Question 6: How to open the computer port? Each service corresponds to a corresponding port. For example, as we all know, the port of WWW service is 80, TP is 25 and ftp is 2 1. These services are all started by default in win2000 installation. Individual users are really unnecessary. Closing a port means closing useless services. In the control panel "Administrative Tools" in "Services".
1, close ports such as 7.9: close simple TCP/IP services and support the following TCP/IP services: character generator, daytime, discard, echo and quotation of the day.
2. Close port 80: Close the WWW service. The name displayed in "Service" is World Wide Web Publishing Service, which provides web connection and management through the snap-in of Internet information services.
3. Close port 25: Close the Simple Mail Transfer Protocol (SMTP) service, which provides the function of sending e-mail across the network.
4. Close port 2 1: Close the FTP publishing service and provide FTP connection and management through the Internet information service management unit.
5. Close port 23: Close the Telnet service, which allows remote users to log on to the system and run console programs using the command line.
6. It is also important to shut down the server services that provide RPC support, files, printing and naming pipes. Turning it off will turn off win2k's default * * * enjoyment, such as ipc$, c$, admin$ and so on. The shutdown of this service will not affect your other operations.
7. The other port is 139, which is a NetBIOS session port for file and print * * *. Note that the unix machine running samba has also opened the 139 port, which has the same function. In the past, streamer 2000 was not very accurate in judging the host type of the other party. It is estimated that the 139 port is open, and it is considered to be an NT machine, but it is ok now. The way to turn off 139 listening is to select the Internet Protocol (TCP/IP) attribute in the LAN connection in the network and dial-up connection, enter the advanced TCP/IP settings and WINS settings, and there is an item "Disable NETBIOS of TCP/IP", and then tick off the 139 port. For individual users, it can be set to "Disabled" in various service attribute settings to avoid restarting the service and opening the port next time.

Question How does win7 open the port 1? First select the start menu to enter the control panel, and then select windows Firewall.
2. Then select the Advanced Settings option.
3. Select the inbound rule.
4. Create a new rule
5. Select a port and click Next.
6. As shown in the figure, enter the port to be opened, such as 3333, and click Next.
7. Next step
8. Next step
9. It is best to write down the name of the open port so that you can find it next time and click Finish.
10. At this point, it has been displayed in the inbound rules, indicating that it has succeeded.
Question 8: [Network Configuration] How to check your own port number? You need to fill in the port when setting up the proxy server. This port number can be freely filled in on the server side, generally greater than 1024 and less than 65535. When the client uses the proxy server to surf the Internet, the port number must be the same as the port number set by itself on the proxy server.
Tomcat uses port 8080 by default, which can be changed by itself.
Generally, the port number of server-side software can be customized, as long as it is between 1024-65535, and it is not repeated. Each software sets the port number in a different way. Usually in the "Settings" interface.
If the client software wants to set the port number, it must be the same as the server software.
Question 9: How to check the open network port of this machine? Click "Start → Run" in turn, enter "cmd" and press enter to open the command prompt window. Type "netstat -a -n" at the command prompt, and then press Enter to view the port number and status of TCP and UDP connections displayed in digital form.
Network statistics-electronics -n -o -s-an
-a displays all active TCP connections and TCP and UDP ports that the computer listens to.
-e indicates the number of bytes and packets sent and received by Ethernet.
-n indicates that only the addresses and port numbers of all active TCP connections are displayed in digital form.
-o displays the active TCP connections, including the process ID(PID) of each connection.
