I am trying to do a packet capture for a computer in my home wifi network on my local machine. I am using ubuntu on my local machine.
These are the steps I have taken
sudo ifconfig <network_interface> down
sudo iwconfig <network_interface> mode monitor
sudo ifconfig <network_interface> up
However when I do tcpdump host <target_machine_ip> and try to run some curl command on the target machine I don't see any activity recorded on my local machine.
Additionally I have also tried running ip link set eth1 promisc on and then running the above exercise of running curl command on the target machine but I still don't see any activity on my local machine. Please advise what am I missing.
Thanks in advance!
