How to configure /etc/fstab to auto mount encrypted partition?

Recently installed openSUSE 12.1 dual booting with Debian.

Layout listed below:

Code:

Debian    ext3    /root  sda1    

Debian    ext3    /home  sda2  (encrypted with luks)

          swap    swap    sda3

openSUSE  ext4    /      sda5    

openSUSE  ext4    /home  sda6  (encrypted with luks)

When in Debian, I am able to manually mount openSUSE /home (sda6) and get the files that I needed from there.

Wanted to know how to configure Debian's /etc/fstab so that I can automatically mount sda6 (after entering password) during boot.

Thanks

I had asked a similar question. I didn't get a response either. So I am guessing the answer is no.

LOL,
this is a good reply,
thanks for the heads up.

How do you mount Debian in openSUSE? Maybe you can wright a script for your autostart when logging in or maybe rclocal. Documentation seams to be skimpy on the and the only thing I could find was an FAQ that said to mount with a loop0 when doing a backup.

Try this site. http://code.google.com/p/cryptsetup/

Description: configures encrypted block devices

 Cryptsetup provides a command-line interface for configuring encrypted devices. This is done using the Linux kernel device mapper target dm-crypt. This

 version of cryptsetup has integrated support for LUKS. 

 

 cryptsetup is backwards compatible with the on-disk format of cryptoloop, but also supports more secure formats. This package includes support for

 automatically configuring encrypted devices at boot time via the config file /etc/crypttab. Additional features are cryptoroot support through

 initramfs-tools and several supported ways to read a passphrase or key.

That's all I could find and you may have all ready seen this stuff.

Try this Howto from Arch Linux. https://wiki.archlinux.org/index.php...tion_with_LUKS Looks like they go into it in depth.

Found the answer, logged here for future users who's looking for the same answer:

1. Add this line to /etc/crypttab:

my_encrypted_partition /dev/sda6 none luks,timeout=30

2. Set the home partition to this in /etc/fstab:

/dev/mapper/my_encrypted_partition /home ext4 nodev,nosuid,relatime 0 2

You'll be asked the passphrase for my_encrypted_partition during boot up. That's it.

Merry Christmas.

I saw this...... and set this up in CENTOS 7...

It does not prompt you for a password, it just drop you to emergency maintenance mode upon boot up.

But this worked for me:
udisksctl unlock -b /dev/sda2
udisksctl mount -b /dev/mapper/vg_tesla-lv_home

Obtained from the 3rd answer to this ask Ubuntu post..
(1st post so can't post a web link..... but its:

Automatic mounting on bootup didn't work for me...
