26There are five programs here:
27
28 vncviewer - this is the VNC viewer, or client, program for X.
29
30 vncserver - this is a wrapper script which makes starting an X VNC
31 server (i.e. desktop) more convenient. It is written in
32 Perl, so to use the script you need that.
33
34 vncpasswd - this program allows you to change the password used to
35 access your X VNC desktops. The vncserver script uses
36 this program when you first start a VNC server.
37
38 vncconnect - this program tells a running instance of Xvnc to connect
39 to a listening VNC viewer (normally the connection is made
40 the other way round i.e. the viewer connects to Xvnc).
41
42 Xvnc - this is the X VNC server - it is both an X server and a VNC
43 server. You normally use the vncserver script to start Xvnc.
44
45
46First you must have a reasonably recent version of X installed (this includes
47/usr/openwin on Solaris machines). Also, TightVNC requires JPEG and zlib
48libraries installed in the system (e.g. under /usr/local). To build
49everything but Xvnc, do:
50
51 % xmkmf
52 % make World
53
54This should build first the vncauth library which is used by each of the
55programs, then vncviewer, vncpasswd and vncconnect.
56
57Xvnc differs from the other programs in that it is built inside a cut-down
58version of the X build tree. This is based around the XFree86 3.3.2 "server
59only" distribution, which in turn is based on the X11R6.3 distribution from
60the X consortium. To build Xvnc, do:
61
62 % cd Xvnc
63 % ./configure
64 % make
65
66If you have trouble building Xvnc, see the Xvnc/README file for more details.
67
68If it all builds OK you should copy the programs to some directory which
69is in your PATH environment variable, such as /usr/local/bin. Also, it's
70handy to install manual pages in a directory where the man utility can find
71them. You can use the vncinstall script to do this for you (man path is
72optional):
73
74 % cd ..
75 % ./vncinstall /usr/local/bin /usr/local/man
76
77If you want to use the Java VNC viewer, you should copy the class files from
78the classes directory to some suitable installation directory such as
79/usr/local/vnc/classes:
80
81 % mkdir -p /usr/local/vnc/classes
82 % cp classes/* /usr/local/vnc/classes
83
84We recommend that you use the vncserver script to run Xvnc for you. You can
85edit the script as appropriate for your site. Things you may need to change
86include:
87
88 * The location of Perl - if Perl is not installed in /usr/bin you'll need
89 to edit the "#!/usr/bin/perl" first line of vncserver.
90
91 * $vncClasses - this specifies the location of the Java classes for
92 the VNC viewer applet. The default is /usr/local/vnc/classes.
93
94 * Xvnc's font path and color database. If you have an installation of
95 X which is not in the standard place you may need to add arguments to the
96 Xvnc command line to set these. These should be appended to the $cmd
97 variable at the comment "# Add font path and color database...".
