Reproduced from: http://www.cnblogs.com/qpanda/p/4331782.html

The current commonly used agreement has vnc/spice/rdp three kinds of, just do a simple introduction here.

Comparison of three kinds of protocols

	SPICE	Vnc	Rdp
BIOS Screen Display	Yes	Yes	No
Full color support	Yes	Yes	Yes
Change resolution	Yes	Yes	Yes
Multiple Monitors	Multi-monitor support (up to 4 images)	Only one screen	Multi-monitor support
Image transfer	Image and graphics transmission	Image transfer	Image and graphics transmission
Video playback Support	GPU Acceleration Support	No	GPU Acceleration Support
Audio transmission	Bidirectional voice can be controlled	No	Bidirectional voice can be controlled
Mouse control	The client server can control	Server-side control	Server-side control
USB Transmission	USB can be transmitted over the network	No	USB can be transmitted over the network

First, VNC

Applicable systems: Windows, Linux

Network traffic: Small, commonly used around 100k

Application scenario: mainly for Linux server management, due to no sound and USB transmission, not satisfied with the use of virtual desktop

# install
yum install tigervnc-server   

#vnc服务器启动
vncserver   

#查看连接
vncserver  -list  

#修改访问密码
vncpasswd   

#关闭vncserver
vncserver-kill:n

Configuration file Modification

#配置文件修改 
vim/etc/sysconfig/vncservers  

# vncservers= "2:myusername"   Sessionnumber, username
# vncserverargs[2]= "-geometry 800x600-nolisten tcp-localhost"

vncservers="1:root" # Display port and username
vncserverargs[1]="-geometry 800x600-nolisten tcp-nohttpd "

Second, SPICE

Applicable system: Linux

Network traffic: Large, normal use 10-20m

Scenario: for virtual desktops for color, audio, and USB, mainly for virtual desktop applications of virtual machines

Use: After installation, need to configure in the virtual machine, refer to my blog about the virtual machine.

Third, RDP

There are currently two types of RDP on Windows, Remote,remotefx

Applicable systems: Windows, Linux

Network traffic: Small, normal use 100-200k around

Scenario: Ideal for virtual desktops due to better color, audio, USB, and Local disk mappings

Windows use: You can use the system after installation.
