class Packetz::Capture
- Packetz::Capture
- Reference
- Object
Overview
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.newIf 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)Defined in:

.new(interface : String = Packetz.interfaces.default, snapshot_length : Int32 = 65535, promiscuous_mode : Bool | Int32 = 0, timeout_ms : Int32 = 1, monitor_mode : Bool = false)
The
#initializemethod takes care of setting up a newCaptureobject.
