It can connect to any VNC\-compatible server such -+as \fBXvnc\fR, WinVNC, or \fBx11vnc\fR, allowing you to control desktop environment -+of a different machine. -+ -+ssvncviewer is an enhanced version of the tightvnc unix viewer that can -+take advantage of features in the \fBx11vnc\fR and UltraVNC VNC servers. -+See below for the description of these features. -+ -+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 and ZYWRLE encodings are now supported. -+.TP -+Note: F9 is shortcut to Toggle FullScreen mode. -+.TP -+Note: In -listen mode set the env var. SSVNC_MULTIPLE_LISTEN=1 -+to allow more than one incoming VNC server at a time. -+.TP -+Note: If the host:port is specified as "exec=command args..." -+then instead of making a TCP/IP socket connection to the -+remote VNC server, "command args..." is executed and the -+viewer is attached to its stdio. This enables tunnelling -+established via an external command, e.g. an stunnel(8) -+that does not involve a listening socket. -+This mode does not work for -listen reverse connections. -+.TP -+Note: If the host:port contains a '/' it is interpreted as a -+unix-domain socket (AF_LOCAL insead of AF_INET) -+.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. For -+use with x11vnc \fB\-ncache\fR client caching option -+to help "hide" the pixel cache region. -+Use a negative value (e.g. \fB\-1\fR) for autodetection. -+Autodetection will always take place if the remote -+fb height is more than 2 times the width. -+.TP -+\fB\-sbwidth\fR n -+Scrollbar width for x11vnc \fB\-ncache\fR mode (\fB\-ycrop\fR), -+default is very narrow: 2 pixels, it is narrow to -+avoid distraction in \fB\-ycrop\fR mode. -+.TP -+\fB\-nobell\fR -+Disable bell. -+.TP -+\fB\-rawlocal\fR -+Prefer raw encoding for localhost, default is -+no, i.e. assumes you have a SSH tunnel instead. -+.TP -+\fB\-graball\fR -+Grab the entire X server when in fullscreen mode, -+needed by some old window managers like fvwm2. -+.TP -+\fB\-popupfix\fR -+Warp the popup back to the pointer position, -+needed by some old window managers like fvwm2. -+.TP -+\fB\-grabkbd\fR -+Grab the X keyboard when in fullscreen mode, -+needed by some window managers. Same as \fB\-grabkeyboard\fR. -+\fB\-grabkbd\fR is the default, use \fB\-nograbkbd\fR to disable. -+.TP -+\fB\-bs\fR, \fB\-nobs\fR -+Whether or not to use X server Backingstore for the -+main viewer window. 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\fR -+str Useful for logging into x11vnc in \fB\-unixpw\fR 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 \fB\-unixpw\fR 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. Got all that? -+.TP -+\fB-repeater\fR str This is for use with UltraVNC repeater proxy described -+here: http://www.uvnc.com/addons/repeater.html. The "str" -+is the ID string to be sent to the repeater. E.g. ID:1234 -+It can also be the hostname and port or display of the VNC -+server, e.g. 12.34.56.78:0 or snoopy.com:1. Note that when -+using -repeater, the host:dpy on the cmdline is the repeater -+server, NOT the VNC server. The repeater will connect you. -+Example: vncviewer ... -repeater ID:3333 repeat.host:5900 -+Example: vncviewer ... -repeater vhost:0 repeat.host:5900 -+.TP -+\fB\-printres\fR Print out the Ssvnc X resources (appdefaults) and -+then exit. You can save them to a file and customize them (e.g. the -+keybindings and Popup menu) Then point to the file via -+XENVIRONMENT or XAPPLRESDIR. -+.TP -+\fB New Popup actions:\fR -+ -+ ViewOnly: ~ -viewonly -+ Disable Bell: ~ -nobell -+ Cursor Shape: ~ -nocursorshape -+ X11 Cursor: ~ -x11cursor -+ Cursor Alphablend: ~ -alpha -+ Toggle Tight/ZRLE: ~ -encodings ... -+ Toggle ZRLE/ZYWRLE: ~ -encodings zywrle... -+ Quality Level ~ -quality (both Tight and ZYWRLE) -+ Compress Level ~ -compresslevel -+ Disable JPEG: ~ -nojpeg (Tight) -+ Full Color ~ as many colors as local screen allows. -+ Grey scale (16 & 8-bpp) ~ -grey, for low colors 16/8bpp modes. -+ 16 bit color (BGR565) ~ -16bpp / -bgr565 -+ 8 bit color (BGR233) ~ -bgr233 -+ 256 colors ~ -bgr233 default # of colors. -+ 64 colors ~ -bgr222 / -use64 -+ 8 colors ~ -bgr111 / -use8 -+ Set Y Crop (y-max) ~ -ycrop -+ Set Scrollbar Width ~ -sbwidth -+ -+ UltraVNC Extensions: -+ -+ Set 1/n Server Scale Ultravnc ext.

Try to prevent input and -+ viewing of monitor at physical display. -+ -+ Note: the Ultravnc extensions only apply to servers that -+ support them. x11vnc/libvncserver supports some of them. -+ -+.SH ENCODINGS -+The server supplies information in whatever format is desired by the -+client, in order to make the client as easy as possible to implement. -+If the client represents itself as able to use multiple formats, the -+server will choose one. -+ -+.I Pixel format -+refers to the representation of an individual pixel. 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). -+.TP -+.B ZRLE -+The SSVNC viewer has ported the RealVNC (www.realvnc.com) ZRLE encoding -+to the unix tightvnc viewer. -+.TP -+.B ZYWRLE -+The SSVNC viewer has ported the Hitachi lossy wavelet based ZRLE -+encoding from http://mobile.hitachi-system.co.jp/publications/ZYWRLE/ -+to the unix tightvnc viewer. -+.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.
