Packet Sniffing may sound like a malicious activity at first glance, but it is actually an ethical way to analyze the network, and diagnose any network-related problems. Packet Sniffing tools are used by network technicians for such diagnostic processes. Having said this, there are an equal number of incidences where packet sniffing is used by hackers for malicious activities such as collecting passwords and spying on user traffic.
Here, we are not going to talk about packet sniffing attacks, but some free packet sniffing tools that can be effectively used to diagnose network problems and resolve the issues. Before we present you three packet sniffing tools for Windows, let’s look at how packet sniffing tools work in general.How Packet Sniffing tools work
There are different types of packet sniffers. Some packet sniffers are used only for detecting hardware-related problems. Other packet sniffing tools are actually some software apps that run on the host computers.
The packet sniffing tools intercept and log network traffic. The tools ‘view’ the network using a wireless or wired network interface. The packet sniffing tool needs to have access to this interface on its host computer. If it is a wired network, a packet sniffing tool can capture the data which totally depends on the network’s structure.
The network structure might let the packet sniffer tool view traffic on the entire network or it can let it view only a small segment of it. If it’s a wireless network, packet sniffing tools can capture one channel using the wireless interface. If the host computer has multiple wireless interfaces, then the packet sniffer can capture multiple channels.
The sniffing tool then analyzes the captured raw packet data. The analysis is converted by the sniffing tool into a readable format. This analysis is nothing but the conversation between nodes on the network. This very information is helpful for the network technicians to locate the fault.

If you also wish to analyze your network, here are three free packet sniffing tools for Windows.1. WireShark Packet Sniffer
Wireshark is one of the popular free packet sniffing tools for Windows. This tool can give you an ability to see what’s happening on your network at a microscopic level. Some of the important features of this tool are as follows:
Deep inspection of hundreds of protocols, with more being added all the time
Live capture and offline analysis
Standard three-pane packet browser
Apart from Windows, this tool can run on other operating systems such as Linux, OS X, Solaris, FreeBSD, NetBSD, and many others
Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
The most powerful display filters in the industry
Rich VoIP analysis
Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
Coloring rules can be applied to the packet list for quick, intuitive analysis
Output can be exported to XML, PostScript®, CSV, or plain text
You can try this tool by downloading it from its website.2. SmartSniff
SmartSniff is yet another free packet sniffing tool that allows you to capture TCP/IP packets that pass through your network adapter and view the captured data as sequence of conversations between clients and servers. With the help of this network monitoring utility, you can view the TCP/IP conversations in ASCII mode or as hex dump.
SmartSniff provides 3 methods for capturing TCP/IP packets:
Raw Sockets (Only for Windows 2000/XP or greater): This method allows you to capture TCP/IP packets on your network without installing a capture driver. However, this method has some limitations and problems.
WinPcap Capture Driver: This particular method lets you to capture TCP/IP packets on all Windows operating systems.
Microsoft Network Monitor Driver (Only for Windows 2000/XP/2003): Microsoft provides a free capture driver under Windows 2000/XP/2003 that can be used by SmartSniff. However, this driver needs to be installed manually.
If you wish to try this packet sniffing tool, download it from here.3. Microsoft Message Analyzer
Microsoft Message Analyzer is the successor to Microsoft Network Monitor. It is helpful in capturing, displaying, and analyzing protocol messaging traffic and other system messages. It is not only an effective tool for troubleshooting network issues, but for testing and verifying protocol implementations as well.

If there is one sentence, which summarizes the essence of learning data science, it is this:
The best way to learn data science is to apply data science.
If you are a beginner, you improve tremendously with each new project you undertake. If you are an experienced data science professional, you already know what I am talking about.
If you think that the situation above applies to you – Don’t worry! you are just at the right place. This article will provide you a list of websites / resources from which you can use data to do your own (pet) projects or even create your own products.How can you use these sources?
There is no end to how you can use these data sources. The application and usage is only limited by your creativity and application.
The simplest way to use them is to create data stories and publishing them over web. This would not only improve your data and visualization skills, but also improve your structured thinking.
