VNC via Browser



Using a Web browser to Connect to VNC Server
To run an application that features a graphical user interface (GUI) on a System i™, you must use either a VNCviewer or a
Web browser to connect to the Virtual Network Computing (VNC) server. You must run the VNCviewer or Web browser on
a graphics-capable platform, such as a personal computer.
Note: The following steps require you to know your display number and VNC password. Starting the Virtual Network
Computing (VNC) server determines the value for the display number. Creating a VNC password file sets the VNC password.
Using a VNCviewer to access the VNC server
Using a Web browser to access the VNC server
To use a Web browser to connect to the VNC server, complete the following steps:
Start the browser and access the following URL:
systemname is the name or IP address of the system that is running the VNC server
nn is the 2-digit representation of the VNC server display number
For example, when the system name is system_one and the display number is 2, the URL is:
Successfully accessing the URL displays a prompt for the VNC server password. At the password prompt, type the
VNC password to gain access to the VNC server display.
Some Notes:
Using the browser client is really convenient, but it does rely on Java, and some browsers⁄configurations will have problems with Java.
Note that you should NOT include “http:” in the URL.
Another viewer is vinagre, which for instance is bundled with Ubuntu. Use the same command-line format as vncviewer above.
Configure your internet firewall to pass traffic coming in on ports 5800, 5900, and 5901 on to your computer.
For connecting to a vnc server over the internet, you need to know it’s public ip address.
This can be done through an IP-reporting website, such as What is My IP Address
