For those of you that know me, you know that every time I make a post in the forum sections, I usually complain about my MITM attack not working. Well guess what...I fixed it! I didn't even have to buy a wireless adapter for my virtual machine. I read forums for months, and I found one that helped me solve my problem. Apparently, arpspoofing is having trouble processing requests with the virtual mac address, so all I did was use macchanger to change my mac address to that of my host.
macchanger eth0 -m xx:xx:xx:xx:xx:xx
Thank you all so much for your help. :D
