Redhat: Network Config files

Network Configuration Files

All of the files used to configure the networks are stored in two locations:

/etc/sysconfig/network /etc/sysconfig/network-scripts

The network scripts defined the configuration for each network adaptor. They are stored in files named ifcfg-<device>, one for each adapter.

These files use directives to configure the network. They are not always used.

BROADCAST	Broadcast Address	Only used for STATIC
DNS1	DNS server Address
GATEWAY	Gateway Address
IPADDR	IP Address	Only used for STATIC
HWADDR	MAC Address of the device

NM_CONTROLLED	Is the device controlled by the Network Manager	Yes or No
