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.

It's a tool that we use to capture the network and if there is any lag or if there are packet drops.

It's a very useful tool. We are using it to monitor any network depreciation. For example, suppose there's a call going on between two IP phones and one person says that I cannot hear you. There's definitely something wrong. The RTP is getting dropped, and the packets are getting dropped. We need to capture the live call or if there are any prerecord calls for this particular time period. We go ahead and use this tool to find out whether the packets dropped when a packet is dropped and what caused the audio issue or video issue. We actually use it to understand any network issues.

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'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.

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.

The primary purpose of Wireshark is to monitor network communications. For example, if we need to track our target in order to exploit it, or to understand our use cases, we can use Wireshark for both internal and external penetration testing. We can use Wireshark to capture communication from any IP, and if there is no encryption, we can also use it to retrieve client passwords. This is the main function of the solution.

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

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.

I use Wireshark in my company for in-depth troubleshooting, especially when you need to look at individual packets.

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.

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.

I use Wireshark to analyze packets, especially network packets.

We primarily use Wireshark for troubleshooting critical issues in our network, retrieving packet headers using packet capture, and for creating custom apps. There are six people on our team and we all use Wireshark on our devices. 

We primarily use the solution for reading packet captures. It's like a packet analyzer, packet capture. 

I'm just reading some packets and looking for interesting tracking. That's all.

We use Wireshark to check the network traffic, and if there's any network problem or issue, we can check it through the tool. We also use Wireshark during analysis, to check if there's any network connectivity or attempts from the malware to communicate with the C&C server. We use the tool for further analysis and investigation.

When we can see in the customer environment that traffic is getting blocked; suppose we have a VPN channel, and when the VPN channel is up but the traffic is not running through it, we use Wireshark to recapture the channel. We check whether the PPP handshake is ongoing or not. The acknowledgment team posts this packet, and after that, the PPP handshake is ongoing or not. 

So these are the things that we check by filtering out the things and based upon that, we get support. Because in five to six seconds, there are more than a thousand packets. So we have to filter out and check on which speed it is getting dropped. For that reason, we are using Wireshark. I am using it just for troubleshooting purposes.

I have been using Wireshark for the packet tracing, and it has helped me to find out whatever site, et cetera. It is useful, basically capturing packets of data on the network.

It helps us to identify the source the packet is originating from and it also helps us to know about the return time of the packet from when the packet is going from our computer to when it reaches the destination IP address. It helps diagnose internet connectivity problems and also helps us to know what the website data consists of and how much data is in the website.

And it also helps us to know about the various protocols which are being utilized when we are connecting to the internet. We also get to know what bites, et cetera, are present in our data or if there is any malicious packet that is not supposed to come in. Based on it, we can configure our firewall. 

I use Wireshark for DT inspection of several protocols and choose different color patterns to make it easy to see the various protocols. It also involves live analysis because I can see the live analysis on the Internet. The main task of Wireshark is to inspect the throttle and live data, and it's doing them.

Wireshark is a network analyzer used to capture traffic. It's used to analyze patterns in the network to check for any malicious traffic generated from devices or endpoints.

I use the solution to analyze packet captures that I receive from customers. It can also be used for troubleshooting networking issues.

We use this solution for troubleshooting network issues.

Wireshark is a tool for ARP scanning. I started using Wireshark back when I had a YouTube channel. It was mostly a security channel to show people how easily you can get hacked and how to hack. I was doing some research for my videos. I didn't know much about security, but I was interested in it, and Wireshark was one of the software solutions that kept popping up.

I watched some videos on how to use it and incorporated that into some of my videos. When I discovered something funny on my network a couple of years later, I decided to reinstall Wireshark to run some scans and found the culprit.

 It's all on-premises. Here in South Africa, a couple of companies have migrated to the cloud, but that's quite expensive for many of them. It's much easier and cheaper to buy a server and host everything locally. The only thing they keep in the cloud is email because on-premise email is just horrible. Most of my clients are on-premises. One or two has Azure or something like that.

I mainly use Wireshark for knowledge purposes, debugging, and to view what's going on in the network.

This solution is deployed on-premises.

Wireshark is a packet analysis tool. We check Wireshark when we don't know what's causing an issue.  The network packets never lie. Three people on my company's network team use Wireshark. 

I mainly use Wireshark to look at traffic conditions when something is getting stopped in our network.

There are multiple use cases for Wireshark. One of the primary use cases is capturing the customer's network traffic. When an issue occurs on the customer's network, we take packet captures to analyze and decode the streams that were active during the time of the incident. 

Additionally, we use Wireshark to replay packet streams. This helps us troubleshoot issues that may not be readily observable on the live network. With the packet capture in hand, we can analyze the decoded packets and identify the protocols involved and the specific nature of the issue that occurred.

Our primary use case for the solution is to see the over-the-air packets, the data transmission, and the wifi connection.

Wireshark can be used to troubleshoot network issues, but also to baseline applications. When you know what an app does when there is no issue at hand, you will be better able to spot the problem when there is an issue. Everything that happens on the network can be analysed with Wireshark. However, the tool is as good as the person using it. You need TCP/IP knowledge to be able to use a tool like this. The more you know about packets on the wire, the better you can use this tool.

I use it for network investigation, I even have a patent for the simplification of Protocol Analysis. I have used Wireshark many times to troubleshoot network situations and problems. The patent solved the problem of troubleshooting where you needed to know the direction and course a packet takes in the network which helps with the ability to know where problems lie in the network. We developed the system to actually troubleshoot an entire network through the use of network probes, which acted as smaller protocol analyzers.

I used it for a couple of school projects last semester. We basically had to emulate how to capture packets in transit in a network. After capturing those packets, we analyzed them. We also had to break down email messages and dig out pictures inside email messages.

It was deployed through a cloud. They had set up a subscription for a class VM.

I basically use Wireshark for network troubleshooting.

I use the solution to monitor our company network. It is installed on my PC and I pull data from our local server to conduct monitoring.

We use Wireshark as a tool for network troubleshooting when we need to verify something directly. It is not used every day.

As an example, FortiGate, Wireshark can also export, we can pick up a file, process it, and apply it. Some tools allow us to take, capture, define and export to Wireshark, so we are able to analyze in great detail.

It is utilized for forensic work, with full packet capture.
