vncpasswd(1) TightVNC vncpasswd(1)NAMEvncpasswd - set passwords for VNC server
SYNOPSISvncpasswd [file]
vncpasswd-t
DESCRIPTION
The vncpasswd utility should be used to create and change
passwords for the TightVNC server authentication. Xvnc
uses such passwords when started with the -rfbauth com-
mand-line option (or when started from the vncserver
script).
vncpasswd allows to enter either one or two passwords. The
first password is the primary one, the second password can
be used for view-only authentication. Xvnc will restrict
mouse and keyboard input from clients who authenticated
with the view-only password. The vncpasswd utility asks
interactively if it should set the second password.
The password file name defaults to $HOME/.vnc/passwd
unless the -t command-line option was used (see the
OPTIONS section below). The $HOME/.vnc/ directory will be
created if it does not exist.
Each password has to be longer than five characters. Only
the first eight characters are significant. If the primary
password is too short, the program will abort. If the
view-only password is too short, then only the primary
password will be saved.
Unless a file name was provided in the command-line
explicitly, this utility may perform certain sanity checks
to prevent writing a password file into some hazardous
place.
If at least one password was saved successfully, vncpasswd
will exit with status code 0. Otherwise the returned sta-
tus code will be set to 1.
OPTIONS-t Write passwords into /tmp/$USER-vnc/passwd, creat-
ing the /tmp/$USER-vnc/ directory if it does not
exist, and checking the permissions on that direc-
tory (the mode must be 700). This option can help
to improve security when your home partition may be
shared via network (e.g. when using NFS).
