2. Packets.
When you opened a captured file in AthTek NetWalk, you will see a new tab named “Packets” created on left. Real-time traffic analysis doesn’t support Packets tab. In Packets tab, network administrators can read all the communication details including requested IP addresses, ports, protocol, etc. If a common packet analyzer enables network administrator to see a naked data, AthTek NetWalk enables users to see a reliable anatomical traffic data through detail and hex view tool.

3. Layered View.
There are 3 layers in Layered View section: Application, Net&Transport and Physical. A significant different is, you can see communication flows in postmortem packet analysis.

4. Events Tab.
In Events tab, network administrator can jump to the communication flow when it is a postmortem packet analysis.

5. Matrix Map.
In Matrix Map, real-time analysis only marks active connections in green, while postmortem analysis marks all successful connections in green.

In short, postmortem analysis enables network administrators to see all communication details happened on the network. All you need to do is to capture packets and open the captured file in AthTek NetWalk.

51% OFF– Buy IP – MAC Scanner Now

Every PC has what is known as a MAC address which is a unique identifier. That is, all PCs that have a network card installed, as it is the network card that carries the unique MAC address. AthTek IP – MAC Scanner can locate the Mac addresses and IP addresses for PCs that are connected to a network. They can also determine the host name, network workgroup and the type of adapter cards of each connected device. There are also remote control functions that can send messages to another PC within the same network, wake the network up or send a shutdown command. Network logs can be emailed out to an admin email address of the users’ choosing.

The best lightweight MAC and IP scanner application for small business should be safe in network scanning. Safe is the most important attribute of a network management system. The MAC scanner or IP scanner itself shouldn’t contain any suspicious program inside, and it must not invisibly upload the result to internet after scanning. If possible, the scanner should be in password protected. Usually, if the MAC or IP scanner can work without internet connections, it was safe for small business, still, you should always get in contact with the salesforce team to make sure you are doing the right thing for your business.

The best lightweight MAC and IP scanner application for small business should be cost-effective. It should be in a cheap price or even free for non-commercial use. Fortunately, there are some free MAC and IP scanners which you can use in a small company. But the features are quite limited comparing with the MAC and IP scanner shareware. For example, if there are more than 200 computers in your company. With a free MAC or IP scanner, you could hardly scan the entire intranet within minutes. Always the free MAC or IP scanner will crash when it reached 50 addresses or so. Actually, there are reliable MAC and IP scanners which cost only $21.

The best lightweight MAC and IP scanner application for small business should be capable but small. It should be able to find more than 100 IP or MAC addresses within 60 seconds, and make all the data backup safely. It should support both ARP and UDP scanning methods and custom scanning range. DHCP clients should be included into the scanning result. It shouldn’t take much space on your computer and the setup file should be in less than 10 MB. With these features, it could be a good lightweight network scanning application.

If you were asked: what is the best lightweight network scanning application for small business, you may have various answers like AthTek IP – MAC Scanner, Angry IP Scanner, Softperfect IP Scanner, Colasoft MAC Scanner or Advanced IP Scanner. Some of them are free. But if you consider all the features of the best lightweight network scanning application I have mentioned, you will find only one could be called “The Best Lightweight Network Scanning Application for Small Business”. AthTek IP – MAC Scanner doesn’t require internet connections to scan the network and backup the scanning results. As a business application, it only cost $21 for lifetime use. It has a small file size but can fast scan the network including DHCP clients. In one word, AthTek IP – MAC Scanner is the best lightweight network scanning application.

Further set your filter with visual logic diagram rather than type complicated codes.

We have discussed the meaning of capturing packets and the significance of setting filters in last my tutorial about filter setting.

Before you starting to capture packets, you need to set your filter to make sure you capture the packets you want. Setting up the filter simply by IP addressed, ports and protocols can meet most of your demands. However, sometimes you are working in a huge Network where there are thousands of computers and you want to analyze some doubtful packets from a certain IP. You may need to set a certain port number or protocol type at the same time. Simple setting is not capable of accomplishing such kind of task.

In this case, the multiple combinations of several kinds of restrictions are needed. If you are using tool like Wireshark, you may need to have well knowledge of Wireshark codes and grammars so that you could set its filter. AthTek NetWalk is an excellent network monitor tool which has aggregated the whole functions of Wireshark for both of new or professional administrators.

When you open the setting window of filter (tools next filter manager) and create a new filter, AthTek NetWalk will show you a visual logic diagram including “And”, “Or” and “Not”.

For example, capturing packets from IP “192.168.1.X” which is sent through protocol IPv4 or IPv6:

• Click the “+” button to create a new filter:
• Organize restrictions in the diagram. Add “And” and “Or” properly:
• 
• Add “And”
• 
• Add “Or”:
• 
• Add more restrictions to set more details including Flow, Pattern, Value, Length and Error.

It is convenient for you to set your filter and show your logic in a simple and clear way which can enhance the accuracy and efficiency meanwhile.

If you would like to use our program in your own language, please contact us and work together with us to translate it to your language. You will receive the lifetime free registration key once you have finished the translation!

Some of users said that the packet sniffing software should be able to minimize to system tray automatically. We have included this function into the new AthTek NetWalk. Now you can choose to minimize to system tray automatically when the program starts, or manually minimize as you wish.

Some of users said that they liked the Matrix Map, and would like to view more info from the communication lines. In AthTek NetWalk v2.1.29, we enhanced the Matrix Map lines to include more communication info into those lines.

There are 120 comments listed on the page, and most of them are far-sighted and meaningful. Thank you so much for the comments and I have to say I had enjoy a wonderful 24 hours with you guys.

The discussion mainly concerns three aspects: former recommendations or certifications of AthTek NetWalk, grammar errors on its site page and the price setting. For the former recommendations or certifications, I’d like to invite you to read these two articles which are from famous software review site:

Software review from addictivetips.com
Software review from navigaweb.net

For the grammar errors, maybe it will take us a long time to locate and correct them all. We would be very appreciate if you can help us the translate all the text on the software pages. Actually I found that there were many features which we haven’t list on out website, but they had been mentioned in your comments, that is really really great! Maybe I can use some of them on our website for thanks to your contribution.

Finally, the price settings. We do have a free personal edition for home users. There are a few limitations but is definitely adequate to your home network monitoring purpose. AthTek NetWalk is more or less overkill for network novice, but can be used just as a network education tool for you to learn stuff of networking. Alternatively, you can free to try another networking tool of us, IP – MAC Scanner. This tool is developed for home user to monitor their small home network, including wireless network with DHCP addresses. It is more easier for use, and you can fast check all the connections to your network.

We have already finished to collect all the suggestions and ideas from GOTD. Some of them will be scheduled in the next version of AthTek NetWalk. I only want to say thanks to all you guys, and we will continuously improve our software and customer servious. If you want to start your business on AthTek NetWalk, we would love to assist you in your market place!
