Find out if a host/network is protected by a firewall using namp command # nmap command examples for your host # Turn on OS and version detection scanning script (IPv4) with nmap nmap -A 192.168.1.254 OR exclude list from a file called /tmp/exclude.txt nmap -iL /tmp/scanlist.txt -excludefile /tmp/exclude.txt 5. When scanning a large number of hosts/networks you can exclude hosts from a scan: nmap 192.168.1.0/24 -exclude 192.168.1.5 Excluding hosts/networks (IPv4) from nmap scan examples The syntax is as follows: nmap -iL /tmp/test.txt 4. Create a text file as follows:Īppend names as follows: This is useful to scan a large number of hosts/networks. The -iL option allows you to read the list of target systems using a text file. Read list of hosts/networks from a file (IPv4) You can scan a range of IP address using a wildcard: nmap 192.168.1.*įinally, you scan an entire subnet: nmap 192.168.1.0/24 3. You can scan a range of IP address too: nmap 192.168.1.1-20 Scan a single host or an IP address (IPv4) using nmapįig.01: nmap output 2.

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. 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. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap (“Network Mapper”) is an open source tool for network exploration and security auditing.
