Set a fixed ip address for the NIC in Redhat linux

Previously, the redhat-config-network setting of the NIC fixed ip address in xwindow did not work. after the redhat-config-network is set, the ping fails. Check some information, change/etc/sysconfig/network-scripts/ifcfg-eth0 (the first Nic is eth0), configure the dns file as/etc/resolv. conf, I keep the dhcp configuration. After configuration, use ifconfig eth0 down; ifconfig eth0 up. The following is a configuration file list:

#/Etc/sysconfig/network-scripts/ifcfg-eth0:

DEVICE = eth0

BOOTPROTO = static

BROADCAST = 192.168.1.255

IPADDR = 192.168.1.10

NETMASK = 255.255.255.0

NETWORK = 192.168.1.0

HWADDR = 52: 54: AB: 2F: CF: F0

GATEWAY = 192.168.1.1

ONBOOT = on

TYPE = Ethernet

#/Etc/resolv. conf

Nameserver 202.109.14.5

Nameserver 202.96.209.5

Search localdomain

Or run the following command: setup

Or:

Route add-net 192.168.1.50 netmask 255.255.255.0 dev eth0

Or:

Ifconfig eth0 192.168.1.50 netmask 255.255.255.0

Ubuntu Nic settings, ip, mask, gateway, dns

Sudo vi/etc/network/interfaces

// This should determine whether to enable this port

Auto eth0

// Set the IP address statically

Iface eth0 inet static

Address 172.16.146.200

Netmask 255.255.255.0

# Broadcast 172.16.146.255

Gateway 172.16.146.254

// Dynamic settings through dhcp

Iface eth0 inet dhcp

// Set the DNS server

Sudo vi/etc/resolv. conf

Nameserver 202.96.128.68

Nameserver 61.144.56.101

Nameserver 192.168.8.220

// Reset the network to enable the new settings

Sudo/etc/init. d/networking restart

// OK
