A Perl script eliminates null session shares to secure remote
systems  Early in my life as a network administrator, I fought
many battles just trying to keep my network together. Because
the original architects of the network never really planned for
pesky tasks such as checking security, I had to implement cheap
but effective methods to query settings on remote machines. So I
did what all good administrators do: I wrote a script.  I wrote
the script in Perl. For those who are unfamiliar with Perl, it's
a powerful, extensible open-source scripting language. It has
been ported to most platforms (e.g., UNIX, Macintosh, Win32,
VMS), so you can use it to write scripts that can run on all
your systems.The script interacts with the Win32 registry, which
stores most of Win32's configuration information, to check some
settings for security purposes. The script implements a simple
form of autodiscovery to ensure that it inspects all machines on
the network.  Scripting in Perl Perl has been around for more
than 10 year
