The usage was quite +simple as you just run +``` +$ vncserver :x [vncserver options] [Xvnc options] +``` +and that was it. While this was working just fine, there were issues when users +wanted to start a Tigervnc server using *systemd*. For these reasons things were +completely changed and there is now a new way how this all is supposed to work. + + # How to start Tigervnc server +  +## Add a user mapping +With this you can map a user to a particular port. The mapping should be done in +`/etc/tigervnc/vncserver.users` configuration file. It should be pretty +straightforward once you open the file as there are some examples, but basically +the mapping is in form +``` +:x=user +``` +For example you can have +``` +:1=test +:2=vncuser +``` + +## Configure Xvnc options +To configure Xvnc parameters, you need to go to the same directory where you did +the user mapping and open `vncserver-config-defaults` configuration file. This +file is for the default Xvnc configuration and will be applied to every user +unless any of the following applies: +* The user has its own configuration in `$HOME/.vnc/config` +* The same option with different value is configured in +  `vncserver-config-mandatory` configuration file, which replaces the default +  configuration and has even a higher priority than the per-user configuration. +  This option is for system administrators when they want to force particular +  *Xvnc* options. + +Format of the configuration file is also quite simple as the configuration is +in form of +``` +option=value +option +``` +for example +``` +session=gnome +securitytypes=vncauth,tlsvnc +desktop=sandbox +geometry=2000x1200 +localhost +alwaysshared +``` +### Note: +There is one important option you need to set and that option is the session you +want to start. E.g when you want to start GNOME desktop, then you have to use +``` +session=gnome +``` +which should match the name of a session desktop file from `/usr/share/xsessions` +directory. + +## Set VNC password +You need to set a password for each user in order to be able to start the +Tigervnc server. In order to create a password, you just run +``` +$ vncpasswd +``` +as the user you will be starting the server for. +### Note: +If you were using Tigervnc before for your user and you already created a +password, then you will have to make sure the `$HOME/.vnc` folder created by +`vncpasswd` will have the correct *SELinux* context. You either can delete this +folder and recreate it again by creating the password one more time, or +alternatively you can run +``` +$ restorecon -RFv /home//.vnc +``` + +## Start the Tigervnc server +Finally you can start the server using systemd service. To do so just run +``` +$ systemctl start vncserver@:x +``` +as root or +``` +$ sudo systemctl start vncserver@:x +``` +as a regular user in case it has permissions to run `sudo`. Don't forget to +replace the `:x` by the actual number you configured in the user mapping file. +Following our example by running +``` +$ systemctl start vncserver@:1 +``` +you will start a Tigervnc server for user `test` with a GNOME session. + +### Note: +If you were previously using Tigervnc and you were used to start it using +*systemd* then you will need to remove previous *systemd* configuration files, +those you most likely copied to `/etc/systemd/system/vncserver@.service`, +otherwise this service file will be preferred over the new one installed with +latest Tigervnc. + +# Limitations +You will not be able to start a Tigervnc server for a user who is already +logged into a graphical session. Avoid running the server as the `root` user as +it's not a safe thing to do. While running the server as the `root` should work +in general, it's not recommended to do so and there might be some things which +are not working properly. diff --git a/SOURCES/tigervnc-1.3.1-do-not-die-when-port-is-already-taken.patch b/SOURCES/tigervnc-1.3.1-do-not-die-when-port-is-already-taken.patch deleted file mode 100644 index 3623b14..0000000 --- a/SOURCES/tigervnc-1.3.1-do-not-die-when-port-is-already-taken.patch +++ /dev/null @@ -1,14 +0,0 @@ -diff --git a/unix/vncserver b/unix/vncserver -index a6c890f..687ef72 100755 ---- a/unix/vncserver -+++ b/unix/vncserver -@@ -208,7 +208,8 @@ if ((@ARGV > 0) && ($ARGV[0] =~ /^:(\d+)$/)) { - $displayNumber = $1; - shift(@ARGV); - if (!&CheckDisplayNumber($displayNumber)) { -- die "A VNC server is already running as :$displayNumber\n"; -+ warn "A VNC server is already running as :$displayNumber\n"; -+ $displayNumber = &GetDisplayNumber(); - } - } elsif ((@ARGV > 0) && ($ARGV[0] !~ /^-/) && ($ARGV[0] !~ /^\+/)) { - &Usage(); diff --git a/SOURCES/tigervnc-CVE-2019-15691.patch b/SOURCES/tigervnc-CVE-2019-15691.patch deleted file mode 100644 index 1b0a6c8..0000000 --- a/SOURCES/tigervnc-CVE-2019-15691.patch +++ /dev/null @@ -1,116 +0,0 @@ -From d61a767d6842b530ffb532ddd5a3d233119aad40 Mon Sep 17 00:00:00 2001 -From: Pierre Ossman -Date: Tue, 10 Sep 2019 11:05:48 +0200 -Subject: [PATCH] Make ZlibInStream more robust against failures - -Move the checks around to avoid missing cases where we might access -memory that is no longer valid.

