tightvncpasswd

vncpasswd(1)							     TightVNC							      vncpasswd(1)

NAME

       vncpasswd - set passwords for VNC server

SYNOPSIS

       vncpasswd [file]
       vncpasswd -t
       vncpasswd -f

DESCRIPTION

       The  vncpasswd  utility should be used to create and change passwords for the TightVNC server authentication. Xvnc uses such passwords when
       started with the -rfbauth command-line option (or when started from the vncserver script).

       vncpasswd allows to enter either one or two passwords. The first password is the primary one, the second password can be used for view-only
       authentication. Xvnc will restrict mouse and keyboard input from clients who authenticated with the view-only password. The vncpasswd util-
       ity asks interactively if it should set the second password.

       The password file name defaults to $HOME/.vnc/passwd unless the -t command-line option was  used  (see  the  OPTIONS  section  below).  The
       $HOME/.vnc/ directory will be created if it does not exist.

       Each  password  has  to	be  longer than five characters (unless the -f command-line option was used, see its description below).  Only the
       first eight characters are significant. If the primary password is too short, the program will abort. If  the  view-only  password  is  too
       short, then only the primary password will be saved.

       Unless  a  file name was provided in the command-line explicitly, this utility may perform certain sanity checks to prevent writing a pass-
       word file into some hazardous place.

       If at least one password was saved successfully, vncpasswd will exit with status code 0. Otherwise the returned status code will be set	to
       1.

OPTIONS

       -t     Write  passwords	into  /tmp/$USER-vnc/passwd, creating the /tmp/$USER-vnc/ directory if it does not exist, and checking the permis-
	      sions on that directory (the mode must be 700). This option can help to improve security when your home partition may be shared  via
	      network (e.g. when using NFS).

       -f     Filter  mode. Read plain-text passwords from stdin, write encrypted versions to stdout. One or two passwords (full-control and view-
	      only) can be supplied in the input stream, newline terminates a password.  Note that in the filter mode, short or even  empty  pass-
	      words will be silently accepted.
