However, now, when I type 'nmap 192.168.1.10', (where > 192.168.1.10 is the PC that I wanted to scan) ... I got the message ... > > 'Limiting closed port RST response from 283 to 200 packets/sec' This is not a message from nmap, but from FreeBSD. It means that the system is sending more than 200 ICMP packets/per second. I reckon you see this line on the machine you're scanning. Your scan will continue as normal but will be slowed down by this cool safety feature of FreeBSD :). If you want to turn this off set sysctl net.inet.icmp.icmplim_output=0. Please keep in mind that a scan will take a long time to complete with nmap's default options. Hope this helps, Pieter
