DNS spoofing in Kali Linux

I'm trying to learn some stuff about DNSspoofing, but it didn't work well for me. Here's what i have done. step 1 : turn my NIC into promisc mode using the following command ifconfig wlan0 promisc step 2 : make a hosts file for dnsspoof named : /usr/share/dsniff/dnsspoof.hosts (this is suggested in the man page of dnsspoof ) here's what's i typed inside the file github.com 192.168.1.102 *.github.com 192.168.1.102 www.github.com 192.168.1.102 step 3: run dnsspod with the following command dnsspoof -i wlan0 -f /usr/share/dsniff/dnsspoof.hosts then i get this output : everything seems okay to me, but whenever i tried visiting github from my machine or other machine in my network, it didn't go to the given adress 192.168.1.102
