On my local network, 0.5 was more than enough. 5.0 seconds on my VPN seemed to be enough to work properly consistently, less didn't (always) give accurate results.

Print '%s:%d - closed (%d)' % (address,p,result) #do nothing, was a timeout, probably host doesn't exist The example below finds which IPs on the VPN that have VNC/port 5900 open with the client running on Windows 7.Ī short Python (v2.6.6) script to scan a given list of IPs and Ports: from socket import *Īddress = ('%s.%d' % (sNetworkAddress, h)) Since there is no appeal available for the delete, I am reposting it to save others the frustration I had with trying to use the other answers.
This answer was previously deleted and should not have been, as this is the only solution for a real-world common case. This will create a directory called aircrack-ng-1.6-win. Unzip the contents of the Aircrack-ng zip file into C. The link for the zip file can be found on the Wiki home page. This is the only solution that works for VPNs with the client machine being Windows Vista or Windows 7, as other listed answers simply do not function. Here are the steps to follow for Windows: Download the latest version of the Aircrack-ng suite for Windows to your computer.
