NAME¶
vncpasswd - change a VNC password
SYNOPSIS¶
vncpasswd [
passwd-file]
DESCRIPTION¶
vncpasswd allows you to set the password used to access VNC desktops. It
stores an obfuscated version of the password in 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 use via the
-passwd option.
The password must be at least six characters long, 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 plaintext 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.
FILES¶
- $HOME/.vnc/passwd
- Default location of the VNC password file.
