root@FSASRVPROXY:~# nmap -sT -O localhost Starting Nmap 6.47 ( http://nmap.org ) at 2016-04-07 15:49 BRT pcap_open_live(lo, 8192, 0, 200) FAILED. Reported error: lo: That device is not up. Will wait 5 seconds then retry. pcap_open_live(lo, 8192, 0, 200) FAILED. Reported error: lo: That device is not up. Will wait 25 seconds then retry. Call to pcap_open_live() failed three times. There are several possible reasons for this, depending on your operating system: LINUX: If you are getting Socket type not supported, try modprobe af_packet or recompile your kernel with PACKET enabled. *BSD: If you are getting device not configured, you need to recompile your kernel with Berkeley Packet Filter support. If you are getting No such file or directory, try creating the device (eg cd /dev; MAKEDEV <device>; or use mknod). *WINDOWS: Nmap only supports ethernet interfaces on Windows for most operations because Microsoft disabled raw sockets as of Windows XP SP2. Depending on the reason for this error, it is possible that the --unprivileged command-line argument will help. SOLARIS: If you are trying to scan localhost or the address of an interface and are getting '/dev/lo0: No such file or directory' or 'lo0: No DLPI device found', complain to Sun. I don't think Solaris can support advanced localhost scans. You can probably use "-Pn -sT localhost" though. QUITTING!

seguinte, o firewall só serve para controlar o acesso a serviços de rede, o serviço de rede é quem é responsável pela porta em si, um exemplo: o serviço de acesso remoto ssh, que roda por padrão na porta 22, se vc parar esse serviço, mesmo sem regra nem uma de firewall aplicada e tentar usar o nmap, a porta 22 não sera mostrada, pq não existe serviço rodando nessa porta, deu pra intender?Criar entrada (menuentry) ISO no Grub
