Hello,
****************
What I need :
****************
I need to write a scanner that test all the IP adresses that repond on
a given port.
The Ip list is of roughly of length 200.
I need to get the response every 60 seconds (or better).
I would prefer first not to use nmap.
****************
Configuration :
*****************
Python 2.4.1.
To test what is going on I use ethereal.
I am using winXP pro on a 2GHZ P4 and 512 Mo.
***********
Problem :
***********
I tried to implement a simplistic threaded version where each thread is
opening a blocking socket on the IP and port.
I have monitored using etherereal that I get one arp query every second
roughly.
I am expecting a speed on the same oder of magnitude as the one that
one can get from a standard IP/port scanner. To compare, I have used
angry Ip scanner and I have seen that roughly 200 arp request where
sent in 20 seconds.
*******
Also :

I have also considered using some asynchrone connection but AFAIK you
need first to open the socket and so to use the arp protocol.
Thanks I advance for your help.
Sebastien.
