This is what I get when I try to start MITMf from the Kali NetHunter Menu in Terminal....
Enter Interface: wlan0

Beef-xss is running. Will load autobeef...
/usr/bin/kalimenu: line 469: cd: /opt/MITMf: No such file or directory

If anyone knows how to fix this than please post a response. I checked the directory and there is most definitely not a directory named MITMf in /opt. I went as far to edit the kalimenu file and switch it to use MITMf in /usr/bin or /sbin and changed the command line to just MITMf and not MITMf.py. Also had to change some of the switches because it did not recognize some of them, such as --iface and -w I think it was, but in the end it failed (not at my nexus at the moment, sorry for some of the guessing).
