FTP server problems

rthomas · 3 Dec 2009, 05:27 PM

Hi,

For several days problems with the FTP server.
First, the server is slower than usually, max 100 Kb/s (I used to have 250 Kb/s)
Second, the most important, I get timeout when upload is finished. I tried with different FTP clients.

FileZilla log:
Command: LIST
Response: 150 Opening data connection for file listing.
Response: 226 Listing complete. Data connection has been closed.
Status: Directory listing successful
Status: Starting upload of Z:\dev\clients\Masterprint4\geideon.zip
Command: TYPE I
Response: 200 TYPE changed to I.
Command: PASV
Response: 227 Entering Passive Mode (66,111,4,57,219,208)
Command: STOR geideon.zip
Response: 150 Opening BINARY mode data connection for file geideon.zip.
Error: Timeout detected!
Error: Upload failed

Trace complete.

Also have slow upload from Web file manager.
Can we get normal speed back?

Why do you say 'upload is finished'? If the upload is completed, the file should appear on the server. Do you see that? I suspect the file is not getting uploaded at all.

From getting the "150 Opening BINARY mode", how long do you have to wait before the timeout?

What about sending big email attachments(say above 1MB) from the web interface. Does that work? If you haven't tried yet, please try and report the results.

And what Windows version are you running? XP or vista or something else?

rthomas · 3 Dec 2009, 10:10 PM

The file get uploaded. But I'm never sure about that because of the timeout.
The speed is also a problem.

I'm using Windows 2003 server. Windows version is not important, the FTP client is.
FileZilla or n/software ip*works FTP component.

I known very well FTP, I wrote a FTP client in C++ (not used here).

I was suspecting a MTU discovery problem for the path, and hence the question about the Win version(so we could troubleshoot further).

How do you find file attachments/upload speeds to FM over HTTP? Is the problem limited to FTP?

If its limited to FTP, can you try an alternate client and see how it goes there.

If you have problems with different FTP clients, can you check FTP uploads to a server other than FM, ie., if you have access to one?

If not limited to FTP, how do you find large attachment uploads to say gmail over HTTP?

I reproduce the problem on every machine I have.
I never play with MTU and leave the default value.

On a dedicaded Windows server in a data center (yes I have a server ip = xtware.com)
A 10Mb file with FileZilla => download time from FM : less than 2 second.
Upload time (I have a 100MB symetric connection) 80 Kb/s, speed indicaded by lastest FileZilla version (3.3.0.1)

On file sharing web site http://demo.ovh.net speed is normal (symetric).
On FTP backup server provided by my hosting company speed is normal.
