Amazing tool that captures packets and disassembles them. Allows you to click an interactive tree that represents Ethernet, TCP/IP and application layer like HTTP.
Start capture immediately from CLI, capture packets to/from 192.168.1.102:
sudo wireshark -f 'host 192.168.1.102' -k
Capture by instead:
sudo wireshark -f http -k
sudo wireshark -f icmp -k
Filter by both protocol and host:
sudo wireshark -f 'host 192.168.1.102 and icmp' -k
For application layer capture filtering, the best you can do is by port:
sudo wireshark -f 'tcp port 80'
There is an http filter but only for as a wireshark display filter
Sample usage:
sudo tshark -f 'host 192.168.1.102
This produces simple one liners for each request.
What you likely want is the -V option which fully disassembles each frame much as you can do in the GUI Wireshark:
sudo tshark -V -f 'host 192.168.1.102
