Security Basics: Re: problem with nmap options

[Jacob Bresciani <jacob () bresciani ca>]

curious what the first -o option is for? nmap on my system doesn't  
list it as an option.
What OS is this on?

On my OSX 10.4 laptop I ran the command

sudo  nmap -p21,135,136,137,138,80,23,25  192.168.0.0/24 -oG /tmp/ 
ips.txt -sF
then checking /tmp/ips.txt it contains sections like

Host: 192.168.0.232 ()  Ports: 21/closed/tcp//ftp///, 23/closed/tcp// 
telnet///, 25/closed/tcp//smtp///, 80/closed/tcp//http///, 135/closed/ 
tcp//msrpc///, 136/closed/tcp//profile///, 137/closed/tcp//netbios- 
ns///, 138/closed/tcp//netbios-dgm///
was this the output you where looking for?
