v4.1.7 FTP Problem - Uploading large files

2008-10-24 14:41

Hi,

I'm using WinSCP Version 4.1.7 and I have a problem with the FTP-Protocol.
I think I have narrowed the problem down, it should be a bug (sorry if it's not).

When I am transferring rather large files via FTP and the session disconnects / you receive a session timeout, but the session still finishes uploading, then WinSCP tells me it needs to reconnect, does so automatically but does not see that the file is already uploaded. This way, if there are big files that provoke a session timeout when uploading, it re-uploads (or tries to do so) over and over again or just receives an error (cancelling the upload) if the file permissions are not set on overwrite/delete.

It seems the program does not check if the file is already downloaded. This happened to me on different servers I wanted to upload to and does not happen if the Session Timeout is set rather high or turned off.

cheers,

I am getting exactly the same behaviour since upgrading.

I am not able to download large files to either of my servers with WinSCP since upgrading to 4.1.7.

I am getting a "Confirm" window with the text
"Host has not answered for more 15 seconds. Still waiting

Warning: Aborting this operation will close connection."

and an abort button. I am including a log below

Thanks. Can you post a log file?

Hi again.

I fetched a log file. I stripped it from some personal information. As far as I can see, the information necessary should be in there. If it's not enough, tell me again :-)

cheers,

May I have a test account on your server?

Sorry, but that's not possible (technically).

The FTP-Server I have tried it on runs the GeneFTP 6 Software, maybe there is an open server somewhere that uses it, but it might be possible to get the same problem on any server software if the timeout is very small.

OK. Would setting longer timeout resolve the issue?

I didn't think of that. I don't have time right now to test it, but I'll test it as soon as possible and come back here with the result.

Sorry in Advance, I thought I had answered to this post already.

I tried to play with the timeout settings, but alas it did not work. However, I found a workaround (although I don't like it very much). I installed FileZilla because I had to upload a lot of large files. The initial start of the program told me that FileZilla, in combination with the started service "Application Layer Gateway" (alg.exe), leads to problems with large files. I deactivated the service and tried to upload the large files with WinSCP again. Now, the upload seems to work perfectly.
It seems the problem lies with the Application Layer Gateway itself. I don't want to keep it deactivated forever, but it is a small workaround and maybe you can do something with that information.

Cheers,
