Re: IP ADDRESS OF MACHINE


OK After reading Mr Rupert Wood's post I decided that enough is enough
and decided to test whether a NetWork Card is installed on my system or
not.

So I connected an Internet Router to my Linux computer. If there is a
NetWork Card installed on my computer then I should be able to access
the Internet.

And voila, there is a NetWork Card installed on my system.

I had already set the Computer's TCP/IP Address to 192.168.0.2. The
Internet router's address was set to 151.137.54.204

So by accessing the internet I was able to confirm that there is indeed a
NetWork Card on my computer.

But I decided to explore a bit further. I came across a command /bin/netstat

I ran this command /bin/netstat --route

This was the output that I got:

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.0.2     *               255.255.255.255 UH        0 0          0 eth0
192.168.0.0     *               255.255.255.0   U         0 0          0 eth0
127.0.0.0       *               255.0.0.0       U         0 0          0 lo
default         151.137.54.204   0.0.0.0         UG        0 0          0 eth0

I am now slowly able to understand some of the Jargon that Mr Rupert wood was using.
He talked about interfaces and I understand now that there is a EtherNet Interface
eth0 installed on my system.

So now this is the final-most-precise-version of my question:

I have a EtherNet Interface eth0 installed on my system. The TCP/IP Address of
my computer has been set to 192.168.0.2.

I wish to develop a C/C++ program that can retrieve the local computer's TCP/IP Address.

I DONT WANT THE PROGRAM TO SEARCH IN THE /etc/hosts FILE WHICH IS I BELIEVE USED FOR
A DIFFERENT PURPOSE.

In short I am looking for a program like /bin/netstat --route only this program is to be
much much much simpler. It just needs to retrieve the TCP/IP Address 192.168.0.2 and display
it.

Thanx for everybody's inputs here.

Awaiting a final reply.
