Thanks for your immediate Response

I think you hardware may have only a configuration issue
What kind of network or external device are you trying to connect...?
1) - a local area network
2) - a ethernet modem/router

Thank you.

Iam using Local Area Network only and the connected speed is 10Mb .
When iam using Windows XP i will configure link speed to 10Mb Half duplex then only net used to work.

Dear marcobra,

Firstly iam thankful for your interest in solving this problem. Iam very happy to know this is only a congfiguration issue. I thought of this is some major problem and i was so depressed even. I will be very thankful to you if you can solve my problem as soon as possible.

Thanking you.

Please boot this pc in Windows and from the windows menu:
start->run
type cmd press enter
Then type:
ipconfig
press enter
try to read your windows assigned ip number.

Please copy and paste it here.
Thank you

Dear Marcobra,

I booted my pc as you said. Here is the data which i got it by running ipconfig

Windows IP Configuration
Ethernet adapter Local Area Connection:
        Connection-Specific DNS Suffix : bits-pilani.ac.in
        IP Address : 172.23.1.93
        Subnet Mask : 255.255.255.0
        Default Gateway : 172.23.1.254

Thanking you

Please first try to configure your network as DHCP client
Open menu System->Administration->Network-> Wired Connection : properties
and try first to configure your eth0 and eth1 as dhcp
and restart your network layer, open a Terminal from the menu
Applications->Accessories->Terminal and type:

sudo /etc/init.d/networking restart

give your user password when requested, you don't see nothing when you type it, then press enter.

Try to use your network

----------------------------------------------------------------------------
If upper instructions don't make your network work
-------------------------
Please configure your nics first eth0 and then eth1 like the Windows configuration
Open menu System->Administration->Network-> Wired Connection : properties
Select -> Static ip address and specify
IP Address : 172.23.1.93
Subnet Mask : 255.255.255.0
Default Gateway : 172.23.1.254
for the dns use opendns server or your
DNS: 208.67.222.222 and 208.67.220.220

Restart your network: open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo /etc/init.d/networking restart

give your user password when requested, you don't see nothing when you type it, then press enter.

Try to use your network

Hope this help

Dear Marcobra,

After Configuring the network to DHCP and restarting the results i got the below message

ramakrishna@Eureka-desktop:~$ sudo /etc/init.d/networking restart

The Same thing for eth1

after configuring to static ip and restarting the network the message i got is
ramakrishna@Eureka-desktop:~$ sudo /etc/init.d/networking restart
 * Reconfiguring network interfaces... [ OK ]

In either case my net is not working.
Thanking you

Try to get the ip address of some different devices connected to your network...
Please ping that ip address from your ubuntu pc open a terminal and type:

ping 172.23.1.NNN

or try to ping your gateway

ping 172.23.1.254

Please give us some feedback
Thank you

Dear Mar cobra,

Thanks for your reply,
I have discussed this problem with one of my friend and he suggested me to do this
su root
password
mii-tool -F 10baseT-HD
sudo /etc/init.d/networking restart
mii-tool -R

After these number of commands my net starts working and i was delightful.
But he told me do this every time I boot in to ubuntu.
is there any permanent solution by which it can work with out entering any more commands after i boot because this system will be used by my parents who are not familiar with this OS.
looking forward for your reply soon.

Thank You

Thanks marcobra, that solved my question.
