REPOSTED with Zebedee Configs...Running VNC over a Zebedee'd Conn ection

Matt:

Looking at your configuration logs, I notice that your server configuration
file has a "serverport 443" entry, yet there is no corresponding entry in
your client configuration file.  If you do not specify a port on the client
side, it will default to port 11965. Also, the command line for your client
looks like it needs a bit of tweaking. 

Perhaps if you simplify your setup things will go better for you.  Here is
my setup.  I like to connect to my home system from work during the day.
Notice that since I don't specify any ports in my config file, all my
zebedee traffic happens over port 11965.

My Home system is running the Zebedee server, waiting for incoming
connections.  It is also running VNC server with the "AllowLoopback" option
set in the registry.  Here is the server configuration file that I use:

=== Begin Config File ===
	#
	# Zebedee server configuration file
	#

	verbosity 2		# Slightly more than basic messages

	server true		# Yes, it's a server!
	detached true		# Run detached from terminal
	udpmode false		# Are we operating in UDP mode?
	timestamplog true

	logfile 'C:\progra~1\zebedee\server.log'

	keygenlevel 2		# Generate maximum strength private keys

	redirect "telnet ftp"		# Basic services
	redirect 5900-5950		# VNC Traffic
	redirect 5500			# VNC reverse traffic

	targethost localhost		# Redirection is to the local
machine

	compression zlib:9		# Allow maximum zlib compression
	keylength 256			# Allow keys up to 256 bits
	keylifetime 36000		# Shared keys last 10 hours
	maxbufsize 16383		# Allow maximum possible buffer size

=== End config File ===

Then on my work system, I do not use a configuration file.  Instead I have
made a shortcut with the following command line on it.  (lines may wrap but
should all be on one line:

"C:\Program Files\Zebedee\zebedee.exe" -e "C:\Progra~1\ORL\VNC\vncviewer.exe
localhost:5 /8bit /scale 7/8" 5905:your.home.system.ip.address.here:5900

When I run the above command line, the zebedee client starts, connects to my
home IP address and then runs the vnc viewer.  

That should do it.  If you have a firewall at work, you should still be able
to initiate an outgoing connection over port 11965.  If you have a firewall
at home, you'll need to open up port 11965 in order to let zebedee traffic
in.

Make sure you have the latest version of Zebedee as well.  Here is the web
site for it:  http://www.winton.org.uk/zebedee/

Hope this helps!

-Mike

Conn ection


When I attempt to connect to the Zebedee server with the client, the only
error I get in my logs is the following:

zebedee(266/215): 2001-06-05-16:37:06:  waiting for client connection
zebedee(266/215): 2001-06-05-16:37:07:  accepted connection from 127.0.0.1
zebedee(266/215): 2001-06-05-16:37:07: ERROR: server refused request for
redirection to titan:443

My configuration files are below.

The name of the box I am running the Zebedee server on is named Titan, and I
am attempting to connect to it on port 443 (on Titan).  I believe this error
is due to my misconfiguration of the Zebedee client-piece.  Could anyone
tell me how to fix this?

Thank you!
