Pcap Analyzer FAQs

Question 1

What is Pcap Analyzer and its primary function?

Accepted Answer

Pcap Analyzer automates complex PCAP analysis and network troubleshooting by encapsulating common Wireshark workflows into structured tools. This allows agents and scripts to automate tasks like display filtering, data extraction, and session tracing efficiently.

Question 2

How does Pcap Analyzer mimic Wireshark functionalities?

Accepted Answer

It converts Wireshark-like operations into API-driven tools, including retrieving frame numbers by display filters, generating time-series tables, drilling down into specific frames, automating session tracing (e.g., SIP Call-ID), and exporting packet lists.

Question 3

Does Pcap Analyzer require any external dependencies to run?

Accepted Answer

Yes, Pcap Analyzer relies on `tshark` (the command-line network protocol analyzer that comes with Wireshark) for its core functionality. `capinfos` is also recommended for PCAP file summaries.

Question 4

What specific network troubleshooting scenarios does Pcap Analyzer support?

Accepted Answer

It excels in troubleshooting 5G core/RAN signaling (e.g., NGAP, PFCP), IMS/SIP call issues (SIP, Diameter, HTTP2), and QoS/policy problems, providing a programmatic approach to analyzing these intricate protocols.

Question 5

Can Pcap Analyzer trace specific network sessions or calls across multiple protocols?

Accepted Answer

Absolutely. Its `pcap_follow` tool can automatically extract and apply follow filters (such as SIP Call-ID, Diameter Session-Id, or HTTP2 streamid) from a selected frame, enabling comprehensive tracing of entire sessions or calls.
