NDiff 0.05beta1 is available. This is a beta version released to enable integration with the NWatch tool. It has not been tested extensively so upgrade to this version is not recommended unless you intend to use NWatch. NWatch may be found at http://www.vinecorp.com/nwatch.
NDiff compares two nmap scans and outputs the differences. It allows monitoring of your network(s) for interesting changes in port states and visible hosts. NDiff eliminates the need to sift through voluminous raw scan output in search of the few noteworthy differences.
NDiff should be useful to network administrators, security analysts, and other interested parties who need to monitor large networks in an organized fashion.
This release includes several bug fixes and output formatting improvements, including html output for ndiff.
NDiff requires perl 5.005_03 or later and nmap 2.54 or later. It should run on any Unix system.
