FTP Server in Labview

I would like to embed an FTP server into a Labview application. Is there a way to do this?

Both windows and linux have FTP servers that are capable of being installed from their respective manufacturers, can't speak to a MAC. Although the LINUX one is more powerful. So that should not be an issue.
I am only thinking about how much time you spend writing an ftp server, especially if you need to support FTP and SFTP, plus all of the various functions that are part of the protocol stack... then debugging. Not going to be fun and not going to be done in a week or two.
I might pursue the licensing issues before I took to writing my own. Although I fully understand the keep it in the house thing.

I'dd like to use LabView to attach to a CNC FTP server and download and unplad information to it. I'm using 6.i

I am trying to attach to a FTP server on a CNC machine. I have been looking for code in 6.i that I can use with out buying the internet tool kit.

Nick,
I'll bet you're having trouble because you're trying to retrieve unformatted text (i.e. not a .wav or .tdt or some other common format). In this case, I think you want to use the [text] argument on the end of the URL, as outlined in one of the KB docs.
I've attached an example that I can run here without error; it retrieves one binary (zipfile) and one textfile from the ni.com FTP site. Try it and examine what I did.
Best of luck,

How do I restrict access to the RT Series PXI Controller via its FTP server?

The RT Series PXI Controllers run an FTP server, so I can view files on the controller over the Internet wtih a Web browser. I can also download and upload files with a Web browser. How can I instruct the FTP server to give access only to specified, trustworthy FTP clients?

It is possible to "Lock" the controller from the Measurement and Automation Explorer program. The password you set when locking the controller (which prevents others from making configuration changes to the controller while running) is the same password that controls access to the FTP server. When the controller is unlocked, anyone who can access the PXI controller's IP can read, write, and delete files on the FTP server. When locked, anyone can read data from the FTP server, but only when logged in with the lock password will you have access to write or delete data.
For more information on locking your controller, see the user manual, MAX online help, or the following link.
NI Developer Zone: Controlling Access to LabVIEW Real-Time PXI Targets

FTP server performance

I find the performance of the FTP server on the PXI RT controller very poor. I only reach a performance of about 1 kbyte/s, making file exchange very cumbersome. On the other side, tcp performance (for communication set up in programs) as well as communication performance through LabView RT is fine, so the network connection cannot be the problem. The FTP performance is poor independent of the FTP client in use on the Windows PC side, even for FTP through MAX.
Any idea what I might do wrong or is this bad performance "normal"?

By chance, I found some comments about problems with crossover cables and network interface chips. My problem seems to be caused by this, using a hub in between performance is much better and ok.

How can i do scheduled automatic backups to an ftp server in ios xr?

Hello guys! As the title says im looking forward to automatically back up my running config on a cisco CRS-1 to an FTP server. I was only able to find this config example:
Configuration commit auto-save filename ftp://A.B.C.D/myconfig.txt
This allows me to save my config to an ftp server everytime i use commit on the device. Now i want to know if there's a way to automatically save my configs everyday at 00:00 and also include the date and time in the name of the file so i don't overwrite the existing files in the ftp server.
I dont want to use any tool i just wanna know if what im asking is possible via CLI commands. I would greatly appreciate your help with this subject.
Regards,
David

Not sure if this script will work on a CRS, but try this:
archive
log config
logging enable
hidekeys
path tftp:///$h-
write-memory
time-period 10080
Explaination:
There are two ways to save your config to your remote station:
1. When someone saves the config; and
2. At an alloted time period, expressed in 10080 (weekly for me).

Java ftp server which can use LDAP, how to integrate with WLS' implementation of LDAP?

Howdy.
I'm setting up a java ftp server
(http://www.mycgiserver.com/~ranab/ftp/index.html) which is capable of using
LDAP for it's user security. I would like to integrate this ftp server with
wls' implementation of LDAP so I only have to admin one user list.
Does wls put it's user list in the LDAP or in it's own proprietary setup? I
tried playing around with it, but the users don't seem to appear in the JNDI
tree. Is this where the LDAP stuff is located? I thought it was in there?
If it's in it's own setup, is there a way to propagate the users to LDAP?
If these look like newbie Q&A, I guess they kind of are, I'm new to LDAP.
Thanks for any input you might have.

Peter,
If you are talking about using the embedded LDAP server in WLS 7.0 for this purpose
I think you are going done the wrong path.
Look at the following URL on how to use an external LDAP server for your custom
application

