Wireshark Reviews

I'm using the solution for tasks like identifying top talkers and detecting network congestion. I specifically focus on understanding how the network behaves during short bursts, with sampling intervals ranging from milliseconds to tens or hundreds of milliseconds.

I also work with High Frequency Trading (HFT) and use the solution to address issues related to multicast and pinpoint and analyze any gaps in multicast packaging.

One of the features of Wireshark, which is incredibly valuable, is its ability to provide detailed and representative traffic analysis. It allows me to differentiate between protocols like DCP and UDP and even drill down to specifics, such as identifying potential issues caused by a particular destination IP. Additionally, the solution has proven to be a valuable tool for troubleshooting the issues I encounter since my primary focus is on data switching.

Wireshark is one of the best and most popular network management or monitoring tools. Whatever traffic is going from your Internet, you can use the solution to make a plugin into that. You can take a replica of that, and from layer one to layer seven, you can check how the packet is loading and what all information is included in that. Overall, Wireshark is the number one software in the industry that everyone uses for network management.

You can use Wireshark to see the traffic packet format, the IP layers, the fields, and the enabled flags. If you fetch those packets into the TShark version, cybersecurity employees can manipulate and use that packet. Wireshark is powerful to monitor the traffic and check the flags.

There were many use cases of Wireshark. When I was working in Genpact, we were handling more than 850 projects. Wireshark was a great help when we could not open any website or URL given by customers because it was getting blocked.

Wireshark plays a very important part in resolving day-to-day KRAs. Wireshark is a helpful tool for anyone working with a firewall or proxy. When we put up a scan for a particular destination, the product shows the sync at a very granular level. It shows whether the packet has been received or acknowledged by the end server or not. One of the best things about the product is that we can use it to track whether an issue occurred due to the website. Sometimes, the acknowledgment does not happen, and the end server does not accept the request. We get a granular bifurcation of the logs to see at what step it is dropping the connection. Wireshark helps us to understand network traffic.

I use the solution for port mirroring the SPAN ports to send the packet output out of a mirrored port I'm capturing. It helps me determine where the network communication is dropping. Six months ago, I used the tool with a Palo Alto firewall. We had a problem connecting to Azure ExpressRoute. We had to configure QinQ encapsulation. The solution helped us see that the configuration of the network equipment wasn't encapsulating QinQ. So, we knew what the problem was and what we needed to fix.

I like the feature that captures voice calls. It helps me see where the specific latency and jitters happen in the call. If there's a gap in audio, I can see the gap. If there's a digitization as a result of latency, I can see that. I love looking at the packet and seeing Expedited Forwarding or the DSCP tag.

The live capture and offline analysis have been helpful because I can see the real-time capture of the package coming in. The GUI is easy to use. I love that there's a portal feature and an install feature. We can look at multiple interfaces. We can set time frames for capture. I can only capture for ten minutes or only capture a certain amount of packets. I love the ability to see the color codes and change them. I can save the PCAP historical reference. 

I work on WiFi and I am a customer engineer. We use Wireshark to analyze the sniffer captures or tcpdumps. That's the purpose of the solution.

There are very handy filters available in Wireshark.

It’s free and doesn’t cost us anything to use.

The product is simple to implement.

It is a stable solution.

Our primary use case of this solution is for wired or wireless sniffing.

I have found the most valuable feature you can design your sniffer the way you want to. As I said, by default it will have all the legacy features or legacy or advanced features. So apart from that in your device, if you have a particular feature that is enabled, then you can modify it by changing the source code. It provides you with the source code. It is an open source so you can get a source code, you just need to create a plugin or API and point it to that source and you compile it.

I use Wireshark because it's an important tool for us as network engineers to find out the issue, whether it's network-related or application-related. Wireshark is a good tool for deep-dive analysis.

The feature to incorporate Voice over IP (VoIP) incidents into network traffic analysis is valuable. Capturing voice or SIP communication allows for examination of interactions between SIP clients and SIP servers. 

This helps the team investigate or analyze issues related to call center servers and operators. It's a tool for communication server functionality. These tools help the team achieve its objective of improving services by detecting issues.

We're using an internal Wi-Fi card in the laptop, so we configure that particular wireless interface into monitoring mode, configure the channel, and use Wireshark for that specific interface. We can capture the packets and activities on that channel, analyze the packets for poor connections, etc.

What's best about Wireshark is that it doesn't require installation. It supports cards and monitoring permissions and is sufficient for appending and capturing activities. You won't need to install other tools to use Wireshark, so this saves you time. You can capture packets at any time from your laptop through Wireshark.
