This article will combine the hot content of the entire network in the past 10 days, introduce in detail how to open the server port, and provide structured data for reference.
1. Review of recent hot technology topics
The following are hot topics in the technology field in the past 10 days, with discussions related to server configuration being particularly prominent:
| Ranking | topic | heat index |
|---|---|---|
| 1 | Server security port configuration | 95 |
| 2 | Cloud server firewall settings | 88 |
| 3 | Linux vs Windows port management | 82 |
| 4 | Recommended port scanning tools | 76 |
| 5 | Docker container port mapping | 70 |
2. Detailed explanation of the steps to open the server port
Opening server ports usually involves operating system configuration and firewall settings. The following is the operation process of common systems:
| System type | Operation steps | Common commands |
|---|---|---|
| Linux | 1. Modify iptables or firewalld rules 2. Save the configuration and restart the service | firewall-cmd --add-port=8080/tcp iptables -A INPUT -p tcp --dport 8080 -j ACCEPT |
| Windows | 1. Open the firewall settings through the control panel 2. Add inbound rules | netsh advfirewall firewall add rule name="Open Port 8080" dir=in action=allow protocol=TCP localport=8080 |
| cloud server | 1. Configure security group rules on the console 2. Bind instance IP | (The interface operations of each platform are different) |
3. Port configuration considerations
1.security risk: Opening ports may increase the probability of being attacked. It is recommended to use it in conjunction with IP whitelisting.
2.Port conflict: Avoid using known service default ports (such as 80, 443).
3.Log monitoring: After opening the port, you need to check the access log regularly.
4.temporary test: You can use the nc or telnet command to quickly verify whether the port is open.
