Packetz::Capture

Inherits Reference / Object

The Capture class is responsible for all of the supported capturing operations provided by LibPcap in a clean, friendly API.

Simply start a new capture object called cap, with all the defaults:

cap = Packetz::Capture.new

If you want to start customizing the capture object during initialization, you have a few ways to do that to change the interface, snapshot_length, promiscuous_mode and timeout_ms values of a capture.

Listen specifically on the en0 network interface:

cap = Packetz::Capture.new("en0")

Listen with alll the default options, but in promiscuous mode:

cap = Packetz::Capture.new(promiscuous_mode = true)

Change the default snapshot length from 65535 to half that size.

cap = Packetz::Capture.new(snapshot_length: 65535/2)

Constructors

new(interface : String = Packetz.interfaces.default, snapshot_length : Int32 = 65535, promiscuous_mode : Bool | Int32 = 0, timeout_ms : Int32 = 1, monitor_mode : Bool = false)

The #initialize method takes care of setting up a new Capture object.
