# Creating a new user on your Linux server and configuring it for administrative tasks
## 1. Create a New User
- Log in to Your Server as the root user or a user with sudo privileges.
- Add a New User:
`sudo adduser newusername`
Replace `newusername` with the desired username.
- Follow the prompts to set the user's password and provide additional information.
## 2. Grant Sudo Privileges (Optional)
If you need the new user to have administrative privileges, add the user to the sudo group:
- Add User to the Sudo Group:
`sudo usermod -aG sudo newusername`
This command adds the user to the sudo group, which grants administrative permissions.
## 3. Configure SSH Access
- Switch to the New User:
`su - newusername`
- Create SSH Directory and Authorized Keys:
`mkdir -p ~/.ssh
chmod 700 ~/.ssh
touch ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys`
- Add Your Public Key to authorized_keys:
- Open authorized_keys in an editor:
`vim ~/.ssh/authorized_keys`
- Paste your SSH public key into the file
## 4. Configure SSH Access for New User
Ensure the new user can log in via SSH:
- Edit the SSH Configuration File (/etc/ssh/sshd_config):
`sudo nano /etc/ssh/sshd_config`
- Verify or Add the Following Settings:
`PermitRootLogin no
AllowUsers newusername`
`PermitRootLogin no` disables root login via SSH.
`AllowUsers newusername` allows the new user to log in.
- Restart SSH Service:
`sudo systemctl restart ssh`
## 5. Test SSH Access
- Log Out from the Root User or current session.
- Log In as the New User:
`ssh newusername@your_server_ip`
- Verify that you can access the server with the new user.
