NAME
       vncpasswd - change the VNC password

SYNOPSIS
       vncpasswd [passwd-file]
       vncpasswd -f

DESCRIPTION
       vncpasswd  allows you to set the password used to access VNC desktops.  Its default behav-
       ior is to prompt for a VNC password and then store an obfuscated version of this  password
       to  passwd-file (or to $HOME/.vnc/passwd if no password file is specified.)  The vncserver
       script runs vncpasswd the first time you start a VNC desktop, and it invokes Xvnc with the
       appropriate  -rfbauth  option.  vncviewer can also be given a password file to use via the
       -passwd option.

       The password must be at least six characters long (unless the -f  command-line  option  is
       used--  see  below),  and  only the first eight characters are significant.  Note that the
       stored password is not encrypted securely - anyone who has access to this file  can  triv-
       ially  find  out the plain-text password, so vncpasswd always sets appropriate permissions
       (read and write only by the owner.)  However, when accessing a VNC desktop,  a  challenge-
       response  mechanism  is used over the wire making it hard for anyone to crack the password
       simply by snooping on the network.

OPTIONS
       -f     Filter mode.  Read a plain-text password from stdin and write an encrypted  version
	      to  stdout.   Note  that	in  filter  mode,  short  or even empty passwords will be
	      silently accepted.

FILES
       $HOME/.vnc/passwd
	      Default location of the VNC password file.
