tcpkill(8)

tcpkill8

Kill tcp connections on a lan

Usage

tcpkill [-i interface] [-1 ... 9] expression

Overview

tcpkill kills specified in-progress TCP connections (useful for libnids-based applications which require a full TCP 3-whs for TCB creation).

Options

-i interface

Specify the interface to listen on.

-1...9

Specify the degree of brute force to use in killing a connection. Fast connections may require a higher number in order to land a RST in the moving receive window. Default is 3.

expression

Specify a tcpdump(8) filter expression to select the connections to kill.
