nmap -e fx0 -v -sP 192.168.128.0/23 -> is a "Ping Scan however, and this does not require root privilages... -sP (Ping Scan) -v (Increase verbosity level) -e <iface>: Use specified interface=20 Error: > getinterfaces: Failed to open ethernet interface (el0) QUITTING! Which seems to indicate that nmap is being told to look for an interface that can't/doesn't exist... el is an old 3Com ISA card You mentioned using ethernet device "fx0" - did you mean "fxp0", the Intel Intel EtherExpress Pro/100 style cards? ...or you may have already discovered this ;) It might be worth checking exactly what interfaces and hardware you do have on this system... ...and you could also try running the command without specifying the interface directly and rely on the routing table to sort it out. Nmap does not require the "-e" flag to run a "Ping Scan". nmap -v -sP 192.168.128.0/23 Hope this helps!

Are you running nmap as root? If not, you should.
