Ok, first install netatalk and avahi.
sudo apt-get install netatalk avahi-daemon
Now let's create and edit our new avahi service
sudo nano /etc/avahi/services/afp.service
<?xml version="1.0" standalone='no'?> <!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> <type>_device-info._tcp</type> <port>548</port> <txt-record>model=Xserve</txt-record> </service> <service> <type>_adisk._tcp</type> <port>9</port> <txt-record>sys=waMA=MM:MM:MM:MM:MM:MM</txt-record> <txt-record>dk0=adVF=0x81,adVN=TimeMachine,adVU=UUUU</txt-record> </service> </service-group>If you are running Samba on this server as well, you might want to change the <name> field. I have changed mine to <name>timelord</name>. This will allow your timemachine/apple shares to coexist on the same server (it will look like a different server in Finder though)
MM:MM:MM:MM:MM:MM should be the MAC address of your Ubuntu server. You can quickly find it by running the following command.
ifconfig -a | grep HWaddrUUUU needs to be a unique UUID. Go to guidgen.com to generate a UUID. Now save the file, and let's move on.
Create some directories and a new user:
sudo mkdir -p /mnt/timemachine
sudo useradd -c "Time Machine User" -d /mnt/timemachine/ -s /bin/false -g 10 timemachine
sudo passwd timemachine
Set your timemachine share so it is supported:
sudo touch /mnt/timemachine/.com.apple.timemachine.supported
Set some ACLs:
sudo chown -R timemachine:users /mnt/timemachine
Next we move to setting up two files for netatalk:
sudo nano /etc/netatalk/afpd.conf
at the very bottom of the file, add:
- -tcp -nozeroconfThis tells netatalk to use tcp and not use zeroconf, if you don't use this then you will get two enties in Finder.
Configure your /etc/netatalk/AppleVolumes.default file:
# By default all users have access to their home directories. #~/ "Home Directory" /mnt/timemachine "TimeMachine" allow:timemachine options:tm # End of File
Now restart your services, and you should be done:
sudo service netatalk restart
sudo service avahi-daemon restart
