TCP scanner

TCP scanner is a lightweight and portable piece of software designed to scan a network for a user-defined port. It does not comprise complex options or configuration parameters, so it can be used even by those with little or not experience in networking utilities.

Portability advantages

Since there is no installation involved, you can drop the program files in any part of the hard disk and just click the executable to run.
There is also the possibility to save TCP scanner to a USB flash disk or similar storage unit, in order to run it on any PC with minimum effort and no prior installers.
An important aspect to take into account is that the Windows registry and Start menu do not get updated with new entries, thus no traces are left behind after TCP scanner's removal.

Simple and straightforward interface

The main frame has a plain and simple structure that should be easy to figure out by anyone. All you have to do is specify the LAN class and port number, in order to immediately start scanning.
During this time you can view the status in the bottom part of the window, which shows the currently scanned address and total threads. There are no other notable options provided by this piece of software.

Performance and conclusion

TCP scanner does not put a strain on computer performance, as it runs on low CPU and RAM. However, it may take a pretty long time to complete a scan job. During our evaluation, it stopped right before reaching the end of the LAN class.
To sum it up, users should resort to other similar networking programs for finding out whether ports are open in their network or not.
