It can connect to any VNC\-compatible server such ++as \fBXvnc\fR or WinVNC, allowing you to control desktop environment ++of a different machine. ++ ++You can use F8 to display a pop\-up utility menu. Press F8 twice to ++pass single F8 to the remote side. ++.SH OPTIONS ++.TP ++\fB\-help\fR ++Prints a short usage notice to stderr. ++.TP ++\fB\-listen\fR ++Make the viewer listen on port 5500+\fIdisplay\fR for reverse ++connections from a server. WinVNC supports reverse connections using ++the "Add New Client" menu option, or the \-connect command line ++option. \fBXvnc\fR requires the use of the helper program ++\fBvncconnect\fR. ++.TP ++\fB\-via\fR \fIgateway\fR ++Automatically create encrypted TCP tunnel to the \fIgateway\fR machine ++before connection, connect to the \fIhost\fR through that tunnel ++(TightVNC\-specific). By default, this option invokes SSH local port ++forwarding, assuming that SSH client binary can be accessed as ++/usr/bin/ssh. Note that when using the \fB\-via\fR option, the host ++machine name should be specified as known to the gateway machine, e.g. ++"localhost" denotes the \fIgateway\fR, not the machine where vncviewer ++was launched. See the ENVIRONMENT section below for the information on ++configuring the \fB\-via\fR option. ++.TP ++\fB\-shared\fR ++When connecting, specify that a shared connection is requested. In ++TightVNC, this is the default mode, allowing you to share the desktop ++with other clients already using it. ++.TP ++\fB\-noshared\fR ++When connecting, specify that the session may not be shared. This ++would either disconnect other connected clients or refuse your ++connection, depending on the server configuration. ++.TP ++\fB\-viewonly\fR ++Disable transfer of mouse and keyboard events from the client to the ++server. ++.TP ++\fB\-fullscreen\fR ++Start in full\-screen mode. Please be aware that operating in ++full\-screen mode may confuse X window managers. Typically, such ++conflicts cause incorrect handling of input focus or make the viewer ++window disappear mysteriously. See the grabKeyboard setting in the ++RESOURCES section below for a method to solve input focus problem. ++.TP ++\fB\-noraiseonbeep\fR ++By default, the viewer shows and raises its window on remote beep ++(bell) event. This option disables such behaviour ++(TightVNC\-specific). ++.TP ++\fB\-user\fR \fIusername\fR ++User name for Unix login authentication. Default is to use current ++Unix user name. If this option was given, the viewer will prefer Unix ++login authentication over the standard VNC authentication. ++.TP ++\fB\-passwd\fR \fIpasswd\-file\fR ++File from which to get the password (as generated by the ++\fBvncpasswd\fR(1) program). This option affects only the standard VNC ++authentication. ++.TP ++\fB\-encodings\fR \fIencoding\-list\fR ++TightVNC supports several different compression methods to encode ++screen updates; this option specifies a set of them to use in order of ++preference. Encodings are specified separated with spaces, and must ++thus be enclosed in quotes if more than one is specified. Available ++encodings, in default order for a remote connection, are "copyrect ++tight hextile zlib corre rre raw". For a local connection (to the same ++machine), the default order to try is "raw copyrect tight hextile zlib ++corre rre". Raw encoding is always assumed as a last option if no ++other encoding can be used for some reason. For more information on ++encodings, see the section ENCODINGS below. ++.TP ++\fB\-bgr233\fR ++Always use the BGR233 format to encode pixel data. This reduces ++network traffic, but colors may be represented inaccurately. The ++bgr233 format is an 8\-bit "true color" format, with 2 bits blue, 3 ++bits green, and 3 bits red. ++.TP ++\fB\-owncmap\fR ++Try to use a PseudoColor visual and a private colormap. This allows ++the VNC server to control the colormap. ++.TP ++\fB\-truecolour\fR, \fB\-truecolor\fR ++Try to use a TrueColor visual. ++.TP ++\fB\-depth\fR \fIdepth\fR ++On an X server which supports multiple TrueColor visuals of different ++depths, attempt to use the specified one (in bits per pixel); if ++successful, this depth will be requested from the VNC server. ++.TP ++\fB\-compresslevel \fIlevel\fR ++Use specified compression \fIlevel\fR (0..9) for "tight" and "zlib" ++encodings (TightVNC\-specific). Level 1 uses minimum of CPU time and ++achieves weak compression ratios, while level 9 offers best ++compression but is slow in terms of CPU time consumption on the server ++side. Use high levels with very slow network connections, and low ++levels when working over high\-speed LANs. It's not recommended to use ++compression level 0, reasonable choices start from the level 1. ++.TP ++\fB\-quality \fIlevel\fR ++Use the specified JPEG quality \fIlevel\fR (0..9) for the "tight" ++encoding (TightVNC\-specific). Quality level 0 denotes bad image ++quality but very impressive compression ratios, while level 9 offers ++very good image quality at lower compression ratios. Note that the ++"tight" encoder uses JPEG to encode only those screen areas that look ++suitable for lossy compression, so quality level 0 does not always ++mean unacceptable image quality. ++.TP ++\fB\-nojpeg\fR ++Disable lossy JPEG compression in Tight encoding (TightVNC\-specific). ++Disabling JPEG compression is not a good idea in typical cases, as ++that makes the Tight encoder less efficient. You might want to use ++this option if it's absolutely necessary to achieve perfect image ++quality (see also the \fB\-quality\fR option). ++.TP ++\fB\-nocursorshape\fR ++Disable cursor shape updates, protocol extensions used to handle ++remote cursor movements locally on the client side ++(TightVNC\-specific). Using cursor shape updates decreases delays with ++remote cursor movements, and can improve bandwidth usage dramatically. ++.TP ++\fB\-x11cursor\fR ++Use a real X11 cursor with X-style cursor shape updates, instead of ++drawing the remote cursor on the framebuffer. This option also ++disables the dot cursor, and disables cursor position updates in ++non-fullscreen mode. ++.TP ++\fB\-autopass\fR ++Read a plain-text password from stdin. This option affects only the ++standard VNC authentication. ++ ++.SH Enhanced TightVNC Viewer (SSVNC) OPTIONS ++.TP ++Enhanced TightVNC Viewer (SSVNC) web page is located at: ++.TP ++http://www.karlrunge.com/x11vnc/ssvnc.html ++.TP ++Note: ZRLE encoding is now supported. ++.TP ++Note: F9 is shortcut to Toggle FullScreen mode. ++.TP ++\fB\-use64\fR ++In \fB\-bgr233\fR mode, use 64 colors instead of 256. ++.TP ++\fB\-bgr222\fR ++Same as \fB\-use64\fR. ++.TP ++\fB\-use8\fR ++In \fB\-bgr233\fR mode, use 8 colors instead of 256. ++.TP ++\fB\-bgr111\fR ++Same as \fB\-use8\fR. ++.TP ++\fB\-16bpp\fR ++If the vnc viewer X display is depth 24 at 32bpp ++request a 16bpp format from the VNC server to cut ++network traffic by up to 2X, then tranlate the ++pixels to 32bpp locally. ++.TP ++\fB\-bgr565\fR ++Same as \fB\-16bpp\fR. ++.TP ++\fB\-grey\fR ++Use a grey scale for the 16- and 8\fB\-bpp\fR modes. ++.TP ++\fB\-alpha\fR ++Use alphablending transparency for local cursors ++requires: x11vnc server, both client and server ++must be 32bpp and same endianness. ++.TP ++\fB\-ycrop\fR n ++Only show the top n rows of the framebuffer.

