Virtual	Network	Computing			     vncpasswd(1)



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 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 anyone to crack the password
     simply by snooping	on the network.


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