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....

Debugging Perl

The standard Perl distribution comes with a debugger, although it's really just another Perl program, perl5db.pl. Since it is just a program, I can use it as the basis for writing my own debuggers to suit my needs, or I can use the interface perl5db.pl provides to configure its actions. That's just the beginning, though. read more...

Perl wlan-ui

wlan-ui.pl is a program to connect to wireless networks. It can be run as a GUI which will offer a list of available networks to connect to.nstallation is simple and inelegant. Copy the program file (wlan-ui.pl) to a directory on your path. Next, create a new system configuration file to reflect your system. The system configuration file is different from the options configuration file (@configfile, above). The system configuration file tells the program how to configure the wireless interface, and the options configuration file sets defaults for access points and other things.

Reducing NumPy memory usage with lossless compression.

If you’re running into memory issues because your NumPy arrays are too large, one of the basic approaches to reducing memory usage is compression. By changing how you represent your data, you can reduce memory usage and shrink your array’s footprint—often without changing the bulk of your code. In this article we’ll cover:     * Reducing memory usage via smaller dtypes.     * Sparse arrays.     * Some situations where these solutions won’t work.
