Syn 'N Destroy ! (Update new version)

It's time to introduce Synator a new Ultra Fast TCP Port Scanner based on the Syn Scan technique (You have already guessed that by the name right ?). It is very similar to Synscan (http://www.bindshell.net/tools/synscan) but a lot easier to use and require no compilation, it uses the libraries from SinFP (http://www.gomor.org/bin/view/Sinfp) to handle all the low level network interaction.

Why using it ? :

Now why would you use this tool instead of the widely used nmap port scanner ?

1. Because you don't like to wait
2. Because when nmap receives his acknowledgments a bit slowly (slow network or slow server) it reduces the scan speed (it takes sometime 10 minutes or more).
3. Because you have a huge IP range to scan and you want to be able to scan 65535 ports on all IP in a reasonable delay.

Features:

• Simple & efficient design
• Service identification using amap
• Source Port option
• Fast scan based on Nmap Top port
• Fexible Slow scan to avoid scan detection (-d and -m option)
  

Performances:

• On a good LAN network it takes approximately 2m30 sec to scan all open ports of a host.
• On Internet it is quite variable but tends to settle around 2 minutes (from 1m20 sec to 2m40) when using a high speed connection against a Fast server (ideal conditions ...).
  

Online Help:

Here is the help message when your launch the synator without any parameter

Usage: bin/Synator2v1.pl
[-h IP]
[-s tcp|udp]
[-f OutputFilename]
(-p Destination PortNumber)
(-S Source PortNumber)
(-b Service Banner Grabbing)
(-c ShowClosedPort)
(-d DelayInSeconds)
(-m maxSynPacketBeforeDelay)
Options -p support multiple value separated by ',' and '-' ie 21,80 or 1-100.

Important Note:

• Using a hostname instead of an IP address is not supported yet (is it really useful ?)
  
• Avoid scanning with a wifi card
• Avoid using synator inside a Virtual Machine, there is a high performance drop !

Known Bugs or limitations:

• Synator does not work with some wifi card like the WPN311, this is bug due to libdnet that is unable to get the network configuration from the card "addr_net: undef input".

TODO:

• Perform DNS resolution when a hostname is given as IP
