Hi, I am using Nmap version 3.00 to do a ping sweep of a network on Enterprise Redhat Linux 2.4.21-27. Thh command line I use is "nmap -sP 192.168.1.1/24 " When I am running the ping sweep as normal user I am able to discover some devices in the network. But when I run the ping sweep as root user it is detecting more devices and in some cases reporting non existing host as running. Anyone hit this issue before ?
- From $ man nmap : Significant effort has been put into decent nmap performance for non-root users. Unfortunately, many critical kernel interfaces (such as raw sockets) require root privileges. nmap should be run as root whenever possible (not setuid root, of course). So yes, it's normal to get more and better results if you're running nmap as root. Marcos Marado- -- /* *********************************************************** */
