Ike-scan

Ike-scan : VPN detector/scanner
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. Most hosts running IKE will respond, identifying their presence. The tool then remains silent and monitors retransmission packets. These retransmission responses are recorded, displayed and matched against a known set of VPN product fingerprints. Ike-scan can VPNs from manufacturers including Checkpoint, Cisco, Microsoft, Nortel, and Watchguard.

Nbtscan

Nbtscan : Gathers NetBIOS info from Windows networks
NBTscan is a program for scanning IP networks for NetBIOS name information (similar to what the Windows nbtstat tool provides against single hosts). It sends a NetBIOS status query to each address in a supplied range and lists received information in human readable form. For each responded host it lists IP address, NetBIOS computer name, logged-in user name and MAC address. The original nbtscan was written by Alla Bezroutchko. Steve Friedl has written an alternate implementation.

THC Amap

THC Amap : An application fingerprinting scanner
Amap is a great tool for determining what application is listening on a given port. Their database isn’t as large as what Nmap uses for its version detection feature, but it is definitely worth trying for a 2nd opinion or if Nmap fails to detect a service. Amap even knows how to parse Nmap output files. This is yet another valuable tool from the great guys at THC.
