TCPDUMP FILTER

# don't resolve ip addresses
sudo tcpdump -n

# filter on ip.identification == 0x01a4 (420)
sudo tcpdump ip[4:2] == 0x01a4

# filter on ip.dst_addr == 0x08080808
sudo tcpdump ip[16:4] == 0x08080808

# filter on ip.dst_addr == 0x08080808
sudo tcpdump ip[16:4] == 0x08080808

# filter on icmp
sudo tcpdump icmp

# filter by interface
sudo tcpdump -i wlan0

# show raw packet in hex
sudo tcpdump -x

# all together
sudo tcpdump -xni wlan0 ip[4:2] == 0x01a4 or icmp

TODO

1. fix flag at the end pop unknown host
2. fix getting weird result in ft_i4toh
3. sort ip on prob, so different ip could be spotted more easily
