Karen's LAN Monitor

Karen's LAN Monitor is a simple-to-use software application that enables you to study information about your network adapters and check out all connections established by remote computers via LAN.
It doesn't include complicated options or configuration parameters, making it accessible to all types of users.

Simple setup and UI

After a quick and uneventful setup procedure, you are greeted by a classical window with a seemingly outdated look, split into different panes dedicated to each major component.
You can select a network adapter to find out its properties, such as name, description, speed, maximum transfer unit, index, physical MAC address, operational and administrative status, along with associated IP addresses and DNS servers.

Inspect and export network information

Furthermore, you can examine all phone book entries found in any dialup device, as well as view remote connections when it comes to the remote and local IP address and port, show UDP listeners and loopback connections, or display remote PC names.
It's also possible to monitor network traffic for any adapter or to inspect statistics for the IP (e.g. received datagrams, header errors and routing discards), TCP (e.g. failed attempts, sent and received segments), UDP, and ICMP. Information for any of these panes can be copied to the Clipboard or directly saved to text documents for closer investigation.

Evaluation and conclusion

As expected, Karen's LAN Monitor had minimal impact on the overall performance of the computer in our tests, using low CPU and RAM. It didn't hang, crash or prompt error dialogs. Thanks to its simple interface and straightforward options, this app can be handled by anyone who wants to examine network traffic.
