One of our programmers is asking me about this and I really don't have an answer. I've checked RFC 793 and haven't spotted the answer yet.
Is there a default time specified in TCP to remain in the SYN SENT state? If a device sends a SYN and doesn't receive a response, is the timeout a built-in TCP parameter or is that a function of the application or operating system? I'm starting to think that this is specific to the operating system, but we have a need to make it specific to a certain connection without affecting all TCP connections. To be specific, they're writing something in Java 1.3.1 (I think) and it doesn't have the capability to tweak TCP parameters. For a particular set of connections they'd like the timeout to be 10 seconds, but it seems to be defaulting to 45. They tell me that if we were using Java 1.4 they'd be able to adjust these parameters, which makes me think this is an application or OS-specific parameter and is only relevant to a particular TCP implementation and could vary from platform to platform. Any thoughts on this?
