false report in download file successfully and auto reconnection is not work

[rio]

I found that when I download some hugh files from a ftp site, the windows status reports that "Transfer queue completed" and disconnected at once without reconnection. The On Transfer Complete is Idle, and the file is actually not completely downloaded. But why the queue is cleared for this file? My question is:

1, Will Flashfxp compare if the downloaded file size is the same as its total sized from the queue? If yes, then reconnection should occur.

2, Is there anything specially happened to this ftp server which have done something to disconnect people suddenly or after certain amont of time on connection, but the disconnection status won't report timeout wordings, so as not to allow ftp client to reconnect automatically?

Some ftp connection status are shown for ref as follows:


220 Serv-U FTP Server v3.0 for WinSock ready...
USER ccnuftp
331 User name okay, need password.
PASS (hidden)
230 User logged in, proceed.
SYST
215 UNIX Type: L8


Thanks for any advice.

Could you please show the ftp status where it shows the file download and then it being reported as completed. That would be most helpful

Ah I see you're using "send Noops during transfer" This option is very problematic and often leads to more problems than it solves, it may be the cause of this failure. I would recommend you disable the option and see if it resolves the problem.

Ok, I'm trying now to uncheck "send keep alive.." and "stop sending keep alive..", and see if it works. Thanks.

Hi bigstar, I've unchecked both Anti idle keep alive options, but I don't see why the repeated "200 Command okay" messages keep displayed, and all the negative symptoms still exists without improvement.

Is there any more things do I need to do?

[Linkster]

no, wrong setting....its a setting under Options/Preferences/Proxy.firewall.ident....called "Send noops during transfer". Uncheck that.

[rio]

Ok, thanks Linkster.

It's seems working fine now. Thanks!!
