To configure a Linux system as a static DHCP client by sending a host name to the DHCP server, you can follow these steps:
Open the /etc/dhcp/dhclient.conf file in a text editor.
Add the following line to the file:
send host-name "myhostname";
Replace myhostname with the host name you want to send to the DHCP server.
Save the file and close the text editor.
Restart the DHCP client service. You can do this by running the following command:
systemctl restart dhclient
This will restart the DHCP client service and send the host name specified in the dhclient.conf file to the DHCP server.
You can find more information about the dhclient.conf file and its options in the Linux documentation or by searching online.
Keep in mind that the host name you specify in the dhclient.conf file will be sent to the DHCP server whenever the DHCP client service is restarted. If you want to change the host name that is sent to the DHCP server, you will need to edit the dhclient.conf file and restart the DHCP client service.
