Vncpasswd allows you to set the password used to access VNC desktops. Its default behavior is toprompt 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 isspecified.) 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 characters aresignificant. Note that the stored password is not encrypted securely - anyone who has access to this file can trivially find out the plain-textpassword, 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 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 willbe silently accepted.
