Python-generate_mac

Python library for working with Ethernet MAC addresses. Functions for generating transforming and testing MAC addresses.

Uses Wireshark's manuf, or s similarly formated file as input for specific Vendor ID(VID) bytes, for creating more

Supported functions:

Generate

total_random() - Procedurely generated MAC address, using random function.

vid_file_random(file) - uses random line from wireshark's manuf file

vid_file_vendor(file, vendor name, desc=optional) - specify a vendor name, uses wireshark's manuf file instead of being completely random. May optionally specify desc, which searches description within the vendor field

vid_provided(vid bytes) - specify the VID bytes when calling the function. Random device bytes will be generated.

Test

list_vendors(file) - return a python set{} of uniqe valid vendors, from a wireshark manuf file

is_mac_address(mac) - Takes a string, and checks if it is a valid Ethernet MAC address. returns True or False(bool type)

Transform

get_vid_bytes(mac) - Returns the vendor bytes(first three) from a MAC address.

another_same_vid(mac) - Generates another MAC with diffrent device bytes with same vendor bytes as input

Usage

Import and set up an object.

from generate_mac import generate_mac

Procedurely generated Vendor and Host bytes. Checks for broadcast bit

generate_mac.total_random()
'7E:CD:60:1E:AC:6E'

Read Vendor bytes from random line in a file. This has to be formated the same as wireshark's manuf file.

generate_mac.vid_file_random('/usr/share/wireshark/manuf')
'70:B3:D5:C5:40:49'

Read from a manuf file like above, but find Vendor bytes belonging to a specific vendor, by name.

generate_mac.vid_file_vendor('/usr/share/wireshark/manuf',"Motorola")
'40:88:05:4F:CE:82'

OPTIONAL: this can also now search the description field

generate_mac.vid_file_vendor('/usr/share/wireshark/manuf',"Motorola","BSG")
'00:24:37:5C:3A:8B'

Provide the vendor bytes in a string. Generate Host bytes only

generate_mac.vid_provided('00:06:8C')
'00:06:8C:35:5E:C4'

List valid vendor options as a list.

generate_mac.list_vendors('/usr/share/wireshark/manuf')
['Vendor1','Vendor2','etc']

Check if a MAC address is valid. returns a Bool(True,False)

generate_mac.is_mac_address('00:06:8C:35:5E:C4')
True

Get the VID bytes from a MAC address

generate_mac.get_vid_bytes('00:06:8C:35:5E:C4')
'00:06:8C'

Generate another MAC from the same VID bytes as current MAC

generate_mac.another_same_vid('00:06:8C:35:5E:C4')
'00:06:8C:3D:C2:F2'
