NTA's tools
NTA has developed a variety of tools that website visitors are welcome to download.
The Address Resolution Protocol (ARP) is the method for finding a host's hardware address when only its IP address is known. This tool runs on Linux and allows host detection and fingerprinting using the ARP protocol.
Ike-scan was developed by NTA's Technical Director Roy Hills and released in 2003 under the GNU General Public Licence (GPL). Ike-scan exploits transport characteristics in the Internet Key Exchange (IKE) service, the mechanism used by VPNs to establish a connection between a server and a remote client. It scans IP addresses for VPN servers by sending a specially crafted IKE packet to each host within a network.
