Sorte sua! Acabei de ter o mesmo problema e escrevi um script que facilitará a montagem de Pastas ecryptfs com o FNEK.
sudo su -
Em seguida, abra nano / vim / seu editor de preferência e crie um arquivo ecryptfs-fnek-helper.sh com o seguinte conteúdo:
#!/bin/bash
# Thanks to https://bugs.launchpad.net/ubuntu/+source/ecryptfs-utils/+bug/455709
#
echo "Where is the /home with the .ecryptfs mounted? (default=/mnt/home)"
read home_ecryptfs
if [ -z "$home_ecryptfs" ]; then
home_ecryptfs=/mnt/home
fi
home_ecryptfs=$home_ecryptfs/.ecryptfs
echo "Whose encrypted home would you like to mount?"
read user
if [ -z "$user" ]; then
echo "You have to enter a user!"
exit;
fi
echo "What is the user's password?"
read -s password
if [ -z "$password" ]; then
echo "You have to enter a password!"
exit;
fi
echo "Where would you like to mount it? (Default: /mnt/[username])"
read target
if [ -z "$target" ]; then
target=/mnt/$user
fi
target=$target/
mkdir -p $target
wrapped=$home_ecryptfs/$user/.ecryptfs/wrapped-passphrase
sig=$home_ecryptfs/$user/.ecryptfs/Private.sig
private=$home_ecryptfs/$user/.Private/
echo I will be mounting $private into $target.
echo "Clearing the keyring."
keyctl clear @u
keyctl list @u
echo "Unwrapping passphrase and inserting it into key:"
printf "%s" $password | ecryptfs-insert-wrapped-passphrase-into-keyring $wrapped -
keyctl list @u
echo -e "\e[0;92mPassphrase:"
echo -e '\e[1;92m''printf "%s" $password | ecryptfs-unwrap-passphrase $wrapped - ''\e[0m'
echo -e "\e[0;96mFilename Encryption Key (FNEK) Signature:"
echo -e '\e[1;96m''tail -n1 $sig''\e[0m'
echo -e "Mounting now! Be sure to enable FNEK!"
mount.ecryptfs $private $target -o ecryptfs_cipher=aes,ecryptfs_key_bytes=16,key=passphrase
Isto irá desembrulhar sua senha e adicioná-la ao chaveiro. Ele também exibirá o passhprase e a assinatura correta do FNEK, para que você possa copiá-los / colá-los quando solicitado pelo mount.ecryptfs.
Torne o arquivo executável e execute-o enquanto ainda está em su:
chmod +x ecryptfs-fnek-helper.sh
./ecryptfs-fnek-helper.sh
