Deactivating STAT command

Hello,

I have a simple question...

Is it possible to deactivate the STAT command the FTP client execute on the server after each file is uploaded? This "glitch" is bugging me a little. I cannot navigate the server folders throught the remote browser while the transfer queue is uploading my files. The 2.5 version was not doing that, on the exact same server I am uploading now. Can we turn off the command, or its "integrated" in the software source code?


Thanx for the answer!

No one have an idea? Or at least something on which I should look at?

A server configuration, or just a the software config?


Any thoughts would be appreciated...

What problems do you have with the STAT command? The client doesn't just send it for fun It uses it to get the information of the file(s).

I have a problem with STAT command when using proxy server.
When I use proxy the reply for STAT command is "502 Command Not Implemented"

The problem I'm having is that the queue is never uploaded, it just keeps retrying.
Without proxy the uploads work fine but from my work I must use this proxy.
There is same problem with the FEAT command so I have disabled it.

Any fix?

Post the log from the transfer queue.

I found the problem!

In my default settings, the option "Verify Integrity" was Enabled. It was the option that was sending STAT command to the server, to check the uploaded file integrity. I deactivated it, and its now working as I was expecting!

Thanks! Hope the solution will help other people!

Here are the logs.
What I have done is that I'm trying to upload two files.
When the queue is started the first file is uploaded to the server but second one is not.
The second will be sent when the queue is stopped and started again.

Log for the first file

As the second log says you have no permissions to upload to the server.

I thought that I had mentioned this but I guess I wasn't so clear.
I have no problem uploading files if I do not use the proxy!
And even with proxy I can upload one file at a time but not with the queue.
So I do have rights to upload files on the server and also the proxy lets me upload files but not with the queue.

So why is that?

Just one more thing.
Just tried with the version 2.5 (with the same settings).
With the queue there is the same problem than with the version 3.0.
But with direct transfer I can upload multiple files just fine.
Now that 3.0 doesn't have "direct transfer" it is a bit difficult to upload multiple files from behind the proxy.

You may want to purchase a license at:
https://www.smartftp.com/buy.php

And our technicians will be able to look at your problem.

Regards
Mat

OK, Thanks.

I might buy a license because I think that you have a great product here for my purposes but not just because by buying it something might be fixed for me. But I do understand the reasoning, though.
This is not that big of a deal for me, I might not be using this proxy tomorrow anyhow.

I just let you have this information so you may use it in your development and improve your product, or not.

Thank you for sharing the information about your proxy. Your proxy is restricted as it doesn't let you use certain commands (SIZE, MDTM, STAT, PASV, etc). There is nothing an FTP client can do about this since the restrictions are on the server/proxy side.

Regards,
Mat

Yes I know, proxy "configurators" can be so paranoid.
So if nothing can be done why to get support by getting the license.
Sorry, had to say that.

Well, the FTP client can do so much that with 2.5 it is possible upload multiple files but not with 3.0, event with the restrictions in place.

Hi Mat,

I’m getting back to this matter.
Now I also have valid license for SmartFTP so that is also taken care of.

This problem really confuses me.
I know that the root cause for this is with the proxy server but there is something with SmartFTP that it could do differently.

Why do I think so? Well, This problem does not occur with SmartFTP 2.0.
With the same connection setting I can transfer files in SmartFTP 2.0 by drag and droping and also using the Transfer Queue.

With SmartFTP 3.0 the first file in the queue is sent but it fails with the second one. If I would increase the number of Workers it might send more files before stopping.
When I stop and start the queue again it will send the next file.

So, the proxy does allow me to transfer files (i.e. I do have rights to do it).
Maybe it is the MFMT or SITE UTIME commands that make the proxy to go “User Access Denied” mode. Those commands are not used in 2.0 version. At least, they don’t show up in file transfer logs.
Also, I have seen in logs that before the “connection” goes to “User Access Denied” mode it does successfully execute command you listed.

Thank you for sharing the information about your proxy. Your proxy is restricted as it doesn't let you use certain commands (SIZE, MDTM, STAT, PASV, etc). There is nothing an FTP client can do about this since the restrictions are on the server/proxy side.

A workaround for your situation would be to disable the "[x] Reuse Connection" in the menu: Tools->Settings Transfer Queue. This way SmartFTP will open a new connection for each item in the transfer queue.

Regards,
Mat

Another solution would be to disable the [x] Keep File Time option in the Favorite properties. To to do this:
1. Menu: Favorites->Edit Favorites
2. Locate your favorite
3. Right-click on it and select Properties
4. Go to the Transfer->Files dialog
5. Disable all Keep Alive options.

Regards,
Mat

Mat,

Thank you for your solutions.
They both seem to work fine for me and I'm quite happy how the program works for me now.
This is exactly the kind of help I was hoping for.

PS. I must say that I saw your original reply, which you deleted, and I was quite disappointed with it.
Glad you changed it.

Case solved.
