I've been testing out a scenario on windows and linux and I have a question= for what FreeBSD does or rfc1122 says: (The code is in java using java.ni= o) An application (host) has established a remote connection to another machin= e. The OS on the host receives the following packets in order for that so= cket: Data packet (6 bytes) FIN packet RST packet At this point the application (host) tries to read from the socket. On w= indows, this causes a "the os has closed the connection" exception and doe= sn't let you read those 6 bytes. On Linux, those 6 bytes can be read. I've looked over the TCP rfc: http://www.rfc-editor.org/rfc/rfc1122.txt = . But it's not clear what should happen to 6 bytes once a RST packet arri= ves. Does anyone know what the correct behaviour is? Or point me to freebsd's t= cp stack code? Thanks,
