posted July 19, 2006 4:50 PM I'm having a problem which I've reproduced by: I downloaded/installed the latest SSL Tool as of today. I downloaded/installed the latest Filezilla client as of today at http://sourceforge.net/projects/filezilla/ I ran the sample code at C:\Program Files\PowerTCP\SSL Tool\Samples\Vb6\SecureFtp\Server with no changes. Windows XP, Windows Firewall off. Norton worm protection off, auto-protect off. Filezilla set to passive mode. I try to log onto the sample FTPS server with Filezilla, both running on the same machine. Filezilla 2.2.9 used to work, but 2.2.22 and up fails at the file listing. Could you verify that this doesn't work, or give me the proper settings to make it work? Having it fail at the file listing is usually a sign of firewall issues, but I've gone to great pains to try to make sure that isn't an issue for this test. |

posted September 8, 2006 10:16 AM I know why this is happening and I can give you a workaround if you are still interested. The problem is that FileZilla sends the PBSZ and PROT commands which we do not support by default. When we respond to the PROT P with a '500 Unknown command' error, I believe that FileZilla is assuming that our data connection will be in clear text and is therefore not establishing the connection properly. To remedy this, all you have to do is handle the commands in the server's Command event like so: Private Sub SecureFtpServer1_Command(ByVal Cmd As String, ByVal Request As DartSecureFtpServerCtl.IRequest, ByVal Response As DartSecureFtpServerCtl.IResponse) If Cmd = "PBSZ" Then If Request.Parameters(2) = "0" Then Response.Status = 200 Response.StatusText = "PBSZ=0" End If ElseIf Cmd = "PROT" Then If Request.Parameters(2) = "P" Then Response.Status = 200 Response.StatusText = "PROT command successful." End If End If End Sub |
