       vncpasswd - change a VNC password

       vncpasswd [passwd-file]

       vncpasswd allows you to set the password used to access VNC desktops.  It stores an obfus-
       cated version of the password in the given file	(default  $HOME/.vnc/passwd).	The  vnc-
       server script runs vncpasswd the first time you start a VNC desktop, and 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, 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	accessing
       a VNC desktop a challenge-response mechanism is used over the wire making it hard for any-
       one to crack the password simply by snooping on the network.

	      Default location of the VNC password file.
