WsftpSDK Deployment problem

Tejaswy_Mathad — Wed, 29 Apr 2009 09:20:16 GMT

Hi,
We are using WSFTP Secure SDK 8.1 to build a C#.Net 2.0 application to automate file transfers. The application is working fine on the development machines (Windows XP Professional SP2). But on the server (Windows Server 2003 Standard), the application doesn't run. The eventviewer shows the following message:

Faulting application gems.sftp.exe, version 1.0.0.0, stamp 49f830d8, faulting module unknown, version 0.0.0.0, stamp 00000000, debug? 0, fault address 0x0489f524.

Note: We have deployed WsftpSDK.dll, msvcp71.dll and msvcr71.dll in the same directory and registered WsftpSDK.dll using regsvr32 command.

Any help to resolve this issue is much appreciated.

Thanks,
Tejaswy Mathad

Problems with FTP/SSL (AUTH SSL) connections

jmac — Wed, 23 Aug 2006 11:57:37 GMT

OS: Windows XP SP2 and Windows Server 2003

DEVL: Using Visual Studio 2005/ VB 2005

SDK Version: 8.1

I wrote a database centric program that "wakes up" every 10 minutes and processes any transfers due to run. The program handles regular FTP transfers without any issues I have several FTP processes that have been running on a Win 2003 server for over a week. (In Example, one transfer process FTP's 17 files from our network to a unix server every 10 minutes).

When I attempt to use the the same code to make repeated secure connections to our WsFTP Server using a FTP/SSL (AUTH SSL) my program will abend. I had the secure connection scheduled to run every 10 minutes - it would successfully run several times then it would abend with a DEP violation or AccessViolationException.

I have been playing with this connection in my development environment, making several minor code changes but I can't seem to get it to work consistantly

I setup the transfer to upload 1 file every 10 seconds to wsFTP Server using FTP/SSL. The process ran successfully for just over an hour - then died with a win32 error.

I then setup the transfer to upload 1 file every 30 seconds to wsFTP Server using FTP/SSL. The process ran successfully for 22 minutes - then died with a AccessViolationException (Attempt to read or write protected memory. This is often an indication that other memory is corrupt)

I see there were issues with ssl connections that were corrected in release 8.1. Are there still know issues?

I can provide psudeo code - perhaps someone can point out what I am doing wrong...

SFTP using SSH key?

alexi — Thu, 11 Dec 2008 09:57:10 GMT

Is it possible to use an ssh key instead of a password to connect to an SFTP server? (the option exists in the WSFTP client, but I can't find it in the sdk)

Connection Dead error for ChangeDirectory command

DaveD — Thu, 08 Oct 2009 13:31:56 GMT

I have a ftp/SSL (Auth SSL) connection to a trading partner. Up until a week ago I could successfully connect to their site using both the SDK (my code is written in C#) and the WS_FTP Pro GUI. After I connect to the home folder, there are 2 folders named "in" and "out" for transferring files.

Last week they sent me an email with a new password. They claim this is the only change they made. WS_FTP Pro still works fine. I can login and navigate to the 2 folders and transfer files.

With the SDK I can login (at least it appears to succeed), but when I issue the ChangeDirectory on the WsftpConnection object I get an error 61, Connection dead. Before I contact the trading partner to see if they can troubleshoot this, do you have any suggestions as to what can cause this? I have made no changes to my C# code, and my connection to other trading partners using SSL still works fine.

Thanks in advance.

Using Java with WS FTP SDK

cameronp — Wed, 02 Sep 2009 11:37:06 GMT

My company has been using software that was written in VB for a number of years. The software works fine now but is starting to become very dated. That being said we are looking to write new software to handle all of our file transfers (our company works with Blackboard services and ftp). We want to write it in Java. However, we have not been able to find any resources on using WS_FTP SDK with Java and were wondering if there is any support at all for the language.

Transfer mode for append

Jim @ Wawa — Fri, 03 Apr 2009 15:05:40 GMT

I am programming in VB using the SDK to push several files into an appended file on a VAX. How can I control whether the file transfer is binary or Ascii if I am doing an append?

