Adding new users to the VPS

Creating using newuser script

It is preferred to use the newuser script because it already sets SSH keys to the newly created user, sets their password to expired, creates their home directory, etc.

sudo newuser USERNAME "USER_PUBLIC_KEY"

Example:

sudo newuser someone "ssh-rsa

Resetting Lost/Forgotten passwords

Super easy, just run

sudo chage -d0 "username"
sudo passwd -d "username"

Then, the next time they log in, they'll be prompted to set their password!

Creating UNIX users

Only if you know what you're doing! Otherwise use newuser script above! USERNAME here is to be switched by the new user's username.

  • Creating the account
sudo -H useradd -m USERNAME
  • Granting administrator permissions (WARNING! NEVER USE UNLESS YOU TALK TO THE OTHER ADMINS!)
sudo -H usermod -aG adm USERNAME
  • Adding a SSH Key to the new user

    • It starts with ssh-rsa and then a lot of random letters, It finishes with an identification for the key(usually an email, but can be anything)

    • If it starts with -----BEGIN RSA PRIVATE KEY----- YOU SHOULDN'T DO ANYTHING WITH IT, signal the sender that they leaked their private key and the best course of action is to generate a new one

    • Adding public key:

    sudo -Hu USERNAME nano /home/USERNAME/.ssh/authorized_keys
