The NETWORK and BROADCAST items are derived from the IPADDR and NETMASK items, but you can change them if you understand the consequences.Īt the centos you can use SETUP command in privilege ROOT. For instance, an option specifying the interface name ( DEVICE=eth0 ), another that tells the computer to assign a static IP address ( BOOTPROTO=static ), and a third to bring up the interface when the computer boots ( ONBOOT=yes ). The network configuration script may hold additional options, but most of these are related to others. The gateway isnt necessary on a system that isn t connected to a wider network that is, if the system works only on a local network that contains no routers.ĭNS Settings For Linux to use DNS to translate between IP addresses and hostnames, you must specify at least one DNS server in the /etc/nf file. In either case, the option is likely to be called GATEWAY. To set it permanently, you need to adjust a configuration file, which may be the same configuration file that holds other options or another file, such as /etc/sysconfig/network/routes. Gateway Address: You can manually set the gateway with the route command. Network Mask : You can set the netmask manually with the ifconfig command or with the NETMASK item in a configuration file. IP Address : You can set the IP address manually with the ifconfig command or with the IPADDR item in the configuration file. To set a static IP address in the long term, you adjust a configuration file such as /etc/ sysconfig/network – scripts/ifcfg – eth0 or /etc/network/interfaces.
