Linux settings Xhost Method Step __linux

. When setting up Xhost related programs, System prompts

Xhost access control disabled, clients can connect to any host

The first step: using Root to log Linux, start VNC service;
Step two: Based on the VNC port, set export Display=localhost:1 (1 means VNC started on the first TTY)
Step Three: Execute Xhost + and prompt "Access control disabled, clients can connect to any host" is correct.

Start

If you use a graphical interface connection between Linux operating systems, you will also use VNC from your system, and then configure VNC.

1 Check whether to install

Rpm-q | grep VNC

If you do not have a system disk to install

Rpm-ivh Vnc-server-...... rpm

2 Specify port Start service

[Root@hp4u ~]# Vncserver:1

New ' hp4u:1 (root) ' Desktop is hp4u:1

Starting applications specified In/root/.vnc/xstartup
Log file Is/root/.vnc/hp4u:1.log

This example is not the first time that you will be prompted to enter your login password the first time it is executed.

Description

The port that VNC gives to the browser is 5800+n, and the port to Vncviewer is 5900+n,n is the display number set.

For example, to start the VNC service with VNCSERVER:1, the specified port number should be 5901 when using the Vncviewer connection, and the browser port number 5801.

3 Modify Login Configuration

This step requires configuration only for the first time you use VNC.

[Root@hp4u ~]# Cd/root/.vnc # This directory is automatically generated after the first run of VNC.

[root@hp4u. vnc]# ll
