Nmap done: 1 IP address (1 host up) scanned in 0.03 seconds Warning: You are not root - using TCP pingscan rather than ICMP
After making an attempt to contact an IP address (either using Nmap or some other tool like ping), run arp -n to print the table of IP-to-MAC address mappings. Fortunately, there are other sources of MAC address information on a Linux system: the systems ARP tables. I added the results from my own systems with and without -privileged below: $ nmap -sP -PE 192.168.0.1 Nmap must be run as root in order to retrieve this information. Or as an environmental variable: export NMAP_PRIVILEGED=""Įdit: I don't exactly know why this answer is being down-voted since this is one possible answer to the question (although the question is of course better suited for Super User or Unix & Linux Stack Exchange). You can define it as an argument of nmap nmap -privileged -sP -PE -iL But, you have to explicitly define that you want to do so. Finally, you are able to run nmap as unprivileged user. sudo setcap cap_net_raw,cap_net_admin,cap_net_bind_service+eip /usr/bin/nmapĤ. Once again, make sure to use the right location.

Make sure the setcap command is installed ( more information about capabilities here): sudo yum install libcapģ. In my case, this was /usr/bin/nmap: sudo chgrp adm /usr/bin/nmapĢ. Make sure that you use the right location of nmap. Restrict access to certain groups, for example adm. If you do not understand these risks, do not do this.ġ.

It's possible, especially with elevated capabilities, for a clever person to use Nmap and NSE to escalate to full root privileges. The Nmap Scripting Engine (NSE) allows scripts to sniff the network, change firewall roules and interface configuration, or exploit vulnerabilities including on localhost. I think it is important to keep this security warning in mind:
It should be the first choice for every network. It is easy to use and runs as a portable edition. The program shows all network devices, gives you access to shared folders, provides remote control of computers (via RDP and Radmin), and can even remotely switch computers off. The linked tutorial also describes this for Ubuntu and Red Hat systems, which should be good for you since you are on CentOS. Reliable and free network scanner to analyse LAN.

This Wiki describes pretty good how to set everything up to run it as an unprivileged user. It is possible to run nmap as non-root user.