Create Connection not timing out

wladd — Thu, 19 Mar 2009 15:36:55 GMT

We are having some issues connecting to an sftp site. We know that we occasionally have firewall issues on either our end or theirs. We need a way to cleanly handle the inability to create a connection. Below is the relevant section of code.

ErrResult = Nothing
pApi = New WsftpApi
pApi.DiagnosticLog = False
pApi.TimeStampLog = False
pApi.PassiveMode = Passive
pApi.CommandTimeout = 12

Try
pConn = pApi.CreateConnection(FTPSite, UserID, Password, FTPType, FTPPort)
'FTPType = SFTP {4}, FTPPort = 22
Catch ex As Exception
LastMessage = pConn.LastServerResponse
ErrResult = ex
Return False
End Try

If (pConn Is Nothing) Then
...
End if

When we are able to connect there are no problems. However, if we are not able to connect (forced in this case by changing the userID so it isn't valid) the application hangs on the pApi.CreateConnection. I have placed breakpoints at "LastMessage = ..." and "If (pConn ..." and neither of them are being triggered, while the breakpoint at "pConn = ..." is.

The problem does not occur when repeating the same failure mode using an FTP site. The timeout occurs and we are able to trap and handle the issue. (FTPType = FTP {2}, FTPPort = 21)

For some reason the timeout is not occurring. We are all set to capture the timeout and fail cleanly, but instead the application hangs indefinitely. Any help with this would be greatly appreciated.

SSH buffer size not multiple of blocksize

Jim @ Wawa — Tue, 07 Jul 2009 09:54:16 GMT

Anyone have experience with large files? I have a job that runs weekdays, pulling data from a bank to our SAP system. The file transfers fine, decrypts OK, but when we send it to our SAP host it fails every Monday. The only significance I can see to the day is the the file is about twice the size on Mondays as it contains Friday and Saturday data.

Our most recent monday file (which failed) was 1.17 GB, and Thursday's was 750MB.

The error message is (SSH buffer size not multiple of blocksize).

The file transfers successfully using the WS FTP Professional GUI, but fails using the SDK DLL.

FTP over SSH connection with predefined sites?

tomdejaeger — Thu, 16 Apr 2009 09:25:09 GMT

Hi,

I'm trying to use predefined sites, which are made in the WSFTP_PRO client program - under the site manager - in my SDK script.

So far I've tried something like 'Sites!PRD!GIESECKE(name of site)' when using an pAPI.Connection object, but so far, no luck.

Is there a way to use an predefined site (in WSFTP_Pro) in a SDK Script. The real question is, how do I make a connection over SSH to a site that uses only a username, but no password? Instead, SSH keys are uses between both sites.

Regards,:ermm:

Multiple Downloads

drmorrowjr — Sun, 29 Mar 2009 18:25:09 GMT

I would like to be able to download multiple Items at the same time. I thought I saw some documentation in the API or on the forums how to do it but now I can't find it. Something about adding a handler in the "nResumeFrom" variable I think.

Or is the only way to do it, is by creating multiple threads with a unique connection on each thread as I am doing it now.

Connection Dead

drmorrowjr — Wed, 25 Mar 2009 13:06:11 GMT

I am using a simple ftp site and I am having quite a bit of difficulty connecting to it here is the code I am using.

Dim pApi As WsftpSDK.WsftpApi
Dim mWSFolder As WsftpSDK.WsftpFolder
pApi = CreateObject("WsftpSDK.WsftpApi")
pApi.LogToFile(True, My.Application.Info.DirectoryPath & "/TestLog.log")
pApi.DiagnosticLog = True
responseStr = pApi.SDKVersionStr
Dim x As WsftpSDK.WsftpConnection
x = pApi.CreateUrlConnection("ftp://MyIP/:MyPassword@MyUser")
' x = pApi.CreateConnection("ftp://MyIP/", "MyUser", "MyPassword", WsftpSDK.WsftpConnectionTypes.WSFTP_CT_FTP, 21)

responseStr = x.GetCurrentDirectory
responseStr = pApi.GetErrorString(x.LastError)

1st the second type of connection just returns nothing.

