In this activity you will resolve an issue that prevents the creation of an encrypted filesystem using eCryptfs.
You are working as a Systems Administrator and have been tasked with creating an encrypted filesystem using eCryptFS.
However, when you attempt to mount the filesystem you receive the following error:
…unknown filesystem type ‘ecryptfs’.
Resolve this error and mount the filesystem.
Successfully complete this lab by achieving the following learning objectives:
- Identify the Issue and Resolve It
Is the kernel module installed? Check with this:
lsmod | grep ecryptfs
If not, load it:
- Create the Cipher Directory and Mount Point
Create the cipher directory to hold encrypted data:
Create the mount point to access unencrypted data:
- Add Your Passphrase to the Kernel Keyring
ecryptfs-add-passphrase export KSIG=
- Mount the Encrypted Filesystem
Substitute the key signature from the
echo $KSIG sudo mount -i -t ecryptfs secret-enc/ secret/ -o ecryptfs_sig=$KSIG,ecryptfs_fnek_sig=$KSIG,ecryptfs_cipher=aes,ecryptfs_key_bytes=32,ecryptfs_unlink_sigs
