This article mainly introduces what are the Ubuntu network configuration methods, the article is very detailed, has a certain reference value, interested friends must read it!

Ubuntu network configuration for example:

(1) configure the IP address of eth0 while activating the device. # ifconfig eth0 192.168.1.10 netmask 255.255.255.0 up (2) configure the IP address of the eth0 alias device eth0:1 and add routes. The network configuration command under # ifconfig eth0 192.168.1.3 # route add-host 192.168.1.3 dLINUX is ifconfig similar to ipconfig in the WINDOWS command line. You can use the ifconfig command to configure and view the configuration of the network interface.

1. For example:

(1) configure the IP address of eth0 while activating the device.

# ifconfig eth0 192.168.1.10 netmask 255.255.255.0 up

(2) configure the IP address of the eth0 alias device eth0:1 and add routes.

# ifconfig eth0 192.168.1.3

# route add-host 192.168.1.3 dev eth0:1

(3) activate the device.

# ifconfig eth0 up

(4) disable the device.

# ifconfig eth0 down

(5) View the configuration of the specified network interface.

# ifconfig eth0

(6) View all network interface configurations.

# ifconfig

2 、 route

You can use the route command to configure and view the configuration of the kernel routing table.

For example:

(1) routes added to the host.

# route add-host 192.168.1.2 dev eth0:0

# route add-host 10.20.30.148 gw 10.20.30.40

(2) routes added to the network.

# route add-net 10.20.30.40 netmask 255.255.255.248 eth0

# route add-net 10.20.30.48 netmask 255.255.255.248 gw 10.20.30.41

# route add-net 192.168.1.0 take 24 eth2

(3) add a default gateway.

# route add default gw 192.168.1.1

(4) View the configuration of the kernel routing table.

# route

(5) delete the route.

# route del-host 192.168.1.2 dev eth0:0

# route del-host 10.20.30.148 gw 10.20.30.40

# route del-net 10.20.30.40 netmask 255.255.255.248 eth0

# route del-net 10.20.30.48 netmask 255.255.255.248 gw 10.20.30.41

# route del-net 192.168.1.0 take 24 eth2

# route del default gw 192.168.1.1

For 1 and 2, you can use the following statement:

Ifconfig eth0 172.16.19.71 netmask 255.255.255.0

Route 0.0.0.0 gw 172.16.19.254

Service network restart

3 、 traceroute

You can use the traceroute command to display the route that packets take to reach the destination host.

For example:

# traceroute x

4 、 ping

You can use the ping command to test network connectivity.

For example:

# ping x

# ping-c 4 192.168.1.12

5 、 netstat

You can use the netstat command to display network status information.

For example:

(1) display network interface status information.

# netstat-I

(2) display the Socket of all the servers under monitoring and the program information that is using Socket.

# netstat-lpe

(3) display the information of kernel routing table.

# netstat-r

# netstat-nr

(4) display the connection status of the TCP/UDP transport protocol.

# netstat-t

# netstat-u

6 、 hostname

You can use the hostname command to change the hostname. For example

# hostname myhost

7 、 arp

You can use the arp command to configure and view the arp cache. For example:

(1) View the arp cache.

# arp

(2) add a corresponding record of IP address and MAC address.

# arp-s 192.168.33.15 00:60:08:27:CE:B2

(3) Delete a corresponding cache record for IP address and MAC address.

# arp-d192.168.33.15

Network configuration under Ubuntu command line

Edit the / etc/network/interface file as follows

Add first

Auto lo

Iface lo inet loopback

Auto eth0

If the ip is obtained automatically, add

Iface eth0 inet dhcp

If you are configuring ip manually, add

Iface eth0 inet static

Address xxx.xxx.xxx.xxx

Netmask xxx.xxx.xxx.xxx

Network xxx.xxx.xxx.xxx

Boardcast xxx.xxx.xxx.xxx

Gateway xxx.xxx.xxx.xxx
