Setting up DHCP client

Note: This is a basic demonstration for educational purposes. In a real network environment, DHCP servers typically serve multiple clients on a network.

Install DHCP Server: First, you'll need to install a DHCP server package if it's not already installed on your Linux system.
Start the DHCP Server: Before you work with client make sure your DHCP server is running. To start the DHCP server service use the following command:
```
sudo systemctl start isc-dhcp-server
```
Configure a DHCP Client: Configure a network interface to use DHCP:
```
sudo nano /etc/network/interfaces
```
Edit the file to look like this (assuming the interface is named "eth0"):
```
auto eth0
iface eth0 inet dhcp
```
Save the file and exit the text editor.
Restart the Network Service: To apply the DHCP configuration changes, restart the network service:
```
sudo systemctl restart networking
```
Monitor DHCP Server Logs: You can monitor the DHCP server logs to see lease assignments and client interactions. Use the following command to view the DHCP server logs in real-time:
```
sudo tail -f /var/log/syslog | grep dhcpd
```
Request an IP Address: You can manually trigger your Linux machine to request an IP address from the DHCP server by renewing its DHCP lease:
```
sudo dhclient -r  # Release the current lease
sudo dhclient    # Request a new lease
```
Check the logs to see the DHCP lease assignment.
