vncinitconfig - VNC® Server setup utility


vncinitconfig ACTION...


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, 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 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(1).
Creates /etc/vnc/config to specify default Xvnc options for VNC Server in Virtual Mode. See vncserver-virtual(1).
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.
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, systemd unit file, or Solaris Service Management Facility manifest as appropriate. See vncserver-x11-serviced(1)vncserver-virtuald(1).
Registers the VNC backend with CUPS, on platforms where the VNC backend cannot be installed directly in the CUPS directory.
Attempts to register SELinux modules on systems with SELinux binaries. Required for the VNC Server in Service Mode and Virtual Mode daemons and printing. Note this command is not run as part of -install-defaults.
