I added this to the test code but it failed as: Server: Created. Server: Binded. Server: Listened. Client: Created. Client: Connected. Client: Written. accept: Software caused connection abort Of course, setsockopt() was added also before connect(). So, I moved the setsockopt() from just before accept() to just before listen(), then it succeeded. Server: Created. Server: Binded. Server: Listened. Client: Created. Client: Connected. Client: Written. Server: Accepted. 10: 1234567890 Server: Read. Does this affect to listen() as well? -- Takashi Yano <takashi DOT yano AT nifty DOT ne DOT jp> -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
