Aug 08, 2015 · These ports were open by default: TCP: 139; 135; 445; The TCP port 135 is used by the Microsoft Windows RPC service, this service is also known by the process name MSRPC. The TCP port 139 and 445 are identified as ports which are used by the netbios-ssn service. In NBT, the session service runs on TCP port 139. The session service primitives offered by NetBIOS are: Call – opens a session to a remote NetBIOS name. Listen – listen for attempts to open a session to a NetBIOS name. Hang Up – close a session. Send – sends a packet to the computer on the other end of a session. For example, regular web traffic uses port 80, while the POP3 email uses port 110. One of the ways that a firewall works is by allowing or restricting traffic over a particular port. Because the port configuration can cause a security risk, it’s critical to know which ports are open and which are blocked.
