-
Practical Guide to Linux Commands, Editors, and Shell Programming, A (2nd Edition)
One of the operating system in our world is Linux (we have discuss a little about Chromium OS and Android). And this time we found a tools for changing your MAC address in Linux. This simple tool is TMAC.


In computer networking, a Media Access Control address (MAC address) is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification, and used in the Media Access Control protocol sub-layer. It may also be known as an Ethernet Hardware Address (EHA), hardware address, adapter address, or physical address.

TMAC, a simple bash program, written for the purpose of changing the MAC address of Network Interface Card (NIC) in Linux based system, provided it has Bash environment.

This tool attempts to change the MAC address of Network Inteface Cards (NIC) in Linux systems by choosing a randomly-generated MAC address. The chosen MAC address is randomised in following way:

  • It chooses it's first 3 octets needed for MAC address from a list of MAC vendors list provided from IEEE, which can be found here. 
  • The rest 3 octets are a set of complete randomly-generated hexadecimal numbers obtained with help of Psuedo-random-generator system variable. 

All it needs is a Linux machine with BASH shell environment.

Another joke from lolisoft today...   CORPORATE DIRECTIVE NUMBER 88-570471 In order to increase the security of all company computing facilities, and to avoid the possibility of unauthorized use of these facilities, new rules are being put into effect concerning the selection of passwords. All users of computing facilities are instructed to change their passwords to conform to these rules immediately. RULES FOR THE SELECTION OF PASSWORDS: 1. A password must be at least six characters long, and must not contain two occurrences of a character in a row, or a sequence of two or more characters from the alphabet in forward or reverse order. Example: HGQQXP is an invalid password. GFEDCB is an invalid password. 2. A password may not contain two or more letters in the same position as any previous password. Example: If a previous password was GKPWTZ, then NRPWHS would be invalid because PW occurs in the same position in both passwords. 3. A password may not contain the name of a
