These are just few and most awesome features that i mentioned,Metasploit have many , many features for more visit official website. It won't help if we just learn theoretical stuff more you play around with Metasploit more you will discover it.So let's jump to the practical part.Open your terminal.


Start postgresql database

Before starting Metasploit we must start postgresql services.Below command starts database to store all of the metasploit exploits.So everytime you use METASPLOIT you must start postgresql services. It runs little faster with postgresql:

root@seven:~# service postgresql start

Start Metasploit

Now let's start metasploit:

root@seven:~# msfconsole

metasploit

When your metasploit starts you will be presented with above or may be different banner.Now you are inside Metasploit.


Now Check whether you are connected with Metasploit database or not.If you get the message connected to Msf then everything is good.

msf > db_status
[*] postgresql connected to msf

Change banner

The below command generates random banners.

msf > banner

Clear

If you want to clear or get rid of banners or clear terminal then just type:

msf > clear

Help

If you need any help then just type ? mark it brings up help menu.It displays all the commands with short descriptions.

sf > ?

You can always filter exploits according to your need.Lets say you want to find an exploit related to ftp just type the following:

msf > search ftp

Detailed information and usage of specific Exploit

If you want to find detailed information and usage of a specific exploit then type the following command. Just write info and paste or write the exploit name. I have picked ftp_login exploit it looks juicy. This is useful.

msf > info auxiliary/scanner/ftp/ftp_login 

       Name: FTP Authentication Scanner
     Module: auxiliary/scanner/ftp/ftp_login
    License: Metasploit Framework License (BSD)
       Rank: Normal

In order to use an exploit you have to write use and give exploit name that you want to use.

msf > use auxiliary/scanner/ftp/ftp_login 
msf auxiliary(ftp_login) >

Configure exploit

Show options command displays the configurations to set the exploit.Now when we are inside the exploit just type the below command it will show you the options that you need set to run the exploit.

msf auxiliary(ftp_login) > show options

Exploit

Once you have configured the exploit and are ready to attack.Write the below command to launch exploit

msf auxiliary(ftp_login) > exploit

modify source code of an exploit

You can actually add your own code into the Metasploit's exploit.With the below command you can see and modify the source code of an exploit. This is freaking awesome if you are a programmer what else you need you can a lot.But remember you need to be inside the exploit.

msf auxiliary(ftp_login) > edit

If you want to go one step back then write the back command:

msf auxiliary(ftp_login) > back

Show payloads

Check out all the payloads in Metasploit.

msf > show payloads

Payloads
========

Run Nmap commands inside Metasploit

You can run all the nmap commands inside metasploit. Example:

msf > nmap -F linuxxcomputing.com
[*] exec: nmap -F linuxxcomputing.com


Starting Nmap 6.49BETA4 ( https://nmap.org ) at 2015-12-19 13:19 EST
Nmap scan report for linuxxcomputing.com (107.180.0.245)
Host is up (0.18s latency).
rDNS record for 107.180.0.245: ip-107-180-0-245.ip.secureserver.net
Not shown: 86 filtered ports
PORT     STATE  SERVICE
21/tcp   open   ftp
22/tcp   open   ssh

Exit

Exit command will exit or quit Metasploit.It returns you to the main Linux shell /terminal.

msf > exit

I hope it helped you please share it among your friends.
