My Network Tools
I have tried to understand the various
network tools available. Just by logging on to the Internet, how much
information are we passing about ourselves to others without our knowledge
? The various tools were tried one by one.
seems to be the first tool that anybody uses to check a network connection.Is
it an abbreviation ?...
What will I do if I want to know the IP address of another machine on
the net if I know its name? I tried to explore ....
I trace the path taken by a packet once it leaves my machine? It seems
I can ....
word is more self explanatory. Find out how useful it is ...
* Proxy test
thought connecting to Internet via a proxy would hide a great
deal of information about me from the Intrenet. I was wrong .
Here are the results ...
Can I specify an IP address as
http://3626046468/ instead of www.angelfire.com (220.127.116.11)
. They say you can. What is the conversion like? Convert these numbers to
hex individually. Concatenate them and then convert them back from
hex, you'll get your number! Obviously you
can reverse this to get back to the original IP address.
So, 18.104.22.168 = D8 21 14 04 (in
HEX) = 3626046468
Netscape did not accept my request.
But on pinging I got the result:
PING 3626046468 (22.214.171.124) from 126.96.36.199
: 56(84) bytes of data.
My first XML Page
Having heard a lot about XML, I decided
to understand what it is, how it is different from html and create
my first XML document.
Not very nice !!! It does not have a stylesheet.
So I created my first CSS. Now my document looked
a bit better.View
I then tried with xsl and created the
XSL stylesheet.Adding that to my document
the document looked like this. View
I have tried to use Xlinks and Xpointers in an

A brief on the evolution of Internet as recorded in
Here I have tried to learn
more about the underlying technologies of the Internet.
* Network monitoring
are used to determine what ports (or similar protocol abstraction) of a
host are listening for connections. These ports represent potential communication
channels. Mapping their existence facilitates the exchange of information
with the host, and thus it is quite useful for anyone wishing to explore
their networked environment, including hackers. Despite what you have heard
from the media, the Internet is NOT all about TCP port 80.
* Gigabit Ethernet
The Ethernet technology was limited to a speed of 100 Mbps or so I
thought. Then I came across this technology. I have tried to
understand the Ethernet technology and Gigabit ethernet in particular.
What are the differences that has enabled transfer speeds upto
10 Gigabits per sec using the same standard?
