5.3.4. The network interface served by the DHCP

After prepairing the system by Section 5.2.1, “The DHCP connection with the Ethernet”, the network interface served by the DHCP is configured by creating the configuration entry in the "/etc/network/interfaces" file as the following.

allow-hotplug eth0
iface eth0 inet dhcp
 hostname "mymachine"

When the Linux kernel detects the physical interface eth0, the allow-hotplug stanza causes ifup to bring up the interface and the iface stanza causes ifup to use DHCP to configure the interface.

5.3.5. The network interface with the static IP

The network interface served by the static IP is configured by creating the configuration entry in the "/etc/network/interfaces" file as the following.

allow-hotplug eth0
iface eth0 inet static
 address 192.168.11.100
 netmask 255.255.255.0
 broadcast 192.168.11.255
 gateway 192.168.11.1
 dns-domain lan
 dns-nameservers 192.168.11.1

When the Linux kernel detects the physical interface eth0, the allow-hotplug stanza causes ifup to bring up the interface and the iface stanza causes ifup to use the static IP to configure the interface.

Here, I assumed the following.

• IP address range of the LAN network: 192.168.11.0 - 192.168.11.255
• IP address of the gateway: 192.168.11.1
• IP address of the PC: 192.168.11.100
• The resolvconf package: installed
• The domain name: "lan"
• IP address of the DNS server: 192.168.11.1

When the resolvconf package is not installed, DNS related configuration needs to be done manually by editing the "/etc/resolv.conf" as the following.

nameserver 192.168.11.1
domain lan
