NAME

vncpasswd - change the VNC password 

SYNOPSIS

vncpasswd [passwd-file]
vncpasswd -f 

DESCRIPTION

vncpasswdallows you to set the password used to access VNC desktops. Its defaultbehavior is to prompt for a VNC password and then store an obfuscated versionof this password to passwd-file (or to $HOME/.vnc/passwd if no passwordfile is specified.) The vncserver script runs vncpasswd the firsttime you start a VNC desktop, and it invokes Xvnc with the appropriate-rfbauth option. vncviewer can also be given a password file touse via the -passwd option.

The password must be at least six characters long (unless the -fcommand-line option is used-- see below), and only the first eightcharacters are significant. Note that the stored password is notencrypted securely - anyone who has access to this file can trivially find outthe plain-text password, so vncpasswd always sets appropriate permissions(read and write only by the owner.) However, when accessing a VNC desktop, achallenge-response mechanism is used over the wire making it hard for anyone tocrack the password simply by snooping on the network.

 

OPTIONS

-f
Filter mode. Read a plain-text password from stdin and write an encryptedversion to stdout. Note that in filter mode, short or even empty passwordswill be silently accepted.

A view-only password must be separated from the normal password by a newlinecharacter.

 

FILES

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