2nd GetCurrentDirectory returns nothing and yes there are folders inside that directory but no files I have tried placing a directory name in the connection and I have also tried using the ChangeDirectory method

3rd when I get the error string it tells me "Connection Dead"

After everything is complete I open up the log file and the only thing it says is "Connection Succeded"

So am I doing something wrong here.

Find the path of a file in a folder

manickam.arunraja — Fri, 20 Feb 2009 05:19:12 GMT

Hi All,
Can any of you elaborate on how to find the path of a file in a folder or sub folder.
There am providing a rule or a trigger during file upload. I have a site created using WS_FTP server version 7. And the site can contain any number folders and sub folders in it. When i try to upload a file in any one of the folders, i have trigger exceuted where that particular trigger would transfer the file to another location. The problem here is that i dont have a static path. I may upload the file in folder or sub folder. so i need a command which would find the path where excatly the file was uploaded. so that i can get the file and move it to another loaction. Can any one provide me a code or command to do that.

Thanks in advance

Error 841b0000 receiving sftp packet

pvanatta — Fri, 11 Jul 2008 17:05:03 GMT

I have been using the Secure SDK for a few months without any trouble until a few days ago when the GetCurrentFolder method stopped working. Whenever I issue the GetCurrentFolder("*") command now I get this:

The operation completed
Getting Dirlisting
*** Zlib Transform(Decompress) reallocating output buffer from 24576 by 4096
*** Zlib Transform(Decompress) reallocating output buffer from 29696 by 4096

# transferred 0 bytes in 0.625 seconds, 0.000 Bps ( 0.000 Bps), transfer failed.
Error 841b0000 receiving sftp packet

From reading other posts in this forum it possibly is caused by too many files or too large of files in the directory I'm trying to list. This could be a real possibility for me, since we just started to heavily use the software application I wrote and one of the things it does it upload files automatically, so the number of files on the remote size has grown.

Does anybody have any ideas? Is this a bug? Is there a fix? I'm using WS_FTP-8.01-2005.05.25, which is the most recent version.

Thanks, Paul

Directory listing on SFTP site???

kboominathan — Thu, 31 Jan 2008 13:38:08 GMT

Hi all,

Can any of you elaborate on how to scan through the files on a remote directory using filemask. For example If I only wanted to get all *.csv files from a remote directory on an SFTP site.

The following code always lists all the files from the remote directory, where as I need only *.csv files.

pConn = pApi.CreateConnection(str_FTPlocation, str_FTPUsername, srr_FTPPassword, WsftpConnectionTypes.WSFTP_CT_SFTP, 22)
pFolder = pConn.GetFolder("*.csv", str_FTPDirectory)
filecount = pFolder.Count

Is this a bug or am I doing something wrong? Please share your thoughts.

Thanks

SDK Disconnection problem

claimshop — Tue, 09 Sep 2008 12:54:18 GMT

There used to be a topic on this subject, but it seems Ipswitch removed it - I wonder why...

Nonetheless, it appears to be a confirmed bug with the SDK version 8.0 or 8.1, and it's been fixed in a later version. When you issue a disconnect() call, the connection doesn't actually disconnect from the host. Connections can then pile up and end up looking like a virtual DOS attack.

We paid our $1000 for the SDK, we had an active Ipswitch service agreement WHEN IPSWITCH KNEW about this bug, but we never got an upgrade as stipulated as part of the service agreement. I've asked on this forums for someone to contact us, but nobody has. There's no way to contact a human at Ipswitch without a SA, and we let that lapse, as the support was useless, and I'm not going to waste my time on the phone waiting to talk to a person. The free SDK download is the same old buggy version from 2005.

I'd like the upgrade we're entitled to, just as a matter of principle. We've already switched to another SFTP product (EnterpriseDT), since WSFTP wasn't reliable. In fact, the SFTP disconnect problem could have gotten us in a lawsuit, as a vendor accused us of perpetrating a D.O.S. attach on their server! Watch out.

Object creation error - Ipswitch WS_FTP Pro SDK 8.1

cjusanc — Sat, 16 Aug 2008 03:08:02 GMT

Hi to all.

I'm stuck on this part of our code where we use "WsftpApi apiConnection = new WsftpApi();" to create a new object.

