i added the html file "websoket.html"
in /var/www/esr/websoket.html

and i loaded it with :


http://my.hos.edu/esr/websoket.html


i received this in the browser ..:


WebSocket Test

CONNECTED

SENT: WebSocket rocks

RESPONSE: WebSocket rocks

DISCONNECTED


so i guess it worked.

- tring to load the 

/my.hos.edu:8888   


without VPN is not working

the ipython std out is clean .. no traceback/errors there. 

should i set dome option in the notebook, to increase the debug-level to have it "more verbose"


p.s.

i'm online on IRC.freenode
