IP address assignment

Interface configuration using DHCP service example:

#vi /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=dhcp HWADDR= 00-19-DB-AD-19-99 ONBOOT=yes

Interface configuration using manually set parameters:

#vi /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 HWADDR= 00-19-DB-AD-19-99 IPADDR=192.168.1.2 NETMASK=255.255.255.0 BROADCAST=192.168.1.255 GATEWAY=192.168.1.1 ONBOOT=yes DNS1=8.8.8.8 DNS2=8.8.4.4

To check the interface configuration:

ifconfig eth0

To check the routes:

netstat -r

To restart the interface and to apply the new settings:

ifdown eth0 - disable ifup eth0 - enable
