Assuming
eth0 represents the Ethernet interface that is connected to your local network, you can use the following to temporary configure your system to connect to the network:
Code:
ifconfig eth0 192.168.1.100 netmask 255.255.255.0 up
Maybe you have a router interface configured at 192.168.1.1/24. Use this address as the gateway and check if you can send traffic to remote computers:
Code:
route add default gw 192.168.1.1
Finally, your DNS name server address is invalid. You can use Google's public DNS name servers:
Code:
echo "nameserver 8.8.8.8" >> /etc/resolv.conf && echo "nameserver 8.8.4.4" >> /etc/resolv.conf
You should try to get a better understanding of your network...
