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 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.
- 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.
A view-only password must be separated from the normal password by a newline character.
- Default location of the VNC password file.
VNC was originally developed by the RealVNC team while at Olivetti Research Ltd / AT&T Laboratories Cambridge. TightVNC additions were implemented by Constantin Kaplinsky. Many other people have since participated in development, testing and support. This manual is part of the TigerVNC software suite.
