Windows 7 and Kubuntu 10.04 no conenction

[dalamar]

Hi,

I have read the FAQ's and they were not helpful for the problem I am having. I did a search and got this error"Could not delete old search id sessions

DEBUG MODE

SQL Error : 1153 Got a packet bigger than 'max_allowed_packet' bytes"

So I am here.
I am running windows 7 (All firewalls off) on my laptop.
My home computer is running Kubuntu 10.04.
I have a Linksys wrt54gl running dd-wrt.

On the router I have forwarded all traffic on port 5903 to the proper computer at the same port.

On the Linux box I have x11vnc installed and listening on port 5903.

On the windows box I use PuTTY to connect to the router. That works fine.

When I try to use UltraVNC to connect, no matter if I connect to the LAN IP, the WAN IP, or localhost I immediately get connection failed.

From the PuTTY dialog box I can ping the computer just fine.
I tried earler with tightvnc and was getting an invalid protocol error.

Any suggestions you can make will be greatly apperciated.

Thanks

if you have x11vnc server on kubuntu
i suggest you use ssvnc viewer (Enhanced TightVNC Viewer) on your windows 7 optimized for connect to linux/unix/osx

or

try pure windows
ultra vncviewer 1.0.9.4 a lot of bugs are solved
start install and select viewer only
x32bit

x64bit

or
just update vncviewer.exe or/and winvnc.exe

Thanks for the suggestion. I would like to think that it makes some headway as I noticed something a little different.

I connect through PuTTY and all just fine. Then when I try to connect in, if I use localhost or my public IP and the right port it immediately fails. But, when I use the computers IP on the network and the port it takes a little longer like it is trying to connect and then fails to connect to server.

I tried the ssh/ssl version of vnc and got nothing with ssh. with ssl I got
an error fetching certificate.

i suggest you read both faq of SSVNC and x11vnc

http://www.karlrunge.com/x11vnc/faq.html#faq

http://www.karlrunge.com/x11vnc/ssvnc.html#quickstart

Q-51: How can I tunnel my connection to x11vnc via an encrypted SSH channel from Windows using an SSH client like Putty?

Thanks for the suggestion redge. They did help a little but still nothing.

If I choose localhost:0 now it tries to connect and takes longer but still comes back failed to connect.

you have now the uvnc 1.0.9.4 released
try with the new one if solve your issue.

otherwise, my knowledge about linux is stricly limited, almost 0 knowledge
your issue i don't really understand.

The new release did not change things. I am 98% sure this is not an issue with UltraVNC. I am just not sure where to look. I have been checking my router for connections on the port but I am not seeing anything in the logs. I am not sure if I don't establish a connection if it will show up in the log or not.
