Network Troubleshooting Made Easy, A Colasoft Software Solution

The Challenge
As the business is becoming more and more networked, it’s always necessary for network administrators to troubleshoot network issues in shortest time possible if the network is not functioning properly. Network downtime or network malfunction may cause headaching inconvenience or even millions of business losses if not settled up in time. Without a handy tool, network troubleshooting can be time-consuming and frustrating.

Old Ways – Time-consuming and Frustrating
There are a lot of articles providing guidance on how to troubleshoot network issues in general ways. For simple networking issues, these tutorials work fine. However, for a company-level network, issues are often complicated and mixed, and these issues require deeper analysis and stronger diagnosis abilities. Obviously, old ways are no longer suitable for today’s in-time network troubleshooting demands.

Troubleshooting Network Issues in Seconds
To troubleshoot your network in time, even in seconds is now possible with Capsa’s diagnosis feature. Network issues are automatically detected and clearly identified, with possible causes and solutions provided.

Automatic Diagnosis
Based on Colasoft’s packet analysis engine, Capsa is able to automatically detect network issues in different OSI layers, such as application layer, transport layer, and network layer. All these issues are marked with different severity levels, indicating which are critical issues that need to be addressed immediately, which are just informative messages.

Quick Locate Suspicious Host
Once a critical network issue is detected and requires immediate handling, we can select the item from the list, then detailed information will be provided under, including source, destination, port and so on. We can easily locate the suspicious host in this field, for example, the attacking host or the host which is spamming our network. Moreover, after locating the suspicious host, we can conduct deeper analysis, such as protocol analyzing or packet decoding.

Possible Causes & Solutions
When selecting a network issue from the list, possible causes and solutions are also provided for users to understand the issue and solve it as soon as possible.

Customizable
Depending on network sizes and network’s characteristics, we can customize the threshold that triggers one diagnosis event and the severity of the network issue.

Conclusion

It is always good to maintain the network running smoothly and properly without any problems. However, if a network issue arises, we must make sure it is quickly detected and solved before it affects the entire infrastructure and brings loss to our business. For the complexity of the network and variety of network applications, network troubleshooting is becoming more challenging and demanding. To have a powerful tool like Capsa in hand is must in everyday’s network management.

Top 10 Uses of Packet Sniffer Software

Packet Sniffer software is a network monitoring tool that helps us to be in control of our network 24/7. All computer networks that are connected to the internet are highly vulnerable to security risks. If our networks are not constantly monitored, we can easily become a prey for the hackers. Packet sniffer software logs all traffic and all data that is sent in and out of the network that matches the specific packet criteria set by the network administrator.

Packet sniffer software has a number of uses and all of them are of critical nature.

  1. Whenever there is a network related problem, we need some basic clues so that we can start addressing the problems. We will be able to get these clues from the packet sniffer software that is installed in the network. Therefore, packet sniffer software will not only help us monitor the network, but it will also help us analyze the network traffic so that we can identify any problem that crops up in the shortest time possible.
  2. If there are any unauthorized intrusions, we will be able to detect the intrusions in good time. This will help us protect our network from the hackers.
  3. We will be able to monitor the usage levels of the network at any given time. This will help us optimize the usage if we need to.
  4. Using packet sniffer software we can keep a tab on each user in the network and gather sensitive information including passwords.
  5. Packet sniffers will also be useful to monitor ‘on the fly’ network traffic to determine what is going on in the network at any given time.
  6. Packet sniffers are not only useful for network administrators, it is also useful for programmers and security professionals to study the network traffic and possible loopholes so that they can be sealed.
  7. Parents can keep a tab on their children’s online PC usage.
  8. For those who are in learning stages packet sniffer will help them understand various protocols of the network such as HTTP, POP3, STMP, etc.
  9. The reports generated can be used to build reliable statistics about the network use.
  10. You will be able to find reasons for system slowdown. Using the packet sniffer software you will be able to troubleshoot the problem in the shortest time possible.

There many other uses besides the ones mentioned above. In addition, there are many packet sniffer software products available in the market.
