socket programming

Hi

I am newbi in socket programming. I am learning it
with SWI for the simplicity and quick results.
I tried some socket SWI's socket predicates,
during that I met a problem.

I opened two seperate prolog tasks.
Following small codes shows what I wrote in
each task stepwise.
*Note*: 'advait' is my hostname i.e. my compueter itself

%%%%%%%%%%%%% Task 1 %%%%%%%%%%%%%%%%%%%%%%%%%

?- tcp_socket(Sock),tcp_bind(Sock,P). %% Step 1

Sock = '$socket'(252)
P = 1032


?- tcp_socket(Sk),tcp_connect(Sk, raut:1033). %% step 3

ERROR: Socket error: Connection refused
Exception: (17) socket:tcp_connect('$socket'(256), advait:1033) ?
creep


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%



%%%%%%%%%%%%%%%% Task 2 %%%%%%%%%%%%%%%%%%%%%

?- tcp_socket(Sock),tcp_bind(Sock,P). %% Step 2

Sock = '$socket'(252)
P = 1033


?- tcp_socket(Sk),tcp_connect(Sk, advait:1032). %% Step 4 immediately
%% after step 3

ERROR: Socket error: Connection refused
Exception: (8) socket:tcp_connect('$socket'(256), advait:1032) ?
creep

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Why did I get these errors in each of the tasks?
Please, Can anyone help me ?

yours
Advait
