It is. Check and thanks!

This is convincing. Only, I don't get any display. Maybe somthing wrong
to be pointed out easily?
1. I start vncviewer -listen 1 on ws_at_home.
It tells me it's listening on port 5501
2. I start vncserver on ws_at_work.  
It tells me "New 'X' desktop is ws_at_work:1
3. I start the link on ws_at_work with 
ssh -2 -N -L 5501:localhost:5501 ws_at_home.
It asks for password and accepts (though no confirmation, just nothing.
But if I give the wrong one, it complains. Seems to be okay.)
4. I connect on ws_at_work using vncconnect -display :1 localhost:1
It returns the prompt on the next line and fails to connect (without an
error message on either side; simply no changes).
Yes, everything under root.

Thanks for any hint,

Uwe
