Thanks Tim: well, the real interface is rl0...:) sorry for the confusion. the problem is that the nmap seems to have mind of its own and stick with em0: sis# nmap -e rl0 -v -sP 192.168.126.0/23 Starting Nmap 3.95 ( http://www.insecure.org/nmap/ ) at 2006-02-08 12:01 CST getinterfaces: Failed to open ethernet interface (em0) QUITTING! It has 4 interfacres but nmap just sticks with em0. i am lost ...
