Little Snitch 6 Help

Connection list

Overview

Connection List

Little Snitch records all network connections established by processes on your computer, and shows them in the connection list of Network Monitor. Connection data is collected for up to one year, limited to 50,000 distinct connections by default. This limit can be increased to up to 200,000 in Settings.

In order to work with such a large list of connections, Network Monitor can filter the list by various criteria.

Hierarchy of grouping

By default, Network Monitor groups connections into the following hierarchy:

Click the disclosure triangle to expand the details of a line. When you hold down the option key while clicking, details are expanded recusively. When you hold down the command key, more items lines are also expanded. And if you hold down both modifiers, details and their more items lines are all expanded recusively.

Alternative grouping hierarchies are available and can be chosen in the view options. There are options which reverse the hierarchy (domains first, then apps) and options which include grouping by country.

Sort order

The sort order of connections can be changed in the view options:

When sorting by traffic amounts, the amount based traffic meters are used. For all other sort orders the meters configured in Settings are used.

Traffic meters

STYLE DESCRIPTION
Current Rate Meter Indicates the current data rate.
Rate History Meter Indicates the amount of data transferred within the last five minutes, each bar representing approx. 40 seconds.
Total Amount Meter Indicates the amount of data sent (pink on the left) and received (blue on the right).
Sent Amount Meter Indicates the amount of data sent.
Received Amount Meter Indicates the amount of data received.

Context menu

Each row in the connection list has a context menu which can be accessed via right-click. Options related to rule management are discussed in a separate section.

Hidden connections

Network Monitor collects a plethora of information about all the Internet connections of the programs you use. Although this information is protected from access by others (using encryption), you may prefer if particular data is not collected or stored to begin with. For instance, you may live in a country where visiting certain websites can get you into trouble and you don’t want any traces to be stored on your computer.

Little Snitch offers a mechanism that deals with this: Rules to Hide Connections. If such a rule matches a connection, Network Monitor summarizes traffic statistics in a single Hidden Connections row. These rules can be created in Little Snitch Configuration or in the context menu when you right-click on a process in the connection list.
