使用 xrdp 隧道连接到现有的 X 服务器

Question

我正在使用现有工具，该工具需要与 Ubuntu 服务器建立 RDP 连接。

应用程序运行s在xvfb显示服务器（使用命令xvfb-运行）在服务器上的特定 DISPLAY 上。

我已经安装了 xrdp 以打开与此 Xserver 的连接，但是每次我启动新连接时，xrdp-sesman（这是 xrdp 工具的会话管理器）在不同的显示器上打开一个新的 Xvnc 服务器。

我的目标是将 xrdp 连接隧道连接到我的应用程序所在的特定 DISPLAY，有人知道这是否可行吗？

xvfb中的v表示您正在使用虚拟显示器。

您可能想查看类似 x11vnc 的内容。

x11vnc allows one to view remotely and interact with real X displays (i.e. a display corresponding to a physical monitor, keyboard, and mouse) with any VNC viewer. In this way it plays the role for Unix/X11 that WinVNC plays for Windows.

AskUbuntu 有这样的设置指南（引用如下）

You'll need xrdp together with x11vnc if you want remote access to your Unity desktop.

First, install xrdp and x11vnc: apt-get install xrdp x11vnc (or whatever your distribution equivalent is)

Then edit /etc/xrdp/xrdp.ini and make sure it contains at least the following:

 [globals]
 bitmap_cache=yes 
 bitmap_compression=yes 
 port=3389
 crypt_level=high 
 channel_code=1 
 max_bpp=24


 [xrdp1]
 name=Remote Desktop
 lib=libvnc.so
 username=ask
 password=ask
 ip=127.0.0.1
 port=5900

Restart xrdp for the changes to take effect:

/etc/init.d/xrdp restart

Now open up a terminal window (Ctrl+Alt+T) and set up a VNC password (you don't want to leave wide open access to your desktop from the internet):

x11vnc -usepw

You'll be prompted to set up a password, that will be used for RDP authentication.

The last step is to start x11vnc. There are tons of options that you can use, but here is an example to get you started (run this in the same terminal window you just opened):

x11vnc -rfbauth ~/.vnc/passwd -display WAIT:0 -reopen -nevershared
-forever -wirecopyrect always -scrollcopyrect always -norepeat -1 -xkb -capslock -skip_keycodes 187,188 -bg -o ~/x11vnc.log &

The & at the end will leave x11vnc running the background, so you can close the terminal window and leave it running.

You'll need to add this command to your startup scripts if you want x11vnc to run automatically after a reboot.
