NSE – The Nmap Scripting Engine for Automated Tasks

The Nmap Scripting Engine (NSE) is one of Nmap’s most powerful and flexible features. It allows users to write (and share) simple scripts to automate a wide variety of networking tasks. Those scripts are then executed in parallel with the speed and efficiency you expect from Nmap.

All existing scripts have been improved, and 32 new ones added. New scripts include a whole bunch of MSRPC/NetBIOS attacks, queries, and vulnerability probes; open proxy detection; whois and AS number lookup queries; brute force attack scripts against the SNMP and POP3 protocols; and many more. All NSE scripts and modules are described in the new NSE documentation portal.

Count from one to ten in binary

Counting in binary:
Counting in binary is similar to counting in any other number system. Beginning with a single digit, counting proceeds through each symbol, in increasing order. Decimal counting uses the symbols 0 through 9, while binary only uses the symbols 0 and 1.

Decimal and Binary jump to the left:
When the symbols for the first digit are exhausted, the next-higher digit (to the left) is incremented, and counting starts over at 0.

In decimal, counting proceeds like so:
000, 001, 002, … 007, 008, 009, (rightmost digit starts over, and next digit is incremented)
010, 011, 012, … …
090, 091, 092, … 097, 098, 099, (rightmost two digits start over, and next digit is incremented)
100, 101, 102, …

Decimal from 0-9 then left Binary from 0-1 then left:
After a digit reaches 9, an increment resets it to 0 but also causes an increment of the next digit to the left. In binary, counting is the same except that only the two symbols 0 and 1 are used.

After a digit reaches 1 in binary, an increment resets it to 0 but also causes an increment of the next digit to the left:
0000,
0001, (rightmost digit starts over, and next digit is incremented)
0010, 0011, (rightmost two digits start over, and next digit is incremented)
0100, 0101, 0110, 0111, (rightmost three digits start over, and the next digit is incremented)
1000, 1001, …

Count from 1 to 10 in Binary
Dec Bin
0 = 0
1 = 1
2 = 10
3 = 11
4 = 100
5 = 101
6 = 110
7 = 111
8 = 1000
9 = 1001
10 = 1010
11 = 1011
12 = 1100
13 = 1101
14 = 1110
15 = 1111
16 = 10000

Base 2 System:
Since binary is a base-2 system, each digit represents an increasing power of 2, with the rightmost digit representing 20, the next representing 21, then 22, and so on. To determine the decimal representation of a binary number simply take the sum of the products of the binary digits and the powers of 2 which they represent.

For example, the binary number:100101 is converted to decimal form by:
[(1) × 25] + [(0) × 24] + [(0) × 23] + [(1) × 22] + [(0) × 21] + [(1) × 20] =
[1 × 32] + [0 × 16] + [0 × 8] + [1 × 4] + [0 × 2] + [1 × 1] = 37
To create higher numbers, additional digits are simply added to the left side of the binary representation.
