X11vnc is an easy way to remotely access your Linux desktop from another Windows or Linux computer. In this post I will explain how to use X11vnc to securely access your Linux computer from Windows. X11vnc is a VNC server. A VNC server sends images of an X display to a client whenever the display changes. X11vnc is different from Xvnc because it works with X displays that are used with a real monitor. This is useful because you can connect to your normal desktop and use any applications you have left open.
X11vnc is also easier to set up than a VNC server that creates a virtual display. The first step is installing X11vnc and a SSH server on the computer that you want to be able to connect to.
This command will install both in Ubuntu or Debian. If you want to access your computer from outside your network you will need to forward port 22 to the computer running the SSH server.
Forwarding a VNC port is not needed. Also, you will need to know your global IP address so you can connect to it. A service like No-IP can help you with this. You can either download the normal stand-alone version of PuTTY or download a portable version that does not write to the Windows registry. I would recommend the portable version if you want to use it from public computers.
The last piece of software you need is a VNC client. There are many choices, but I would recommend the TightVNC client because of its simplicity all you need to get is tightvnc You may want to keep these two programs on a USB flash drive so you can easily run them from any computer.
Start by running PuTTY. You need to create a tunnel from port to Click open and log in. Once PuTTY is logged in you have a shell.You seem to have CSS turned off. Please don't fill out this field.

Normally a virtual X session Xvfb is created for each user, but it also works with X sessions on physical hardware. I wrote x11vnc back in because x0rfbserver was basically impossible to build on Solaris and had poor performance.
I also created enhancements to improve the interactive response, added many features, and etc. Do check the FAQ and this page first; I realize the pages are massive, but you can often use your browser's find-in-page search action using a keyword to find the answer to your problem or question. The certificate files should be deleted and recreated on a non-Debian system or an updated one.
If you are trying to follow someone's link to an FAQ once on this page it is now a broken link. Try inserting the string " faq. Background: VNC Virtual Network Computing is a very useful network graphics protocol applications running on one computer but displaying their windows on another in the spirit of X, however, unlike X, the viewing-end is very simple and maintains no state. It is a remote framebuffer RFB protocol. For Unix, the traditional VNC implementation includes a "virtual" X11 server Xvnc usually launched via the vncserver command that is not associated with a physical display, but provides a "fake" one X11 clients xtermfirefoxetc.
A remote user then connects to Xvnc via the VNC client vncviewer from anywhere on the network to view and interact with the whole virtual X11 desktop.
The VNC protocol is in most cases better suited for remote connections with low bandwidth and high latency than is the X11 protocol because it involves far fewer "roundtrips" an exception is the cached pixmap data on the viewing-end provided by X. Also, with no state maintained the viewing-end can crash, be rebooted, or relocated and the applications and desktop continue running. Not so with X Motif, GNOME, and similar applications that would yield very poor performance over a high latency link.
Howeversometimes one wants to connect to a real X11 display i. Maybe you want to close down an application cleanly rather than using killor want to work a bit in an already running application, or would like to help a distant colleague solve a problem with their desktop, or would just like to work out on the deck for a while. This is where x11vnc is useful. In this basic example let's assume the remote machine with the X display you wish to view is " far-away.
Step 0. Download x11vnc see below and have it available to run on far-away. Similarly, have a VNC viewer e. Step 1. By some means log in to far-away.
You can use sshor even rlogintelnetor any other method to do this. We do this because the x11vnc process needs to be run on the same machine the X server process is running on otherwise things would be extremely slow. Step 2. In that far-away. This step attaches x11vnc to the far-away.
If x11vnc does not have the authority to connect to the display it exits immediately. More on how to fix this below. If you suspect an X11 permissions problem do this simple test: while sitting at the physical X display open a terminal window gnome-terminal, xterm, etc. You should be able to run x11vnc successfully in that terminal without any need for command line options. If that works OK then you know X11 permissions are the only thing preventing it from working when you try to start x11vnc via a remote shell.
Then fix this with the tips below. End of Common Gotcha. When x11vnc starts up there will then be much chatter printed out use " -q " to quiet ituntil it finally says something like:.You seem to have CSS turned off. Please don't fill out this field.

