Sniffing and displaying TCP packets in UTF-8

Question

I am trying to use tcpdump to display the content of tcp packets flowing on my network. I have something like:

tcpdump -i wlan0 -l -A

The -A op

Answer 1

tcpdump -i wlan0 -w packet.ppp

This command stores the packets in packet.ppp

After that open it in wireshark

wireshark packet.ppp

right click on the packet and then select Follow tcp packet

Then you can have available different formats to view the data in wireshark.
