    Verify integrity of ftp file transfers

    Verify integrity of ftp file transfers

    With FTP you can use a couple of ‘Non-standard‘ Commands to verify the integrity of a file transfer (download & upload):

    • XCRC
    • XMD5
    • XSHA1, XSHA256, XSHA512

    In version v2022.6.12.0 of Limagito File Mover we added support for these Commands to:

    • Built-In FTP Server
    • FTP as Source
    • FTP as Destination

    Not all FTP servers support this ‘Non-Standard’ command. You can check this using the ‘Support’ tab in your FTP Destination setup (v2022.6.12.0). Click ‘Connect’ and check if File Verification is supported by the FTP server. In this screenshot we are connected to the Limagito FTP Server.

    If your FTP server supports File Verification then you can enable this in the FTP Source or Destination setup (Verify Tab > Verify File after Copy/Move).  If your FTP Server does not support File Verification and you need this then maybe you can use: link.

    SFTP Connection errors 10054 (0x2746)

    Q: SFTP Connection errors 10054 (0x2746). Is there something we can look at in regards to this error?  What causes it and if we can resolve? We’ve encountered a situation twice now where a vast amount of rules appear to stop processing to 1 particular server.  The rules in web remote all turn green and stay green as if they are currently being triggered, but there is no output on the runtime log and no transfers take place. To resolve the issue we’ve restarted the Limagito server, and rule processing occurs normally again. Are we able to provide you with some logs that might help shed light on what’s occurred?

    We have 173 rules, and of the failures they seem to be with this 1 SFTP server, destination and source rules. Is there a preference in which one we use? We scan the rules every 70 seconds.

    • With our SFTP Source Code Vendor 1 (SB) the error message looks like:

    6/3/2022 9:12:57 AM SFTP Connected Error

    6/3/2022 9:12:57 AM Connect attempt 1 Exception: Connection lost due to error 10054

    • With our SFTP Source Code Vendor 2 (CK) the error message looks like:

    SFTP Connection Errors

    A: With 70 seconds scan time we would certainly enable the ‘Stay connected’ option (Common Tab of SFTP setup). We guess this SFTP server is no longer accepting new connections (after x time). Please also check the ‘Hint’ in the feedback when using our SFTP Source Code Vendor 2 (CK). If you trigger the rules often then some SFTP servers will find this (connects/disconnects) suspicious and will no longer allow new connections for a certain time.

    • SFTP Setup (Source or Destination), enable ‘Stay Connected’.

    SFTP Stay Connected option

    #SFTP #Filetransfer #Filemanagement

    Verify FTP download using existing hash file at source

    Q: I am downloading a file, plus the sha256.hash that was created at the file source via FTP. How can I verify FTP download with an already existing hash file? If the feature exists, I don’t seem to be able to find it. An example file name for my application is 12345.dmp – and the hash file is 12345.dmp.hash

    A: In our latest version v2022.6.6.0 we added an option to achieve your request.

    • Please open your FTP as Source Setup:

    Limagito File Mover FTP as Source

    • Select the Verify Tab:
      • Enable ‘Use Checksum file at source to verify download’ option
      • Select the ‘Algorithm’ you used to create the hash file on the FTP server
      • Select the ‘Encoding’ you used to create the hash file on the FTP server
      • Set Checksum Filename. Default is %SFN (= Source File Name) + .hash
        • We will look for that file at the FTP source to verify the download
      • Select if you want to keep the the checksum file download (move to Destination)

    • File Filter Setup. In our example we are downloading and checking .pdf files so we added the *.pdf extension to the Filename Include Filter option. Please do not include the hash file extension, this is all handled by the ‘Use Checksum file at source to verify download’ option itself.
