[erlang-questions] Erlang and Cowboy network problem

[Yvan Godin]

Hello Erlang list,

I need some helps, I am trying to make *Cowboy* working in Virtual machine
on *ERLANG R16B* but

If I configure *Cowboy* without IP binding it work but only on localhost
(no external acces)

as root, if I bind an IP it work only on PORT 80 and not for other port
(tryed 8000 8080 etc..)

Cowboy parameters (trying demo web_server with IP ,no IP, and different
ports)
        {ok, _} = cowboy:start_http(http, 100, [{ip,{0,0,0,0}},{port,
8088}],

run with :    erl -pa ebin deps/*/ebin -s web_server -smp disable  (only
one core / smp or not doesn't change thing)

Is there a known problem with Erlang R16B on Virtual machine ? A binding
problem on virtual net ? a cowboy problem ? A mistake from myself ?


below some parameters

If you have any clues, thank's for your help
Best regards,
Yvan


(the VPS used  http://www.lws.fr/serveur_dedie_virtuel.php)

The machine has been reintalled on UBUNTU 12.10 and Erlang R16B. But  was
previously working with DEBIAN 6 and NITROGEN on Erlang R15B over Cowboy
