Filters configuration

By default all the traffic will be monitored by the application, but you may be interested in setting some constraints to limit the inspection to a particular kind of traffic.
For this reason, you can optionally apply filters on the data analysed and displayed by Sniffnet: this is done in the top right section of the application initial page.

You can selectively configure different types of filter:

• IP version
• Protocol
• Address
• Port

In the following, we'll go through each of them.

IP version

This filter allows users to choose whether to accept or discard traffic based on the carried IP version (IPv4 or IPv6).
To make a change, you just have to press the button relative to the IP version you want to toggle.
By default, both versions are set to be subject of analysis.
Remember that for this filter to be valid at least one of the IP versions must be selected, otherwise you won't be able to start monitoring traffic.

Protocol

This filter allows to accept or discard traffic based on the carried protocol (available options are TCP, UDP and ICMP).
To make a change, you just have to press the button relative to the protocol you want to toggle.
By default, all the three protocols are set to be subject of analysis.

Note

Other existing protocols than TCP, UDP, and ICMP are currently unsupported by Sniffnet and won't be monitored in any case.

Remember that for this filter to be valid at least one of the available protocols must be selected, otherwise you won't be able to start monitoring traffic.
