[AWK] Ekstrak Pita Lebar TCPDump

AWK is really awesome script ! almost of my PhD code rely on AWK. At This time, I wanna share my snippet to extract uplink adn downlink bandwith for certain port in localhost. In this case, suppose that we will investigate port 8000, thus I put regex


ok, let’s play TCPDUMP now.

tcpdump -l -i lo port 8000 -nNqttf > tcpdump

Here is the following awk code to parse each line of tcpdump that are stored in tcpdump file

cat tcpdump | awk -F " " '{
if($5 ~ /(.*)8000:$/)
print uplink
print downlink

Above code will produce the number of uplink and downlink in bytes.
