vnc remote control software

VNC (Virtual Network Console) is the abbreviation of virtual network console. It is an excellent remote control tool software. The vnc remote control software has powerful remote control capabilities, is efficient and practical. The software is developed based on the Linux system. It is easy to use and can be traveled on the Windows platform. VNC allows you to access and control your desktop applications with performance comparable to any remote control software in Windows and MAC.

VNC remote control software function introduction

    Support multiple operating systems

VNC Server and VNCVviewer support multiple operating systems, such as windows, Linux, MacOS and Unix series (Unix, Solaris, etc.), so VNC server and VNC viewer can be installed in different operating systems for control;

      Intelligent control

The advantage of RealVNC is that if the VNC viewer is not installed on the host computer of the operating system, the controlled terminal can also be controlled through a general network browser (such as IE, etc.) (requires the support of Java virtual machine).

How to use vnc remote control software

(1) Start VNC Server on the server side.

(2) The VNC client connects to the VNC Server through a browser or VNC Viewer.

(3) VNC Server sends a dialog window to the client, requiring input of the connection password and the accessed VNC Server display device.

(4) After the client enters the connection password, the VNC Server verifies whether the client has access rights.

(5) If the client passes the verification of VNC Server, the client will ask VNC Server to display the desktop environment.

(6) VNC Server requires X Server to transfer screen display control to VNC Server through X Protocol.

(7) The VNC Server will be sent to the client from the desktop environment of the X Server using the VNC communication protocol in the future, and the client will be allowed to control the desktop environment and input devices of the VNC Server.

Frequently asked questions about vnc remote control software

What are the commands of vnc remote control software?

vncserver

This service program must be running on the main (or remote) computer. You can only use this service as a user (no root user required).

vncviewer

A local application used to remotely access the computer running vncserver and display its environment. You need to know the IP address of the remote computer and the password set by vncserver.

vncpasswd

Password setting tool for vncserver. The vncserver service program will not be able to run without setting a password (good practice). If you do not set it, vncserver will prompt you to enter a password when you run it. So, generally I wouldn't run this command alone to set a password.

vncconnect

Tell vncserver to connect to the IP and port number of a remote computer running vncviewer. This way I avoid giving other people a password to access.

wxya

A vnc "master" program generally does not need to be run directly. (vncserver and vncviewer are actually Xvnc scripts)

To find all available options, run:

Xvnc --help

For security reasons, it is generally not recommended to run the vncserver program directly with the superuser account. If you need a super user environment, please log in as a normal user and then use the su command to log in to the super user account.

How to log in to the controlled terminal through the graphical interface?

Edit ~/.VNC/xstartup

         #!/bin/sh

        # Uncomment the following two lines for normal desktop:

        # unset SESSION_MANAGER

​​​# exec /etc/X11/xinit/xinitrc

[ -x /etc/VNC/xstartup ] && exec /etc/VNC/xstartup

[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources

xsetroot -solid gray

VNCconfig -iconic &

​​​ #xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &

​ ​ gnome-session & It is recommended to choose this. . . For everything else, add # in front of it.

Startkde &

        twm &

​​ gnome-session is to start the Gnome graphical interface; startkde is to start the KDE graphical interface; twm is to start the text interface. Choose one of the three.

Frequently asked questions about vnc remote control software

Problem description: When trying to connect to a remote host using a VNC client, the connection fails or times out.

Possible reasons: network instability, VNC server/client configuration errors, firewall or security group settings blocking VNC port access.

Solution:

Check whether the network connection is stable and eliminate problems caused by network reasons.

Confirm whether the VNC server and client configurations are correct, including IP address, port number, password, etc.

Check your firewall or security group settings to make sure the VNC port (usually 5900+) is not blocked.
