What is 3688 port in TCP/IP?

The bad translation will be seen.

A software port (usually just called a "port") is a virtual data connection that can be used to exchange data directly, rather than through files or other temporary storage locations. The most common of these are TCP and UDP ports, which are used to exchange data between computers on the Internet. The 3688/UDP port uses a simple push-s-s simple push protocol for service types. A malformed request port 3688/udp is known to cause a denial of service attack.

The TCP and UDP protocols used in computer networks, the port is a special number that is currently in the head of a packet. Ports are typically used in the process of data mapping to a specific computer running. The port number can occasionally be seen on the website URL. By default, HTTP uses port 80,https with port 443, but a Web site like Http://www.MyCompany.com:8000/tries to connect to Port 8000 of an HTTP server. The 3688/UDP port is used for pushing simple services. An example is http://www.MyCompany.com:3688/udp/when a Web service is accessed. 3688/UDP ports can be used for a variety of services, including simple push security and more. The 3688/UDP port is a vulnerability caused by known Trojans and Remote code execution.

Note that not all transport layers use the network port, for example, although UDP and TCP use ports, ICMP does not. Firewall by default, port 3688/UDP should be blocked until all security checks have passed. If an application can not listen to the 3688/UDP port, the port 3688/UDP has already been used in another application that is causing the conflict.

Go to the command prompt (Start>run>cmd)

Enter Netstat-ano

You'll get a on Active connections

Foreign address, state, PID, Includes:protocol

e.g.

Proto Local address Foreign address State PID

UDP 127.0.0.1:3688/UDP *:* 3688/udp

Write down the PID (process identifier) associated with Port 3688/udp (Also), Foreign address, Proto Col and state.)

Next, start the Windows Task Manager

Select The Processes tab in Task Manager

Search for the PID your 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 do I manually turn on the 3688 port/udp in Windows Firewall?

Windows Firewall may blocks port 3688/udp by default. If you are want to allow a and communicate using Port 3688/UDP through the firewall, you can usually do this by selecti NG the required program on the Exceptions tab in Windows Firewall. However, sometimes the program isn't listed in the Exceptions tab. In this case you are 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-3688/udp '.

5.In the ' Port number ' field, enter the port number ' 3688/udp '.

6.Select TCP or UDP, depending on the protocol required for Port 3688/UDP.
