Using the following manual page for a program, write a command to perform a port scan on 192.168.1.1 that enumerates the operating system:

Name
nmap - Network exploration tool and security / port scanner

Synopsis
nmap [Scan Type...] [Options] {target specification}

Description
Nmap ("Network Mapper") is an open source tool for network exploration and security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. While Nmap is commonly used for security audits, many systems and network administrators find it useful for routine tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.

The output from Nmap is a list of scanned targets, with supplemental information on each depending on the options used. Key among that information is the "interesting ports table".. That table lists the port number and protocol, service name, and state. The state is either open, filtered, closed, or unfiltered. Open. means that an application on the target machine is listening for connections/packets on that port. Filtered. means that a firewall, filter, or other network obstacle is blocking the port so that Nmap cannot tell wh
