🦑Encrypt a disk with cryptsetup

1. prepare the empty disk (sdc)

2. parted sdc
# parted /dev/sdc
> mktable
> mkpart

3. format drive as luks
# cryptsetup luksFormat /dev/sdc1

4. open luks

(where NAME is a mapped device name,
which will be seen at /dev/mapper/${NAME}
here we assume NAME=luks
)
# ls /dev/mapper/
** luks

5. format volume inside luks
# mkfs.ext4 /dev/mapper/luks
OR
# mkfs.ext4 /dev/dm-0

6. mount this ext4 filesystem
# mount /dev/dm-0 /MOUNT_POINT

7. umount filesystem
# umount /MOUNT_POINT

8. close luks
# cryptsetup luksClose /dev/dm-0



encrypt a disk image with luks
------------------------------

0. create my symlink
# ln -s /sbin/cryptsetup /sbin/luks

1. prepare a blank image file, by using dd or truncate
# truncate -s 1G luks.img

2. setup the image file as loop device
# losetup -f luks.img

3. Format this (virtual) device with luks header
# luks luksFormat /dev/loop0
P.S. input uppercase 'YES', then input your password for key slot 0

4. Open device
# luks open /dev/loop0 luks0
# lsblk

loop0     7:0    0     1G  0 loop  
└─luks0 253:0    0  1022M  0 crypt

🦑👥 Add, remove and grant sudo rights to Arch Linux users:

1) How to add, remove and grant sudo rights to users on Arch Linux
Make sure you have installed the sudo package by running the following commands as root:

# pacman -Syu
# pacman -S sudo

2) The first command will sync the repositories and update your Arch Linux system to the latest version available.
The second command will install sudo if not already installed.

🦑Then create a new user and add sudo rights to it.

1) / Create a sudo user on Arch Linux.
Run the following command to create a new user, for example undercode:

# useradd --create-home undercode
2) Set a password for the new user:

# passwd undercode
3) We have created a new user named undercode.

We haven't given the user sudo rights yet.

4) You can check if a user is a sudo user or not using the command:

# sudo -lU undercode
Output example:

5) User undercode is not allowed to run sudo on archlinux.
Yes, the user is not yet allowed to perform administrative tasks.

Let's go ahead and give it sudo rights.

To add a regular user to the sudoers list, simply add him to the wheel group.

6) For those of you curious, wheel is a special group on some Unix-like operating systems.

All members to this group are allowed to perform administrative tasks.

The Wheel group is similar to the sudo group on Debian based systems.

We can add users to the sudoers list in two ways.

7) 4The first way is to use the usermod command.

1.1. Add users to the sudoers list using the usermod command on Arch Linux
To add a user to the sudoers list on Arch Linux, run:

# usermod -aG wheel undercode
or

# usermod --append --groups wheel undercode

The above command will add a user named undercode to the "wheel" group.

As mentioned, members of the wheel group can perform administrative tasks using the sudo command.

Then edit the / etc / sudoers file with the command:

# visudo
Find and uncomment the following line (just remove the # at the beginning of the line):

%wheel ALL=(ALL) ALL
Press ESC and type: wq to save the file and exit.

You can also add the user to the sudo group:

# usermod -aG sudo undercode
Edit the / etc / sudoers file:
# visudo
Uncomment the following line:

%sudo ALL=(ALL) ALL
Save the file and exit.

We have added the user undercode to the sudoers list.

Now go to section “1.3. Let's check if the user has sudo access on Arch Linux ”and check if the user has sudo rights.
