Capsa network analyzer review from wireshark.com.

Capsa is a powerful network analyzer for Ethernet analysis, troubleshooting and monitoring. Not only does it provide users with a series of powerful features that help them learn more about improving network security, pinpoint network issues and monitor network activities, but it also features a user-friendly interface that makes using it a breeze. The software is generally targeted at computer professionals and/or teachers who want to learn more about networking technology, protocols, monitoring and security.

Real time monitoring

As a packet sniffer, Capsa is capable of real time packets monitoring and can also presents the data visually by using logs and a GUI for future reference. Given the fact the software is capable if easily analyzing and diagnosing problems on a network, it can tell the user in minutes what is causing it to be slow or if there is an attack that may be the culprit for its poor performance.

In identifying network issues, Capsa can find the top ten local hosts that slow down the network and can also detect whether someone is using a Bit torrent client to download files off the web which is obviously a prime cause of slow network performance.

Safety and security

Should an attack be responsible for the network’s poor performance, the software will immediately locate the packet info and source codes from the host so that the admin can promptly begin investigating the issue. There are 2 types of worms the software can locate, including operating system works and E-mail worms. This functionality is paramount in identifying the infected computers which eventually allows the admin to fix these issues.

Available filters

In order to be able to focus on specific packets, administrators can use a wide range of filters right from Capsa’s dashboard. For instance, admins can monitor real time messages, http requests, E-mail messages and more of the 4 most popular IM apps including YM, ICQ, AIM and MSN.

Other features

There are of course many other features that Capsa incorporates, such as the ability to generate reports of a certain group or global networks automatically, but also customize the data on different charts. As a network administrator, you can also use the software to remotely monitor traffic by installing the application on the business network (on a workstation of course) and using the Remote Desktop Access function.

Conclusion

All in all, Capsa is by far one of the most reliable and simply the best network analyzers out there. Not only does it offer a wide range of improvements that make using it a breeze, but it makes it very easy for anyone who uses it to find the info they need. On top of that, thanks to functions such as reports, Matrix and Diagnosis, it definitely stands out from the large crowd of similar programs available today.

If you’re a network administrator, you already know how critical it is to have tools at your disposal to keep you apprised of the status of your network and its connected systems. Among the gazillion different apps for Windows, there are numerous different tools and utilities that can aid in network administration. Colasoft’s Capsa desktop application for Windows is one such highly feature-laden, comprehensive network analyzer that can help you in analyzing both your LAN and WLAN in real-time. The application carries a wide array of features including 24 hour network monitoring, advanced protocol analyses, in-depth packet decoding and capturing, and automatic diagnosis.

The software can be deployed in a number of scenarios and usage needs, for instance, troubleshooting various network related issues, analyzing your networks performance and pinpointing any bottlenecks, detecting malicious activities in the network, for example, presence of virus or worm, as well as debugging other similar problems.

Capsa is a freeware program but you need a free license key in order to activate it. To get your license, simply fill in the sign up form at Capsa’s website  and the developer will email the key to you.

Once you have received the key, enter it in the ‘Serial Number’ field during the setup wizard, enable ‘Activate Online’ and click Next.

Capsa basically comprises of two different windows. The one that pops up upon launch, looks fairly understandable. It carries two tabs at the top labeled Capture and Replay. Under Capture, you can select the network interface you require to monitor or analyze. As stated earlier, Capsa works well with all wired and wireless interfaces, including Bluetooth, Wi-Fi and Ethernet. And toggling an interface displays its bandwidth stats in real time.

Capsa houses a number analyses profiles, and it’s up to the users which profile they want to deploy. For an in-depth analyses, you can choose Full Analyses, but if you need to analyze different network modules separately you can do that too by choosing the appropriate profile name. These analyses types include Traffic, HTTP, Email, DNS, FTP and IM. After selecting the analyses type, you can click ‘Start’ to initiate the capture process.

The main window of Capsa then shows up, providing a wide range of statistics and analysis results. The Ribbon-like UI of Capsa carries a menu bar at top, the main Ribbon, a node explorer to the left, status bar, and the main view at center. You can also stop and resume the capture process anytime. The application displays various different kinds of information and its up to the users how they approach with the analyses of the network.

The sub-tabs within the main view section of Capsa allow you to navigate between various sub sections, fourteen in total, such as statistics, logs, reports, graphs, data packets, diagnosis results and so on. There’s also a Node Explorer to the left which gives an overview of physical and IP addresses of the network, giving you a general understanding of your network.

