Time Capsule on PandoraBox

Posted on Edited on Disqus: Word count in article: 4.4k Reading time ≈ 4 mins.

My “OpenWRT” is “PandoraBox”, and the router is “Mi mini”.
These are slight differences from the official wiki.

Then, SSH to your PandoraBox

opkg update
opkg install shadow-useradd shadow-groupadd
cd /usr/lib
ln -s libgcrypt.so.20 libgcrypt.so.11

In your browser

System -> Software -> Actions -> Download and install package

  • netatalk
  • avahi-daemon
  • kmod-usb-storage
  • kmod-fs-hfsplus
  • block-mount

Do not attempt “opkg install” as described in the wiki, otherwise you will get an error message.

 * opkg_configure: kmod-fs-hfsplus.postinst returned 2.

Format & Mount

Insert the BackUp hard drive into Mi mini

Use blkid to find your sda, this is mine

1
/dev/sda3: UUID="dab3d8b8-a87f-3bfb-9fed-f42934d5bcd6" LABEL="BackUp" TYPE="hfsplus" PARTLABEL="Basic data partition" PARTUUID="27db40be-8ebe-11e6-9e2e-60f81da8c0cd"

Format it as ext4 (Mi mini fails to mount hfsplus, so I try ext4 as an alternative)

1
mkfs.ext4 /dev/sda3

groupadd timemachine
useradd -M -G timemachine tmuser
passwd tmuser
# input the passwd

mkdir /mnt/TimeMachine
chown root:timemachine /mnt/TimeMachine
touch /mnt/TimeMachine/USB_DISK_NOT_PRESENT
chmod 555 /mnt/TimeMachine -R
chmod 444 /mnt/TimeMachine/USB_DISK_NOT_PRESENT

In the browser

System -> Mount Points -> Mount Points -> Add

Select the UUID you get by blkid mount to /mnt/TimeMachine, remember the size xxx MB, save

You may see /dev/sda3 /mnt/TimeMachine in Mounted file systems

Then in your SSH

1
chown -R tmuser:timemachine /mnt/TimeMachine

Netatalk

1
vim /etc/netatalk/afpd.conf

Change all the text to:

1
"TimeMachine" -uampath /usr/lib/uams -uamlist uams_dhx2.so -nodebug -nouservol -icon -nosavepassword -mimicmodel RackMac
1
vim /etc/netatalk/AppleVolumes.default

Replace all the text with the following (fill in the previous xxx you obtained, it is in MiB)

1
/mnt/TimeMachine TimeMachine volsizelimit:xxx allow:@timemachine rwlist:@timemachine cnidscheme:dbd options:searchdb,usedots,invisibledots,tm

In your browser

System -> Startup Enable

  • avahi-daemon

Restart the router

On your Mac, go to System Preferences -> Time Machine -> Select Disk -> Available Disks -> on "Time Capsule", you should see TimeMachine
