Addon toolkit required to establish an FTP Connection

Hi
I would like to know how an FTP connection can be established using Labview 8.0. I tried to check a few examples for FTP connection .. but it dint open as addon toolkit was not installed ...so i would like to know if the addon toolkit is freely available on NI site or else some links or examples that can help me to establish FTP connectionrequired for my GUI design Application
Waiting in anticipation..
Thanking you.
Regards
Yogan

Hi ,
Could you tell me which example you are referring to ? I can open at my end and let you know .
Meanwhile check this http://decibel.ni.com/content/docs/DOC-3664 for a simple FTP VI . This requires just LabVIEW
Regards,
Pran

Cannot establish a ftp connection to xmldb-filesystem

Hey everyone,
how can I connect via ftp to the xmldb-filesystem ?
I tried the instructions from this website http://www.oracle.com/webfolder/technetwork/de/community/apex/tipps/xmldb-filesystem/index.htm (didn't found an english site, sorry). Now I can connect to the filesystem via "win7 shell ftp", but i cannot connect via "win7 explorer" using "ftp://host:port/foo/bar" or filezilla. Everytime i try i got an errormsg like:
filezilla: cannot read filesystem
and
win7
an error appears :
detail:
200 Type set to A.
277 Entering Passive Mode.... see sreenshot -> http://imageshack.us/photo/my-images/841/ftpg.jpg/
If anyone need more information just ask.

Mariowhat do you see when you try ftp from a Command Window?

Can't establish ftp connection between a Xserve and a PB

We want to use a Xserve (Mac OS X Server 10.4.8) to provide webhosting, but experience problems in establishing ftp connections using a PowerBook (Mac OS X 10.4.8).
On a WinXP-based notebook using the same Internet connection, anything works fine, just not on my PowerBook.
This is what happens when trying to establish a ftp connection (via terminal):
I type: ftp [email protected]
Returns:
220 star1.local FTP server ready.
331 Password required for user.
I provide the password, anything looks fine, get this output:
230 User starenterprise logged in.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp>
Okay, now I want to see what files are in the directory using "dir" command ("ls" brings same result). This output is shown:
502 'EPSV': command not understood.
227 Entering Passive Mode (132,78,123,92,42,115)
Now I can either press CTRL+C to escape or when waiting around one minute, then it states this:
421 Service not available, remote server timed out. Connection closed
On a ftp client software like CuteFTP Mac it shows "Can't open data connection" instead of, but result is the same.
I read through some articles I found here, but nothing compared to my problem. Please help.
I should mention one thing Apple's support told me: Since I have the same username and UID on my PowerBook as well as on the xServe, it could bring problems. However I have then added a new user to my PowerBook, result is the same. And Apple's support left helpless so far.

You said: "Not really answered, the problem persists and I now go on and let
Apple work on it again"
As a native English speaker, I must say (and doubt any would disagree) that
your statement implied: "No one here has actually helped me fix this problem,
and now I'm waiting for Apple to fix it"
Please take care to the word "again" I used; this implies that Apple has tried to solve the issue before but failed (in fact, they stated to call me back, but this is weeks ago) and so I posted this here at the discussions.
Unfortunately I only have access to the "free" support (well, free is not the right word when paying 12 cents per minute for the phone call).
And this means (at least I can speak for the German part of Apple) that operators on the phone look at their knowledgebase and sending articles by e-mail; questions going deeper are resulting in a "we call you back" answer. Sometimes they phone back, sometimes not. Sometimes they are helpful, sometimes (or should I say "in most cases") they just give hints or ask me to investing a nice amount into premium support.
Don't misunderstand me in the direction that I demand assistance from this forum - I'm more than gradeful if I get help (and rewarded this always with giving points), it has saved me several times (many, many, many times) for doing time consuming investigations and making trial-and-error experiences by myself. If I cannot get more assistance, well I have to look elsewhere and so be a bit impertinent to Apple's support. Perhaps it helps
You are right, FTP itself works correctly. It even works fine on the WinXP notebook residing at the same LAN as my PB. Therefore the issue is at the PB's firewall very likely (or a strange relationship between two firewalls which seems not to affect WinXP).
But as you indicate, it makes no sense to lower down security just for doing ftp, especially since SSH works well. However since I have no problems doing ftp sessions with other servers, I would be eager to find the reason why it refuses in this case, even this just means feeding my curiosity
So if I come to new insights, I post them here. But I feel that I'll really need your wishes for luck to solve this problem Let's see...