Capsa also lets you save captured packets by exporting the results as a Capsa-compatible file and save it to your hard disk. You can then replay the same file later from the ‘Replay’ tab that I mentioned earlier. To do that, click Replay button when Capsa is relaunched, under Replay tab, click Add, select the packet file you saved and click Start to initiate replay.

Overall, Capsa is an extremely useful and feature-rich program if you need to monitor and analyze various aspects of the network. Besides its Free version that we reviewed, it also comes in Enterprise and Professional editions both of which offer additional features. It works on all versions of Windows.

Colasoft Capsa Packet Analyzeris a free network analyzer software which can be used toanalyze and monitor WLAN andLAN networks. What it actually provides is network monitoring,in depth packet decoding, andadvanced protocol analysis of the network you are connected to. The best part is you do not have to install this software on a server to view the details; installing in any client machine of the network will provide you with all the necessary details.

Well the software has a number of functionalities, like:

• Troubleshooting Network Problems.
• Know about the performance of the network thus finding any bottlenecks.
• Can be used to detect virus,worms, or network attacks.
• It can also be used to teach and learn various things about network.

Here we will talk about the free version of Colasoft Capsa which has limited capabilities, like you can monitor the network continuously for 4 hours only using a profile and you can use only 1 analysis at a time.

How to use Colasoft Capsa Free Network Analyzer:

When you are downloading Colasoft Capsa, you will be asked to register with your email address. On this email address, you will be sent activation key, which will be valid for 4 months, after which you have to renew. The installation process will take a minute or two. After the installation is over you will get the home screen which looks like the first screenshot of this review.

At first, you have to select the connection from the adapter which you would like to monitor. When selected, it immediately shows a graph for the speed of the network.

The profile section allows you to select what type of analysis you would like to do. The software offers:

• Full Analysis
• HTTP Analysis
• Email Analysis
• DNS Analysis
• FTP Analysis
• IM Analysis
• Traffic Monitor

Full Analysis

Clicking on Full Analysis gives you various information regarding broadcast addresses, multicast addresses, local subnet, the IP addresses of the computer connected, etc. The center screen has various tabs like Protocol- tells about different protocols like IP, ARP, IPv6 and the amount of data and packets being transferred.

Physical Endpoint, IP Endpoint which tells about the MAC address and the IP address of the connected systems. Other tabs include TCP, IP, and UDP conversations. Somefunctionalities may not work in the free version.

HTTP Analysis

The HTTP analysis gives you the various results regarding HTTP protocol. At any normal instance it will give the IP address of the computers with which your computer has a HTP connection. Through the IP, TCP, and UDP conversation you can know the amount of data and packets being shared among the computers.

The other analysis gives out more information regarding data and packet movements in the network you are connected to.

Talking to one of my friends who is a ethical hacker and wants to remain anonymous, said that the software is great. According to him:

• This is really a great software and very powerful.
• It helps the network administrator to get various details about the network in real time.
• It can be used for educational purposes as the software tells how packet movement works actually in the network.

Downsides of the software

In the free version, the user cannot use more than one analysis simultaneously. If he wants to have a different analysis he must close the ongoing analysis. The free version has most of the good features restricted not allowing users to know the software’s working properly.

Also check out other network packet sniffer software.

Conclusion

It is a cool software to monitor the data traffic of your network. If you setup a private network you can watch out for any wrongdoings that might happen be happening in the network. It is very much useful for those who want to know more about computer networking.

Gizmo’s Freeware , a non-commercial community website staffed entirely by volunteers, published an article about Colasoft Capsa on Mar.6 2014 which reviewed Colaosft Capsa as the friendliest network traffic monitor ever.

Here’s the review written by Rob.Schifreen.

If you’ve ever wanted to be able to view a log of all the data that passes through your PC’s network connection (either wired or wifi), you may know that this is possible with a network protocol analyzer utility.  Such programs let you find out who your PC’s been talking to, and what was said.  You can view the content of every packet of data that travels to/from your PC and all of the remote computers and websites that you connect to.

By far the best-known of the network protocol analyzer software products is Wireshark.  It’s powerful, free, and does the job.  However, it also has a very steep learning curve and is far from intuitive to use.

Which is why I was so impressed to learn about a product recently called Capsa, which does a similar job but is way more friendly and much easier to understand.Capsa is from Colasoft, and you’ll find it at http://www.colasoft.com/capsa-free/.  Considering the full Enterprise version costs around $1000, the free no-commercial-use version, which offers pretty much all the features you’ll need, is a bargain.

