Now we’re going to link the config stuff to /etc
.
Nota: este manual es algo antiguo, y ya en muchos sistemas, tenemos integrado el paquete netatalk o bien puede instalarse con el gestor de paquetes, ya sea apt-get o yum

This is a guide on how to mimic an OS X file server using Linux and the open source implementation of AFP, Netatalk. These instructions are for Ubuntu Server 10.04, but should translate pretty easily to other distros.
I have a Linux NAS, but all my other computers are Macs. NFS is simple, but buggy. There are all sorts of problems if you disconnect from the network without unmounting first. Also, I ran into issues where Finder would just lockup upon opening an NFS mounted directory.
Time to make the switch to AFP.
Installing netatalk
OS X doesn’t like sending clear text passwords, so you have to install libgcrypt-dev so netatalk builds the uams_dhx2.so module
sudo aptitude install build-essential libdb-dev libgcrypt-dev
wget http://prdownloads.sourceforge.net/netatalk/netatalk-2.1.4.tar.bz2?download -O netatalk-2.1.4.tar.bz2
tar xjf netatalk-2.1.4.tar.bz2
cd netatalk-2.1.4
./configure --prefix=/usr/local/netatalk-2.1.4
make && sudo make install
Because we installed by source, we gotta do some symlinking and creating of config files, etc. First off, I like to make a link in /usr/local
.
sudo ln -s /usr/local/netatalk-2.1.4 /usr/local/netatalk |
sudo ln -s /usr/local/netatalk/etc/netatalk /etc/netatalk |
Now install this initd script as /etc/init.d/netatalk
and edit SBIN_PATH
and BIN_PATH
according to where you installed netatalk.
BIN_PATH=/usr/local/netatalk/bin SBIN_PATH=/usr/local/netatalk/sbin |
Configuring netatalk
Pretty easy. You just gotta configure two things: afpd and what volumes you want to share.
My /etc/netatalk/afpd.conf
is just one line.
- -tcp -noddp -uamlist uams_dhx2.so,uams_guest.so -nosavepassword |
It says “my default server uses tcp, not ddp and allows users to authentica via dhx2 or as a guest without saving their password.” At least, that’s what I think it says. The afpd.conf
file is well document and it also has a man page.
My /etc/netatalk/AppleVolumes.default
is similarly simple.
:DEFAULT: options:upriv,usedots /mnt/quantum "Quantum" allowed_hosts:192.168.0.0/16 |
The :DEFAULT:
section applies to all volumes. upriv
means use Unix privileges andusedots
means hide files that start with a dot. I’m only exporting one volume named Quantum and the arguments are pretty self explanatory. Again, the AppleVolumes.default
is well documented and there a man page for it as well.
Now you can start it up.
sudo /etc/init.d/netatalk start |
And connect to it via Finder -> Go -> Connect to Server…
For the “Server Address:” I fill out afp://hostname/Quantum
where “hostname” is my Linux machine’s hostname and “Quantum” is the name of my volume.
The authentication credentials are your Linux username and password. Your Linux user will need permissions on the exported volume (obviously).
Troubleshooting
Can’t connect? See what’s going on by changing your afpd.conf
to be something like.
- -tcp -noddp -uamlist uams_dhx2.so,uams_guest.so -nosavepassword -setuplog "default log_debug /tmp/afpd.log"
Now you can tail -f /tmp/afpd.log
to see what’s going on when you try to connect. Note, there are other log levels than “log_debug” if you need more info. See the man page.
Configuring Avahi
So by now you’ve noticed that your Linux AFP server doesn’t show up in the Finder’s sidebar like other real Macs do. Not a problem, we can fix that by installing and configuring Avahi to advertise it.
sudo aptitude install avahi-daemon libnss-mdns |
Now edit /etc/nsswitch.conf
and make sure the “hosts” line has “mdns” in it.
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 mdns |
Now create a new file /etc/avahi/services/afpd.service
and fill it out.
