Wireshark
Wireshark is a network protocol analyzer that allows you to capture and inspect network traffic in real time or from recorded packet files.
It is commonly used for:
Network troubleshooting and performance analysis
Security monitoring and incident investigation
Analyzing TCP, UDP, HTTP, DNS, TLS, and other protocols
Verifying firewall behavior and rule matching (including Palo Alto firewalls)
Wireshark provides detailed visibility into:
Source and destination IP addresses
Port numbers and protocols
Packet timing, size, and retransmissions
Errors, drops, and connection issues
Please note that encrypted traffic (such as HTTPS/TLS) cannot be viewed in plain text, but headers and handshake information can still be analyzed.
Professional one-liner:
Wireshark is a powerful packet analysis tool used to capture, analyze, and troubleshoot network traffic at a detailed protocol level.
