    Building and setting up netatalk 3.1.2 on Debian

1. Build

Install dependencies

sudo apt-get install automake libtool build-essential pkg-config checkinstall git-core avahi-daemon libavahi-client-dev libssl-dev libdb5.1-dev db-util db5.1-util libgcrypt11 libgcrypt11-dev libcrack2-dev libpam0g-dev libdbus-1-dev libdbus-glib-1-dev libglib2.0-dev libwrap0-dev systemtap-sdt-dev libacl1-dev libldap2-dev

Download and unpack netatalk 3.1.2

wget http://downloads.sourceforge.net/project/netatalk/netatalk/3.1.2/netatalk-3.1.2.tar.bz2
tar xvf netatalk-3.1.2.tar.bz2

Configure and make

cd netatalk-3.1.2
./configure --with-init-style=debian --with-zeroconf --with-cracklib --with-pam-confdir=/etc/pam.d --with-dbus-sysconf-dir=/etc/dbus-1/system.d

After successfull configuration the configure summary should look like this

Install

Use the option --fstrans=no to prevent failing of mkdir -p commands during the install.
sudo checkinstall --fstrans=no

2. Setup

Install HFS packages

I am using a USB HDD, which was formatted on my Mac as a HFS+ (journaled) volume. In order to mount and use this drive we have to install the necessary HFS packages:
sudo apt-get install hfsplus hfsutils hfsprogs

Mount the drive

Create the mount destination folder
sudo mkdir /mnt/Backup

Get the drive's UUID
sudo blkid

Add the drive to /etc/fstab
UUID=<UUID from blkid>    /mnt/Backup    hfsplus    force,defaults    0 0

Mount it
sudo mount /mnt/Backup

Set appropriate permissions
sudo chown backup:backup /mnt/Backup
sudo chmod 2775 /mnt/Backup

Netatalk configuration file

The configuration file is found under /usr/local/etc/afp.conf. Make sure to create the folders specified in the path of each volume.