FTP connection in J2ME

Hi All,
can anyone tell me is FTP connection in J2ME possible or not? If it is possible, how it is possible?
Mahabub

AFAIK at present there is no FTP API's avalable from J2ME/MIDP front that you can use to establish an FTP connection.
Meanwhile I have a pretty easier solution for you. You can use Jakarta Commons Net API's at the App server end to communicate to the intended FTP server by means of Servlet so that you can form an Http response as per your requirements. for e.g.:- you issue ftp command from J2ME client and pass it over http to the Servlet residing in your app server. internally the web-tier component establishes the link to the FTP server and responds appropriately based on the issued commands.
You can also use a telnet client that uses socket communications but the approach mentioned above I rekon would be a feasible one bcause the Usability matters the most when it comes to Mobile applications.
Hope this information helps.

Adobe Dreamweaver FTP connection doesn't work with german "Umlaut" like "ö" in the severadress

Hi
Today I tried to establish a FTP connection to the serveradress "ftp.möbelverwandlung.com", but I get the error message that the program couldn't connect to the host. As Dreamweaver works perfectly with other serveradresses and I managed to establish a connection to "ftp.möbelverwandlung.com" with other programs, I think that the problem is the german "Umlaut" "ö". Did anyone recognize the same problem and does someone know a solution?
Thank you very much for your help

Here is the English translation of your previous post -
Hello Maximilian,
I got a even looked at my provider. Usually there must pay the original domain for the agreed period and agree a new. However, they show a accommodating for so short "duration" of a few hours like you. Try to contact your ISP phone support.

Hans-Günter
Anyhow, I think you have covered the options!

Read only on ftp connection?

Hello!
I tried to establish an ftp connection to a server to upload some files, but I had only read permissions. My friend told me it worked from windows(very annoying!). Yes, I had a Windows 7 Boot Camp installation and was able to transfer the files from there. However I don´t like the idea of having to downgrade system just to do some ftp. The server filesystem was EXT4 and I also downloaded a separate free FTP client from App Store: Still no write permission!
After all, in Mac OS there is an option connect to server using login name and password then why shouldn´t it just work like OS X is expected to?
Thanks for your replies

I doubt it is the filesystem as the FTP server should be handling file IO.
Try in the Terminal. There are several ways you can connect.
It is basically ftp user@host, but you can type man ftp to see a list of ways to add username and password, port, etc. Once in man, type q to quit.
Once you log in, you'll have an ftp> prompt. Use the ftp commands to "put" or "get" a file, and "ls" to see what is there. The rest of the commands are in the man page.
Basic FTP has pretty much been dropped from OS X as it is completely insecure. However, I'm not sure why a third-party ftp client had trouble. Maybe it was how you logged into the server.

FTPS connection to GXS

Hello!
I am trying to establish a FTPS connection to our VAN GXS using these settings/credentials:

FTP connection on mobile device works over wifi but fails over 3G

Hi all,
Hoping someone can help, or has come across this issue.
I am developing a mobile app using flash builder 4.6 with the flex 4.6 sdk. My app needs to transfer files via ftp.
The issue I am experiencing is that the ftp connection establishes and files transfer without a problem when connected via wifi, on both android and ios platforms.
However, when only connecting via a 3G connection on a device, a problem occurs. While I can establish a connection, when I send the USER command, I never receive a response.
A simple view with code to reproduce this issue is listed below. Has anyone come across this problem? I have been searching far and wide but cannot find anything related.
Could this be an issue with Adobe Air or the socket class? I have written equivalent code using the android sdk in eclipse, and a connection to the same server and user details works on both wifi and 3g connections.
Any help would be appreciated.
Thanks.

Probably you need to write your own AIR native extension, which uses the native Android sockets..I have the same problem and I'm just starting writing the extension...I guess there is no other way..At least you test with native android socket and you confirm is fine, so we know it should work

Need help to Configure FTPS connection for File Sender Adapter

Hi,
I want to Configure, FTPS connection (Secured Connection) for File Sender Adapter. Could anyone please guide me, what Information I require to configure. I just want to know what Information should I request the team inorder the configure FTPS so that it can be deployed properly.
I have checked with [SAP Help Link|http://help.sap.com/saphelp_nw04/helpdata/EN/e3/94007075cae04f930cc4c034e411e1/content.htm] and while configuring the communication channel found that I need Keystore and the X.509 Certificate and Private Key. which needs to be deployed on the J2EE server by using the Visual Administrator.
Is there anything else, I need to configure.
Any help would be appreciated in this regard.
Thanks & Regards,
Varun.K

The basic things are Certificate/Keys which you already know. Usually it is enough for running a sceanrio.
However, if you have additional requirements, like FTPS for "Connection Security" for encryption, then you may need additional details like commands. Rest all settings are same as FTP.

