users and sudo

users wiki

View default shell

• cat /etc/passwd

set default login shell

• /etc/default/useradd

See all users on system

• sudo passwd -Sa

See users groups

• groups $USER
• id $USER

See user’s defaults

• cat /etc/passwd | grep $USER

Enable sudo without passwords (normal solution)

• sudo nvim /etc/sudoers
• uncomment wheel nopasswd

Manjaro solution
Manjaro calls @includedir /etc/sudoers.d at the end of /etc/sudoers

• echo -e "$USER ALL=(ALL:ALL) NOPASSWD: ALL\nDefaults:$USER verifypw=any\n" | sudo tee "/etc/sudoers.d/dont-prompt-$USER-for-sudo-password"

sshd

• sudo systemctl start sshd
• systemctl status sshd

find ip address

• if a
• ifconfig
• ip -o route get to 8.8.8.8 | sed -n 's/.*src \([0-9.]\+\).*/\1/p'

Increase sshd connection speed

• uncomment “UseDNS no” in sshd_config
• add “GSSAPIAuthentication no” to $HOME/.ssh/config

termux sshd
For frequented networks can set GrapheneOS wifi privacy to “use device MAC” to avoid IP address changing all the time. \
