections
Netatalk should be installed, so we just need to share out the home directories.
nano /etc/netatalk/afpd.conf
Type this line into the file and save:
- -noddp -uamlist uams_randnum.so,uams_dhx.so
Now we need to create the file that directs netatalk to what we want shared.
nano /etc/netatalk/AppleVolumes.default
Type this into the file and save. This shares each users home directory
~
Now just restarts the daemon and all is well.
sudo /etc/init.d/netatalk restart
All of this is well and good, but what if we want to make this more seamless we need to advertise the shared directory so that we can see it in Finder. To do this, I decided to use Avahi so I could keep everything close to the way OS X does things with zeroconf. First we install the daemon:
sudo apt-get install avahi-daemon
That's really all you need to do to get things up and running, but maybe you're like me and want to be able to ping in both directions. If so, what you need to do is install a library to enable mDNS. These next few steps are optional, but useful if you plan on mounting shares on the Ubuntu side of things.
sudo apt-get install libnss-mdns
Also, we need to add mdns as a valid means for host lookup.
sudo nano /etc/nsswitch.conf
find the line with label "hosts:" (probably line 12) and add mdns to the end so that it reads:
hosts:files dns mdns
Now that we have avahi working both ways and set up correctly, we need to advertise that we are running an AFP service on our machine. To do that:
sudo nano /etc/avahi/services/afpd.service
Now just paste / type out what you see below:
<?xml version="1.0" standalone='no'?><!--*-nxml-*-->
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service-group>
<name replace-wildcards="yes">%h</name>
<service>
<type>_afpovertcp._tcp</type>
<port>548</port>
</service>
</service-group>
Save the file and then restart the avahi daemon.
sudo /etc/init.d/avahi-daemon restart
When your network catches up to you, and it might take a few minutes, you should see your newly shared out home directories in the Mac OS X finder. The last thing we need to do is load avahi at boot. To do this, just:
sudo nano /etc/default/avahi-daemon
and change
AVAHI_DAEMON_START=0 to AVAHI_DAEMON_START=1
If you run into problems setting up Avahi, you can always go to:
