TCP 6699
Synopsis
- TCP port 6699 is historically associated with the Napster/OpenNap file-sharing protocol.
- OpenNap server software such as SlavaNap typically listens on TCP 6699.
- WinMX, a popular P2P client, uses TCP 6699 by default for incoming connections and file transfers (with UDP 6257 alongside).
- Many network device and IDS signatures label 6699/tcp as Napster/WinMX traffic due to these deployments.
