Hi,everybody,
I have some puzzles on the 'gbde' function.
I saw the gbde(4), I do not understand the 'cold' true meaning. My point
is that if the disk were stealed by somebody, he could not see anything in
the disk unless he knows the "pass-phrase". right?
In the first barrier, the manual said that "metadata" is necessary to
locate the lock-sector, I want to know how we get "metadata".
I added the option "GEOM_BDE" into my kernel conf file. I am trying....
I do as following gbde(8):
Current# gbde init /dev/da1s1f -l /etc/da1s1f.lock
gbde: illegal option -- l
Usage error: Invalid option
Usage:
gbde attach dest -l filename
gbde detach dest
gbde init dest [-i] [-f filename] -l filename
gbde setkey dest [-n key] -l filename
gbde destroy dest [-n key] -l filename
Current# touch /etc/da1s1f.lock
Current# gbde init /dev/da1s1f -f /etc/da1s1f.lock
gbde: Missing number_of_keys property
The 'da1s1f' partition exists, but I do not mount it. I first try to test
'da0s1f', but the box info:"gbde: /dev/da0s1f: Device busy".
If I want to test the 'gbde' function, could somebody give me some help?
How can I do?
Best Regards
Ouyang Kai
