Nmap has much more to offer than what we mention above, you can see the full list of possible commands and flags by typing: The вЂ“traceroute flag incorporates the familiar trace route ability in the scan, note this has to be run as root through sudo:

In this example, if is live through the alternate DNS but not available to you without specifying вЂ“dns-servers, you may have an issue with whichever DNS servers you are using rather than the host itself. Here weвЂ™ll use nmap to scan through alternate DNS (GoogleвЂ™s DNS servers used in example) of : The вЂ“dns-servers flag overrides system DNS settings for that scan.

By using the вЂ“traceroute and вЂ“dns-servers flags youвЂ™ll be able to help determine whatвЂ™s going on and where, and the latter is particularly helpful if you are having trouble accessing certain remote IPвЂ™s but are unsure if the host is actually unavailable or if your DNS servers are the issue. Nmap is also really useful for troubleshooting internet connections, WAN issues, and publicly available assets, and it can be helpful when trying to figure out if a network issue is your network, an ISP, or somewhere else along the way. Nmap -osscan-guess 192.168.0.2 Using Nmap with Alternate DNS Servers & Trace Route If nothing is reported back (not uncommon), you can try to use the вЂ“osscan-guess flag instead to try and guess which OS is running based on the services detected: This does not always work, but thereвЂ™s no harm in trying: Using the same IP range concept as above, you can attempt to discover which operating systems and their accompanying versions are running on the networked machines. Nmap 192.168.0.* Scan & Detect Operating Systems If you donвЂ™t know the range, you can also use wildcards: WeвЂ™ll assume your LAN has an IP range of 192.168.0.1 to 192.168.0.25, change those numbers as appropriate: You can also find information about other machines on your local network. Scan & List a Range of Local Network IPвЂ™s Separately, if you started a local web server at some point (even the super quick python http server), youвЂ™ll also find those running. This letвЂ™s you know that SSH/SFTP, HTTP, Samba, and the Apple File Sharing protocol are all open on the localhost Mac, and shows which ports theyвЂ™re running under.ДЇor a Mac, toggling various options directly in the System Preference вЂњSharingвЂќ panel will directly impact what you see as running, whether itвЂ™s to activate the SSH and SFTP server and enabling remote login, turning on and off file sharing for Macs or Windows or both, screen sharing, or whatever else. You might see something like the following reported back: Nmap makes it very easy to find out which ports are open on localhost (that is, your computer):

On the other hand, scanning a Windows PC or a network of Windows machines will often give you a huge amount of information and reveal many services, even if the Windows firewall is enabled.

Do note that its not unusual for very little information to be reported back from Mac OS X machines, particularly if the software firewall has been enabled and no sharing services are enabled. Nmap works with both LAN and WAN IPвЂ™s and has near infinite applications, but weвЂ™ll cover a few commonly used simple tricks. ThereвЂ™s no need to reboot, but you will want to refresh or open a new Terminal to have nmap found in your path.

Install the full nmap suite, or selectively choose whether to install ncat, ndiff, nping, etcДЇor installing Nmap on Mac with Homebrew, just run the following command:.

Install through the dmg, be sure to right-click and choose вЂњOpenвЂќ to get around the Gatekeeper warning if itвЂ™s still enabled.

To download the the dmg installer for nmap via : Using the DMG installer is the easiest way, but you can also build nmap yourself from source or get it through something like Homebrew or MacPorts. These are all useful tools as well, so itвЂ™s a good idea to install them all along the way. While installing nmap you will also have the option to install the full suite of network discovery utilities, including ncat, zenmap (requires X11), ndiff, and nping.
