Hi, all

I solved my problem easily.

my solution is rpm -ivh option.

But, I had another problem...

First, I made private folder and input below command in sdb(rd-pq).

mount -t ecryptfs ~/private ~/private

it is not working with error.

this is error message ...

Unable to get the version number of the kernel
module. Please make sure that you have the eCryptfs
kernel module loaded, you have sysfs mounted, and
the sysfs mount point is in /etc/mtab. This is
necessary so that the mount helper knows which
kernel options are supported.

Make sure that your system is set up to auto-load
your filesystem kernel module on mount.

Enabling passphrase-mode only for now.

there is something wrong with your kernel keyring. Did you build key
retention support into your kernel?

how to solve this error...please help me..
