NAME
vncpasswd - set passwords for VNC server SYNOPSIS
vncpasswd [file] vncpasswd -t vncpasswd -f 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 command-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 util- ity 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 $HOME/.vnc/ directory will be created if it does not exist. Each password has to be longer than five characters (unless the -f command-line option was used, see its description below). Only the first eight characters are significant. If the primary password is too short, the program will abort. If the view-only password is too short, then only the primary password will be saved. Unless a file name was provided in the command-line explicitly, this utility may perform certain sanity checks to prevent writing a pass- word file into some hazardous place. If at least one password was saved successfully, vncpasswd will exit with status code 0. Otherwise the returned status code will be set to 1. OPTIONS
-t Write passwords into /tmp/$USER-vnc/passwd, creating the /tmp/$USER-vnc/ directory if it does not exist, and checking the permis- sions on that directory (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). -f Filter mode. Read plain-text passwords from stdin, write encrypted versions to stdout. One or two passwords (full-control and view- only) can be supplied in the input stream, newline terminates a password. Note that in the filter mode, short or even empty pass- words will be silently accepted. SEE ALSO

NAME
vncserver - a wrapper to launch an X server for VNC. SYNOPSIS
vncserver [:display] [-geometry widthxheight] [-depth depth] [-pixelformat rgbNNN|bgrNNN] [-name desktop-name] [Xvnc-options...] vncserver -kill :display vncserver -help DESCRIPTION
vncserver is a wrapper script for Xvnc, the free X server for VNC (Virtual Network Computing). It provides all capabilities of a standard X server, but does not connect to a display for itself. Instead, Xvnc creates a virtual desktop you can view or control remotely using a VNC viewer. OPTIONS
You can add Xvnc options at the command line. They will be added to the invocation of Xvnc without changes. The options provided by the vncserver itself are as follows: :display The display number to use. If omitted, the next free display number is used. -geometry widthxheight Set desktop width and height. -depth depth Set the colour depth of the visual to provide, in bits per pixel. Must be a value between 8 and 32. -pixelformat rgbNNN|bgrNNN Set colour format for pixels representation. The viewer can do the conversion to any other pixel format, but it is faster if the depth and pixel format of the server is the same as the equivalent values on the viewer display. -name string This specifies the name of the desktop. -kill :display Stops the session running on the specified display. -help Prints a short usage notice to stderr. EXAMPLES
vncserver Invokes Xvnc on the next available display and with suitable defaults. vncserver :1 Invokes Xvnc on display :1. vncserver -geometry 800x600 -depth 16 :1 Invokes Xvnc on display :1 with desktop size of 800x600 pixels and color depth of 16 bits per pixel. vncserver -kill :1 Shuts down Xvnc server on display :1.
