How to map network

Filed under: Security Tools,Tech Related — Suramya @ 4:02 AM

If you ever had to find all of the IP’s of the routers and computers on a network then these programs are for you. I havn’t tried them myself yet but they look promising. (The descriptions are taken verbatin from their respective websites)

Angry IP Scanner:

Angry IP scanner is a very fast IP scanner for Windows. It can scan IPs in any range. Its binary file size is very small compared to other IP scanners. Angry IP scanner simply pings each IP address to check if it’s alive, then optionally it is resolving hostname, scans ports, etc.


A powerful connect-based TCP port scanner, pinger and hostname resolver. Multithreaded and asynchronous techniques make this program extremely fast and versatile. Perform ping scans and port scans using any IP range or specify a text file to extract addresses from.


Cheops is an Open Source Network User Interface. It is designed to be the network equivalent of a swiss-army knife, unifying your network utilities.

As usual if you know of any others let me know.

MS Word Clone for Linux

Filed under: Computer Software,Tech Related — Suramya @ 4:30 AM

TextMaker is a word processor that launches lightning-fast, needs little memory, does not require complicated setup and still has the full feature set of a modern high-end word processor. It reads and writes Microsoft Word 6/95/97/2000/XP/2003 files without losing formatting or content.

The biggest advantage in my book is that it doesn’t look ugly. -) Try it out. They have a free trial available which lets you read .doc files but doesn’t let you save in it.

Role-Based Access control

While Mandatory Access Controls (MAC) are appropriate for multilevel secure military applications, Discretionary Access Controls (DAC) are often perceived as meeting the security processing needs of industry and civilian government. This paper argues that reliance on DAC as the principal method of access control is unfounded and inappropriate for many commercial and civilian government organizations. The paper describes a type of non-discretionary access control – role-based access control (RBAC) – that is more central to the secure processing needs of non-military systems then DAC.

Installing Debian From Scratch (DFS)

Filed under: Knowledgebase,Linux/Unix Related — Suramya @ 5:00 PM

I like Debian a lot, the only problem I have with it is that when I install it, it installs a lot of junk on the system that I don’t need.

Linux from Scratch is a distribution that fixes this problem but setting it up is too much work for me plus I really like debian and would like to stick to it. -) Fortunately for me someone else also felt the same and created DFS which allows you to create a customized install like LFS but with the Debian advantages.

Instructions on how to install Debian From Scratch are available here

I will try to install it on my system over the weekend. Will keep you posted.