On the other hand, if you are thinking / working on a data based product, these datasets could add power to your product by providing additional / new input data.
So, go ahead, work on these projects and share them with the larger world to showcase your data prowess!
I have divided these sources in various sections to help you categorize data sources based on application. We start with simple, generic and easy to handle datasets and then move to huge / industry relevant datasets. We then provide links to dataset for specific purpose – Text Mining, Image classification, Recommendation engine etc. This should provide you a holistic list of data resources.Simple & Generic datasets to get you started
chúng tôi – This is the home of the U.S. Government’s open data. The site contains more than 190,000 data points at time of publishing. These datasets vary from data about climate, education, energy, Finance and many more areas.
chúng tôi – This is the home of the Indian Government’s open data. Find data by various industries, climate, health care etc. You can check out a few visualizations for inspiration here. Depending on your country of residence, you can also follow similar websites from a few other websites – check them out.
World Bank – The open data from the World bank. The platform provides several tools like Open Data Catalog, world development indices, education indices etc.
RBI – Data available from the Reserve Bank of India. This includes several metrics on money market operations, balance of payments, use of banking and several products. A must go to site, if you come from BFSI domain in India.
Five Thirty Eight Datasets – Here is a link to datasets used by Five Thirty Eight in their stories. Each dataset includes the data, a dictionary explaining the data and the link to the story carried out by Five Thirty Eight. If you want to learn how to create data stories, it can’t get better than this.Huge Datasets – things are getting serious now!
Amazon Web Services (AWS) datasets – Amazon provides a few big datasets, which can be used on their platform or on your local computers. You can also analyze the data in the cloud using EC2 and Hadoop via EMR. Popular datasets on Amazon include full Enron email dataset, Google Books n-grams, NASA NEX datasets, Million Songs dataset and many more. More information can be found here.
A few months back, Google Research Group released YouTube labeled dataset, which consists of 8 million YouTube video IDs and associated labels from 4800 visual entities. It comes with pre-computed, state-of-the-art vision features from billions of frames.Datasets for predictive modeling & machine learning:
UCI Machine Learning Repository – UCI Machine Learning Repository is clearly the most famous data repository. It is usually the first place to go, if you are looking for datasets related to machine learning repositories. The datasets include a diverse range of datasets from popular datasets like Iris and Titanic survival to recent contributions like that of Air Quality and GPS trajectories. The repository contains more than 350 datasets with labels like domain, purpose of the problem (Classification / Regression). You can use these filters to identify good datasets for your need.
Kaggle Kaggle has come up with a platform, where people can donate datasets and other community members can vote and run Kernel / scripts on them. They have more than 350 datasets in total – with more than 200 as Featured datasets. While some of the initial datasets were usually present at other places, I have seen a few interesting datasets on the platform, not present at other places. Along with new datasets, another benefit of the interface is that you can see scripts and questions from community members on the same interface.
Analytics Vidhya You can participate and download datasets from our practice problems and hackathon problems. The problem datasets are based on real-life industry problems and are relatively smaller as they are meant for 2 – 7 days hackathons. While practice problems are available to people always, the hackathon problems become unavailable after the hackathons. So, you need to participate on the hackathon to get access to the datasets.
Quandl Quandl provides financial, economic and alternative data from various sources through their website / API or direct integration with a few tools. Their datasets are classified as Open or Premium. You can access all the open datasets for Free, but you need to pay for the premium datasets. If you search, you still get good datasets on the platform. Eg. Stock Exchange data from India is available for free.
Past KDD Cups KDD Cup is the annual Data Mining and Knowledge Discovery competition organized by ACM Special Interest Group on Knowledge Discovery and Data Mining. Archives includes datasets and instructions. Winners are available for most years.
Driven Data Driven Data finds real-world challenges where data science can be used to create a positive social impact. They then run online modeling competitions for data scientists to develop the best models to solve them. If you are interested in use of data science for social good – this is the place to be.Image classification datasets
The MNIST Database – The most popular dataset for image recognition using hand-written digits. It includes 60,000 train examples and a test set of 10,000 examples. This serves as typically the first dataset to practice image recognition.