Prateek

Can't establish a sftp connection with the finder

I've searched for a fix or alternative on the internet and I haven't found one that works; The one that keeps coming up is to try: "ftps" as the protocol instead of "sftp" with the remaining information the same (it doesn't work, it gets the same error message afterwards).
The IP address and login information works (corroborated by the fact that I can log in from the terminal from the Mac Mini) so the only issue is with the finder capabilities for establishing the connection. I have looked for apple related documentation or How Tos but I haven't found anything useful.
I don't want to use any third party app or tweak because of the sensitive information that is going to be transfered, I would like to be using strictly the tools from the OS.
If you need any more information please let me know, any help is deeply appreciated.

I have the same issue although i kind of fixed it. I have two admin accounts and one of the account's safari did the same thing as yours, except, it was the startpage and everypage i tried to visit. I reseted safari, as in the erase all data safari in the toolbar, safari-Reset Safari... But safari still didn't work. I logged out and went to my other account and opened safari. Now it works fine on both accounts. This meant safari had to logout before actually working better. I have this a few times these days.

ABAP to FTP connect to non SAP UNIX system

Greetings~
I'm looking for a way (via function modules and/or BAPI) to transfer data in flat files from an SAP UNIX system to a non-SAP UNIX system using an ABAP program. I see FM's FTP_CONNECT and FTP_COMMAND however these seem to only work with UNIX systems running SAP as they require RFC_DESTINATION information. Anybody know which (if any) FM's can be used without the necessity of the target system running SAP/RFC?
Thanks!

Time to time its giving error in the FTP connection

Hi Gurus,
Im doing File to File Interface. Im using FTP for File transfer and the message protocol is 'File'. Im using the connection security as 'FTPS(FTP Using SSL/TLS) for control and data connection' and set the default command order.
I have uploaded the required certificate in the FTP server and the XI server also. I can view the certificate in the keystore of visual Administrator. Its working fine. But the problem is time to time its giveing this error "Error occurred while connecting to the FTP server "170.135.128.149:20021": iaik.security.ssl.SSLCertificateException: Peer certificate rejected by ChainVerifier"
Can anyone please help to resolve this issue. i need to fix it as soon as possible.
Regards,
Rama

Hi All,
I m facing one peculiar problem with FTP server. I have desinged one R3 to FTP interface. I m trying to connect to FTP with secure SSL connection. For that we uploaded the certificate in the FTP as well as in the Visual administartor in the XI box. I didnt create any SSL socket for this. Our basis team told like we dont need this SSL socket stuff because here we are using FTP as a client. So just they uploaded the certificate in the trusted CA of Visual administartor. Our certificate is obtained from verisign. So the CN name in the certificate is Verisign. I didnt find any thing in the certificate other then this. In our communication channel we gave the hostname instead of IP address. But here my problem is, When i send the file to FTP its giving error in the first attempt. After that the message retiried itslef, the file has been sent successfull in the retry process. Why it is always fails in the first attempt.
Can anyone please help me to resolve this. I need to be fix today itself.
Regards,
Rama

Establishing a socket connection between a .swf file and a socket-test program (TCP/IP builder - Windows), in AS3.

