You can enter filter condition such as ip.address == 192.168.0.1 to display all packet related to 192.168.0.1.  Please refer to the question below and write an appropriate filter condition.

• Find all packets with HTTP respond code 200
• Attacker tries to download the malicious file from www.ethereal.com. Write down the filter condition to identify the http host. (Hint: refer to diagram 1a highlighted line 96 in wireshark
