Fix Local FTP Server Access on Linux

If you are unable to access the FTP server locally, it may be due to firewall settings or network configuration issues. Here are some solutions:

1. Check the firewall settings to ensure that the firewall allows the FTP service port to pass through. FTP typically uses port 21, so if the firewall has restrictions, you can try disabling or modifying the firewall rules.
2. Check the FTP server setup: make sure the FTP server is properly configured, including user permissions, file directories, and other settings. You can examine the FTP server’s log files to see if there are any error messages.
3. Check network configuration: Make sure that the local network settings are correct and can access the IP address of the FTP server. You can try using an FTP client to connect to other FTP servers for testing to confirm that the network is functioning properly.
4. Check the status of the FTP server: Make sure the FTP server has been properly started and is running. You can confirm if it is running correctly by checking the process status or log files of the FTP server.

If the above methods are unsuccessful in resolving the issue, try restarting the FTP server or computer to attempt a solution. If the problem persists, it is recommended to consult the official documentation of the FTP server or seek help on relevant technical forums.
