Fedora Installation :: X11vnc : Tail: Cannot Watch /tmp/x11vnc.tray.*
Jun 18, 2011
By invoking x11vnc with the -gui tray option the TCL/TK GUI attempts to embed itself onto the system tray, but I encounter the error message "tail: cannot watch /tmp/x11vnc.tray.*", after the first settings dialog approved [clicked OK]. I believe that a package is still missing to be installed and this is not really a software bug. I use the XFCE version shipped along F15, and the GUI can be started but not as a docked-applet.

I am working with Ubuntu for the first time since school and it was an intro class. I am trying to setup a file server for part of a school project. I installed x11vnc and am trying to set the password. However everywhere I look says the file would be located at ~/.vnc/passwd. However when I ls from the home directory .vnc does not exist. When I type out vncpasswd ~/.vnc/passwd I get returned a message The program 'vncpasswd' can be found in the following packages:
* tightvncserver
* vnc4server
how I can get this setup? Am I using old information that is no longer accurate or am i messing this up somewhere?

How come on x11vnc, with Fedora 12 PPC/x86/x64, my screen sizes can't be greater than 800 x 600, and they don't update when I change them in Displays. On my Ubuntu installations the x11vnc screen sizes update and can be basically any size selectable in Monitors.

I am a linux novice with root access to an Ubunutn 10 VM which i connect to via putty. I want to connect to it via a GUI from windows xp so I have tried installing x11vnc on the machine and used realvnc from the xp client I have tried to install x11vnc on the machine as follows
sudo apt-get install x11vnc vnc-java"
x11vnc -storepasswd
iptables -A INPUT -p tcp -d 0/0 -s 0/0 --dport 5900 -j ACCEPT
iptables -A INPUT -p tcp -d 0/0 -s 0/0 --dport 5900 -j ACCEPT
[code]....
This seems to load ok but removes the shell prompt. I presume the server has started and is listening on the ports so i used another putty window to reconnect to my machine and ran sockstat -l and xllvnc is listening on the 2 ports. I then downloaded realvnc windows client and entered the hostname to connect If i entered just the hostname or hostname:5900 i get a timeout error but if i enter hostname:5800 i get 'connection refused' error

Im trying to get vnc working over ssh between my windows pc and ubuntu server 11.04 natty over the internet. I have setup everything and got it all running automatically at boot on ubuntu. From within the local network i can use ssvnc and connect from a 2003 server to the ubuntu machine fine. Remotely I can connect and verify password over ssh but after that it tries to start tightvnc and fails. The issues seem to be on the windows side establishing the local connection to the tunnel or something I'm not a guru and I apologize if this is a windows issue but i think its likely that its a networking problem i need to forward or open a port somewhere but i cant find any easy to understand instructions so far in getting this running
This is the output in the putty terminal after running ssvnc slightly modified ive taken out my real username and server address I use user@server:0 as the arguments for ssvnc
Code:
Looking up host "server"
Connecting to server-ip port 22
Server version: SSH-2.0-OpenSSH_5.8p1 Debian-1ubuntu3
We claim version: SSH-2.0-PuTTY_Release_0.60
Using SSH protocol version 2
[Code]...
Does anyone have any ideas why the connection fails at the point of using the tunnel? is it a problem on the ubuntu or windows side?

Using x11vnc server on Debian host, and TightVNC viewer client on Windows 7. All was working fine until a server host upgrade, from Wheezy to Jessie. Now, when I try to connect, TightVNC retrieves the certificate as normal, compares and accepts it, and starts stunnel. The next step would normally be to prompt for the VNC password.
Instead it gives an error:
ReadExact: Socket error while reading.
I'm guessing that some thing is missing or misconfigured after the Jessie upgrade, which broke many other things too, as Debian upgrades always seem to do. I have removed and reinstalled the x11vnc package, no effect.
The errors in the log file don't mean a lot to me.
The server is started with this command:
Code: Select allx11vnc -ssl -display :0 -usepw >>vnc-log 2>&1 &
If I start it up without the -ssl flag, and connect from the Windows system with a different client (Mobaxterm) it all goes well.
Relevant part (tail) of the server log file:
Code: Select allThe SSL VNC desktop is: myhost:0
PORT=5900
SSLPORT=5900
19/01/2016 12:31:10 SSL: accept_openssl(OPENSSL_VNC)

I upgraded to Lucid yesterday. All of them solved, except this one: when I connect to my kubuntu PC from a Windows PC and launch x11vnc on the remote and TightVNC on the local, it keeps repainting the window making it unusable. Nothing gets printed to the log when the repaintings occur. Using -noxdamage or -nowf doesn't change a thing. -ncache doesn't work (I get an "ERROR: No active KDE sessions!").

