Problem getting Listing for UNIX Type: L8 Server (wodFtpDLX / wodFtpDLX.NET)

I'm currently have trouble listing files within a specific directory for a UNIX Type: L8 server. I know 3 files exist, because I can see them with 2 other Ftp tools.

Following are log files from those 2 other tools, and one with wodFtpDLX.net.

Any idea what the problem may be?

Hi Dave,

If it works with other applications, it should work with us too. Perhaps you could try to set FirFormat Property to Ftp1.DirFormat = WeOnlyDo.Client.DirFormats.UNIX

If this doesnt work, is it possible for us to gain access to the server?

Can you contact me at techsupport@weonlydo.com

Regards,
Damba

Sorry, This external FTP server is also limiting incoming connections by IP address.

I've tried all the different DirectoryFormats and have even tried using your demo apps. None of them are displaying the 3 files.

Dave,

Did you try the same code on any other server? does it work with them?
If yes, i noticed in second log that you set Passive to False. Can you try it with wodFtpDLX.Net?

Regards,
Damba

I tried as you suggested, PASV=false but no luck.

I'm not getting anything back from the Ftp1.ListItemsEvent.

Hi Dave,

Please try to use ListParams Property before calling Connect Method. You need to set value of ListParams Property to .

Here is example:
---------------------------------
dlx1.ListParams =
---------------------------------

Now, when LIST command is executed it will send only LIST without parameters. By default wodFtpDLX.NET send LIST -al. Maybe this will help you.

More help for ListParams Property you can find here:
http://www.weonlydo.com/FtpDLX.NET/Help/WeOnlyDo.Client.FTP~WeOnlyDo.Client.FtpDLX~ListParams.html

Hope this help.

Regards,
Drazen

I am already setting ListParams = .

I wonder if there is an error being thrown from the CWD, and that the list command is not even being sent? Wouldn't the list command typically show up that it is being sent?

This problem might also be corrected with another issue I'm trying to work through with Kreso, regarding MVS and not forcing a CWD command to happen every time. The logic I would like to be implemented, is if FTP1.RemotePath is already = to the RemotePath being sent into the ListDir function, then skip the CWD command and just do the list. That just might also correct the problem here?

Hi Dave,

PASV or PORT commands are not visible. You need to call ListDir Moethod but I don't see it on log.

Please send us complete FTPReply.

Here is how:
-----------------------
Debug.Print(Args.Command + + Args.ReplyText)
-----------------------

You can send us also code snippet.

Regards,
Drazen

Here is the log again, showing you exactly the commands being sent and received. The top one is the problem one where the LIST command is not being sent. The bottom log is to a different server and you can see the LIST command is being sent. Maybe the problem is your code doesn't know how to handle <virtual directory>?

Again however, my proposed logic would still hold true for this example. FTP1.RemotePath is already set to <virtual directory> and I'm also calling Ftp1.ListDir(<virtual directory>), so because they are both equal, I just want it to do a LIST. Please don't force another change directory, it's already in the right place.

Dave,

You can try something like this in PreTranslateCommand Event:
----------------------------------------------
Private Sub dlx1_PreTranslateCommand(Command As String)

If Left$(Command, 3) = CWD Then
Command = & vbCrLf
End If

End Sub
----------------------------------------------

or this:

----------------------------------------------
Private Sub dlx1_PreTranslateCommand(Command As String)

If Left$(Command, 3) = PWD Then
Command = & vbCrLf
End If

End Sub
----------------------------------------------

PreTranslateCommand Event fires before the command is sent to FTP server.

More help for PreTranslateCommand Event you can find here:
http://www.weonlydo.com/FtpDLX/Help/wodFtpDLXLib~wodFtpDLX~PreTranslateCommand_EV.html

You can try it. I'm not sure that you will get successful result. Problem is that we can't connect to your server so my proposal could not give any result.
You can try something else to send for CWD or PWD or other Command in PretranslateCommand Event.

Let us know how it goes.

Drazen

No luck. If I change the CWD command to CRLF, then the next thing that happens is I'm getting disconnected from the server.

Calling Ftp1.ListDir(<virtual directory>)

Ftp1_PreTranslateCommandEvent Args.Command: TYPE A
Ftp1_FtpReplyEvent Args.ReplyText: TYPE is now ASCII

Ftp1_PreTranslateCommandEvent Args.Command: CWD <virtual directory>
Args.Command has been manually changed to crlf. Args.Command:

Ftp1_StateChangedEvent Args.NewState: Disconnected from server
Connection was closed by foreign host.

Interesting, I added error trapping in the DoneEvent and the CWD <virtual directory> command is coming back with an error. Nothing very discriptive (230 <virtual directory>), but the point is it's generating an error and possibly why it's not moving on to do the PORT & LIST commands that would typically follow.

Dave,

Please try to call ListDir on this way (if if you didn't yet):

----------------------
Ftp1.ListDir( /<virtual directory> )
----------------------

Any luck?

Drazen

No luck. Same behavior.

Dave,

I will have to inform Kreso about your problem and we will see what he can do for you.

Please send me also error that is returned from Done Event:
--------------------------------------
Private Sub Ftp1_DoneEvent(ByVal Sender As Object, ByVal Args As WeOnlyDo.Client.FtpDoneArgs) Handles Ftp1.DoneEvent
Debug.Print( DONE: + Args.Error.ToString)
End Sub
--------------------------------------

Drazen

I had it printed out already. :)

***Error*** Ftp1_DoneEvent Args.Error: 230 Args.Description: <virtual directory>

Args.Error = 230
Args.Decription = <virtual directory>

I now know that it sends back an error for every CWD command, even with servers I'm not having any problems with. It's more like an informational message than a true error. Is there any way to change that behaviour, so that only real errors come back through the args.Error & args.descrition for Ftp1.DoneEvent? If not, then can you propose a way a person can put in good error-handling logic?

Dave,

One more thing:

Please go to command prompt and type:

----------------------
telnet your_server_name 21
----------------------

and send us first line returned.

Maybe we can find somewhere your server and duplicate your problem.

Drazen

It returned:

Here are the commands straight from a command-line ftp. Doesn't get much simpler than this and yet this is able to get the directory listing.

Dave,

can we meet online? Can you install http://wippien.com and perhaps VNC on your system so we can access it directly and see this for ourselves? Wippien will make sure connection is secure.

I can explain all you need to do in email.

I need to see this and try few things if I could type on your computer.

Kreso

Yes, that should be fine.

I installed the software and it want's me to create an account.

Maybe you can send the remainder what you would like me to do in email?
