Somehow I can't seem to find the answer in the archives, but is it
possible to use VNC through a firewall?
At my work I can't get access to my computer at home because of the
company firewall.

Probably not. I have the same situation at my work.
Corporations tend to have what's called packet
sniffers installed. They can determine what type of
data is being sent and then either block it or allow
it through.
Until a few months ago people could VPN or VNC between
home and work. But
Hi Everyone
I wonder if anyone knows if there are any command line switches which I
could use to roll out VNC, with which we could specify installation options,
and not worry the user about clicking and entering parameters.
Any help would be appreciated. Thanks in advance.

Brian
Jimmy,
In general that's not advisable with the GPL release, which doesn't encrypt
network traffic. You should either access your VNC systems via a secure
tunnel such as SSH, or look at the new VNC Enterprise Edition
(http://www.realvnc.com/products/enterprise), to be released shortly... :)

Brian,
We're using InnoSetup for the installer, so the /silent and /verysilent
flags will work will do a default (server + viewer) install. You can then
separately apply registry settings to configure the server, if required.
Alternatively VNC Enterprise Edition
Scott,
The original post on the subject remains valid - the ZRLE encoder includes a
sanity check to prevent excessive resource usage by the Zlib algorithm and
unfortunately the current release tries to be a little *too* sane,
preventing very large desktops from working correctly.

We were running an FTP server in our company on a Windows XP

You can run through a firewall if you can get your IT folks to specifically accept VNC
traffic.
Suggest you use SSH tunneling (http://www.uk.research.att.com/archive/vnc/sshvnc.html)
if
they're amenable.

Windows XP sp2 installs and enables a firewall. you need to make
exceptions for it using this tool. When these instructions tell you
to browse to the program you need to locate winvnc4.exe (default

Does the enterprise eddition support file transfer?
what about modem support?
is there a feature list some where that I can view?
Currently we are using Net-Op (an old version) but I really like the
possible security and performance and stability is better with vnc.
Additionally is there a

Dear all,
I foud something, that answers in someway my questions/problem, but I
really do not know, what I have do to or can do!
My Server is at home is W2K3 and here in the office we have W2K Sp
4.
When I'm using the Viewer at home (WXP sp 2) it works perfectly.
This may be related to SP2 issue that a recent fix has been put out for by
MS.

Thanks, Stuart, this particular station is still @ SP1, fully patched.
One note: If I do not register VNC Server as a service during install, but
trigger the manual mode from a shortcut in the Startup folder, it binds to
the correct IP every time. I can only assume that some other program
Hi Stuart,
My experiences with VNC Server re binding are mainly to do with using VNC as
a service on a dial up connexion. The binding occurs before you are
connected thus you only have your Network Interface Card default IP.
Once connected I usually have to Stop Start the VNC service to rebind.
Max,
Could it be possible the Wireless LAN is intermittantly going offline/online
just a thought as if it was then you have an intermittant network problem ??

Dear all on the VNC list.. I remember earlyer righting about screen readers
and the VNC viewer. After confirming with a visionally impaired computer user,
that the viewer either Java or not, is really inaccessible. He said that yes,
typing keyboard events into the viewer will work, but he
Im pretty sure your IT people have port 21 open so your desktop support guys
can down load from IBM, HP and so on/s FTP. Change your VNC server to accept
connetions on port 21. Then have your viewer send the request to port 21

Even though ftp (port 21) traffic may not be blocked.
Modern firewalls rely on other means (i.e. stateful inspection) to
determine if the traffic is allowed.
while it is easy to redirect ports, any firewall costing over a few
hundred $, will still know that is non-web or non-ftp traffic and
I tried to run telnet to the machine running the vnc server at port 5901 and I
got RFB 003.003 instead of RFB 003.008. The VNC server is running on a Win2K

On the other hand I can see a Win 2003 server running VNC Server 4 and a Win
XP pro running VNC Server 3.3.7, both from the same machine
Quick patch for linux vncviewer to consult xinerama when going
fullscreen for 3.3.7. Adds '-screen' option to pick a xinerama screen,
and '-noxinerama' to disable xinerama support. Patch does not include