Any VNC viewer should do the job and be compatible with the x11vnc server while not necessarily using all its functionalities. TigerVNC's vncviewer is a recommended client. Install x11vnc from the official repositories.
First, start X either by startx or through a display manager. You may need to set up X to run headless too. Then, run the following command, all available options are explained in x11vnc 1.
Another option is to place the x11vnc command line in a script which is called at login, for example:. You may set an X authority file for the VNC server. This is accomplished by using the -auth argument followed by the appropriate file, which will depend on how your X server was started.
Generally, assigning an X authority file requires running x11vnc as root. After reloading xinetd. To run x11vnc when system boots, create the override with systemctl edit x11vnc. The content should be like the following.
Replace the second ExecStart with the command you run interactively. Run systemctl enable x11vnc. Embedding this into a systemd.
By default, x11vnc will accept the first VNC session and shutdown when the session disconnects.
In order to avoid that, start x11vnc with either the -many or the -forever argument, like this:. Hit connect, and you should be set. You need to have SSH installed and configured.
Use the -localhost flag with x11vnc for it to bind to the local interface. The factual accuracy of this article or section is disputed. Xauthority directory. For the server to listen to the same TCP6 port, also use the -rfbportv6 option to force the IPv6 listening port. For example:. This article or section needs language, wiki syntax or style improvements. See Help:Style for reference. If you want to run x11vnc in GDM to login and then you want to run x11vnc in a GNOME shell user session for a "system-wide" x11vnc you can acomplish that with the following steps.
To fix this we need to create another systemd service that will start another x11vnc server in the GNOME Shell session assoon as you login.Villarreal's Pablo Fornals had to be taken to hospital after fainting during training and the midfielder will miss Sunday's LaLiga game against Barcelona as a result. Fornals made an "immediate recovery" but remains under observation in hospital, it was confirmed by the club on Saturday.

Soares missed the draw at Bournemouth with a hamstring injury, and hasn't recovered in time to face the Gunners at St Mary's. That will most likely mean Jeremy Pied continuing in the side. Barcelona injury problems appear to be easing with four key men all pictured in training ahead of their clash with Villarreal.
Ernesto Valverde welcomed Rafinha back into the fold for the first time since April, with the Brazilian defender having been sidelined with a serious knee problem. Ousmane Dembele also took part in the session as he works his way back from a hamstring injury, with the Frenchman easing into training earlier this week.

James Milner is likely to fill the vacancy for Sunday's Merseyside derby at home to Everton while captain Jordan Henderson is set to start in midfield after sitting out in midweek.
Senegalese international Cheikhou Kouyate will be sidelined for Saturday's EPL match against Chelsea. The West Ham midfielder injured a hamstring in Sunday's defeat at Manchester City and will also miss next Wednesday's home game against Arsenal.
Seattle Sounders midfielder Osvaldo Alonso has been ruled out of this weekend's MLS Cup final after failing a fitness test on Thursday.

UEFA announced on Thursday that Real Madrid defender Dani Carvajal will miss the holder's Champions League last-16 first leg tie after issuing a two game ban for appearing to deliberately pick up a booking.
Carvajal was shown a yellow card in the 90th minute for time wasting in the 6-0 win over APOEL. As it was his third, it ruled him out of Wednesday's victory over Dortmund, but in theory would have meant he was available for the round of 16 next February.
However, UEFA Control, Ethics and Disciplinary Body found that Carvajal had breached Article 15 of the Disciplinary Regulations.
Stoke manager Mark Hughes says Bruno Martins Indi will be out for up to eight weeks as he recovers from a groin injury. The Netherlands international had to be substituted during last weekend's 2-1 triumph over Swansea.
