NAME
       vncpasswd - change a VNC	password

SYNOPSIS
       vncpasswd [passwd-file]

DESCRIPTION
       vncpasswd  allows  you to set the password used to access VNC desktops.
       It stores an obfuscated version of  the	password  in  the  given  file
       (default	 $HOME/.vnc/passwd).   The vncserver script runs vncpasswd the
       first time you start a VNC desktop, and invokes Xvnc with the appropri-
       ate  -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, 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  trivially
       find  out  the plaintext	password, so vncpasswd always sets appropriate
       permissions (read and write only	by the owner).	However, when  access-
       ing  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.

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