a VNC (Virtual Network Computing) desktop. +-.B vncserver +-is a Perl script which simplifies the process of starting an Xvnc server. It +-runs Xvnc with appropriate options and starts a window manager on the VNC +-desktop. +- +-.B vncserver +-can be run with no options at all. In this case it will choose the first +-available display number (usually :1), start Xvnc with that display number, +-and start the default window manager in the Xvnc session. You can also +-specify the display number, in which case vncserver will attempt to start +-Xvnc with that display number and exit if the display number is not +-available. For example: +- +-.RS +-vncserver :13 +-.RE +- +-Editing the file $HOME/.vnc/xstartup allows you to change the applications run +-at startup (but note that this will not affect an existing VNC session.) +- +-.SH OPTIONS +-You can get a list of options by passing \fB\-h\fP as an option to vncserver. +-In addition to the options listed below, any unrecognised options will be +-passed to Xvnc - see the Xvnc man page, or "Xvnc \-help", for details. +- +-.TP +-.B \-name \fIdesktop-name\fP +-Each VNC desktop has a name which may be displayed by the viewer. The desktop +-name defaults to "\fIhost\fP:\fIdisplay#\fP (\fIusername\fP)", but you can +-change it with this option. The desktop name option is passed to the xstartup +-script via the $VNCDESKTOP environment variable, which allows you to run a +-different set of applications depending on the name of the desktop. +-. +-.TP +-.B \-geometry \fIwidth\fPx\fIheight\fP +-Specify the size of the VNC desktop to be created. Default is 1024x768. +-. +-.TP +-.B \-depth \fIdepth\fP +-Specify the pixel depth (in bits) of the VNC desktop to be created. Default is +-24. Other possible values are 8, 15 and 16 - anything else is likely to cause +-strange behaviour by applications. +-. +-.TP +-.B \-pixelformat \fIformat\fP +-Specify pixel format for Xvnc to use (BGRnnn or RGBnnn). The default for +-depth 8 is BGR233 (meaning the most significant two bits represent blue, the +-next three green, and the least significant three represent red), the default +-for depth 16 is RGB565, and the default for depth 24 is RGB888. +-. +-.TP +-.B \-cc 3 +-As an alternative to the default TrueColor visual, this allows you to run an +-Xvnc server with a PseudoColor visual (i.e. one which uses a color map or +-palette), which can be useful for running some old X applications which only +-work on such a display. Values other than 3 (PseudoColor) and 4 (TrueColor) +-for the \-cc option may result in strange behaviour, and PseudoColor desktops +-must have an 8-bit depth. +-. +-.TP +-.B \-kill :\fIdisplay#\fP +-This kills a VNC desktop previously started with vncserver. It does this by +-killing the Xvnc process, whose process ID is stored in the file +-"$HOME/.vnc/\fIhost\fP:\fIdisplay#\fP.pid". The +-.B \-kill +-option ignores anything preceding the first colon (":") in the display +-argument. Thus, you can invoke "vncserver \-kill $DISPLAY", for example at the +-end of your xstartup file after a particular application exits. +-. +-.TP +-.B \-fp \fIfont-path\fP +-If the vncserver script detects that the X Font Server (XFS) is running, it +-will attempt to start Xvnc and configure Xvnc to use XFS for font handling. +-Otherwise, if XFS is not running, the vncserver script will attempt to start +-Xvnc and allow Xvnc to use its own preferred method of font handling (which may +-be a hard-coded font path or, on more recent systems, a font catalog.) In +-any case, if Xvnc fails to start, the vncserver script will then attempt to +-determine an appropriate X font path