I have an issue with a college project I'm working on.
Using Actionscript 3, I made a simple .swf program, an animated, interactive smiley, that 'reacts' to number inputs in a input-box.
For the sake of the project, I now need to make the framework for establishing a socket connection with the smiley .swf, and another program.
This is where I encounter issues. I have very little knowledge of AS3 programming, so I'm not certain how to establish the connection - what's required code-wise for it, that is.
To test the connection, I'm attempting to use the "TCP/IP builder" program from windows, which lets me set up a server socket. I need to program the .swf file into a client - to recognize it, connect to it, then be able to receive data (so that the data can then be used to have the smiley 'react' to it - like how it does now with the input-box, only 'automatically' as it gets the data rather than by manual input).
My attempts at coding it are as follows, using a tutorial (linked HERE):
//SOCKET STUFF GOES HERE
    var socket:XMLSocket;
    stage.addEventListener(MouseEvent.CLICK, doConnect);
// This one connects to local, port 9001, and applies event listeners
    function doConnect(evt:MouseEvent):void
    stage.removeEventListener(MouseEvent.CLICK, doConnect);
    socket = new XMLSocket("127.0.0.1", 9001);
    socket.addEventListener(Event.CONNECT, onConnect);
    socket.addEventListener(IOErrorEvent.IO_ERROR, onError);
// This traces the connection (lets us see it happened, or failed)
    function onConnect(evt:Event):void
        trace("Connected");
        socket.removeEventListener(Event.CONNECT, onConnect);
        socket.removeEventListener(IOErrorEvent.IO_ERROR, onError);
        socket.addEventListener(DataEvent.DATA, onDataReceived);
        socket.addEventListener(Event.CLOSE, onSocketClose);
        stage.addEventListener(KeyboardEvent.KEY_UP, keyUp);
    function onError(evt:IOErrorEvent):void
        trace("Connect failed");
        socket.removeEventListener(Event.CONNECT, onConnect);
        socket.removeEventListener(IOErrorEvent.IO_ERROR, onError);
        stage.addEventListener(MouseEvent.CLICK, doConnect);
// Here, the flash tracks what keyboard button is pressed.
// If 'q' is pressed, the connection ends.
        function keyUp(evt:KeyboardEvent):void
        if (evt.keyCode == 81) // the key code for q is 81
            socket.send("exit");
        else
            socket.send(evt.keyCode);
// This one should handle the data we get from the server.
        function onDataReceived(evt:DataEvent):void
        try {
            trace("From Server:", evt.data );
        catch (e:Error) {
            trace('error');
    function onSocketClose(evt:Event):void
        trace("Connection Closed");
        stage.removeEventListener(KeyboardEvent.KEY_UP, keyUp);
        socket.removeEventListener(Event.CLOSE, onSocketClose);
        socket.removeEventListener(DataEvent.DATA, onDataReceived);
Trying to connect to the socket gives me either no result (other than a 'connection failed' message when I click the .swf), or the following error:
Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: file:///C|/Users/Marko/Desktop/Završni/Flash%20documents/Smiley%5FTCP%5FIP%5Fv4.swf cannot load data from 127.0.0.1:9001.
    at Smiley_TCP_IP_v4_fla::MainTimeline/doConnect()[Smiley_TCP_IP_v4_fla.MainTimeline::frame1:12]

Tried adding that particular integer code, ended up with either errors ("use of unspecified variable" and "implicit coercion") , or no effect whatsoever (despite tracing it).
Noticed as well that the earlier socket code had the following for byte reading:
"sock.bytesAvailable > 0" (reads any positive number)
...rather than your new:
"sock.bytesAvailable != 0" (reads any negative/positive number)
Any difference as far as stability/avoiding bugs goes?
So then, I tried something different: Have the program turn the "msg" string variable, into a "sentnumber" number variable. This seemed to work nicely, tracing a NaN for text (expected), or tracing the number of an actual number.
I also did a few alterations to the input box - it now no longer needs the 'enter' key to do the calculation, it updates the animation after any key release.
With all this considered and the requirements of the project, I now have a few goals I want to achieve for the client, in the following order of priority:
1) Have the "sentnumber" number variable be recognized by the inputbox layer, so that it puts it into the input box. So in effect, it goes: Connect -> Send data that is number (NaN's ignored) -> number put into input box -> key press on client makes animation react. I optionally might need a way to limit the number of digits that the animation reacts to (right now it uses 1-3 digit numbers, so if I get sent a huge number, it might cause issues).
- If the NaN can't be ignored (breaks the math/calculus code or some other crash), I need some way of 'restricting' the data it reads to not include NaN's that might be sent.
- Or for simplicity, should I just detect the traced "NaN" output, reacting by setting the number variable to be "0" in such cases?
2) After achieving 1), I'll need to have the process be automatic - not requiring a keyboard presses from the client, but happening instantly once the data is sent during a working connection.
- Can this be done by copying the huge amounts of math/calculus code from the inputbox layer, into the socket layer, right under where I create the "sentnumber" variable, and modifying it delicately?
3) The connection still has some usability and user issues - since the connection happens only once, on frame 1, it only connects if I already have a listening server when I run the client, and client can't re-connect if the server socket doesn't restart itself.
I believe to do this, I need to make the connection happen on demand, rather than once at the start.
For the project's requirement, I also need to allow client users to define the IP / port it's going to connect to (since the only alternative so far is editing the client in flash pro).
In other words, I need to make a "Connect" button and two textboxes (for IP and port, respectively), which do the following:
- On pressing "Connect", the button sets whatever is in the text boxes as the address of the IP and port the socket will connect to, then connects to that address without issues (or with a error message if it can't due to wrong IP/port).
- The connection needs to work for non-local addresses. Not sure if it can yet.
- On re-pressing connect, the previous socket is closed, then creates a new socket (with new IP/port, if that was altered)
It seems like making the button should be as simple as putting the existing socket code under the function of a button, but it also seems like it's going to cause issues similar to the 'looping frames' error.
4) Optional addition: Have a scrolling textbox like the AIR server has, to track what the connection is doing on-the-fly.
The end result would be a client that allows user to input IP/Port, connects on button press (optionally tracking/display what the socket is doing via scrollbox), automatically alters the smiley based on what numbers are sent whilst the connection lasts, and on subsequent button presses, makes a new connection after closing off the previous one.
Dropbox link to new client version:
https://www.dropbox.com/s/ybaa8zi4i6d7u6a/Smiley_TCP_IP_v7.fla?dl=0
So, starting from 1), can I, and how can I, get the number variable recognized by "inputbox" layer's code? It keeps giving me 'unrecognized variable' errors.