Output to an ftp server via Destinations or Applescript

In Compressor, you can set the Destination of a compression batch to be a remote server, such as an ftp server.
When you start a batch, if the destination is not available or reachable then the documentation (p.230) says: "When there is a problem with your destination, a yellow warning triangle appears. You must resolve this problem before you can successfully transcode."
Although I have not tried it, it implies that if your remote ftp server is not accessible when you drop a file on a created droplet with the Destination set to an ftp server, it won't be able to begin encoding until the destination is available: "As soon as you resolve the problem, the warning triangle disappears and you can continue to transcode." (p.230)
For a lot of people, this is OK.
Some people need to compress and then tranfer the output to a distant location, and they may not have continuous, reliable access to the remote location. They may need to make a temporary connection via modem dial-up, satellite phone or third-world Internet connections. Think news reporters in remote locations.
So, for those people, the option of Applescript should allow them to have their output files saved to a local destination, and then staged up to the ftp server using the built-in commands. But, the problem is that a small file is created at the Destination when the compression is started, and Compressor is not Applescript aware (apart from being able to call an Applescript). This means that any Applescript called as a post processing activity knows nothing about the files Compressor just processed and outputted. It has to glean information about them from the Destination folder where the output files are placed, and then sort out the completed output files from the ones that have just been started, then ftp the completed files up to an ftp server and delete sent files from the Destination folder.
What I would like to see is either
1) a Staged Destination where files are created on the first Destination then staged to a secondary Destination, with an option of keeping these files on the first destination, and/or
2) Applescript support in Compressor which will allow information about the files that have just been compressed to be passed to another Applescript aware application or script.
I would be happy even with some sample Applescript to do the transfer or files from Destination to an ftp server that avoids copying files that haven't been fully processed.
Has anyone else run into these issues?
Bill Lee

Oh, trust me, I do know about Apple and the fact this discussion site is not an official contact point for Apple. I'll be escalating this Request for Enhancement through my contacts at Apple.
There is a reason I have not posted before in this forum (and relates to the above).
There seems to be few people who are using the Applescript post-processing feature, and I was trying to gauge any support for enhancements in this area (and maybe stir up some villagers with pitchforks and burning torches).
Apple will listen to normal users input, but it needs to have a business case that justifies any resources devoted to this. The more people affected, and the greater the impact on your business, and the size/importance of your business has an effect on whether you will get what you want, and when.
Sorry if I was not clear on what I wanted: information as whether this was important for other (non-Apple) people, and whether people had scripts that solved the problem of staging output files to an ftp server that was not consistently connected during the compression process.
Thanks for your reply,
Bill Lee

No Data in PDF file in FTP server

Hi All,
I am trying to place a PDF file in FTP server.
Used
CONVERT_OTFSPOOLJOB_2_PDF to convert spool to PDF
SCMS_TEXT_TO_XSTRING
FTP_R3_TO_SERVER to transfer data to FTP.
I am able to see PDF file in FTP and no of pages matches with that of R/3 but there is no data in PDF file.

To get pdf file , you need to set the itcpo-tdgetotf = 'X' and need to pass in the exporting parameter (options in open_form function module ).Then in close_form function module take all the data of otfdata table into an internal table . Then use SX_OBJECT_CONVERT_OTF_PDF function module to convert it to pdf.
I will show with an example.
tables itcpo.
DATA: ch_otf TYPE STANDARD TABLE OF itcoo.
DATA: w_otf TYPE itcoo.
DATA: w_pdf TYPE solisti1. "For PDF

        wa_content_bin TYPE solix,
        i_objhead TYPE soli_tab.
itcpo-tdnoprint = 'X'.
itcpo-tdpreview = 'X'.
itcpo-tdgetotf = 'X'.
These three parameters need to be passed along with other required parameters
CALL FUNCTION 'OPEN_FORM'
       EXPORTING form = xformular
                 language = ekko-spras
                 OPTIONS = itcpo

                 archive_params = arc_params
                 device = xdevice
                 dialog = xdialog
                 mail_sender        = sender

    CONCATENATE w_otf-tdprintcom w_otf-tdprintpar

    APPEND w_pdf TO i_content_txt.
ENDLOOP.
converting otf file to pdf file
CALL FUNCTION 'SX_OBJECT_CONVERT_OTF_PDF'
    EXPORTING
      format_src      = temp1        "'OTF'
      format_dst      = temp2        "'PDF'

    EXCEPTIONS
      err_conv_failed = 1
      OTHERS          = 2.
Then open dataset and transfer to ftp of the content of table content_bin(i_content_bin) as shown in above example.
I think this will be helpful for you

Hi, if you really retrieve an excel file, you can not see the data in ABAP. You may see them in Excel. For this you may use
CALL METHOD document->open_document_from_table
of the interface i_oi_document_proxy for OLE objects. You can access the data with reference to the interface i_oi_spreadsheet.
Please check [Desktop Office Integration (BC-CI)|http://help.sap.com/printdocu/core/Print46c/en/data/pdf/BCCIOFFI/BCCIOFFI.pdf] for details.
But, who knows, perhaps you want "And Now For Something Completely Different".

Hi Rakhi,
Use the below code to check if you have received the proper data.
call function 'FTP_SERVER_TO_R3' "Get data as character instead of BLOB
    exporting
      handle         = hdl
      fname          = docid
      character_mode = 'X'
    tables
      text           = chardata.
If the data is incorrect, it is possible that you are in the wrong directory.
Use
call function 'FTP_COMMAND'
    exporting
      handle        = hdl
      command       = 'cd mydir\mysubdir' "cd <space> your path
    tables
      data          = result
    exceptions
      tcpip_error   = 1
      command_error = 2
      data_error    = 3.
