# Lab Setup To learn about Nmap, we need to set up a lab environment. You can use vulnerable machines like **Metasploitable2**, **Metasploitable3**, other **VulnHub** virtual machines, or even your own custom-built targets. However, setting these up can be time-consuming. To save time, we'll be using the [**TryHackMe: Further Nmap**](https://tryhackme.com/room/furthernmap) room. This room is specifically designed to teach Nmap. If you're following along with our handbook, you can skip the content in the room itself—just start the machine and connect to the TryHackMe VPN using **OpenVPN** to access the target IP. Once you're connected and able to **ping the machine's IP**, you're ready to continue. If you're unfamiliar with how to connect to TryHackMe’s network, refer to this room: [**TryHackMe: OpenVPN**](https://tryhackme.com/room/openvpn). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://handbook.ncateam.xyz/reconnaissance/network-enumeration/lab-setup.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