Chars74K – Here is the next level of evolution, if you have passed hand written digits. This dataset includes character recognition in natural images. The dataset contains 74,000 images and hence the name of the dataset.
Frontal Face Images If you have worked on previous 2 projects and are able to identify digits and characters, here is the next level of challenge in Image recognition – Frontal Face images. The images were collected by CMU & MIT and are arranged in four folders.
ImageNet Time to build something generic now. Image database organised according to the WordNet hierarchy (currently only the nouns). Each node of the hierarchy is depicted by hundreds of images. Currently, the collection has an average of over five hundred images per node (and increasing).Text Classification datasets
Twitter Sentiment Analysis The Twitter Sentiment Analysis Dataset contains 1,578,627 classified tweets, each row is marked as 1 for positive sentiment and 0 for negative sentiment. The data is in turn based on a Kaggle competition and analysis by Nick Sanders.Datasets for Recommendation Engine
MovieLens MovieLens is a web site that helps people find movies to watch. It has hundreds of thousands of registered users. They conduct online field experiments in MovieLens in the areas of automated content recommendation, recommendation interfaces, tagging-based recommenders. These datasets are available for download and can be used to create your own recommender systems.
Jester Datasets about online joke recommender systemWebsites which Curate list of datasets from various sources:
KDNuggets – The dataset page on KDNuggets has long been a reference point for people looking for datasets out there. A really comprehensive list, however some of the sources no longer provide the datasets. So, you will need to apply your own prudence on the datasets and the sources.
Awesome Public Datasets A GitHub repository with a comprehensive list of datasets categorized by domain. Datasets are classified neatly in various domains, which is very helpful. However, there is no description about the datasets on the repository itself – which could have made it very useful.
Reddit Datasets Subreddit Since this is a community driven forum, it might come across a bit messy (compared to previous 2 sources). However, you can sort datasets by popularity / votes to see the most popular ones. Also, it has some interesting datasets and discussions.End Notes

Design and Coding for the Complete Package – WMW Conf 7
Roger Sooley from CompStar was up first, his forum name is “rogerd”. He first goes into the question about building the software yourself or using a pre-built software application. The first question you need to ask is “is your business really that different?” When using pre-built software, especially open source, look at proven install counts, look at feedback and requests by the current user base, and most of these have features that you will need down the road – things you did not anticipate. So open source is good for small budgets. But once you have it, you will probably need to make modifications. Software designers rarely design for search engines or what they have done is no longer important (i.e. meta tags). Encouraging signs that new open source applications are SEO compliant.
He then goes on the topic of adding features through outsourcing and goes through some of the points you should look at when selecting a company. Well developed freelance marketplaces, reputation aids, escrow protects buyer and coder, prepare specs carefully, communicate clearly and often, graphics & design can be outsourced too and check that wish list. I personally hate outsourcing any development tasks, I have in the past and it stinks. I only now outsource design projects.
So where do “seems” come from? “Showing off” works against your business. Graphic designers try to show off, or server side spaghetti, client side feature overkill, print mindset, IT folks is writing copy (for auto-responders you see it often). Keep your balance between technology and aesthetics – the whole balance is marketing. He said accidents will happen and showed some funny images of accidents – he also listed some examples of problems that occur.
Then Brett discussed a bit about what he put into WebmasterWorld. His first concern was compatibility with all browsers. He tested every browser, ran every validators and he said it pays off now because it runs on phones now. He said he can run his whole site from his iPaq. In addition, he said he wants to make sure its easy to use. He tries to keep the content way at the top, as high as possible. He said his pages are very simple looking, just like Google. He said he doesn’t really have a logo, he said the most important branding point on the site is the URL (keep the user on the site as long as possible). He said the Google Cache might be the most important thing they did, because it keeps users there. With WMW they have a rule where first time posters, the mods try to welcome and engage them right away. He said he was the first forum to allow for private messaging, so they come back to check their “sticky mail”.
