kill TCP connections on a LAN
tcpkill [-i interface] [-1...9] expression
tcpkill kills specified in-progress TCP connections (useful for lib‐ nids-based applications which require a full TCP 3-whs for TCB cre‐ ation).
-i interface Specify the interface to listen on. -1...9 Specify the degree of brute force to use in killing a connec‐ tion. 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.
