restart eth0

(1) linux restarts the network interface

linux can restart by restarting service network restart or ifdown eth0 ifup eth0. For details, please refer to “Linux should learn like this”

㈡ ubuntu20 restart network card command

ubuntu restart network card method

View network card information: ifconfig

Set a network card IP: ifconfig eth1 192.168.1.10 netmask 255.255.255.0

Restart the network card to make the settings take effect: sudo /etc/init.d/networking restart

Using ubuntu system –> system Management -> Network settings of the network

Close the network card ifdown eth0

Open the network card ifup eth0

Restart the network card, the advantage is that the network card can be specified, not Affect other network interfaces

(iii) How to reload eth0 in linux

Temporary solution 1:
Use the command ifconfig eth0 192.168.1.x to work normally Set the IP of eth0. This method is only a temporary solution, and it will be invalid after the system restarts.

Permanent solution 2:
1. Create a new ifcfg-eth0 file in the /etc/sysconfig/network-scripts/ directory;
2. Correctly set the DEVICE of ifcfg-eth0 , BOOTPROTO, ONBOOT, IPADDR, GATEWAY, DNS1, DOMAIN, NETMASK, NETWORK, NAME, etc., for example:
DEVICE=eth0 physical device name
IPADDR=192.168.1.x IP address
NETMASK=255.255.255.0 Subnet mask
NETWORK=192.168.1.0 Specify the network, which is automatically calculated by IP address and subnet mask
GATEWAY=192.168.1.1 Gateway address
BROADCAST=192.168. 1.255 broadcast address, automatically calculated from IP address and subnet mask
ONBOOT=[yes|no] Whether to activate the device at boot
USERCTL=[yes|no] Whether non-ROOT users can control the device
br /> BOOTPROTO=[none|static|bootp|dhcp] Boot without protocol|static allocation|BOOTP protocol|dhcp protocol
HWADDR=00:13:D3:27:9F:80 MAC address
NAME=eth0 name
3. After the above settings, it can be successful under normal circumstances. If there is still a problem, add ifup eth0 at the end of the file /etc/rc.d/rc.local (/etc/rc. local scripts are executed after all other init scripts have been executed).
4. Restart the computer, OK.
Other network control commands:
ifdown eth0, ifconfig eth0 down //close the network
ifup eth0, ifconfig eth0 up //open the network
——— ——————————————————–
Set DNS configuration file location /etc/resolv.conf
———————————– ——————–
service network start //Start network service
service network stop //Stop network service
srvice network restart //Restart network service
service network status //View network service status

㈣ Linux restart network card method# service network restart, which network card is restarted
/p>

# service network restart is to restart all network cards.
For example, the following example:
>ifconfig eth0 up|down
>service network restart|start|stop
1. The former specifies the corresponding network card and the latter is all network cards
2. The former option has startup and shutdown and the latter has restart option.
That is: if the former has a restart effect, it needs ifconfig eth0 down && ifconfig eth0 up[remote operation needs attention]
3. The latter service operation and the former /sbin command operation have different permissions
In some cases, the service command will be used by root, while ordinary users can still use ifconfig in certain cases.

㈤ /etc/init.d/network restart cannot restart and display eth0

This seems to be garbled characters. In actual state, you can use ifconfig to check the network card information Whether the update is completed (if the minimum installation may not use this function, if not, you can check it through ip addr). However, in some versions /etc/init.d/network restart this method may not be used, only start and stop. It is recommended to use server network restart and systemctl restart network to restart the network card.

㈥ How to restart the network card in linux

In actual work, it is often encountered that the Linux system restarts the network card. Sort it out here, and restart the network card in various ways.

1. service network restart

1. First, use the CRT tool to connect to the Linux command line interface. Or enter the operating system interface and select terminal input.

2. If we restart all network cards. try to loseEnter: service network restart command to operate.

3. This completes the operation of restarting the network card with the service network restart command.

Second, ifconfig eth0 down / ifconfig eth0 up

1. Connect to the command line interface and enter ifconfig to view the basic information of the network card.

2. View the network card information of eth3. Enter ifconfig eth3 down to uninstall the eth3 NIC.

3. Enter ifconfig eth3 up and reload the eth3 network card.

Three, ifdown eth0 / ifup eth0

1. Connect to the command line interface. Enter ifdown eth3 to uninstall the network card eth3.

2. Enter ifup eth3 to reload the network card eth3.

Linux can restart the network in the following ways:

1. First, use the CRT tool to connect to the Linux command line interface. Or enter the operating system interface and select terminal input.

2. If restarting all network cards, you can try to input: service network restart command to operate.

3. The operation of restarting the network card with the service network restart command is completed, connect to the command line interface, and enter ifconfig to view the basic information of the network card.

4. View the network card information of eth3. Enter ifconfig eth3 down, unload the eth3 network card, enter ifconfig eth3 up, and reload the eth3 network card.

5. Connect to the command line interface. Enter ifdown eth3 to unload the network card eth3, enter ifup eth3 to reload the network card eth3.

㈦ How to solve the failure to start the network card eth0

1./etc/udev/rules.d/70-persistent-net.rules file
Delete eth0 network card
Change the NAME=”eth1″ of the eth1 network card to “eth0”, and copy the value (MAC address) in ATTR{address}
2./etc/sysconfig/network-scripts/ifcfg -eth0 file
Overwrite the copied ATTR{address} value with #HWADDR
Restart the service: service network restart