It’s a 20 MB download, malware-free according to VirusTotal, and should work on all recent versions of Windows. So next time you need to know what’s eating up all the network bandwidth on a computer, or precisely what information a certain application is sending out about your PC, you can track it down with Capsa.

Overview

Anyone working in the IT Industry could benefit from using Capsa Professional, this software is capable of tracking network activity to a very extensive degree. The list of available features goes on and on, with the main feature being detailed packet monitoring, and a tremendous amount of information regarding traffic on your network. Capsa also offers some really helpful guides for new users who aren’t familiar with this type of interface. Using this software can help you track down the root cause of a slow or unstable network, and also assist in fixing the problem.

Installation

You can download and install the 15 day trial of Capsa Professional for free, and it is only compatible with Windows. The trial is also limited in features, but you’ll still get the look and feel of the full program. No bundled software included, just a regular installation and you’re on your way.

Interface

Capsa Professional offers a large, scale-able interface, and is all around pretty easy to navigate once you become acquainted with the software. Most of the tools will open up in a new window, which ensures that your main screen never gets cluttered with different tabs. However, with this much information, it’s pretty much guaranteed to be overwhelming at first — unless you’re a seasoned network professional. In general, Colasoft did a great job organizing the extensive list of features, which is not an easy task.

Interface is a major issue with most suite-style network monitoring software, and it’s very refreshing to see something as well put together as Capsa.

Pros

Along with the aforementioned packet monitoring capabilities, intelligently organized UI, and the fact that it can narrow down network issues to help find the root cause of a problem, there’s plenty more. Capsa Professional can be used to scan all MAC addresses on your network, as well as grab their IPs, names, and information about the manufacturer. You can also monitor a specific network adapter, or multiple, such as your ethernet port, wfii adapter, or both.

The tutorials are fantastic as well, as mentioned above, and there are even specific guides such as “How to monitor Employee Website Visits”.

Cons

The program is stable, offers everything you’ll need in network monitoring, and there’s really nothing I can say that needs work at this point. Obviously the heavy price tag is a bit daunting, but considering this software is really only necessary in a large work environment, it’s nothing to complain about.

Alternatives

Also, Capsa even offers a free version, much more suited towards troubleshooting home network issues.

Conclusion

Troubleshooting network issues can be a major pain for any IT Technician, and I’ve personally been in that situation numerous times. Using Colasoft Capsa Professional will greatly reduce the time you spend trying to find the cause of these problems, and will help you get the issues resolved much quicker.

If you run any type of network infrastructure there will come a time you need a low-level packet sniffer to work out just what is going on. Colasoft’s Capsa product challenges the myth these tools must be hard to use.

Have you ever had users ask why is the network so slow? Chances are high any IT professional will have looked into network related faults but found it difficult to get a handle on just what is going on because Ethernet is so, well, ethereal.

Here is where a network analyzer comes in handy. It will sniff the raw packets of data flying about as they happen and give you meaningful information to make intelligent determinations.

Previously I have talked about the tremendous open source product WireShark but WireShark isn’t for everyone. For one, the Windows port requires GTK+ and Glib to be installed which some Windows administrators aren’t keen to do. For another, although it is less arcane and cryptic than a command-line tool like tcpdump it’s still not user-friendly enough for many.

Here is where Colasoft’s Capsa product comes in. As you might guess, it is a deep low-level network protocol analyzer and its purpose is to give you the low-down on just what is happening on your network.

Where it stands out from the competition is its brilliant ease of use. Capsa adopts the same ribbon style interface as seen in Microsoft Office 2007 and it is a snap to navigate between tabs and check out the options and power available.

When it comes to network analysis so much is going on that it’s a must to separate out the chatter from the data that matters. Capsa makes it a cinch to hone in on what you want with easy to use filters and rules.

Capsa also has a concept of projects, meaning you can set global filters and rules to always apply but also make specific filters and rules for individual projects, letting you switch between these as needed.

Capsa displays intuitive options and is a genuine pleasure to use. I do not believe I’ve seen a more straightforward or elegant network analysis tool with the majority requiring expert knowledge to get any meaningful results.

Capsa is a commercial product so it does carry a price tag beginning at $US 549 for one license without maintenance but if your job requires you to troubleshoot network faults then the software will pay for itself.
As well as the commercial support Colasoft provide an extensive and helpful FAQ. A free trail of Capsa is avaliable here.

