Linux dependencies 
In order to correctly run Sniffnet on Linux systems, install the libraries and header files for the libpcap library:
sh
sudo apt-get install libpcap-dev
Note that if you are not running as root, you need to set capabilities to inspect a network adapter:
sh
sudo setcap cap_net_raw,cap_net_admin=eip <your/Sniffnet/executable/path>
MacOS dependencies 
MacOS natively has all the dependencies you need to build and run Sniffnet!
Features
- choose a network adapter to inspect
- select filters to apply to the observed traffic
- view real-time charts about traffic intensity (bytes and packets per second, incoming and outgoing)
- view overall statistics about the filtered traffic
- view most relevant connections (most recent, most packets, most bytes)
- save complete textual report with detailed information for each connection:
- source and destination IP addresses
- source and destination ports
- carried protocols
- amount of exchanged packets and bytes
- initial and final timestamp of information exchange

Missing dependencies
Most of the errors that can occur are likely due to your system missing required pcap dependencies,
necessary to correctly analyze a network adapter.
Check the Install and Run section for instructions on how to proceed.
For a Windows reference, you can check issue #1.
Installers incompatibilities
If you have problems after having installed Sniffnet through the provided installers,
it could be due to your OS not being compatible with the pre-built binaries I generated for you.