for this system and start Xvnc using +-that font path. +- +-The +-.B \-fp +-argument allows you to override the above fallback logic and specify a font +-path for Xvnc to use. +-. +-.TP +-.B \-fg +-Runs Xvnc as a foreground process. This has two effects: (1) The VNC server +-can be aborted with CTRL-C, and (2) the VNC server will exit as soon as the +-user logs out of the window manager in the VNC session. This may be necessary +-when launching TigerVNC from within certain grid computing environments. +-. +-.TP +-.B \-autokill +-Automatically kill Xvnc whenever the xstartup script exits. In most cases, +-this has the effect of terminating Xvnc when the user logs out of the window +-manager. +-. +-.TP +-.B \-noxstartup +-Do not run the %HOME/.vnc/xstartup script after launching Xvnc. This +-option allows you to manually start a window manager in your TigerVNC session. +-. +-.TP +-.B \-xstartup \fIscript\fP +-Run a custom startup script, instead of %HOME/.vnc/xstartup, after launching +-Xvnc. This is useful to run full-screen applications. +-. +-.TP +-.B \-list +-Lists all VNC desktops started by vncserver. +- +-.SH FILES +-Several VNC-related files are found in the directory $HOME/.vnc: +-.TP +-$HOME/.vnc/xstartup +-A shell script specifying X applications to be run when a VNC desktop is +-started. If this file does not exist, then vncserver will create a default +-xstartup script which attempts to launch your chosen window manager. +-.TP +-/etc/tigervnc/vncserver-config-defaults +-The optional system-wide equivalent of $HOME/.vnc/config. If this file exists +-and defines options to be passed to Xvnc, they will be used as defaults for +-users. The user's $HOME/.vnc/config overrides settings configured in this file. +-The overall configuration file load order is: this file, $HOME/.vnc/config, +-and then /etc/tigervnc/vncserver-config-mandatory. None are required to exist. +-.TP +-/etc/tigervnc/vncserver-config-mandatory +-The optional system-wide equivalent of $HOME/.vnc/config. If this file exists +-and defines options to be passed to Xvnc, they will override any of the same +-options defined in a user's $HOME/.vnc/config. This file offers a mechanism +-to establish some basic form of system-wide policy. WARNING! There is +-nothing stopping users from constructing their own vncserver-like script +-that calls Xvnc directly to bypass any options defined in +-/etc/tigervnc/vncserver-config-mandatory. Likewise, any CLI arguments passed +-to vncserver will override ANY config file setting of the same name. The +-overall configuration file load order is: +-/etc/tigervnc/vncserver-config-defaults, $HOME/.vnc/config, and then this file. +-None are required to exist. +-.TP +-$HOME/.vnc/config +-An optional server config file wherein options to be passed to Xvnc are listed +-to avoid hard-coding them to the physical invocation. List options in this file +-one per line. For those requiring an argument, simply separate the option from +-the argument with an equal sign, for example: "geometry=2000x1200" or +-"securitytypes=vncauth,tlsvnc". Options without an argument are simply listed +-as a single word, for example: "localhost" or "alwaysshared". +-.TP +-$HOME/.vnc/passwd +-The VNC password file. +-.TP +-$HOME/.vnc/\fIhost\fP:\fIdisplay#\fP.log +-The log file for Xvnc and applications started in xstartup. +-.TP +-$HOME/.vnc/\fIhost\fP:\fIdisplay#\fP.pid +-Identifies the Xvnc process ID, used by the +-.B \-kill +-option. +- +-.SH SEE ALSO +-.BR vncviewer (1), +-.BR vncpasswd (1), +-.BR vncconfig (1), +-.BR Xvnc (1) +-.br +-https://www.tigervnc.org +- +-.SH AUTHOR +-Tristan Richardson, RealVNC Ltd., D.
