You can find the source code as well as a stand-alone executable on GitHub. The final aim is to combine the interface status and mac address table output and map all the mac addresses against an interface in one excel cell using openpyxl. However, even with Python, this can be easily done with just the standard library.įor portability, I recommend throwing the script into PyInstaller to create a stand-alone executable. The smartest way is probably a PowerShell script. I have used Python to quickly get the script done, however this is possible in any language of your choice. Automation using Python: Since it is not possible for us to manually change the MAC Address every. We can see the list of interfaces using: ifconfig.
To review, open the file in an editor that reveals hidden Unicode characters. After installing this package, we can change the MAC Address using: sudo ifconfigThis file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. The usual workaround is setting the first octet of the address to 02, e.g. The python module netaddr can help you work with MAC addresses.

Some WiFi network adapters do not accept changing the MAC address to an arbitrary different (valid) address. In my experience, my macbook pro MAC address can be changed with the bash command listed in the file for wifi (sudo ifconfig en1 ether addr), but it will not let me change it to any arbitrary address I want, just some of them, including addresses that start with aa:rest, ab:rest, etc., which is what I usually go for. To undo the change, the created key is deleted. Then set it to the value of the desired MAC address, e.g. In principle its just creating the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\\\ NetworkAddress This means you will always see x2, 圆, xA, or 圎 at the beginning of a MAC address generated by randmac. the optional -f argument will return a random 12-digit MAC address that can be identified by the locally administrated address (LAA) format.

The scripts basic functionalityįor more details have a look at the previous blog post. a utility that generates 12-digit mac addresses either the NIC portion or full 12-digit MAC. Nu tiu cum s generez adrese MAC aleatorii.

Wikipedia has a good one.After writing the previous blog post about manually changing the MAC address of a Windows system, I decided to create a small Python script which would ease up the whole process. n scopul crerii de maini virtuale n bloc, trebuie s creez un generator de adrese MAC aleatorii n Python. MAC addresses aren't that complicated, so you should probably also just have a look at the definition.
This OUI value ends up in the first 3 bytes (or just the top 22 bits, really). See this link for the global registry of OUI values. MAC addresses in this category are centrally registered with the IEEE, and you should have a unique OUI (Organizationally Unique Identifier) issued to you by the IEEE. If the MAC address is not locally administered, it means it is supposed to be "globally unique".

The bottom two bits of the top byte (0x02) give you a locally administered unicast address, which is probably what you want if you are hitting stackoverflow for how to generate this. Next, we will look at another function within the secrets module choice() and apply Python list comprehension. The resulting hex string will be of length n 2. Firstly, from Python’s secrets module, we will use the function tokenhex(n), where n specifies the number of bytes. This gives you a unicast MAC address that is 100% safe to use in your environment, and isn't trampling on anyone's registered MAC address space. Today I will go over four methods to generate a random hex string in Python. Let's change to a specified MAC address now: python macaddresschangerlinux.py wlan0 -m 00:FA:CE:DE:AD:00. My interface name is wlan0, and I've chosen -r to randomize a MAC address. Or, if you want to do this in a unix'y shell, this works on many: printf '02:00:00:%02X:%02X:%02X\n' $((RANDOM%256)) $((RANDOM%256)) $((RANDOM%256)) python macaddresschangerlinux.py wlan0 -r. For anyone wanting to generate their own MAC addresses (a good example is for VM NICs), you probably just want this: "02:00:00:%02x:%02x:%02x" % (random.randint(0, 255), (Send thousands of Ether packets with random MAC addresses in each packet) - /usr/bin/env python from scapy.all import Ether, IP, TCP, RandIP, RandMAC, sendp '''Filling packetlist with ten thousand random Ethernet packets CAM overflow attacks need to be super fast.
