ubuntu x11vnc 使用web 访问vnc
计算中心节点，没有远程控制不能活，就得装个VNC。
启动Ubuntu的软件中心，选择“X11VNC服务器”，进行安装。当然也可以用sudo apt-get install命令安装。
接下来创建登陆密码sudo x11vnc -storepasswd
输入和确认之后，密码被保存到了用户的密码目录下：
再设置X11VNC的密码文件：
sudo x11vnc -storepasswd in /etc/x11vnc.pass
将密码文件复制过去：
sudo cp /root/.vnc/passwd /etc/x11vnc.pass
打开/etc/init/x11vnc.conf文件，粘贴以下内容。
如果没有这个文件，就用文本工具创建一个。端口:5900，自己可以定义。
要打开web 访问VNC，并加参数： -shared -http
start on login-session-start
script
x11vnc -display :0 -auth /var/run/lightdm/root/:0 -forever
-bg -o /var/log/x11vnc.log -rfbauth /etc/x11vnc.pass -rfbport 5900 -shared -http
end script
保存后重启Ubuntu。
在别的操作系统里启动VNC Viewer，这里用的是Windows 7下安装的Real VNC。
输入对应的IP地址或主机名，点击Connect连接。 
如图，可见Ubuntu登陆界面。 
输入和确认之后，密码被保存到了用户的密码目录下：sudo x11vnc -storepasswd
将密码文件复制过去：sudo x11vnc -storepasswd in /etc/x11vnc.pass
sudo cp /root/.vnc/passwd /etc/x11vnc.pass
如果没有这个文件，就用文本工具创建一个。端口:5900，自己可以定义。
要打开web 访问VNC，并加参数： -shared -http
start on login-session-start script x11vnc -display :0 -auth /var/run/lightdm/root/:0 -forever -bg -o /var/log/x11vnc.log -rfbauth /etc/x11vnc.pass -rfbport 5900 -shared -http end script
输入对应的IP地址或主机名，点击Connect连接。
Using Web Browser to Remote Desktop Login to pcDuino
In this post, we discuss how to remote access pcDuino’s desktop using a web browser.
To achieve that, a x11vnc server needs to be installed on pcDuino. As x11vnc is built with the factory provided image, we just need to configure it.
Step 1 Configure the password to remote access
1 | $x11vnc -storepasswd |
Step 2 Start VNC Server
1 | $x11vnc -display :0 -xkb -rfbauth .vnc/passwd -auth .Xauthority -shared -http |
Now it will dump out the following information:

Step 3 Open a web browser
As shown in the log, the port for web access is 5801. We just need to access http://ipaddress:5801. In our case, the ip address is 192.168.1.133.
Enter the IP address along with the port number in the address bar of a web brower and hit enter:
If the Java plug in is not installed like in our case, it will prompt us to install. Click ‘Install plug-in..':
Click ‘Free Java Download’ to download the plug in:
Install the plug in:
After the installation is done, restart the browser and enter the IP address again:
For the permission, please select ‘Always run on this site’.
Oops. Huston. We got problem!
Don’t be panic. Find an utility named ‘Configure Java':
Navigate to the security tab, and select the security level to be medium:
Now we restart the web browser, and it will ask for the password when we enter the IP and port address of the pcDuino server:
The password is ‘ubuntu’ as we configure in the first step. The desktop of the remote pcDuino will show up in your browser:
