Problem uploading large files

[paul-dancey]

FlashFXP v3.6.0, build 1240, registered, OS WinXP, Running behind hardware router/firewall Model Speedtouch 585, Running software firewall and Antivirus Zone Alarm, Network DSL.


I seem to be having problems uploading pdf files over 2 meg via ftp, when it reaches around 2 megs it simply disconnects and starts again. But if I use the file manager in cPanel on the same connection, server and file this works fine. I've checked with other server users and no one else seems to have the same problem, so I'm assuming this isn't a server issue.

I'm Uploading using FlashFXP using passive mode and compression. Any thoughts or suggestions as to what the problem might be.

Many thanks
Paul

Hello,

Using the file manager in cPanel isn't the same as using a regular ftp client, so we can't rule out a server issue. The only way to know for sure would be to test using another windows ftp client. Make sure Zone Alarm is correctly configured to allow FlashFXP access to the internet, sometimes these types errors can be related to an incorrectly configured firewall. Sometimes the easiest way to determine the problem is based on the ftp sever session log, if you can copy and paste this from FlashFXP, it will be critical factor when determine these types of issues, enabling time stamping will help too. You can do this by right clicking on the ftp session log window.

Thanks for the reply. Fair point.

I've now downloaded filezilla and tried with that and successfully uploaded a 4.6mb file.

I then tried uploading the same file with Flashxp and when it reached around 2meg I got transfer failed followed by disconnected. I've pasted the full log below with the sensitive bits removed:

Now the curious thing is that I then thought I'd try with the TLS option selected. I still received the Transfer failed message and disconnected when it was showing a bit over 2meg, but this time I had an additional error message:

[R] STOR xxxx.pdf
[R] 150 Accepted data connection
[R] 421 Timeout (no new data for 900 seconds)
[R] Transfer Failed!
[R] Connection lost: xxxxx
[R] Attempting to Reconnect.

Which seems odd as the % upload bar never really seems to stall.

I finally tried lowering the send buffer to 64k (it was 256k), but that had no effect.

The part file that shows as having been uploaded always seems to be 1.98meg.

It has to be something simple. But I blowed if I can spot it at the moment.