I'm creating a new thread based on this post by batagy:

So I have running x11vnc as service without any problem (running on Solaris 10 and SLES10 too). I'm using the x11vnc's inbuilt "user chooser" screen (that little black screen), these command line options:
x11vnc -inetd -unixpw -users unixpw= -display WAIT:cmd=FINDCREATEDISPLAY-Xvnc.xdmcp -env X11VNC_CREATE_GEOM=1248x900 (plus a couple of other options that are not interesting here)
My question is related to the wanted VNC screen size. By default, I set the defauls screen size to 1248x900, as can be seen above.
Currently , when a user want to personalize his/her screen size to be started, he can do it this way: when the small black authentication window is appearing first, after his username, he's entering a colon, then specify the wanted resolution in this format: geom=1600x1200.
My question: is it possible somehow to set automatically the preferred screen size, without entering this ":geom=1600x1200" string in the authentication window? I mean to set it per user, without modifying the service options. I mean, for example setting the X11VNC_CREATE_GEOM or FD_GEOM variables in the user's home ".profile" for example?

Opensuse 11.4 and Gnome
I cannot get x11vnc to start via ssh. I keep running in to this MIT magic cookie.
I have tried the -findauth and -auth guess but I am told .Xauthority is not set.
ps wwaux | grep auth which worked for me under KDE does not help.
I am using x11vnc so that I can export the active seesion :0

At the moment I'm running Putty on a windows box at work to SSH in and tunnel port 5900, then I execute
Code:
x11vnc -xkb -ncache 10 -safer -localhost -nopw -once -display :0
from the shell.
I run ssvnc and tell it to connect to localhost, and we're good for remote desktop.
The next step is to push my luck and see if I can get streaming audio as well.
ssvnc is supposed to automate many of the required processes, making the use of a standalone ssh client like Putty redundant - it bundles a similar program, passing commands through ssh from its GUI
Under options/advanced it has a facility to 'Enable ESD/ARTSD' audio tunnelling and it bundles a windows-executable (using cygwin library) version of ESD, so it just needs some configuration.
When you click that option there's a documentation pane that says you can put
Quote:
esddsp -s localhost:16001 gnome-session
in your ~/.xsession startup file but since I use my Lucid box for local sound as well I'm not sure that's ideal as I want to use JACK, etc. and it looks like this command would route all audio to network, all the time.
ssvnc suggests using "x11vnc -create" mode to start it up in a virtual X session through Xvfb but it doesn't really go into any more detail as to how you do this.
I've installed Xvfb through synaptic, and that's as far as I've gotten.

I have looked around and haven't had a lot of luck finding any information on this. I could be blind...but I'm not sure, haha.
I do a lot of remote support for my clients (I do PC repairs and training). I have recently starting suggesting to some of my basic users that they give Ubuntu a try. So far it has been very well received and they are loving it. The problem I am running into is that some of them use laptops in multiple places, and some use routers that are not easily configured. In each case it makes port forwarding a large pain in the behind to allow for remote access.
I have started using the X11vnc reverse connection and it has been working well, except for the fact that it is using high quality color depth (24bit I think?). I know when starting the connection from my end I can set the color depth, but is there any way to set the depth of a reverse connection?
Also, I understand that using just vnc over the Internet is not secure. I need to look into a decent guide to set up SSH tunneling for this. I don't suppose anyone knows of a good guide for 10.04 and 10.10?

I'm launching it as follows: x11vnc -nomodtweak -scale 9/10 I can log in using my Windows box and UltraVNC and use input with no problem.

