Here the command I performed to cofigure srcd for network

Why -s? What does it do?
There should not be a need to use it.
dhclient eth0 alone will suffice.
But dhclient failed to configure. After that, I gave te below command
# ifconfig eth0 192.168.1.3 netmask 255.255.255.0
I also put the default gateway as follows
# route -v add 192.168.1.0 gw 192.168.1.3
# route -v add default gw 192.168.1.1
There is a problem here.
The first route add command is superfluous. The moment you assign an
IP address to an interface along with a subnet mask, the reachability
to all the hosts in that network is implicit.
The basic idea of routing is very simple.
Rule
#1 ) You can only use directly connected machine as the next hop.
Which is to say that the gateway should reside on the local
network/networks and should be reachable without any route.
The next hop in linux is specified as the argument to "gw"
parameter.
#2) There should not be more than default route
#3) Any router has at least two interfaces
There are more but this is sufficient for now.
after that I ping the server as
# ping 192.168.1.1
but It failed to detect the server.
but the local loopback is working correctly because when I ping for
192.168.1.3 it gives the correct output. I think this is not a network
driver priblem for srcd. But I am not able to connect the net through srcd.
I am a beginner on network with linux. I will be thankful if anybody help me
to solve this problem.
No problem. Routing is hard to understand.
Keep trying. You will succeed.
Best of luck!
