In case anyone is interested, the cure in my case was to reboot. The problem went away after I restarted.

You cannot yet. It will be possible in the next release (see tracker). However you can save stored session with passive mode enabled in GUI and use that session from script.

I thought about that and even tried it, but I am not sure I know how to change to passive mode in a script.

Is the command?
option passive on

There is also a command line flag, but I could not find how to use it. Should I use:

winscp.exe /script=xxx /passive=on

or should it be
option passive yes
/passive=yes

Also, in looking at my own post I notice I have
confirm off
in the script instead of
option confirm off

I will check to see if that is the problem.

Maybe you are using passive mode from GUI?

I am using WinSCP 4.0.7 (Build 370) to transfer files via FTP in batch mode. If I connect to the server with the GUI it works fine but the batch script fails. It worked fine until about a week ago, then it stopped working. I cannot figure out what changed.

A typical batch script is:
# 20080302-2024-a1-ftp.tmp
option batch on
confirm off
open ftp://xxx:yyy@200.12.166.180
option transfer binary
cd BIN_level1b/2008/0803
lcd X:\modis\20080302-2024-a1
get 20080302.2024.a1.modis_cal.png
get 20080302.2024.a1.modis_cal_250_b1.tar.bz2
get 20080302.2024.a1.modis_cal_250_b2.tar.bz2
get 20080302.2024.a1.modis_cal_500_b7.tar.bz2
close


It is called with
WinSCP.exe /script=%ftpTempName% /log=%fecha%-%hhmm%-%sat%-winscp.log

The log file contains:

Any ideas on where to look for the problem?