The default is to not, mainly ++because most Linux, etc, systems X servers disable ++*all* Backingstore by default. To re\fB\-enable\fR it put ++Option "Backingstore" ++in the Device section of /etc/X11/xorg.conf. ++In \fB\-bs\fR mode with no X server backingstore, whenever an ++area of the screen is re\fB\-exposed\fR it must go out to the ++VNC server to retrieve the pixels. This is too slow. ++In \fB\-nobs\fR mode, memory is allocated by the viewer to ++provide its own backing of the main viewer window. This ++actually makes some activities faster (changes in large ++regions) but can appear to "flash" too much. ++.TP ++\fB\-noshm\fR ++Disable use of MIT shared memory extension (not recommended) ++.TP ++\fB\-termchat\fR ++Do the UltraVNC chat in the terminal vncviewer is in ++instead of in an independent window. ++.TP ++\fB\-unixpw str\fR ++Useful for logging into x11vnc in -unixpw mode. "str" is a ++string that allows many ways to enter the Unix Username ++and Unix Password. These characters: username, newline, ++password, newline are sent to the VNC server after any VNC ++authentication has taken place. Under x11vnc they are ++used for the -unixpw login. Other VNC servers could do ++something similar. ++You can also indicate "str" via the environment ++variable SSVNC_UNIXPW. ++Note that the Escape key is actually sent first to tell ++x11vnc to not echo the Unix Username back to the VNC ++viewer. Set SSVNC_UNIXPW_NOESC=1 to override this. ++If str is ".", then you are prompted at the command line ++for the username and password in the normal way. If str is ++"-" the stdin is read via getpass(3) for username@password. ++Otherwise if str is a file, it is opened and the first line ++read is taken as the Unix username and the 2nd as the ++password. If str prefixed by "rm:" the file is removed ++after reading. Otherwise, if str has a "@" character, ++it is taken as username@password. Otherwise, the program ++exits with an error.

The most common ++formats are 24 and 16 bit "true\-color" values, and 8\-bit "color map" ++representations, where an arbitrary map converts the color number to ++RGB values. ++ ++.I Encoding ++refers to how a rectangle of pixels are sent (all pixel information in ++VNC is sent as rectangles). All rectangles come with a header giving ++the location and size of the rectangle and an encoding type used by ++the data which follows. These types are listed below. ++.TP ++.B Raw ++The raw encoding simply sends width*height pixel values. All clients ++are required to support this encoding type. Raw is also the fastest ++when the server and viewer are on the same machine, as the connection ++speed is essentially infinite and raw encoding minimizes processing ++time. ++.TP ++.B CopyRect ++The Copy Rectangle encoding is efficient when something is being ++moved; the only data sent is the location of a rectangle from which ++data should be copied to the current location. Copyrect could also be ++used to efficiently transmit a repeated pattern. ++.TP ++.B RRE ++The Rise\-and\-Run\-length\-Encoding is basically a 2D version of ++run\-length encoding (RLE). In this encoding, a sequence of identical ++pixels are compressed to a single value and repeat count. In VNC, this ++is implemented with a background color, and then specifications of an ++arbitrary number of subrectangles and color for each. This is an ++efficient encoding for large blocks of constant color. ++.TP ++.B CoRRE ++This is a minor variation on RRE, using a maximum of 255x255 pixel ++rectangles. This allows for single\-byte values to be used, reducing ++packet size. This is in general more efficient, because the savings ++from sending 1\-byte values generally outweighs the losses from the ++(relatively rare) cases where very large regions are painted the same ++color. ++.TP ++.B Hextile ++Here, rectangles are split up in to 16x16 tiles, which are sent in a ++predetermined order. The data within the tiles is sent either raw or ++as a variant on RRE. Hextile encoding is usually the best choice for ++using in high\-speed network environments (e.g. Ethernet local\-area ++networks). ++.TP ++.B Zlib ++Zlib is a very simple encoding that uses zlib library to compress raw ++pixel data. This encoding achieves good compression, but consumes a ++lot of CPU time. Support for this encoding is provided for ++compatibility with VNC servers that might not understand Tight ++encoding which is more efficient than Zlib in nearly all real\-life ++situations. ++.TP ++.B Tight ++Like Zlib encoding, Tight encoding uses zlib library to compress the ++pixel data, but it pre\-processes data to maximize compression ratios, ++and to minimize CPU usage on compression. Also, JPEG compression may ++be used to encode color\-rich screen areas (see the description of ++\-quality and \-nojpeg options above). Tight encoding is usually the ++best choice for low\-bandwidth network environments (e.g. slow modem ++connections). ++.SH RESOURCES ++X resources that \fBvncviewer\fR knows about, aside from the ++normal Xt resources, are as follows: ++.TP ++.B shareDesktop ++Equivalent of \fB\-shared\fR/\fB\-noshared\fR options.
