I was running the bypass.py script and received this error.

[*] Found the below IPv6 addresses
Traceback (most recent call last):

I edited the code according to Python3. You can access the current version via the repo below:

Hello,

Its seems to be a great tool which will save a lot of time during pentest.
But, i have an issue run this tool on Kali:

python bypass.py -i eth0 -r 192.168.2.0/24
Traceback (most recent call last):
  File "bypass.py", line 10, in <module>
    nm = nmap.PortScanner()
AttributeError: 'module' object has no attribute 'PortScanner'

Thank you!

The interface value is not passed to the arp-scan command.

Change line 228 to

cmd="/usr/sbin/arp-scan -I "+interfaceNo+" "+targetIP

Seems to work then
