Wireshark

We found a bug in the network of our organization due to an intermittent issue thanks to Wireshark analysis. This tool has never let me down all these 02 years. Packet capturing and analyzing the traffic flow are the best usage I take out of Wireshark and I have been able to rely on this always.

Wireshark is made up of advanced features for capturing packets and analyzing network protocols and can be used to capture different network cards and technologies such as wifi and BlueTooth. We recommend the use of this tool by all IT professionals as it is fundamental for the security of the network and identifies everything that is traveling on the network by protocol, ports, and IPs and then analyzes it to solve problems and security flaws with the internet.

If someone needs to deep dive into the network to check for causes of latency and slow speed cropping up when people get working, they definitely need Wireshark. I have used it in an office of 25 users, with each having a computer on the wired network and a mobile phone on the WiFi. I use Wireshark to check the network status and Meraki & Umbrella to implement policies.

It allows us to follow the trace of the TCP stream packets, we can see everything related to said packet, the before and after, being able to apply custom filters to them without losing the flow.

When I want to see what type of traffic is leaving a workstation, Wireshark is second to none. However, if I want to see images, it then becomes much more difficult to render the images.

Wireshark is well suited for network troubleshooting scenarios, such as when setting up a VPN site to site tunnel and having issues connecting, whether the connection is failing at the outset, or if the failure is occurring several steps in, e.g. at the second IKE proposal etc. It provides excellent insight into issues like this. Another example is when VPN users fail to connect via VPN client, so the troubleshooting steps would be similar.

On different occasions we have had issues with our Microwave router Gui, where it can ping the ip but can't access the web interface. We used Wireshark to see the type of traffic that is being sent and received that allows us to eliminate certain problems and narrow down to the solution.

We had an issue where a user could not connect to an external system. The vendor was blaming our network however it was working fine for everyone else. Turns out there was an issue on the vendors side where it was refusing connection due to some strange settings they had on their end. Wireshark helped prove this wasn't on our end.

1. IPS / IDS Packet analysis
2. Network troubleshooting by reviewing the packets to determine the issue
3. Monitoring interfaces to identify missing / extra packets
4. Analyzing packet structure of required protocol

When you need to get to the bottom of a specific issue, usually used as a last resort when the usuall diagnosics have failed. You do required physical access to switches / devices to conduct tests. Needing to configure mirror ports is not allways obtainable with hardware that you have deployed.

Any network traffic can be dissected and analyzed. This will help greatly in in finding the problem with the application traffic. I have worked on database upgrade and we had connection drop while loading the database data in batch from application server. With Wireshark was able to identify the handshake algorithm used in communications and was able to find the comparability over the windows versions.

Wireshark is a must-have tool for an IT manager, engineer, support specialist, etc. If you manage a network, you will, at some point, run into an issue where you need to see what is actually happening inside those packets. Wireshark gives you that opportunity and will be amazingly helpful at reaching a solution.

Analyze Traffic across the Network. You can create your own filters with specific color codes to track the traffic of interest. The packet capture provides you all the details including the source, destination, protocol, ports and helps troubleshoot Network and Security related issues. This tool can also be used for Network and Security audits and Network Scans to monitor any rogue traffic.

Wireshark is great for forensic analysis of network traffic. If users are having issues, or if we are seeing connectivity issues for VPN users, or if there is suspicion of unexpected or unwanted traffic on the network, Wireshark can help to find the source of any/all of these. With filtering by key values, protocols, or IPs, this can be a very powerful tool.

Wireshark is excellent for analyzing traffic across your computer or network. When there are communication issues between software, scripts, router, and switches, Wireshark will help troubleshoot the issue at hand. Wireshark is great at analyzing a wide variety of protocols and packets that are transferred. However, there is a really steep learning curve bunched up with an interface that could be modernized.

I don't know of any other tool that works as well as Wireshark for packet capture an inspection. It's extremely easy to get up and running, and even with little to no knowledge of how to use the tool, you can be looking at all the traffic coming off a network interface.

Wireshark is great for enterprise networks with large amounts of data traversing the network that need a way to filter and inspect specific traffic by specific parameters (i.e. destination / source IP address, host, or type). There are use-cases for smaller environments, but the amount of time needed to learn how to effectively use the tool may not be beneficial for home / small office users.

I'd always recommend Wireshark to colleagues if they're looking to analyze network traffic. They're a well know, trusted market leader in this space. I'd recommend that they watch a video demo on the product to get a better understanding of how to use it most effectively but if they were to commit some time to explore the product

If you need to analyze packet data across your network and want the low-level details, Wireshark is perfect for the job. It records the necessary data and presents it in a way that's relatively easy to read, analyze, and understand. It's got a ton of features (more than most people will ever need). However, if you're simply interested in HTTP traffic, I believe Fiddler is a slightly better choice, as it is more explicitly geared towards the HTTP protocol.

It is invaluable for capturing and analyzing network traffic and identifying issues with devices that are either malfunctioning, or possibly even set up as rogue devices on a network. Using the data from a packet analysis combined with logs and MAC tables from various network devices, it can be used to find specifically where a device might be located. It's not a "set it and forget it" application, but it is well suited for on-the-spot analysis.

Wireshark is a great tool to use after general network troubleshooting has taken place; checking subnet mask, default gateway, route table, etc. It can help identify breaks or hiccups in network communication, and narrow down where further investigation should be focused. It is not a good tool to use for general troubleshooting, you need to have a core knowledge of networking to find the tool valuable.

I use Wireshark nearly every day, it's the most important tool in my daily work as a network engineer to troubleshoot the real network problem in the production network. It helps me to look into the problematic protocol scenarios in the packet layer to understand where is the problem and how to fix.

Wireshark is well suited for scenarios in which the technical difficulties are being faced. A lot of times we are not aware of how computers actually talk with each other. With Wireshark, you can learn this topic in depth and help yourself and your colleagues in case anyone is facing any sort of networking related problems. Many people just use the computer system for basic tasks and often tend to get stuck on simple things like if the system is not able to retrieve the IP from the router. After you learn these concepts you can easily solve these problems. Wireshark is a bit of a technical software program and only intended for people who have a basic understanding/ background of computers. If not, this software might end up giving you a lot of information which will be really tough for you to understand. So I would recommend if you want to use this software and are interested in the concepts as mentioned before/ above, go through a quick course on computer networking concepts and you shall be good to start exploring Wireshark.

Wireshark is nicely laid out, integrates with Snort, Splunk, etc, and overall is great software. I am moving into a Critical Informatics role, or as a security analyst after graduation, and Wireshark will be one of my most solid backbone tools in pen testing. So using it on an educational platform has set me up for success once I get into a real-time environment.

Wireshark is best suited to capturing and analyzing network traffic data. It is not an intrusion detection system (IDS), or a honeypot, or any real-time security tool. Offline analysis is where Wireshark shines. Take a capture using it or some other tool and load it into Wireshark for extensive analysis. Wireshark is great for forensic analysis of network traffic. You can find malformed packets, attack signatures, suspicious traffic, etc. Nothing gets by Wireshark.
