This is probably a rediscovery of an old mistake, but in RFC-793 (TCP Protocol Specification) in the TCP Connection State Diagram on page 23, the transition from the SYN-SENT state to the SYN-RECEIVED state by the reception of a bare SYN, indicates that this should case a bare ACK to be sent. However, on page 32 (Simultaneous Connection Synchronizaton) and text on page 68, it would appear that the correct thing to do is to send a SYN,ACK. If this is a known problem, is there an RFC or other location where known problems are kept? Bruce

Bruce, There is actually a move afoot to write a Host specification document ala RFC 1009 (the Gateway specification). One of the sections in this document will be devoted to TCP. I'm responsible for writing the first draft of that section, and I plan to incorporate a list of known problems in the TCP RFC. Anyone who has a list of errors they've found in the TCP specification is encouraged to send those errors to me so they can be noted in the RFC. Craig PS: Bob Braden is editor-in-chief of this effort.
