A question on 4.2 BSD TCP: what is the proper response to a "keep-alive" packet for which the receiving TCP can find no TCB? According to the RFC, the correct response is to generate a segment bearing an RST and formulate the SEG.SEQ and SEG.ACK so as to make them acceptable. My TCP implementation did exactly that. However, the 4.2 TCP on the other end blithely continued to send segments to the non-existent TCB in complete defiance of the RST's. Does anyone know why (more precisely, has anyone seen this type of behavior before)? Dan Reynolds <dan@ngp.utexas.edu> Computation Center The University of Texas at Austin Austin, TX 78712
