Timeout of 0 ms

Question

I don't quite understand the meaning of a 'timeout of 0 ms' which is what the FTPClient defaults to if no timeout is set. Does this mean it will wait indefinitely? If not how can it wait for "zero milliseconds"?

Answer 1

It's a Java default for sockets which means indefinite.

So I don't understand ,why my connection closed after 900 sec ?
If timeout is set to 0?

This is a timeout for socket reads. It is not related to an FTP server timing you out afer 900s of inactivity.

Answer 5

Sure. Do something to let the server know you are alive. Call NoOp() for example.

Answer 6

NoOp()? I'm not seeing NoOp() as a Method for FTPClient in C#. I'm looking for something to keep my connection alive. I'm also looking for a Property to show me whether i am connected or not. For instance, After a FTPClient.Get() I want to say if (!FTPClient.Connected) { reonnect(); } Any suggestions?

Thanks!
