The main configuration file is /etc/network/interfaces

if you're using dhcp, it should look something like:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

..... or if using a static IP address:
auto eth0
iface eth0 inet static
address         192.168.1.10
netmask         255.255.255.0
network         192.168.1.0
broadcast       192.168.1.255
gateway         192.168.1.1

To start and stop services:

/etc/init.d/networking [start|stop|restart]

Looks OK.  Can you post the output of:

# ifconfig

Mail transport application - probably exim4; you may need to
reconfigure:

# dpkg-reconfigure exim4-config
