Unidirectional sniffing: Victim to Gateway

ettercap -T -M arp:oneway,remote /1.2.3.4/ /1.2.0.0/

This is what the command line options do:

using nmap to scan port

scan sql

nmap -f -sS -v -A -p3306 202.185.x-x

scan web

nmap -f -sS -v -oA dvwa -A -p 80,443 202.185.x.x-x

some tips to improve ssh server

get from http://askubuntu.com/questions/2271/how-to-harden-an-ssh-server

Here's one easy thing to do: install ufw (the "uncomplicated firewall") and use it to rate limit incoming connections.

From a command prompt, type:

$ sudo ufw limit OpenSSH 

If ufw is not installed, do this and try again:

$ sudo aptitude install ufw 

Many attackers will try to use your SSH server to brute-force passwords. This will only allow 6 connections every 30 seconds from the same IP address.
