Configure Xmanager and VNC in linux

Article Title: Configure Xmanager and VNC in linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Today, we configured X manager and vnc on oracle linux. This is the first time we configured vnc. The vnc configuration is much simpler than X manager. Here we record it:

---- X manager Configuration:

1. modify the configuration file/etc/X11/TPD. conf of the target instance, and set the enable option in [xdmcp] to true.

[xdmcp] # Distributions: Ship with this off. It is never a safe thing to leave # out on the net. Setting up /etc/hosts.allow and /etc/hosts.deny to only # allow local access is another alternative but not the safest. # Firewalling port 177 is the safest if you wish to have xdmcp on. # Read the manual for more notes on the security of XDMCP. Enable=true

After you enter the path by using vi to edit the configuration file, enter the/xdmcp search string xdmcp "n" to search for the next sentence, so that you can quickly locate the xdmcp item.

2. Modify the/etc/X11/xdm-config file and comment out DisplayManager. requestPort: 0.

! SECURITY: do not listen for XDMCP or Chooser requests ! Comment out this line if you want to manage X terminals with xdm !DisplayManager.requestPort: 0

3. Modify the/etc/X11/xdm/Xaccess file # * # any host can get a login window to remove the first part of this line #

# right hand sides can match. # * #any host can get a login window # # To hardwire a specific terminal to a specific host, you can

4. If a firewall exists, open port 177.

OK! Use X manager after configuration.

---- VNC Configuration

1. Check whether the rpm package is installed

[oracle@niuge ~]$ rpm -qa|grep vnc vnc-server-4.0-11.el4 vnc-4.0-11.el4

As long as the first vnc-Server-4.0-11.El is enough. This is the server running program. If not, install

2. Run vncserver after installation

[test@niuge ~]$ vncserver You will require a password to access your desktops. Password: Verify: xauth: creating new authority file /home/test/.Xauthority New 'niuge:3 (test)' desktop is niuge:3 Creating default startup script /home/test/.vnc/xstartup Starting applications specified in /home/test/.vnc/xstartup Log file is /home/test/.vnc/niuge:3.log

You will be prompted to enter the logon password, and you will be prompted to remember this ": 3" is used when you log on to the vnc client. I have already enabled two machines, so this is: 3

3. Install the vnc client on the windows Server and run the client. The input method is shown in.

500) this. width = 500; "border = 0>

Click OK and prompt to enter the password you just set. Click to enter

500) this. width = 500; "border = 0>

OK! Do you think the command line method is uncomfortable? Don't worry. You can change the configuration to windows mode.

4. The following prompt is displayed when vncserver is Enabled:

Creating default startup script /home/test/.vnc/xstartup Starting applications specified in /home/test/.vnc/xstartup Log file is /home/test/.vnc/niuge:3.log

Let's take a look at the xstartup content:

#!/bin/sh # Uncomment the following two lines for normal desktop: # unset SESSION_MANAGER # exec /etc/X11/xinit/xinitrc [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & twm &

OK! It is easy to know how to normally enter the desktop.

# Uncomment the following two lines for normal desktop:  unset SESSION_MANAGER  exec /etc/X11/xinit/xinitrc

Save the modification and exit.

Stop vncserver first:

[test@niuge ~]$ vncserver -kill :3 Killing Xvnc process ID 30475 [test@niuge ~]$

Restart vncserver

[test@niuge ~]$ vncserver New 'niuge:3 (test)' desktop is niuge:3 Starting applications specified in /home/test/.vnc/xstartup Log file is /home/test/.vnc/niuge:3.log

OK! Repeat the preceding steps to log on to vnc again.

500) this. width = 500; "border = 0>

A familiar image is displayed.
