FTP Upload Issue

#1 Post by dnavarrojr » 2008-09-15 22:10

I upload images and footage to several agencies using FileZilla.

The servers for each of them run bots that move files as soon as they are finished being uploaded. Typically, this means that FZ thinks there is a problem with the uploaded file and re-uploads it.

There have been a few times I forgot about my uploading session and this "round-robin" has gone on for hours.

I can't find any setting which tells FZ not to check if the file exists after uploading.

Look into the message log, there have been transfer errors.

Okay, what happens is this...

If the transfer takes more than 10 minutes (which is the case 90% of the time), the primary connection is closed by the server. When that happens FZ re-uploads the file over and over and over again.

If the transfer takes less than 10 minutes (or the connection is not closed) then it recognizes the file transfer is successful.

I tried enabling keep-alives, but that didn't keep the primary connection open.

It doesn't get closed by the server. It gets closed by a horribly broken firewall or router.

See http://tools.ietf.org/html/draft-ietf-behave-tcp-08 for details. No router or firewall should ever drop an idle connection unless no packet has been sent in more than 2 hours 4 minutes.

Um... Okay, so I'll look at my router settings.

Other than that, I'm SOL, I take it...?
