Virtual Network Computing vncpasswd(1)
NAME
vncpasswd - change a VNC password
SYNOPSIS
/usr/bin/vncpasswd [passwd-file]
DESCRIPTION
vncpasswd allows you to set the password used to access VNC
desktops. It stores an obfuscated version of the passwordin the given file (default $HOME/.vnc/passwd). The
vncserver script runs vncpasswd the first time you start a
VNC desktop, and invokes Xvnc with the appropriate -rfbauth
option. vncviewer can also be given a password file to usevia the -passwd option.
The password must be at least six characters long, and only the first eight characters are significant. Note that thestored password is not encrypted securely - anyone who has
access to this file can trivially find out the plaintextpassword, so vncpasswd always sets appropriate permissions
(read and write only by the owner). However, when accessinga VNC desktop a challenge-response mechanism is used over
the wire making it hard for anyone to crack the password simply by snooping on the network. FILES$HOME/.vnc/passwd
Default location of the VNC password file.SEE ALSO
