To renew the Dynamic Host Configuration Protocol (DHCP) lease on an Ubuntu Linux system, you can use the dhclient command with the renew option and the name of the network interface. The dhclient command is a client program that is used to request and obtain a DHCP lease for a network interface on a Ubuntu system.
Here's the command to renew the DHCP lease for the eth0 interface on an Ubuntu Linux system:
sudo dhclient -v -r eth0Secruo:www.lautturi.com
This command will release the current DHCP lease for the eth0 interface and request a new DHCP lease. The -v option enables verbose output, and the -r option forces the release of the current DHCP lease.
After running this command, the eth0 interface should obtain a new DHCP lease, and the network configuration for the interface will be updated with the new IP address, subnet mask, default gateway, and DNS servers.
Keep in mind that you must have the necessary permissions to run the dhclient command on your system. If you do not have the necessary permissions, the dhclient command will display an error message.
For more information on the dhclient command and how to use it on Ubuntu Linux systems, you can refer to the dhclient documentation or the Ubuntu documentation.
Alternatively, you can also use the dhcpcd command to renew the DHCP lease on an Ubuntu Linux system. The dhcpcd command is a DHCP client program that is used to request and obtain a DHCP lease for a network interface on a Ubuntu system. To renew the DHCP lease using the dhcpcd command, you can use the following command:
sudo dhcpcd -k eth0
This command will release the current DHCP lease for the eth0 interface and request a new DHCP lease. The -k option forces the release of the current DHCP lease and sends a broadcast request for a new DHCP lease.
For more information on the dhcpcd command and how to use it on Ubuntu Linux systems, you can refer to the dhcpcd documentation or the Ubuntu documentation.
