Should have done "reply all" on this... ///jon -----Original Message----- From: Jon Maloy Sent: Friday, May 04, 2018 06:11 To: Antony Mayi <[email protected]> Subject: RE: [tipc-discussion] tcpdumping tipc

But intra-node traffic goes directly socket to socket, bypassing even the loopback interface, and cannot be caught.
