Nmap done: 1 IP address (1 host up) scanned in 0.03 seconds Warning: You are not root - using TCP pingscan rather than ICMP I added the results from my own systems with and without -privileged below: $ nmap -sP -PE 192.168.0.1 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.

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: The linked tutorial also describes this for Ubuntu and Red Hat systems, which should be good for you since you are on CentOS.
