I have a HP-UX machine at one site and a XP machine at a remote site. The
Unix box runs the vncserver and the viewer is on the XP box. The setup has
been preconfigured so that the XP machine can auto-login to the Unix box
as user A. I would like to change this setup so that it automatically logs
Greetings,
I have been using the free edition VNC on a Windows 2000 Server. It has worked
quite well. All of a sudden if I try to log into this server from home, it
will flash open the desktop of the server I am trying to connect to then
instantly close. No warning message or anything. I am th

Hi list,
Bear with me I'm new to the whole vnc concept on linux.
I've been able to activate the vnc server in my linux X11 server by
adding the following to the module section:
load"vnc"
I'm able to connect with the vncviewer program from a windows host and a
linux host all ok.
If I run nmap

Another factor worth considering is the size of the LZMA dictionary,
which is determined when initializing the compressor. The dilemma here
is that a larger dictionary leads to a better compression ratio,
especially when the data contains much repetition (e.g. many similar
After reading LZMA docs, it appears that it would be better to use the
U32 and PIXEL types in my proposed encoding, instead of U16 and CPIXEL.
This way, assuming the common 32-bit true-color pixel format is used,
the encoding guarantees 32-bit alignment at all levels. According to
the LZMA do

Text compresses well because it is just black on white. Multicolored
backgrounds do not but if you running vnc you should turn all of these off.

I was referring to the dictionary maintained by the LZMA codec, if VNC
were to use LZMA compression. I noticed that in the ZRLE encoding, a

Does vnc accumulate dictionary between frame updates? I would think not
because you would not be able to join an existing session.
Also things vnc compresses are mostly flat color surfaces which compress
well with most any method.
I found most slowness during vnc session on windows comes not from

You don't neet to change VNC port if your router can forward any port to
any other port (a lot of routers do). Just install vnc as usual and
forward ports from the router to different ip addresses.
5900 - IP1:5900
5901 - IP2:5900
5902 - IP3:5900
etc.

Bengt,
FD_ZERO is a macro used to initialise an fd_set structure prior to using
select(). These are OS-provided, so if they won't compile then this
suggests that you're using the wrong headers for the target.

In this page:

it's written black on white that "Note that the HTTP port number cannot
be set to the same value as that used for incoming VNC connections."

Compiling for ARM using SnapGear Embedded toolchain I get the following error
when building in the "unix" directory

Have sorted it. I had both the VNC viewer program and the Java viewer set
to listen on port 5900. As soon as I set the java viewer back to 5800 and
opened it on the firewall, all is good.
I thought that both could be set to listen on the same port but I must be
wrong.
Thanks for the responses g
