Determining the Vendor by MAC

When performing a recon on a network, whether wireless or LAN based, you may come across devices identified by its MAC address. To get a better footprint of the environment, it is definitely useful to determine the type of device riding within the enterprise. This can usually be done by an nmap sweep of the local environment. Once MAC addresses are gathered, the vendor of the unknown device can be concluded by visiting the following:

The first three octets are usually reserved by the vendor.

Appending to Python Path

I discovered this while browser. This is how you can add your directory path to Python:


Your path (i.e. the list of directories Python goes through to search for modules and files) is stored in the path attribute of the sys module. Since path is a list, you can use the append method to add new directories to the path.

For instance, to add the directory /home/me/mypy to the path, just do:

import sys
sys.path.append("/home/me/mypy")
