MLST used instead of MLSD

2013-01-28 15:24

Hello,
We are trying to get a file from FTP server (implicit SSL) using .Net

We are using

SessionOptions sessionOptions = new SessionOptions
{
Protocol = Protocol.Ftp,
HostName = "xxx.xxx.be",
UserName = "xxxxxx",
Password = "xxxxxx",
PortNumber = 990,
FtpSecure = FtpSecure.Implicit,
SslHostCertificateFingerprint = "54:8d:3c:6b:7f:90:ec:f9:2a:55:43:f4:6b:93:64:c2:be:4b:62:87"
};
using (Session session = new Session())
{
session.Open(sessionOptions);
string path = "/ZTH/Files/Current/437/Update/ZTH.zip";
session.GetFiles(path, System.IO.Path.GetTempPath()).Check();
}

WinSCP is using MLST which is not supported by the server.

. 2013-01-28 15:13:00.644 Listing file "/ZTH/Files/Current/437/Update/ZTH.zip".
. 2013-01-28 15:13:00.644 Retrieving file information...
> 2013-01-28 15:13:00.644 MLST /ZTH/Files/Current/437/Update/ZTH.zip
< 2013-01-28 15:13:00.659 502 Command not implemented.

Using WinSCP GUI, all is fine, MLSD is used.

Any help?

First, I believe the specifications do not allow the server to support only one of MLST/MLSD pair.

Anyway, I hope you can workaround that by using:

TransferOptions options = new TransferOptions();
options.FileMask = "ZTH.zip";
session.GetFiles("/ZTH/Files/Current/437/Update/", System.IO.Path.GetTempPath(), false, options);

Hello,

Thanks for your suggestion, but the workaround isn't working. I don't undestand why the .Net assembly version is using MLST while this command is not listed in the FEAT list of the server. When I use the full WinSCP (GUI version), everything is OK, MLSD is used, not MLST...

Here is the full log of the .Net assembly version:

It is working when adding * at the end of the remote path... Thanks.
