A Linux administrator implemented a new HTTP server using the default configuration. None of the users on the network can access the server. If there is no problem on the network or with the users'…

Running `netstat -tulnp` (or `ss`) is crucial to confirm that the HTTP server process is actively listening on the standard HTTP port (typically 80 or 443) and is correctly bound to an IP address. If the server is listening, the next common culprit for inaccessibility is a firewall blocking incoming connections, so configuring the firewall to allow access on the relevant ports (e.g., 80 for HTTP) is the necessary resolution.

The `route` command displays or modifies the IP routing table, which is not used to check if a port is bound or for basic firewall configuration.

`netcat` is a versatile networking utility for reading and writing data across network connections, but `netstat` is more appropriate for checking listening ports, and configuring a static route is irrelevant for making a local web server accessible from the network.

While `SELinux` can block access, checking `netstat` for port binding is a more fundamental first step than `route`, and the question implies a default configuration issue that would more commonly involve the firewall before `SELinux` context if the server isn't even binding.
