Hi there, i am using slack for a few months now, and i am very satisfied with it.

i have a question though.

is there someone who has experience with encrypted filesystems. I would like to implement that for my /home dir, but i am not sure what negative effects will come with it.

Will it heavily decrease performance? how to backup those data? do you have to patch the kernel? and is it perhaps already implemented in the 2.6 kernels? A link would be nice, (or better, share you experience with encrypted filesystems)

because i have google, found some info.. but nothing that could answer all my questions.

Hallo

I use loop-AES (http://loop-aes.sourceforge.net/) and made good experience with it,

There is a very good README-file, just follow the instructions, it works

it means you have to patch your 2.4 kernel (not sure about 2.6), what is no problem just follow the loop-AES.README

loop-AES doesn't decrease your performance very much

To backup those data you could use (if your encrypted partition is hda4)

cat /dev/hda4 > /tmp/backup_hda4

and burn this file to a cdrom you can open it with any other system with loop-AES installed

If you are just one person using your computer it's no problem to encrypt your whole /home
then you get the password-question on boot-up.
Because I share my computer, i just encrypted my data and mail-configuration an mount this encrypted partitition after login.

Hope that helps

sounds pretty good. i'll try that option. Any more that have suggestion?
