How to configure the port of Tigervnc in Debian system

This article guides you how to configure the port of the Tigervnc server on a Debian system.

1. Install Tigervnc server

First, make sure that the Tigervnc server is installed. If not installed, execute the following command:

 sudo apt update
sudo apt install tigervnc-standalone-server tigervnc-common

2. Configure the Tigervnc server

The Tigervnc configuration file is usually located in ~/.vnc/xstartup . You can edit this file to set ports and other parameters.

Edit the xstartup file:

Open or create a ~/.vnc/xstartup file using a text editor (such as nano):

 nano ~/.vnc/xstartup

Adjust file contents according to your desktop environment. The following example applies to the GNOME desktop environment:

 #!/bin/sh

unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
gnome-session &

Other desktop environments (such as KDE, XFCE) need to be modified accordingly.

3. Set up custom ports

Tigervnc uses port 5900 n by default (n is the display number). You can customize the port by launching the script. Create or edit the startup script ~/.vncserver :

 nano ~/.vncserver

Add the following and replace 5902 with the port number of your choice:

 #!/bin/sh

export VNCPORT=5902
vncserver:1

Grant script execution permissions:

 chmod x ~/.vncserver

4. Start the Tigervnc server

Start the server with the following command:

 ~/.vncserver

Or use a custom port:

 ~/.vncserver:1

5. Connect to VNC server

Use the VNC client to connect to the specified port (e.g. localhost:5902 ).

6. Firewall configuration

Allows the firewall to pass through a custom port. For example, use ufw:

 sudo ufw allows 5902/tcp

Summary: Follow the above steps to successfully configure the Tigervnc port in the Debian system. Please make sure the configuration file is correct and the corresponding port is opened in the firewall.
