I wuold like to use a key for non interactivity boot of machine but i wuold like to protect data from reading without that key. And for that reason i try to do that, but the problem is "HOW TO" do that... Your idea of use an external factor (MAC Address etc...) is very interesting but is it possibile? > Dick Duke --------------------------------------------------------------------- - http://www.saout.de/misc/dm-crypt/ To unsubscribe, e-mail: dm-crypt-unsubscribe@xxxxxxxx For additional commands, e-mail: dm-crypt-help@xxxxxxxx
