Port Number 366 | What is Port 366?

Information about tcp/udp Port 366

A Software Port (usually just called a 'port') is a virtual data connection that can be used by programs to exchange data directly, instead of going through a file or other temporary storage location. The most common of these are TCP and UDP ports which are used to exchange data between computers on the Internet. Port 366 uses the tcp/udp protocol for service type odmr. A malformed request to port 366 is known to cause denial of service attacks.

In the TCP and UDP protocols used in computer networking, a port is a special number present in the header of a data packet. Ports are typically used to map data to a particular process running on a computer. Port numbers can occasionally be seen in the URLs of websites. By default, HTTP uses port 80 and HTTPS uses port 443, but a URL like would try to connect to an HTTP server on port 8000 instead. Port 366 is used for the odmr service. An example would be when accessed by a web service. Port 366 may be used for several services including ODMR-- and more. Port 366 is known to have vulnerabilities caused by trojans and remote code execution.

Note that not all transport layers use network ports; for example, although UDP and TCP use ports, ICMP does not. By default, the firewall should disallow traffic to port 366 until all security checks have been passed. If an application cannot listen on port 366, the port 366 is already in use by another application causing the conflict.

Port 366 Information

  • Go to the command prompt (Start>Run>cmd)
  • Enter netstat -ano
  • You will get a report of Active Connections
  • Report includes: Protocol, Local Address, Foreign Address, State, PID
  • e.g.
    • Proto Local Address Foreign Address State PID
    • UDP *:* 366
  • Write down the PID (process identifier) associated with port 366 (Also note the Local Address, Foreign Address, Protocol and State.)
  • Next, start the Windows Task Manager
  • Select the Processes tab in Task Manager
  • Search for the PID you wrote down previously
  • netstat parameter -s displays per-protocol statistics. By default, statistics are shown for IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and UDPv6

How to manually open Port 366 in Windows Firewall?

Windows Firewall may block port 366 by default. If you want to allow a program to communicate using Port 366 through the firewall, you can usually do that by selecting the required program on the Exceptions tab in Windows Firewall. However, sometimes the program is not listed in the Exceptions tab. In this case you need to open the port manually.

1.Open Windows Firewall by clicking Start, Control Panel, Security, and then Windows Firewall.

2.Click 'Allow a program through Windows Firewall'.

3.Click 'Add port'.

4.In the 'Name' field, type a friendly name for the port like 'Port-366'.

5.In the 'Port number' field, enter the port number '366'.

6.Select TCP or UDP, depending on the protocol required for port 366.

How to scan a PC/network for tcp/udp port 366 vulnerabilities?
If you detect unusual port 366 activity or port 366 intrusion, you need to check for known security risks. Security risks are due to remote hacking attempts, trojans, malware and spyware present on the computer. Incorrect port 366 mapping, port 366 forwarding, or port 366 binding can cause vulnerabilities as well. A port scanner or network analyzer will detect open 366 ports used on a PC (or a network) and detect security threats. Other software tools like an IP scanner, open port 366 scanner, remote open port 366 scanner, open port scan tool or remote port check can be used. The software below is free or open source.
