Able to copy from IDE, but "Can't open data connection" from the command line.

Hi,

We're using WinSCP 5.11.3, build 7995

We have an FTP site e.g.
ourftpsite.ouragency.com, port 21
and we can send files to the /home/ folder via the ide.

But we're not able to use a batch file to send it.

Our batch file, OUR_Weekly.CMD, is 
@ECHO OFF
 
CD "C:\scripts"
 
winscp.com /script=OUR_Weekly.txt /log="C:\LOGS\OUR_WEEKLY.LOG" /loglevel=0*
 
exit
OUR_Weekly.txt is 
open ftp://OurUser:OurPassword@ourftpsite.ouragency.com/
 
put D:\inetpub\FTPROOT\apps\ourweekly\ourweekly.zip /home/
 
exit
, and the errors are

Please attach complete session log files both from the successful upload from IDE and the failed upload from the script. Consider using the latest version of WinSCP for both.

Hi Martin,

Thanks, but I'm nervous about trying to mask server name and credentials in the log file, and afraid I might miss something.

Everything's fine, now. I found out about your feature to auto-generate the command-line script from Transfer Settings. There were a couple of glitches, but they were easy to figure out.

T & R,
