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.
<p>NDiff should be useful to network administrators, security analysts,
and other interested parties who need to monitor large networks in an organized
fashion. If your network is larger than even a few nodes your security
will likely be enhanced by integrating NDiff monitoring as part of your
security infrastructure.
<p>NDiff is known to work on Linux/x86. It should run fine on other POSIX/UNIX
platforms as well.
<p>NDiff requires
<a href="http://www.cpan.org/src">perl</a> 5.005_03 or
later and <a href="http://www.insecure.org/nmap">nmap</a> 2.53 or later.<!--
<p>
NMap is available from <A href="http://www.insecure.org/nmap">http://www.insecure.org/nmap</A>.
<p>
Perl is available from from all the usual places in
<A HREF="http://www.cpan.org/ports">binary</A> and
<A HREF="http://www.cpan.org/src">source</A> form.
