Method 'UploadFile' of object 'ISDTPConnection' failed

Post by donj91711 » Mon Mar 23, 2015 9:14 pm

I can connect to the client OK, but when I try to upload a file I get: Method 'UploadFile' of object 'ISDTPConnection' failed
 
The code:
Public objSSH As sfFTPLib.SSHConnection
Call objSSH.Connect
Call objSFTP.UploadFile(FileName, FileName, RestartLow, RestartHi)
 
The log:

This used to work fine until I had to move to a new server running Windows 7 which caused me to load the latest version of SmartFTP library.
Any thoughts?

What do you see in the SFTP log? You have to set the LogFile property of the SFTPConnection.
 
And does it work if you use the SmartFTP client?

I turned on the SFTP log and it shows:
2015-03-24T14:32:11 Uploading file to "<filename>.zip".
2015-03-24T14:32:11 StartPosition=0, EndPosition=0.
2015-03-24T14:32:11 2 File not found
 
I've tried it with the full path name. It seems like it can't see the file in my local directory.
 
When I tried it with SmartFTP client is shows:
[14:34:58] 1>257 "/toSFG/" is current folder.
[14:34:58] 1>TYPE A
[14:34:58] 2>150 Opening BINARY mode data connection for MLSD /.

[14:35:17] 1>550 No such file or folder.
[14:35:17] The operation has been added to the Transfer Queue. Check the Transfer Queue for the status.
 
It then adds the file to the transfer queue, and it is uploaded a few seconds later. I'm not sure what to make of it. Is it saying it can't find the file on my local drive, or is it saying it can't find the folder /toSFG/ on the host?

You are mixing things up. In SmartFTP you use the FTP protocol.
 
>2015-03-24T14:32:11 Uploading file to "<filename>.zip".
When you upload a file to a SFTP server you always have to use the fully qualified path (absolute path) because SFTP doesn't have a concept of a "working directory".
 
>2015-03-24T14:32:11 2 File not found
The error comes from the server.
