Finale: the final question will be available to a limited number of participants with the most correct answers over the complete course of the quiz.

Mike Canney – Slow FTP

Users are complaining that the FTP is extremely slow to the remote office. We have a 100 Mbps link to the branch. How can we speed up this FTP?

After analyzing THIS (click to download) capture file, choose the best answer to solve this issue:

Phill Shade – Packets Never Lie!

THIS TRACE (click to download) is from a core network segment containing a firewall router, a DNS server, a router to the user’s segment, and a router to the Internet. The Internet router on this segment connects to the company’s ISP via a DSL connection. The company’s local network is not behind a NAT gateway—all internal addresses are visible from the Internet. The complaint is that when the user tries to go to the “hope.edu” website, he cannot connect to it or other websites. All users are having this problem, although the network was operating normally yesterday.

What should be the final step in solving this problem, and what are your recommendations to the Network Admin?

Mike Pennacchi – Poor Wi-Fi Performance

Clients are reporting that Wi-Fi performance is very slow. They can connect to the Internet, but every time they try to download files or watch videos, the load time is very slow.

You have gone out and captured the 802.11 wireless traffic to and from the wireless access point.

Here is the key information about the network:

  • SSID: packetchallenge
  • Passphrase: npsllc02
  • IP Subnet: 192/168.88.0/24

Based on the contents of THIS TRACE FILE (35mb), which of the following is most likely the cause of the poor performance?

Chris Greer – Let’s tinker with QUIC!

QUIC supports several streams of data over a single connection. Each one of these streams has a unique stream ID.

In this QUIC connection, how many of these streams are initiated by the server?

Jasper Bongertz – Modbus protocol

Modbus is a protocol commonly found in industrial environments, but the conversation in THIS .pcap file seems to have a problem.

Why is that?

Sake Blok – Ticketing System

One of your customers is running a ticketing system that periodically performs a mail import from a Microsoft mailbox in the cloud. The customer complained that the import sometimes fails. You captured the network traffic to and from the ticketing system.

Based on the logging of the mail import, you extracted the following session that failed.

Can you tell from THIS .pcapng trace why the import failed?

Vladimir Gerasimov – Single Network Interface

You are capturing and writing data from a single network interface to disk, using custom software. At one moment, you suspect something is wrong with the captured data. To double-check, you perform a test run at 1G line rate with a hardware packet generator.

Looking at THIS trace file (200MB+ zipped), could you detect what is wrong?

This is the final question, only the participants with the most correct answers throughout the entire quiz are eligible to win the grand prize! They will will be notified by email.
