FTP DLX Loops on SIZE command when Getting a file (wodSFTP / wodSFTP.NET / wodSFTPdll)

I'm working on a program that connects to a server and automatically downloads some files. I can connect, put files, and list directory contents, but when I get a file the program appears to hang.

I turned on the debug file for the component and examined its contents, and found that eventually the component attempts to get the size of the file I have instructed it to download, and it gets stuck in a loop, repeatedly sending the SIZE command to the server.

The rest of the log is available if it will help.

[code]

Hi,

What version of wodFtpDLX are you using? Also, are you using ActiveX or .Net version?

Did you try our samples? Does the same issue occur with them too?

Regards,

I am using the component in Delphi using COM. I have successfully used the component to connect to and perform similar tasks on other servers. I am confident that the problem is not my use of the component.

It seems to be a combination of the component and the server. I can connect the component to other servers and download files. I can connect other clients (Filezilla) to the server that I am having a problem with.

The server claims to be running WS_FTP Server 6.1:
220 mom01.secure.maine.gov X2 WS_FTP Server 6.1(74375000)

The last thing that is called before the loop occurs is

FTPobj.GetFile('C:path10382027.01', '/users/TR10382/tr10382o/10382027.01');

'C:path10382027.01' and '/users/TR10382/tr10382o/10382027.01' are in variables. When I look at the files with a client like Filezilla, the remote file is there. The file does have a size of 732 bytes as the log shows. The local directory does exist.

Hi,


I have just tried to duplicate your problem in Delphi using WS_FTP 6.1 server but unfortunately didn't have luck.

Which version of wodFtpDLX you are using?
[code]ShowMessage(FTPobj.Version);[/code]
What happened when you set Passive Property to True?

The version is reported as '2.6.3.275'. I have been using Pasv mode enabled. Data transfer seems to be working fine as I can list the files in a directory, and I can put files on the server, Its only the Get that fails.
