SSH tunnel + VNC + putty -> connection suspend - SSH

Hi,

I installed a SSH server on A.
I have putty and a VNC server on B.
With a VNC listener on A, i can control B (with "add new client").

But, when i want to edit current putty session with A & VNCviewer
(with a click on the icon in the upper left on the putty window), the
SSH tunnel suspends.
I have to ask to someone who is near the computer do "unblock" putty.

Is it normal ?
Have I to change an option ?

Sorry for my english

thx

I have done VNC through SSH.. with putty and without putty.

but I never changed settings during.

What icon are you referring to in the putty window? The putty window
that paunches when you I run putty.exe is a configuration screen

what setting did you change?

I don`t know much about the settings. But anyhow.

A person open putty & log to my ssh server.
When VNC is open, when i try to move putty's window or when i try to
click on the icon on the opened putty (with the prompt, the icon in
the upper bar), it seems that the connexion is suspended.

So i can't change any settings throw VNC ..

If you are just using VNC you don`t need that putty window with the
shell once you logged in. Can you minimise it?
Why try to change settings in the middle of the connection?

If you look here
this shows the options that OpenSSH client, an alternative to putty,
but it has the same options.
http://erdelynet.com/2002/10/02/ssh/vnc-through-ssh/
Putty has the same options. Try something like
c:\crp>putty -T -L 6000:127.0.0.1:6006 -N Administrator@192.168.0.3

See, it adds -T and -N. This suppresses the command window somewhat.
It prevents the bash shell from being spawned. You don`t need it. You
just want to secure VNC

You could try the OpenSSH client. instead of putty. (it has can be
installed in cygwin, or a version exists as "a windows port")
What SSH server are you using?
OpenSSH has a client and a server. If you are using the OpenSSH
server , then may as well use the client.

It sounds a bit like an OS error you are getting. Like with windows
xp. Have a look in event viewer. See if any errors occur at the time
of the crashes. Make it crash and check straight after what errors
there are if any.



If in windows.

Thank you for your patience
