FTP Server drops connection on large files (5 posts)

  Hi,

  I frequently have to transfer large PDF files to my printer and for large files the connection always drops in the middle.
  I am running OS X 10.4.10 with Fetch 5.2.
  The exact error message:

  Fetch could not put "XYZ.pdf" because the FTP server dropped the connection.
  Try again or contac tthe server administrator to verify that the server is running.
  Server responded: "Opening BINARY mode data connection. Ready to write file . ("/Various/XYZ.pdf") S T O R"

  Accroding to the transcript this seems to happen every time after exactly 12:10 minutes. I have tried Passive mode on/off and "Keeping Connections Alive" on/off.
  Any hint as to whether this is my problem or theirs would be much appreciated!

  Here is the transcript: ( The PDF has been renamed for subsequent attempts.)

  Hi,

  We're sorry you're having troubles with Fetch. We have a few questions for you to help us identify the problem.

  (1) You said that you're using "Fetch 5.2." If you haven't updated your copy to Fetch 5.2.1 already, could you please do that and see if it helps?

  (2) Is your Mac connected directly to your cable or DSL modem, or are you connecting the Internet using wireless or a router?

  (3) Have you double-checked with folks who run the server to make sure that there is space to store such a large file? You'd hope a printer would have plenty of space on their server, but the fact that the transfers always fail at around the same time and place could suggest an out-of-space problem.

  Let us know, and try to figure out the problem based on the answers.

  Thanks,

  Scott McGuire

  Hello Scott,

  thank you for your fast reply. It has been suggested to me by a colleague to try the ftp programm Cyberduck (oh no, the competition!!), they have an option: "Send 'no operation' command to keep connection alive"
  This has worked! (in Passive ftp mode). That should eliminate (3).

  As for (2) I am connected via a DSL Router (not wireless).

  Re: (1) I will have to transfer another large file tomorrow and will try Fetch 5.2.1 for that. I will let you know how it goes...

  I hope we can find a solution, since I am very happy with Fetch in all other respects ;-)

  Many thanks,
  Philou

  Hello,

  unfortunately an update to 5.2.1 did not solve the problem. Here's the last bit of the transcript:

  TYPE I
  200 Command ok : Binary type selected.
  PORT 192,168,1,4,238,193
  200 PORT command successful. 85.176.202.68:4464.
  STOR ABC.pdf
  150 Opening BINARY mode data connection. Ready to write file . ("/Varios/ABC.pdf") S T O R
  Unsuccessful transfer of ABC.pdf (74,842,112/199,747,623 bytes, 102,383 bytes/sec, 12:11 elapsed) stopped at 07.09.2007 13:29:34 (error: 2,-30014)
  ftp_store: 2,-30014 (state == RPUT_SENDING)

  I assume that the ftp server does not recognize the way Fetch keeps the connection alive.

  Hi,

  Thanks for the additional information.

  The "keep connection alive" option in Fetch sends "no operation" messages as well, so it probably does pretty much the same thing as Cyberduck's option.

  From the transcripts, it looks like you are using Fetch in non-passive mode, so you might try making sure that you have the "Use passive mode transfers on" and the "Keep connections active" options on at the same time in Fetch - mimicking the setup in Cyberduck - and seeing if that works the next time you transfer a file.

  Please let us know.

  I'd like to see a transcript from Cyberduck (in order to see what it might be doing differently), but I couldn't figure out how to show a transcript window in it...

  Thanks,

  Scott McGuire