Introduction

A Network Analyser is without doubt an Engineer’s best friend.
Using network analysing software, we are able to monitor our network and dig into the various protocols to see what’s happening in real time. This can help us understand much better the theoretical knowledge we’ve obtained throughout the years but, most importantly, help us identify, troubleshoot and fix network issues that we wouldn’t be able to do otherwise.
A quick search on the Internet will surely reveal many network analysers available making it very confusing to select one. Some network analysers provide basic functions, such as packet sniffing, making them ideal for simple tasks while others give you all the necessary tools and functions to ensure your job is done the best possible way.
Colasoft’s network analyser is a product that falls in the second category. We had the chance to test drive the Colasoft Network Analyser v7.2.1 which is the latest available version at the time of writing.
Having used previous versions of Colasoft’s network analyser, this latest version we tested left us impressed and does, in fact, promise a lot no matter what the environment demands.

Colasoft’s Capsa network analyser is available as a demo version directly from their website www.colasoft.com. We quickly downloaded the 21.8mb file and began the installation which was a breeze. Being small and compact meant the whole process didn’t take more than 30-40 seconds.
We fired up the software, entered our registration details, activated our software and up came the first screen which shows a completely different philosophy to what we have been used to:

The Software
Before you even start capturing packets and analysing your network, you’re greeted with a first screen that allows you to select the network adaptor to be used for the session, while allowing you to choose from a number of preset profiles regarding your network bandwidth (1000, 100, 10 or 2 Mbps).
Next, you can select the type of analysis you need to run for this session ranging from Full analysis, Traffic Monitoring, Security analysis to HTTP, Email, DNS and FTP analysis. The concept of pre-configuring your packet capturing session is revolutionary and very impressive. Once the analysis profile is selected, the appropriate plug-in modules are automatically loaded to provide all necessary information.
For our review, we selected the ‘100Mb Network’ profile and ‘Full Analysis’ profile, providing access to all plug-in modules, which include ARP/RARP, DNS, Email, FTP, HTTP and ICMPv4 – more than enough to get any job done!
Optionally, you can use the ‘Packet Filter Settings’ section to apply filters to the packets that will be captured:

by Michael Dragone at June 1, 2010.

At some point in the career of almost any IT professional, there comes a time when a detailed examination of network traffic at the packet level is required to troubleshoot a problem. These problems often occur at the worst time, and having the ability to quickly perform a detailed traffic analysis is critical to resolving the problem swiftly and efficiently.

In the field of network analyzers, there’s a range of choices. On the one end, you can obtain free tools that support basic capture tasks but require you to perform much of the analysis. On the other end, you can purchase multifunctional tools that perform the analysis for you.

I took at look at the recently released Capsa 7.1 from Colasoft to see how it performed. I was especially interested to see how it fared against free tools such as Microsoft’s Network Monitor and Wireshark (formerly Ethereal). I ran the software on a Windows XP Professional SP3 computer.

Capsa downloaded quickly, and the installation process was brief. During installation, I was given the opportunity to install additional Colasoft tools such as a packet generator. I declined because I was focusing on the network analyzer, but it was nice to see those tools included as an installation option and not as an additional download. I was also happy that the installation process gave me full control over the creation of the desktop and Quick Launch icons instead of littering my test computer with icons everywhere. Finally, I was expecting to have to reboot my computer after the installation, as I assumed that the installation routine would make changes to the network stack. I was happy to see that this wasn’t the case and no reboot was required.

When you start Capsa, an interface presents you with intuitive options that let you select the network you want to analyze and the type of analysis you want to perform, such as Full Analysis, Traffic Monitor, Security Analysis, and Email Analysis. I wanted to analyze traffic, so I selected Traffic Monitor and clicked the large play button. The analysis began immediately.

As Figure 1 shows, Capsa uses the Fluent interface introduced in Microsoft Office 2007. As such, it’s extremely easy to navigate and almost, dare I say, fun to poke around the various tabs as the product captures network traffic.

The information that the product can capture can be daunting, but it was easy to filter the capture to look for only HTTP traffic. The filter interface provides an excellent graphical representation of what your newly created filter will do.

I was able to drill-down into my newly captured HTTP traffic to the packet level and examine all the details. Because it was encrypted HTTP Secure (HTTPS) traffic, I couldn’t look into the data payload, but all the header details were available. I was also able to examine entire TCP conversations, from the initial handshake all the way down to the FIN flag. The graphical representations that this product can produce are simply wonderful.

Overall, Capsa is a joy to use. My only complaint is the high price tag, which might make it difficult to obtain if you don’t spend a majority of your time examining network traffic, as free (and excellent) alternatives exist. Despite this, I highly recommend this product and would be glad to add it to my toolbox.
