How to manage remotely via Tigervnc

This article guides you how to configure TigerVNC on Debian system to implement remote desktop management.

1. Install TigerVNC server

1. System update: First update your Debian system package:

    sudo apt update
   sudo apt upgrade

2. Install TigerVNC: Install TigerVNC server:

    sudo apt install tigervnc-standalone-server

3. Create a VNC desktop environment: Create the necessary directories and configuration files:

    sudo mkdir -p ~/.vnc
   sudo nano ~/.vnc/xstartup

   Add the following content to the xstartup file (this example uses GNOME. If you need another desktop environment, please replace the corresponding command, such as XFCE uses xfce4-panel ):

    #!/bin/sh
   export XKL_XMODMAP_DISABLE1
   unset SESSION_MANAGER
   unset DBUS_SESSION_BUS_ADDRESS
   [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
   [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
   xsetroot -solid grey
   gnome-panel &
   gnome-settings-daemon &
   metacity &

4. Set VNC password: Use the vncpasswd command to set the VNC server password:

    vncpasswd

5. Start VNC server: Start VNC server, the default port is 5901 ( :1 represents the first VNC session):

    vncserver:1

6. Set up power-on self-start: Make the VNC server run automatically when the system starts:

    sudo systemctl enable vncserver@:1.service
   sudo systemctl start vncserver@:1.service

2. Connect to TigerVNC server

1. Install VNC client: Install a VNC client software (such as RealVNC, TightVNC, or TigerVNC) on your remote computer.
2. Connect to Debian: Use the VNC client to connect to the Debian system's IP address and port number (e.g. your_debian_ip_address:5901 , replacing your_debian_ip_address as your Debian system IP address).

3. Enhance safety

To improve security, we recommend that you:

• Use safer authentication methods: Consider using more advanced authentication methods to enhance security.
• Change your password regularly: Change your VNC password regularly to prevent unauthorized access.
• Firewall Configuration: Configure the firewall to allow only VNC connections from trusted IP addresses.

Through the above steps, you can safely access and manage your Debian system remotely. Please adjust the configuration according to your actual needs.
