TAP into Technology

Debugging and Troubleshooting Performance Issues with the FieldTAP

With the launch of Garland Technology’s new FieldTAP, one of the perks I can boast about is getting to test and use new technology. Especially working remotely, I was excited to have such a versatile TAP to add to my gear. With the new circumstance we all find ourselves in, this came in handy as we are finding an influx of remote performance issues around the industry and the need to quickly solve any issues. Debugging and troubleshooting performance and operational issues in a Wi-Fi Access Point or VoIP phone deployment often involves taking packet captures of the device’s network traffic using Wireshark.

How to Troubleshoot the Network Part 2: Solving Network Forensics Problems

on 5/7/20 8:00 AM By | Todd Cain | 0 Comments | Network Security Network Visibility/Monitoring Wireshark Troubleshooting

Part 1 in this two-part series on how to troubleshoot the network focused on the most common challenges you’ll face—connectivity, performance, and latency troubleshooting scenarios. And in a perfect world, these would be the most difficult network problems you’d ever face. But the reality is that troubleshooting has grown increasingly complex over the last decade. Now, network speeds are faster than ever, you’re processing exponentially more data, and cyber threats have become increasingly sophisticated. As a result, it’s harder than ever to find root causes and solutions to network problems.

How to Troubleshoot the Network Part 1: Common Problems and the Tools to Solve Them

The availability of your network and IT services can make or break business performance. A full-blown outage costs 86% of companies more than $300,000 per hour with 34% saying the costs would exceed $1 million per hour. But it’s not just outages that come with high costs. Slow performance and frequent brownouts will also lead to significant damages. While IT decision makers say that 51% of outages are avoidable with proper monitoring, we have to recognize that troubleshooting is a fact of life. Being able to do so effectively and efficiently will keep your business running smoothly even when issues arise. This is Part 1 in a two-part series explaining how to troubleshoot your network. Here, we’ll talk about how to troubleshoot the most common network issues and the tools needed to do so. And in Part Two, we’ll talk about how to troubleshoot network forensics issues.

Group Packet Competition at Sharkfest Europe 2017

Sharkfest Europe is back for a second year, and Garland Technology is continuing our support of the Wireshark community by sponsoring this year’s Group Packet Competition. While Sharkfest is well established in the US as the premier educational conference for Wireshark users to share knowledge, experiences, and best practices, over in Europe, the conference is still in its early years. At Sharkfest, the Group Packet Competition is designed to bring teams of Wireshark users together. Each team is given a group of trace files and a sheet of questions. Then, they are challenged to race against the clock to find the answers, often using areas of Wireshark they aren’t familiar with. The Competition is a great way to teach users of all different skill levels new tricks about the analyzer in a fun environment.

Packet Challenge at Sharkfest - A Great Way to Test Your Skills!

This year at Sharkfest, Garland Technology is sponsoring the group packet challenge (Thank you!). As packet-heads, we all enjoy digging through trace files and finding the hidden gems that lead to resolving a problem. If most of our capturing experience is from a single network or enterprise, it can be hard to grow in new areas and pick up new tricks in packet analysis. Sharkfest is an excellent way to hone our skills and bring our art of analysis to a new level. The group packet challenge at Sharkfest is designed to bring together Wireshark users from all skill levels in a timed team event. Participants are given several trace files and a question sheet, then as a team they race to find the answers. Typically, the packet challenge will require them to use areas of Wireshark that they may not be as familiar with, which can teach them new things about the analyzer in a fun setting.

Are my Packets Lying? - 4 Things to Look for in Packet Traces

Packets don’t lie – well, most of the time. They tell the truth unless they have been captured incorrectly. In those cases, packets can tell bold-faced lies. When digging through trace files, we can come upon symptoms in the packets that may raise an eyebrow. These are events that look strange on the surface and may even divert our troubleshooting focus for a time. In fact, some of these issues have misdirected engineers for hours, if not days, causing them to chase down issues and events that simply did not exist on the wire.
