This article mainly explains "how to configure the network parameters of linux". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to configure the network parameters of linux.

Main uses:

1. View the network interface settings: ifconfig-an or ifconfig network interface-a

2. Network configuration ifconfig network interface [add/del] ip address netmask subnet mask example: ifocnfig eth0 10.2.3.4 [netmask 255.255.255.0]

3. Activation / shutdown format of network interface: ifconfig network interface up/down

Configure dns

Create a / etc/resolv.conf file and write the dns server address in it

Configure Hostnam

Configure the / etc/sysconfig/network file and modify the hostname using hostname

Examples of use:

The copy code is as follows:

[root@twin0898 sysconfig] # cat network

Network networking/ network-scripts/

[root@twin0898 sysconfig] # cat network

Networking=yes

Gateway=125.39.149.1

Hostname=twin0898

Networking_ipv6=no

Common format:

1. Gateway to the network route add/delete-net destination network netmask mask gw gateway address [dev network interface]

2. Gateway to a single host route add/delete-host destination host gw gateway address [dev network interface]

3. Add default gateway: route add default gw gateway address check host routing table: route,netstat-nr

/ / the summary is as follows:

1. Network configuration check: ifconfig-a

2. Connectivity check: ping, traceroute

3. Routing table check: route or netstat-nr

4. Check the running status of dns client: nslookup

/ / examples of use are as follows

/ / ifconfig-a

The copy code is as follows:

Root@cinematest2:/usr/local/jdk# ifconfig-a
