Hello! I know that the nmdb daemon uses ports 137 and 138 to listen and respond to name queries, but I was looking for what these specific ports do. What's the difference betweeen port 137 and 138? I tried googling for it but found nothing and the man page only mentions port 137. Thank you! -- Diego Lima http://www.diegolima.org
Entering "port 138" on Google immediately gave me the following: Port 138 Name: netbios-dgm Purpose: NETBIOS Datagram Service Description: UDP NetBIOS datagrams packets are exchanged over this port, usually with Windows machines but also with any other system running Samba (SMB). These UDP NetBIOS datagrams support non-connection oriented file sharing activities. Related Ports: 137, 139, 445 Try it for yourself. It works and you will get plenty of information :-)
