Use the dhclient command of linux to dynamically obtain or release IP addresses

Editor to share with you the use of linux's dhclient command to dynamically obtain or release IP address, I hope you will learn a lot after reading this article, let's discuss it together!

The function of the dhclient command is to dynamically configure the network parameters of the network interface using the dynamic host configuration protocol, and also support the BOOTP protocol.

Syntax format: dhclient [parameters] [Network Interface]

Common parameters:

-p specifies the port number that the dhcp client listens to (default port number 86)-d always runs the program in foreground mode-Q quiet mode, does not print any error message-r releases ip address-n does not configure any interface-x stops the running DHCP client without releasing the current lease, kills the existing dhclient-s to specify the DHCP server before obtaining the ip address-w even if the broadcast interface is not found Also continue to run

Reference example

Issue a DHCP request on the specified network interface:

[root@linuxcool ~] # dhclient eth0

Release the IP address:

[root@linuxcool ~] # dhclient-rKilled old client process

Obtain the ip address from the specified server:

[root@linuxcool] # dhclient-s 192.168.60.240

Stop running dhclient:

[root@linuxcool] # dhclient-xKilled old client process has finished reading this article.
