installation question / vnc setup
hi,
i am a new fedora9 user. i always confused about the usage of rpm and hope someone may clarify along with the VNC setup.
let me use vnc installation as an example. I downloaded vnc rpm package from the official web site and it was automatically saved to /home/henry .. ok then i cd to /home/henry and # rpm -i vnc* .. and it started the installation and seemed it was done.

now, i become having absolutely no idea where VNC was installed to. i couldn't find anything in my /bin, /sbin.. and finally i found my vncviewer under /usr/bin .. however i couldn't find vncserver after an hour of random search. Smilie

would someone please explain a bit how to specify path when trying to install rpm so i can find the stuffs after installation? Or please explain a bit how rpm packages got installed to different area in the system.

thanks a lot

vncserver

vncserver(1)						     Virtual Network Computing						      vncserver(1)

NAME

       vncserver - start or stop a VNC server

SYNOPSIS

       vncserver  [:display#] [-name desktop-name] [-geometry widthxheight] [-depth depth] [-pixelformat format] [-fp font-path] [-fg] [-autokill]
       [Xvnc-options...]
       vncserver -kill :display#

DESCRIPTION

       vncserver is used to start a VNC (Virtual Network Computing) desktop.  vncserver is a Perl script which simplifies the process of  starting
       an Xvnc server.	It runs Xvnc with appropriate options and starts a window manager on the VNC desktop.

       vncserver  can  be run with no options at all. In this case it will choose the first available display number (usually :1), start Xvnc with
       that display number, and start the default window manager in the Xvnc session.  You can also specify the display number, in which case vnc-
       server will attempt to start Xvnc with that display number and exit if the display number is not available.  For example:

	      vncserver :13

       Editing	the  file $HOME/.vnc/xstartup allows you to change the applications run at startup (but note that this will not affect an existing
       VNC session.)

OPTIONS

       You can get a list of options by passing -h as an option to vncserver.  In addition to the options listed below, any  unrecognised  options
       will be passed to Xvnc - see the Xvnc man page, or "Xvnc -help", for details.

       -name desktop-name
	      Each  VNC  desktop has a name which may be displayed by the viewer. The desktop name defaults to "host:display# (username)", but you
	      can change it with this option.  The desktop name option is passed to the xstartup script via the $VNCDESKTOP environment  variable,
	      which allows you to run a different set of applications depending on the name of the desktop.

       -geometry widthxheight
	      Specify the size of the VNC desktop to be created. Default is 1024x768.

       -depth depth
	      Specify  the  pixel  depth (in bits) of the VNC desktop to be created. Default is 24.  Other possible values are 8, 15 and 16 - any-
	      thing else is likely to cause strange behaviour by applications.

       -pixelformat format
	      Specify pixel format for Xvnc to use (BGRnnn or RGBnnn).	The default for depth 8 is BGR233 (meaning the most significant  two  bits
	      represent  blue,	the  next three green, and the least significant three represent red), the default for depth 16 is RGB565, and the
	      default for depth 24 is RGB888.

       -cc 3  As an alternative to the default TrueColor visual, this allows you to run an Xvnc server with a PseudoColor visual (i.e.	one  which
	      uses  a  color  map  or palette), which can be useful for running some old X applications which only work on such a display.  Values
	      other than 3 (PseudoColor) and 4 (TrueColor) for the -cc option may result in strange behaviour, and PseudoColor desktops must  have
	      an 8-bit depth.

       -kill :display#
	      This kills a VNC desktop previously started with vncserver.  It does this by killing the Xvnc process, whose process ID is stored in
	      the file "$HOME/.vnc/host:display#.pid".	The -kill option ignores anything preceding the first colon (":") in the display argument.
	      Thus, you can invoke "vncserver -kill $DISPLAY", for example at the end of your xstartup file after a particular application exits.

       -list  Lists running VNC servers.

       -fp font-path
	      If the vncserver script detects that the X Font Server (XFS) is running, it will attempt to start Xvnc and configure Xvnc to use XFS
	      for font handling.  Otherwise, if XFS is not running, the vncserver script will attempt to start Xvnc and allow Xvnc to use its  own
	      preferred method of font handling (which may be a hard-coded font path or, on more recent systems, a font catalog.)  In any case, if
	      Xvnc fails to start, the vncserver script will then attempt to determine an appropriate X font path for this system and  start  Xvnc
	      using that font path.

	      The -fp argument allows you to override the above fallback logic and specify a font path for Xvnc to use.

       -fg    Runs Xvnc as a foreground process.  This has two effects: (1) The VNC server can be aborted with CTRL-C, and (2) the VNC server will
	      exit as soon as the user logs out of the window manager in the VNC session.  This may be	necessary  when  launching  TigerVNC  from
	      within certain grid computing environments.

       -autokill
	      Automatically  kill  Xvnc  whenever the xstartup script exits.  In most cases, this has the effect of terminating Xvnc when the user
	      logs out of the window manager.

FILES

       Several VNC-related files are found in the directory $HOME/.vnc:

       $HOME/.vnc/xstartup
	      A shell script specifying X applications to be run when a VNC desktop is started.  If this file does not exist, then vncserver  will
	      create a default xstartup script which attempts to launch your chosen window manager.

       $HOME/.vnc/passwd
	      The VNC password file.

       $HOME/.vnc/host:display#.log
	      The log file for Xvnc and applications started in xstartup.

       $HOME/.vnc/host:display#.pid
	      Identifies the Xvnc process ID, used by the -kill option.
