設定IP

 

1.設定DNS  
/etc/sysconfig/network/config

FIREWALL="yes"

NETCONFIG_DNS_STATIC_SERVERS="192.168.0.x 168.95.192.1 8.8.8.8"

設定DNS  
/etc/resolv.conf

nameserver 192.168.0.x

nameserver 168.95.192.1

nameserver 8.8.8.8

(resolv.conf is overwritten with the info in dns-nameservers in /etc/network/interfaces)

/etc/hosts(早期的DNS)

 

2.設定ip address
/etc/sysconfig/network/ifcfg-eth0

BOOTPROTO='static' (dhcp)

BROADCAST=''

ETHTOOL_OPTIONS=''

IPADDR='192.168.0.x/24'

MTU=''

NAME=''

NETMASK=''

NETWORK=''

REMOTE_IPADDR=''

STARTMODE='auto'

DHCLIENT_SET_DEFAULT_ROUTE='yes'

 

3.設定default gateway
/etc/sysconfig/network/routes

default 192.168.0.x - -  

default gateway要修改routes(如果沒有要自行增加file routes,dhcp可能沒file)

修改主機名稱

要先檢查2個檔案

1. /etc/sysconfig/network/dhcp

DHCLIENT_MODIFY_SMB_CONF="yes"

DHCLIENT_SET_HOSTNAME="no"(留意這裡)

DHCLIENT_HOSTNAME_OPTION="AUTO"

DHCLIENT_SET_DEFAULT_ROUTE="yes"

DHCLIENT_ROUTE_PRIORITY="0"

 

2. /etc/hostname

主機名稱

套用新的設定

# systemctl restart network.service

指令修改host name

/etc/hostname

指令: # hostname newname

其他指令

#lspci | egrep -i --color 'network|ethernet'

# ifconfig

# ifstatus eth0

# route -n

# arp -a (Address Resolution Protocol)

(netstat -tlnp 

改成

sudo ss -tlnp | cat)

即時改ip and gateway

# ifconfig eth0 192.168.0.x netmask 255.255.255.0 up

# route add default gw 192.168.0.1

address reslution protocol

#arp -a

new tool

net-tools-deprecated

Deprecated Networking Utilities

which have been replaced by tools from the iproute2 package:

* arp -> ip [-r] neigh

* ifconfig -> ip a

* netstat -> ss [-r]
