How to configure the network parameters of linux
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:
