The TCP connection establishment protocol is supposed to recover from these 'half-open' connections, but a problem with the 4.2BSD implementation prevented it from working properly. 4.3 has apparently adopted the same fix I proposed, although because of interaction with other BSD TCP bugs I no longer use it in its original form. Presumably, later SUN distributions made a similar fix. -- Brian Thomson, CSRI Univ. of Toronto {linus,ihnp4,uw-beaver,floyd,utzoo}!utcsri!uthub!thomson