We have two major modules, Automation (windows service app) and UI (forms). These modules uses a common DLL (AutomationDLL) where "WSFtpSDK.WsftpApi" interface is included as reference. What's really weird about this is, we've tried running both modules a million times in XP Pro SP2 operating system and haven't encountered any problem at all (sending the files to the target server). But when we tried it on Windows Server 2003 SP2, that's the only time we encountered the problem - "Exception creating WsftpApi" and this only happens in the Automation part. In UI part, everything works fine.

any insights/suggestions/help from you guys are highly appreciated.

Thanks.

SSH Connection object failing - FTP object works

ljkrauss — Mon, 21 Apr 2008 18:25:15 GMT

I have a test program that is trying to make an SSH connection:

bool pbVal = false;

WsftpApiClass api = new WsftpApiClass();

// WsftpConnection conn = api.CreateConnection(tbURL.Text, tbUID.Text, tbPWD.Text, 2, 21); --- FTP works

WsftpConnection conn = api.CreateConnection(tbURL.Text, tbUID.Text, tbPWD.Text, 4, 22); --- SFTP doesnt

pbVal = conn.PutFile("",tbFileName.Text,".","tada.wav",0,0);

MessageBox.Show(pbVal.ToString());

Using the WSFTP client with SSH from the same workstation I am able to connect successfully.

Second question:

I found this "WsftpApiClass" class in the forums but nothing in the doc, object model, etc. it was "WsftpApi". Both seem to work. Any details?

Thanks. Larry.

Access violation error

Michaelk — Fri, 29 Feb 2008 12:22:57 GMT

When sending or recieving a file using the sdk I am getting a win 32 unhandled exception of Access Violation. The problem seems intermittent as when I send small files it succeeds most of the time without the exception coming up. If I use dos FTP or the client software I am able to send these files to the destination with no issue. Any assistance would be greatly appreciated.

FTP SDK Directory List under IIS

vasimo — Tue, 19 Feb 2008 14:56:56 GMT

Running on a 2003 web server with IIs 6.

A desktop application brings back the correct folder.count value as well as the item data from the directory.

The same code running under IIs brings back a folder count of zero. The log shows the same byte count retrieved as the desktop app but the data is not available.

Has anyone seen this behavior?

Following is the ASp code used.

'on error resume next
Dim m_SessionLogs
dim Datafield

m_SessionLogs = "*****************************" & " "
m_SessionLogs = m_SessionLogs & "Start Directory List" & " "

Dim pApi
Dim pConn
Dim pFolder
Dim pLocFolder
Dim pItem

Dim wkConnStr
m_ServerDir = "/Telecdat/Vics"

wkConnStr = "ftp://ABC123:ABC123@158.100.100.108"

Set pApi = CreateObject("WsftpSDK.WsftpApi.1") 'create object name

Set pConn = pApi.CreateUrlConnection(wkConnStr) 'Use the URL text field in this example
If pConn Is Nothing Then 'If a connection error encountered
m_SessionLogs = "Connection error: " & pApi.LastError() & " " & pApi.GetErrorString(pApi.LastError()) & " "
End If

m_SessionLogs = m_SessionLogs & "Connected." & " "

Set pFolder = pConn.GetFolder("*", m_ServerDir)
If pFolder Is Nothing Then
m_SessionLogs = "Change Directory to " & m_ServerDir & " failed. " & pConn.LastServerResponse & " "
End If
m_SessionLogs = m_SessionLogs & "Change directory to " & m_ServerDir & " succeeded." & " "

m_SessionLogs = m_SessionLogs & "Folder = " & m_ServerDir & " "
m_SessionLogs = m_SessionLogs & "pFolder.Count= " & pFolder.Count & " ********* "

Datafield = Datafield & " Session logs: "
Datafield = Datafield & m_SessionLogs

ekgurney — Thu, 14 Feb 2008 10:51:57 GMT

I am connection to a WS_FTP SFTP/SSH server. I need to write over an existing file. That file is set to read-only. How can I change the attributes of the remote file? I've tried the ChangeAttributes command, that doesn't work.
