Hy !!!
Typing netstat -ano, I get this :

 TCP    127.0.0.1:1210         127.0.0.1:1211         ESTABLISHED     2572
 TCP    127.0.0.1:1211         127.0.0.1:1210         ESTABLISHED     2572

I want to understand why pid 2572 (firefox) stay listening on the lopback address port 1210
for connection coming from lopback address port 1211, and vice versa. What this mean?
Thanks for yours helps
