Rocky 9 Linux HP All-in-One Printer Installation and Setup
Introduction
Printing and scanning with an all-in-one HP printer is possible on linux thanks to HPLIP.
This guide was tested with an HP Deskjet 2700 series.
See All Supported Printers to see if the HPLIP package supports your printer.
Download and Install HPLIP
HPLIP is third-party software by HP that contains necessary printer drivers. Install the 3 packages below for full support with a graphical user interface.
```
sudo dnf install hplip-common.x86_64 hplip-libs.x86_64 hplip-gui

Secure Remote Support on LAN with x11vnc over SSH on Rocky Linux
Subscribe to 22halomedia YouTube Channel
Read this same article on the Rocky Linux Documentation website
Introduction
x11vnc is a powerful VNC program that distinguishes itself by utilizing the existing X session instead of creating a new one. This makes it an excellent tool for providing remote support, as the user’s screen or X session can be controlled remotely.
In this guide, you will learn how to stand up an x11vnc server and how to connect to it remotely.
Setting Up the VNC server
To capture a user’s X session, x11vnc server will need to be installed on their Rocky workstation.
Disable Wayland
First, you need to disable Wayland. Open the custom.conf file using your text editor of choice:
```
sudo vim /etc/gdm/custom.conf
```
Uncomment WaylandEnable=false:
```
# GDM configuration storage

[daemon]
WaylandEnable=false

[security]

[xdmcp]

[chooser]

[debug]
# Uncomment the line below to turn on debugging
#Enable=true
```
Restart gdm service:
```
sudo systemctl restart gdm
```
Install and configure x11vnc
Enable the EPEL repository:
```
sudo dnf install epel-release
```
Install x11vnc:
```
sudo dnf install x11vnc
```
Create a password for x11vnc:
```
x11vnc -storepasswd ~/.x11vnc.pwd
```
Create a new file with your text editor of choice. This will be used to create a service to run x11vnc:
```
sudo vim /etc/systemd/system/x11vnc.service
```
Copy and paste the following text into the file, then write and quit. Replace the rfbauth path with the path to the password file you created earlier. Replace User and Group with the user you intend to provide remote support to:
```
[Unit]
Description=Start x11vnc at startup
After=display-manager.service

[Service]
Type=simple
Environment=DISPLAY=:1
Environment=XAUTHORITY=/run/user/1000/gdm/Xauthority
ExecStart=/usr/bin/x11vnc -auth /var/lib/gdm/.Xauthority -forever -loop -noxdamage -repeat -rfbauth /home/server/.x11vnc.pwd -rfbport 5900 -shared
User=server
Group=server

[Install]
WantedBy=multi-user.target
```
Enable and start the x11vnc service:
```
sudo systemctl enable --now x11vnc.service
```
Setting Up Your Client
Install the EPEL repository
Install the EPEL repository:
```
sudo dnf install epel-release
```
Install a VNC client
Install TigerVNC. We will not be using the server, but will utilize the client:
```
sudo dnf install tigervnc
```
Create the SSH Tunnel
Create an SSH tunnel to securely connect to the VNC server:
```
ssh -L 5900:localhost:5900 REMOTEIP
```
Launch the VNC Viewer
Open your VNC viewer:
```
vncviewer
```
Connect to the VNC server by entering 127.0.0.1 or localhost into TigerVNC and connect.
Enter the x11vnc password you created earlier.
Conclusion
At this point, you have successfully set up an x11vnc server and connected to it using a TigerVNC client. This solution is ideal for providing remote support, as it shares the same X session as the user, ensuring a seamless support experience.
