Cheat sheet: Use Ubuntu 14.04 as a Mac OS X Time Capsule

By stfb , In Cloud, Computers, Linux

Step 1: Install Netatalk


apt-get install netatalk libc6-dev avahi-daemon libnss-mdns

1 2	apt-get install netatalk libc6-dev avahi-daemon libnss-mdns

Step 2: Configure /etc/nsswitch.conf locate the line that reads:


hosts: files mdns4_minimal [NOTFOUND=return] dns

1 2	hosts: files mdns4_minimal [NOTFOUND=return] dns

Add “mdns” at the end. You should have that:


hosts: files mdns4_minimal [NOTFOUND=return] dns mdns

1 2	hosts: files mdns4_minimal [NOTFOUND=return] dns mdns

Step 3: edit /etc/netatalk/AppleVolumes.default Check that you have:


:DEFAULT: options:upriv,usedots

1 2	:DEFAULT: options:upriv,usedots

Add a line in the shares like this:


<directory path where to store time machine files> "Time Machine" options:tm allow:<usertoallow>

1 2	<directory path where to store time machine files> "Time Machine" options:tm allow:<usertoallow>

For me it looks like this for user “stfb”


/mnt/USBDrive/AppleTimeMachine "Time Machine" options:tm allow:stfb

1 2	/mnt/USBDrive/AppleTimeMachine "Time Machine" options:tm allow:stfb

Step 4: add time machine dir + user


mkdir <directory path where to store time machine files>
chown -R <usertoallow>: <directory path where to store time machine files>
adduser<usertoallow> (follow prompt)
