1、将raspberry连接上路由器，通过以下命令查找路由器网段连接的设备
wiwa@tech:~$ sudo nmap -sP 192.168.31.0-254 Starting Nmap 7.01 ( https://nmap.org ) at 2016-11-22 20:48 CST Nmap scan report for XiaoQiang (192.168.31.1) Host is up (0.0046s latency). MAC Address: 28:6C:07:32:01:60 (Unknown) Nmap scan report for 192.168.31.16 Host is up (0.063s latency). MAC Address: B8:27:EB:E4:A2:BC (Raspberry Pi Foundation) Nmap scan report for 192.168.31.125 Host is up (-0.089s latency). MAC Address: B8:27:EB:B1:F7:E9 (Raspberry Pi Foundation) Nmap scan report for 192.168.31.240 Host is up. Nmap done: 255 IP addresses (4 hosts up) scanned in 2.30 seconds
2、通过SSH登录Raspberry Pi （密码：raspberry）：
wiwa@tech:~$ ssh pi@192.168.31.16 pi@192.168.31.16's password: The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright. Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY,to the extent permitted by applicable law. Last login: Tue Nov 22 12:01:37 2016 from 192.168.31.240 pi@raspberrypi:~ $
3、在Raspberry Pi端安装VNC server：
pi@raspberrypi:~ $ sudo apt-get install tightvncserver
4、开启Raspberry Pi VNC server端界面（首次开启需要设定密码）：
pi@raspberrypi:~ $ sudo vncserver :2 -geometry 800x600 -depth 24
5、在ubuntu端安装VNC viewer 客户端：
wiwa@tech:~$ sudo apt-get install xtightvncviewer
6、在ubuntu段登录查看Raspberry Pi的界面(输入Raspberry Pi的VNC服务器已设定的密码）:
wiwa@tech:~$ xtightvncviewer 192.168.31.125:2 Connected to RFB server,using protocol version 3.8 Enabling TightVNC protocol extensions Performing standard VNC authentication Password: Authentication successful Desktop name "pi's X desktop (raspberrypi:2)" VNC server default format: 32 bits per pixel.
