Some more testing and tracing has led me to the place of the error, but I still
don't know why.

prim_inet.erl:
open1(Type, Family) ->
    case open0(Type) of
	{ok, S} ->
	    case ctl_cmd(S,?INET_REQ_OPEN,[Family]) of
		{ok, _} -> {ok,S};
		Error -> close(S), Error
	    end;
	Error -> Error
    end.

or from the shell

#Port<0.36>

[0,101,105,110,118,97,108]

The funny thing is that I can set up a tcp connection from the windows
machine to
the linux machine. But not from the windows machine to the internet.

Any ideas anyone????
