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 behavior 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 charac-
ters are significant. Note that the stored password is not encrypted securely - anyone who has access to this file can trivially 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

Our current VNC setup is for only 1 user login, but this login can not access a few of the programs that I need. How can I add additional logins to VNC? I have only been able to find the logs in .vnc and the usr/bin scripts. (1 Reply)
