OT, I know, but this is information that all tor node operators should have.

If you use an ephemerally keyed swap you don't even have to provide a password at boot— it will use a new random key at every reboot. First edit /etc/crypttab, and add a line (or create the file): swap /dev/sda9 /dev/urandom swap,cipher=aes-lrw-plain,size=256 (replace "sda9" with the name of your swap device, "swapon -s" will tell you. It is important that you get this right.) Then edit /etc/fstab and change the swap line to /dev/mapper/swap swap swap defaults 0 0 Reboot and your swap will be encrypted (cryptsetup status swap will give you information on the volume). *********************************************************************** To unsubscribe, send an e-mail to majord...@torproject.org with unsubscribe or-talk in the body. http://archives.seul.org/or/talk/
