How to Check Allowed Connections to the Server?

Understanding which connections to the server are allowed is an important aspect for all webmasters and site owners. Whether you are a novice developer or an experienced specialist, knowing how to check allowed connections will help you ensure the security and stability of your site.

There are several ways to check allowed connections to the server. Here are some of them:

  • netstat: The netstat command, available in the command line, allows you to view active connections to your server. You can use this command to find out which ports are open for connections and which IP addresses are active.
  • lsof: Another useful command for checking allowed connections is lsof. It allows you to view open files and connections on your server, which will help you identify potential security problems and optimize server performance.
  • firewall: Don’t forget to check your firewall configuration. Make sure that only the necessary ports are open, and all unnecessary connections are blocked. This is rightly considered a best practice for ensuring server security.
  • access to server logs: Don’t forget to check your server logs regularly. In the logs, you can see a list of all active connections, anomalies, and potential security threats. This will give you an idea of which connections are actually allowed and need your attention.

The presented methods will help you effectively check the allowed connections to your server. Remember that the security and stability of your site depend on carefully checking connections and regularly monitoring activity on the server.
