Unidirectional sniffing: Victim to Gateway
A more sensible and stealthy command is:

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.

Ubuntu local apt repositories (intranet)

know the difficulty of achieving common package if want to try to install new applications in ubuntu for PC applications will be reached from outside.

so if you dock in a large range of organizations , there is very good repo server itself.

to install the repo server, make sure there are big hard drive size, if 500GB is already inside your pc..so no problem Punyer.

its very easy to install,

sudo apt-get install apt-mirror

kemudian edit cron kat:

sudo nano /etc/cron.d/apt-mirror

tukar masa cron untuk auto setiap hari


by default all the downloads will be installed in a folder:

  /var/spool/apt-mirror

then  install apache2 dan buat symlink

by default all the downloads will be installed in folder default, the repo in the downloads are based on the Ubuntu version apt-mirror server is. To add edit and add the release that useful:

sudo nano /etc/apt/mirror.list

itu aje

wasslam
