Port 30005 Details
known port assignments and vulnerabilities
4 records found
||Port sometimes associated with TR-069 - application layer protocol for remote management of end-user devices. It is a bidirectional SOAP/HTTP-based protocol that provides communication between CPE devices and auto-configuration servers (ACS). It can be used by some modems, gateways, routers, VoIP phones, set-top boxes. TR-069 has some known exploits as demonstrated at the DEFCON22 conference. Cox Communcations reportedly uses this port.
If your modem/NAT router/gateway keeps this port open and you are sure you want to filter it (potential interference with ISPs pushing firmware updates), try the following. Navigate to your router's admin interface and disable TR-069. If that does not work, look under "port forwarding", or "virtual servers", and forward port 30005 to an unused local IP address, like (192.168.1.252)

TCP ports use the Transmission Control Protocol. TCP is the most commonly used protocol
on the Internet and any TCP/IP network. Whereas the IP protocol deals only with packets, TCP enables two hosts
to establish a connection and exchange streams of data. TCP guarantees delivery of data
and that packets will be delivered in the same order in which they were sent.
Guaranteed communication/delivery is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol, a communications protocol for the Internet network,
transport, and session layers. Like TCP (Transmission Control Protocol),
UDP is used with IP (the Internet Protocol) and makes possible the transmission of datagrams
from one computer to applications on another computer, but unlike TCP, UDP is connectionless
and does not guarantee reliable communication; it's up to the application that received
the message to process any errors and verify correct delivery. UDP is often used with time-sensitive
applications, such as audio/video streaming, where dropping some packets is preferable to waiting for delayed data.
When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them.
This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command.
We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software.
