Subject: explanation of ports
In easys words: a listener process waits for incoming connections
on ALL ports and try to find a process what is defined to wait for
the requested port. If that port specific process exist, it will get the
connection from them listener process an handle the connection.
Port 135 through 139 handle NBT (Netbiso over TCP/IP)
connections under Microsoft Windows.
Is that you want to know?
