vncinitconfig - VNC® Server setup utility
vncinitconfig resets VNC Server to factory defaults, and performs related auxiliary operations. ACTIONS apply to VNC Server in all modes unless otherwise stated.
Note that vncinitconfig -install-defaults is run automatically when VNC Server is installed, and numerous files are created; examine the script for details. If you wish to subsequently edit these files, it is recommended you do so in parallel .custom files; see the header at the top of each file for more information.
Note that if you do edit the original files and subsequently run vncinitconfig, any changes are overridden but preserved in files with a .old suffix.
- Performs all the actions below except -register-SELinux, -enable-system-xorg and -disable-system-xorg, where supported on the platform. It may be useful to perform this operation if VNC Server or any auxiliary application or file becomes corrupted.
Creates /etc/pam.d/vncserver or updates /etc/pam.conf, depending upon the version of PAM installed, to enable system authentication using PAM. By default, the pam_unix module is referenced to query passwords against the local database store only.
If you wish to query passwords against a directory service such as LDAP, you must reference an alternative module that provides this functionality. As a convenience, -pam additionally lists PAM modules (such as pam_ldap.so) found on your system; you must manually create /etc/pam.d/vncserver.custom or edit /etc/pam.conf to reference such a module.
Alternatively, for distributions such as Ubuntu with a common PAM configuration in /etc/pam.d/common-auth, set /etc/pam.d/vncserver.custom to:
@include common-auth @include common-account @include common-session
For distributions such as Red Hat with a common PAM configuration in /etc/pam.d/password-auth, set /etc/pam.d/vncserver.custom to:
auth include password-auth account include password-auth session include password-auth
- Creates /etc/vnc/xstartup to run a default virtual desktop environment for VNC Server in Virtual Mode. See vncserver-virtual.
- Creates /etc/vnc/config to specify default Xvnc options for VNC Server in Virtual Mode. See vncserver-virtual.
- Creates /etc/vnc/pulse/daemon.conf which will be read by the PulseAudio sound server when audio is played from within a Virtual Mode session. This prevents audio from the virtual sessions being directed to the physical speakers.
- Creates /etc/X11/vncserver-virtual-dummy.conf and /etc/X11/vncserver-virtual-vnc.conf to configure Xorg when VNC Server in Virtual Mode is used with SystemXorg enabled.
- Regenerates a private key for the root user. This key determines the identity of VNC Server in Service Mode and of the VNC Server in Virtual Mode daemon. Note you should ideally find out why the private key is missing or corrupt before performing this operation.
- Clears up old files related to licensing.
- -service-daemon, -virtual-daemon
- Installs an init file for the VNC Server in Service Mode or VNC Server in Virtual Mode daemon respectively. This will be a SystemV-style init script or systemd unit file as appropriate. See vncserver-x11-serviced, vncserver-virtuald.
- Registers the VNC backend with CUPS, on platforms where the VNC backend cannot be installed directly in the CUPS directory.
- Install firewalld service configuration files for VNC Service Mode and Virtual Mode daemons.
- Attempts to register SELinux modules that have been compiled onto the system. Required for the VNC Server in Service Mode and Virtual Mode daemons. Note this command is not run as part of -install-defaults.
- Enables SystemXorg for VNC Server in Virtual Mode. Run as root to enable for all users, or as a normal user to enable for just that user. When SystemXorg is enabled, VNC Server in Virtual Mode will use your system's installed Xorg instead of Xvnc. Note this command is not run as part of -install-defaults.
- Disables SystemXorg for VNC Server in Virtual Mode. Run as root to disable for all users, or as a normal user to disable for just that user. Note this command is not run as part of -install-defaults.
