Netmask 255.255.255.0

Network 192.168.1.0

Broadcast 192.168.1.255

Gateway 192.168.1.2

# Dns-* options are implemented by the resolvconf package, if installed

Restart the NIC:/etc/init. d/networking restatr

Set the IP address in the command line of redhat linux:

Ifconfig eth0 new ip

Then edit/etc/sysconfig/network-scripts/ifcfg-eth0 and modify the ip

1. Modify the IP address

[Aeolus @ database network-scripts] $ vi ifcfg-eth0

DEVICE = eth0

ONBOOT = yes

BOOTPROTO = static

IPADDR = 219.136.241.211

NETMASK = 255.255.255.255.128

GATEWAY = 219.136.241.254

2. Modify the Gateway

Vi/etc/sysconfig/network

NETWORKING = yes

HOSTNAME = Aaron

GATEWAY = 192.168.1.1

3. Modify DNS

[Aeolus @ db etc] $ vi resolv. conf

Nameserver 202.96.128.68

Nameserver 219.136.241.206

4. Restart Network Configuration

/Etc/init. d/network restart

V. Example

1. Modify the IP address
