Re: Need Help with FTP API - Getting error with SIZE

[Scott Klement <sk@xxxxxxxxxxxxxxxx>]

   Hello Dan,
   The 'SIZE' command is not available in all FTP implementations, it's an
   extension to the protocol.  The only way FTPAPI can tell whether the
   server supports (or doesn't support) SIZE is by sending the command,
   and checking the response to see if it's supported.  And that's what it
   does.
   It sends SIZE, and if it's unsupported it ignores the error and
   continues.   I can't see why you'd get a timeout error here...
   Please generate a session log.  You do that by adding FTP_log(*on) to
   your progam, just before you connect to the server.  Then look at the
   output of the log (which is in your job log) and I think you'll see
   that the timeout is occuring on RETR rather than SIZE.   At least, that
   would be my guess...
   If it's not, and you're truly getting the error on the SIZE command
   then please tell me how to reproduce the problem, as I've never seen
   that happen, and can't do anything about fixing it if I can't reproduce
   it.

   I'm trying to do a Get Command, the file that I need is on a Windows

   Now that I'm trying to GET the PDF file that I placed on the server it
   fails.
   I've tracked the issue down to the point that a send is done requesting
   the SIZE of the file.
    *Change to Binary Mode
   c                   callp     ftp_binaryMode(sess: *on)
    *Change Name Format to 1
   c                   callp     ftp_NamFmt(sess: 1)
    * Get the Requested file
   c                   if        ftp_get(sess: SendFrom:SendTo)<0

   SendFrom= /00000010000007009747180009010910909.pdf
   SendTo =   /pdf/00000010000007009747180009010910909.pdf

   Looks like all goes well until the SIZE is requested

    * get total number of bytes to receive
   c                   eval      wkTotBytes = FTP_size(peSocket :
   c                                                   peRemote )


   * send size command:
   c                   if        SendLine(wkSocket: 'SIZE ' + peFile)<0
   c                   return    -1
   c                   endif

    * 213 <byte size>
   c                   eval      wwReply = Reply(peSession: wwMsg)

   ***** Connection Times out while waiting on response ****

   ***** What was sent in SendLine ***** = SIZE
   /00000010000007009747180009010910909.pdf


   NOTES:
   1) I'm currently using this same API to do a PUT from the AS400 to this
   Windows FTP server w/o any issues.
   2) I used FTP on the AS400 and was able to transfer this file from the
   Windows FTP server to the IFS on the AS400.
   3) I issue the BIN and NA 1 commands before I request the GET. They
   apear to work.

   Thanks in advance for any help you can supply.
   Dan
