Can anyone tell me how to encrypt swap under SuSE 9.3? This is standard on Mac's and should be as well possible in 9.3.
On a SUSE 9.2 (default-kernel) system it was almost trivially easy to set up an encrypted swap, IIRC. You can try this for your 9.3: put an entry like /dev/hdXX swap swap sw,loop=/dev/loopNNN,encryption=AES256,pri=99 0 0 in your /etc/fstab. The "pri=..." part is optional, and you may select different algrithms for the "encryption=..." part (read the man pages for details). Replace "XX" with your designated swap device, and replace NNN with a number from 0-15 to select a loop device (0-15 loop devices seem to be standard in S92). I use loop 5 and 6, FWIW. Check with lsmod if you have the AES (or your selected encryption) module running; I believe it wasn't even necessary to modprobe the module somewhere in /etc/init.d, but I am not sure about that now. (My lsmod output shows "aes_i586 .....") Then, just run "swapoff -a" (just to be sure) and "swapon -a", and you're all set. Get back to the list or to me if it doesn't work right away; my failing memory might be missing some minor step since it's been a while ... HTH, Axel
PS: Sorry for writing in German on the first posting. Should not happen again ;-)
I hadn't even noticed: ik spreken deuts (sogar richtiges :-) ) (sorry for replying to Chris instead of the list the first time)
