bettercap missing local to local traffic

issue i ran into

had 3 virtualbox vms
1.) linux running python SimpleHTTPServer, simulates a website, network set to "internal network"
2.) windows accessing the linux website in #1 above, simulates the victim, network set to "internal network"
3.) kali running bettercap, arp.spoof.targets = linux server #1 above and windows #2 above, will do MiTM (man-in-the-middle) against the 2 systems above, network set to "internal network"

Issue I ran into is that with ettercap (no 'b') it worked great, I could see the traffic going from windows box to linux web server ... BUT with bettercap the arp spoof seemed to work but the traffic was nowhere to be found when using tools like "net.sniff" or "https.proxy" on bettercap.

Root Cause:
    By default ettercap (no 'b') captures all traffic (local & external)
    By default bettercap only captures external traffic & ignores local to local traffic

    set arp.spoof.internal true
    set net.sniff.local true

The enables capture of internal traffic and now I started seeing it!

  1. I want to thank Dr Emu a very powerful spell caster who help me to bring my husband back to me, few month ago i have a serious problem with my husband, to the extend that he left the house, and he started dating another woman and he stayed with the woman, i tried all i can to bring him back, but all my effort was useless until the day my friend came to my house and i told her every thing that had happened between me and my husband, then she told me of a powerful spell caster who help her when she was in the same problem I then contact Dr Emu and told him every thing and he told me not to worry my self again that my husband will come back to me after he has cast a spell on him, i thought it was a joke, after he had finish casting the spell, he told me that he had just finish casting the spell, to my greatest surprise within 48 hours, my husband really came back begging me to forgive him, if you need his help you can contact him with via email: or add him up on his whatsapp +2347012841542 is willing to help any body that need his help.