Multiple FTP connections

I'm using Labview 8.2 with Internet toolkit. I'd like to connect to multiple FTP sites, and download files from all sites simultaneously. I would simply use parallel cycles to do that, but it's not possible because the toolkit's FTP VIs are not reentrant, so for example i can't run two "FTP Get File.vi" at the same time. Do you think i could modify those VIs, making them reentrant, or there is some technical limit that allows only one FTP download at a time?

Thanks Paolo, i tried to set as reentrant all the call chain to TCP Read Stream.vi; i also tried to set as reentrant all the FTP VIs, except FTP Registry.vi which looks like a functional global. It seems to work, i can download from two FTP sites simultaneously, but the gain in performance is very low. Parallel downloading (two groups of files from two sites) takes only 10% less time than serial downloading (one site at a time). Where's the bottleneck? Maybe total network speed?

Poor performance in establishing an SSL connection

Hi,
i have a Servlet (loaded on Tomcat 4.1) that establishes a SSL Connection to a remote server. The issue is, is that the connection phase takes over 4 seconds to complete!
heres the function where the problem shows
public SSLSocket getSocket()
throws NoSuchAlgorithmException, KeyStoreException, FileNotFoundException,
IOException, KeyManagementException, CertificateException,
UnrecoverableKeyException
* Set up a key manager for client authentication if asked by the server.
SSLSocketFactory factory = null;
SSLContext ctx;
KeyManagerFactory kmf;
KeyStore ks;
// Set the SSL Context to TLS (required for Client certs).
ctx = SSLContext.getInstance("TLS");
kmf = KeyManagerFactory.getInstance("SunX509");
ks = KeyStore.getInstance(ksType);
// Load in the KeyStore.
ks.load(new FileInputStream(ksLoc), ksPassphrase);
kmf.init(ks, ksPassphrase);
// Generate some random data.
SecureRandom sr = new SecureRandom();
sr.nextInt();
// Initialise the SSL with the random data.
ctx.init(kmf.getKeyManagers(), null, sr);
factory = ctx.getSocketFactory();
* Open the Socket to the SSL server. from this point we can treat
* it like and nomal Socket
SSLSocket socket = (SSLSocket)factory.createSocket(servHost, servPort);
// Force the handshake
socket.startHandshake();
// Return the now open SSLSocket to the caller.
return socket;
the problematic line is:
SSLSocket socket = (SSLSocket)factory.createSocket(servHost, servPort);
it takes about 4.5 - 5.0 seconds to return. The remote server is based on the same LAN as this Servlet and so network lag should not be an issue (im accessing via 10.xx ip too)
Can anyone help me in determining why this takes so long?
Thanks !
Darren.

First, try by removing the line which says:
socket.startHandshake();because the handshake will be initiated by the socket upon creation.
If you are using JDK v1.4.1 I've seen some SSL performance issues when stablishing the connection, so I returned to my old JDK 1.3.1.
Also be sure to create the factory in the servlet init() method because it has no sense to recreate the factory in every request as long as it uses the same KeyManager.
