Who s going to give me a list of port services, okay?

For example, Oracle Database Service (Database) is open when Oracle is running normally. Let's say the IP of that server is. You can run a command line window in the Windows environment and type "telnet 1521" to check whether port 1521 is enabled.

After entering, if no information is displayed in the command line window, port 1521 is open.

If port 1521 is down, the command line window will show that the connection failed

If it says "Not an internal or external command", you need to set it in Programs and Functions. Select "Programs and Features" in the Control Panel, and select "Turn Windows Features on or Off" in the "Programs and Features" interface.

In the Windows Functions dialog box that appears, select the Telnet server and Telnet client and save the settings. After the setting is complete, you need to re-open a command line window to run the telnet command, and the command window opened before the setting is invalid to run telnet.

If the server is connected to the Internet through a route, pay attention to a port map on the route.

Use the telnet ip address port number command under the window server, you can try it. Hope it helps.

Run the netstat command to check the status of the port listener.

2. It is unimaginable for the server to achieve so many functions without comprehensive software support. However, if there are too many software systems, the performance of the server may be reduced, and the management personnel cannot effectively control it.

3. Therefore, many server manufacturers must make great efforts in the ease of use of the server in addition to the availability and stability of the server when designing the server.

1. Not only should the firewall installed by yourself be lowered or turned off, but also the firewall with the XP system should be turned off.

2. Check whether the service is opened correctly and whether the port is occupied.

3. Whether the IP address is on the Internet.

4. flashfxp Chinese version: Options--Parameter Selection--** Firewall Identity--Remove the checkbox before "Use passive mode".

If it still can't be resolved, please send the server information to my email to solve the problem.
