Nmap and 12 useful NSE scripts.

Nmap is the most popular free security scanner developed by Gordon Lyon (f.f. Fyodor Vaskovich). The first version of Nmapa was published on October 1, 1997, in the online magazine, Phrack.

For those interested in the beginnings of this scanner, here is a full article that shows the capabilities and source code of the first version of Nmap: The Art of Port Scanning.

At the time of writing this text, the latest version of Nmap is 7.70. This version is equipped with 588 NSM scripts (Nmap Scripting Engine), which, along with a huge number of standard scanning options, give the opportunity to examine more carefully the hosts we are interested in.

NSE can be used, among others, to more accurately detect the version of a given service, break usernames and passwords, detect and use known vulnerabilities, and even detect existing back gates left by the attacker and fuzzing.

A list of all available scripts with descriptions is published at https://nmap.org/nsedoc/. Alternatively, to get a list, we can use the terminal (assuming that Nmap has been installed in the default location): read more....

Fixing Unix/Linux/POSIX Filenames

Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned.

Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....

Debian and Windows Shared Printing.

Debian GNU/Linux ( http://www.debian.org ) is the premier volunteer-supported Linux distribution. Unfortunately, setting up printers in Debian can be difficult. Also, simple step-by-step instructions for sharing printers between Windows and Linux using the latest tools are hard to find. This HOWTO was written to address both problems. This HOWTO will demonstrate how to use command-line tools to configure your Debian system for printing. It will explain how to send documents from Linux to Windows printers and how to share Linux printers with Windows PCs. Some troubleshooting examples are also given.