Before we use CentOS 4 and all work fine. We start x11vnc by ssh like root. And after this connect by client login in X screen. In CentOS 5 this way don't work. For connect we must login by local from keyboard, start x11vnc ssh by logined local user, and after this we may work, but can't change users.

I want to access my desktop from my laptop over the internet, after a while I found this [URL] so I followed the instructions "Access your PC over the internet" and "Logging in from another Ubuntu PC". Everything goes well until I try to run the shell script and get this: laptopuser@123.456.7.890's password:
I tried my luck with the passphrase associated with the rsa key, with the password of the laptopuser@laptop and with the password of the desktopuser@desktop but I keep getting Permission Denied (publickey, password).

I have a virtual private server that I am trying to connect to using x11vnc. I ran this through ssh to setup gnome
sudo apt-get install gnome-core
sudo apt-get install gdm
sudo /etc/init.d/gdm start
sudo dpkg-reconfigure xserver-xorg
I later ran sudo apt-get install ubuntu-desktop to see if that would help.
Code:
#cat /etc/issue
Ubuntu 10.04.1 LTS
l
Code:
#sudo startx
Fatal server error:
xf860OpenConsole: Cannot open /dev/tty0 (No such file or directory)
I assume this is because it probably doesn't have a video card.

I have x11vnc server set up on my desktop PC. I can boot the computer and connect at the login screen if I want to. I can login to my computer as usual. But after about 1 minute of logging in, the computer logs off as if pressing Ctrl+Alt+Backspace and returns me to the login screen. This cycle repeats when I login and I have to kill the x11vnc process or remove the command from /etc/gdm/Init/Default.Have tried so many things now but the end result is the same. I have Ubuntu 10.10 fully updated and x11vnc 9.10-1 from the default repos. I am using the following command in the /etc/gdm/Init/Default file:
Code:
/usr/bin/x11vnc -rfbauth ~/.vnc/passwd -rfbport 5901 -display :0 -forever -bg
I don't think it matters now whether I add KillInitClients=false into /etc/gdm/gdm.conf-custom or /etc/gdm/gdm.conf because of the x11vnc version I have. The manual says its not really needed. But I have tried this too with no better luck.The computer will still log me out after about a minute of logging in. It can be between 1 min to 1.5 mins.Running out of ideas and have tried the -noxfixes and -reopen commands.
Why does x11vnc crash out (or it may be gdm or x server?) after about a minute of logging in? If I am currently viewing my desktop through VNC viewer on another computer, it will still crash out after 1 min of log in, and lose the connection. I can reconnect through VNC again but I have to log back in to the remote computer and it will just log out after another minute.At last, in 2 days I have finally solved it. As simple as creating my own version. The x11vnc 9.10-1 version my default Ubuntu 10.10 repos is buggy. Here's my fix (I used this site):
1. Downloaded latest x11vnc dev build from above site (x11vnc-0.9.13-dev.tar.gz at time of posting)
2. Extract it
3. Open Terminal > sudo -s > enter admin password
4. cd LocationOfExtracted folder

Sorry if this is in the wrong group but its a bit of an odd one but I think comes under Server Support.. I've set up both x11vnc and freenx in an attempt to eliminate either as a cause for this issue. The problem is that when I log in with either, I can get into the desktop and run things from the menus but when I make the System menu active - the session hangs and you have to killall for the freenx or vnc processes.
I was wondering if anyone might be able to help me investigate this and hopefully fix it as I'm not sure where to look given that both types of remote connection seem to have the same issue.

I am having troubles with my printer.
I have to use the manual feed, as the tray jams.
When set to manual feed, it prints fine in B&W and color.
However, page 2 goes from manual to tray 1! One page at a time works great.
FC 13, recent install, Dell 3100 cn printer USB.

I was using Opensuse on Virtualbox earlier today. I issued the tail -f /var/log/messages command on Opensuse 11.3 to see the messages. Then I logged in from my Mac into Opensuse 11.3. I noticed that Opensuse was displaying realtime messages of the things happening. For eg, I entered a wrong su password and it displayed that too. But no such things were happening on my Fedora 13 installation. So is there any way if I could get some realtime messages on Fedora 13 too like the one on Opensuse..?
