Such network reconnaissance should be completed regularly to identify and remediate vulnerabilities before they're discovered by cyberattackers. It involves identifying open ports and also sending data packets to select ports on a host to identify any vulnerabilities in received data. Therefore, if you don’t want to clutter your Mac with additional software, Terminal is an effective solution.Port scanning is the process of analyzing the security of all ports in a network. While port scan in Terminal isn’t as clean and intuitive as the tool in the deprecated app, you can replicate its functions well with the right commands.Īs you can see, we’ve managed to reproduce all of Network Utility’s primary features. The command works similarly to the old Network Utility feature. On top of that, finger is still a useful tool for requesting information about users on your network. Whois works similarly in Terminal, and entering the command with a target domain name provides detailed information about the owner of the property. Using a domain name performs a standard lookup, and inputting an IP address does the reverse. With the right command, you can also replicate the Lookup tool in Terminal. In addition, ping as a Terminal command performs the same operations as the Network Utility tool, which means, once again, you haven’t lost any functionality here. The netstat command provides detailed information about your network that mimics the old app’s functionality, so you’re not missing anything with the loss of this feature.
