Path To Pig.py / Exhaust Dhcp Addresses Basic

Exhaust Dhcp Addresses Basic

Exhaust DHCP addresses in a basic scenario using a specified network interface.

$
Terminal
sudo <path/to>/pig.py <eth0>

When To Use

To identify available DHCP addresses for testing network allocation mechanisms.

Pro Tip

Monitor DHCP lease time closely; rapid requests can lead to IP address depletion in real networks.

Anatomy of Output

Understanding the result

Requesting DHCP address from eth0... Request Status

Indicates the interface that is sending the request.

Assigned IP: 192.168.1.10 Assigned IP

Shows the IP address assigned by the DHCP server.

DHCP Lease Time: 86400 seconds Lease Time

Gives the duration for which the IP address is valid.

Power User Variants

Optimized versions

path-to-pig.py sudo path/to/pig.py eth0

Basic method to exhaust DHCP addresses.

path-to-pig.py sudo path/to/pig.py --retry eth0

Attempt retry on failed DHCP requests.

Troubleshooting

Common pitfalls

Error: DHCP request timed out

Solution: Check network connectivity and DHCP server status.

Error: Interface eth0 not found

Solution: Verify that the specified interface is correct and active.

Error: No DHCP server found

Solution: Ensure that the DHCP server is operational in your network.
