Hello Team,

We are getting the below exception while uploading a file using PutFile method.

=====================================================================

In this FTP, we don't have an access to get the list of files/folders for this user.
With out verifying/getting the list, just we need to upload a file in ftp's root folder. Please help me how I can achieve this. We can put the file using Windows File Explorer.
Please help me to resolve this error.

Thanks & Regards

Answer 1

Hello,

the Ftp.PutFile method is suitable for this purpose. it does not perform any listing prior to the file upload.

Are you able to upload the file to the FTP server root with the short code below?

Ftp client = new Ftp();
ftp.LogWriter = new Rebex.FileLogWriter(@"C:\logs\ftp-log.txt", Rebex.LogLevel.Debug);
client.Connect("ftp2.ftccc.net");
client.Login("ftp2.ftccc.net", "your-password");

// upload the local file to FTP server's root
client.PutFile(@"C:\data\SALCINV_20150915152617.AMI", "/SALCINV_20150915152617.AMI");
client.Disconnect();

Please give it a try and let me know whether it works.

Hello,

I have tried with the same code which you provided. Issue is still reproducing. See below error log.

================================================================

Now we are able to upload the file from both FileZilla and Windows File Explorer.
We are having this issue with only Rebex PutFile method.

Please help me to resolve this error.

Answer 2

This is really strange error message. Perhaps the server doesn't allow write access to the FTP root folder, or it doesn't like absolute paths. Can you please try the following code?

The code will upload the file into current working directory. You can determine what is your current working directory using the client.GetCurrentDirectory() method. To change working directory use the client.ChangeDirectory() method.

If it still doesn't work. Please send us FileZilla log for comparison.

Ftp client = new Ftp();
client.LogWriter = new Rebex.FileLogWriter(@"C:\logs\ftp-log.txt", Rebex.LogLevel.Debug);
client.Connect("ftp2.ftccc.net");
client.Login("user-name", "user-password");

// change working directory if needed
//client.ChangeDirectory("/");

// upload the local file to current working directory 
// at the FTP server
client.PutFile(@"C:\data\test123.txt", "test123.txt");
client.Disconnect();

Thanks for your reply Lukas.
I tried the same code to get the current directory and change the directory.
The current directory returns as "/ftp/incoming". While changing the directory also we are getting the same error. Please see the below error log.

Please help me to resolve this issue. Our customers are asking to fix this asap.
Because the users are able to export the files by using File Zilla and Windows File Explorer. In Rebex only we are getting this issue.

Please help me to resolve this issue asap.

Hello and thank you for the FileZilla log!

From the log you sent, we can see that FileZilla client uploads the file into the "/ftp/incomming" directory, not into the root directory ["/"]  where you obviously do not have sufficent rights.

Achieving the FileZilla behavior with Rebex FTP component is quite simple, just try the below code snippet:

    Ftp client = new Ftp();
    // connect and login

    client.ChangeDirectory("/ftp/incomming");

    // upload the 'file.txt' into the current directory
    client.PutFile(@"C:\data\file.txt", "file.txt");

Let me know whether you are able to upload now.

---

Thanks for your reply.

We can see the same current directory "/ftp/incoming" in our Rebex log also.
If we connect to this FTP with the given credentials, by default it connects to the "/ftp/incoming" directory.

I am going to check the code which you suggested.

But my doubt is that necessary to change the directory? Because in Rebex also we are getting the same current directory.

---

I am facing the same issue even after executed this code. See below Rebex error log.

After you login into any FTP server, the server changes you into what we call "home directory". This is the directory that you get if you call Ftp.GetCurrentDirectory() after the Ftp.Login method.

The "home directory" can be the actual root (e.g. "/") but it can also be some other directory. In your case it seems to be "/ftp/incomming".

So if you are already in the "ftp/incomming" directory after logging in, then you do not have to call the ftp.ChangeDirectory method.

So your code would be:

     Ftp client = new Ftp();
     client.Connect("server");
    client.Login("user", "password");

     // upload the 'file.txt' into the user's home directory
     client.PutFile(@"C:\data\file.txt", "file.txt");

Yes you are correct. The same code I am using. But I am facing this issue.

---

in your above log I can see that you are still calling the PutFile method with a bad argument.

2015-09-21 18:11:35.290 INFO Ftp(5)[1] Command: STOR /test10.txt

make sure that the second argument does not start with a leading slash "/". If you include a leading slash into the remoteFilePath, then it will instruct Rebex FTP to upload into the actual root where you do not have access!

So this will work and upload into the current directory:

    client.PutFile("file.txt", "file.txt");  // works

this will not work with your server:

    client.PutFile("file.txt", "/file.txt");  // uploads the file into the FTP root directory - causes no access exception with your server!

---

So it is the slash that is causing troubles. Please check on that and let me know.

Great.....
Issue is fixed. Thanks to identified the issue.

Actually we have a common method to upload the files into FTP. there we are passing Empty value for this FTP. Because by default File Zilla also connects to the same folder with out changing the directory to "/ftp/incoming".

So we have also tried like the same.

Now issue got fixed.

Thanks alot....

Ok, I am glad to hear that. Thank you!

---

May I know how the FileZilla and Windows File Explorer are handling this?

If we know the generic fix, it is very useful for other FTPs.

---

I don't know what you mean by generic fix... If your requirement is upload to home directory, I already provided a simple code to achieve this with Rebex which will work with any FTP server.  If apart from this, you will also need to upload to some other directories (e.g. to "non-home directories") then you have to know what is the target directory for each FTP server. And you will have to have a parameter / config value / GUI pick in your program that you will use to determine where exactly you need to upload.

For sample implementation of a GUI FTP client, please check our Ftp WinformClient sample (http://www.rebex.net/sample/ftp-winform-client-classic/). The sample source code comes as a part of your Rebex FTP/SSL package.

And by the way, could you please share your order ID or the email that you used to buy your Rebex FTP license? Unfortunatelly, I was unable to find your order in our system.

---

Thank you.

We have a different email id which has Rebex license. Unfortunately we missed the password. So we created an anonymous user in Rebex and created this ticket.

---

Ok, no problem, but what is the registered email? You can send it to us privately to support@rebex.net and I will associate the forum account with your license then. Thank you.
