Hi, first thank you for this wonderful product!
Now to my problem:
I run Winscp as service on my windows server to keep the big unix server updated with incoming files (the files are created on the windows box). This is the command used:
Code:
winscp.exe PDFUpload /console /script="PDFUpload.scp" /log="WinSCP.log"
This the PDFUpload.scp file:
Code:
option echo off
option batch on
option confirm off
option synchdelete on
keepuptodate "C:\PDFtoUpload" /upload
close
exit
Now, this should run all the time, however if a short network problem prevents connection to the server, the synchronisation halts with the following message in the logfile:.
Code:
 2008-04-08 09:16:40.591 Waiting for data timed out, asking user what to do.
. 2008-04-08 09:16:40.591 Asking user:
. 2008-04-08 09:16:40.591 Host has not answered for 15 seconds.
. 2008-04-08 09:16:40.591
. 2008-04-08 09:16:40.591 Wait for another 15 seconds? ()
. 2008-04-08 09:16:40.591 Attempt to close connection due to fatal exception:
* 2008-04-08 09:16:40.591 Terminated by user.
. 2008-04-08 09:16:40.591 Closing connection.
I know, the 'option batch on' means that "all prompts are automatically replied negatively". Is there a way to force positive answers to these kind of questions? I tried the options continue as well, but no success. Please help me! So far the only solution is to restart WinSCP.

What does it do with "option batch continue"?

All I get is this in the log:
Code:
. 2008-04-09 14:07:09.502 Collecting synchronization list for local directory 'C:\temp\aaa\' and remote directory '/temp/bbb/', mode = 0, params = 187
. 2008-04-09 14:07:09.502 Listing directory "/temp/bbb".
> 2008-04-09 14:07:09.502 Type: SSH_FXP_OPENDIR, Size: 18, Number: 3083
. 2008-04-09 14:07:09.502 Network error: Software caused connection abort
I wish WinSCP would try to reconnect to the server when a watched dir is changed.
I tested with a local server (freeSSHd) by simply quitting the server, deleting a file in the watched directory, starting the server again, and deleting another file.

Is there a way to perform a "Synchronize on start" when starting Keepuptodate in script mode? The problem is this:
WinSCP detects a change in a local subdirectory and attempts to upload the files. But the server is not responding at the moment, so WinSCP aborts. After a while someone notices, that there are files missing on the server, so I restart WinSCP in script mode, so it starts to listen again. But those files not uploaded will not be updated on the server even if another directory is changed. If I am lucky, the same directory will be changed after a while, and then the older files are uploaded as well. So now I cannot initiate an automatic restart of WinSCP, I have to synchronise manually first before the restart.

PS: sorry, just found out that simply issuing a 'synchronize remote' command before the keepuptodate command will just do the trick...
So, I'm planning now to start WinSCP from the scheduler every 5 minutes and do a full synch. Not as elegant as the keepuptodate method, but hey, at least it works!

Oops, that is what I did just after your post. It wasnt obvious, sorry. But, the log i posted was with the continue option:
Code:
. 2008-04-09 14:07:09.502 Collecting synchronization list for local directory 'C:\temp\aaa\' and remote directory '/temp/bbb/', mode = 0, params = 187
. 2008-04-09 14:07:09.502 Listing directory "/temp/bbb".

Thank you, before posting I searched only the forum, not the tracker. My fault, sorry. Thanks for adding this thread as comment.

I'm having this same issue. My script is "sometimes" terminated when network connection is temporarily lost.
Here's my script file:

option batch continue
option confirm off
option synchdelete off
option transfer binary
open ShellFBO
synchronize remote E:\dir1 /dir1
keepuptodate E:\dir1 /dir1

I say "sometimes" above because I have watched the script work through network connection problems in the past. Here's a couple excerpts from my log:

When the script worked through a network connection problem:
. 2008-04-15 02:58:57.564 Waiting for data timed out, asking user what to do.

Here's an excerpt when the script terminated:
. 2008-04-15 09:10:11.013 Waiting for data timed out, asking user what to do.
. 2008-04-15 09:10:11.013 Asking user:

. 2008-04-15 09:10:11.013 Attempt to close connection due to fatal exception:
* 2008-04-15 09:10:11.013 Terminated by user.
. 2008-04-15 09:10:11.013 Closing connection.

after the above error, the script was terminated, and the computer was sitting at the winscp> prompt.

anyone have any ideas what the problem might be? i have tried playing around with scripting options, and have found the "batch continue" option to work better than the "batch on", and thought I had the problem licked, but apparently not.

any advice is appreciated.

Thanks!

Yes this is exactly the problem I had. So far the only solution was for me to start WinSCP from the Task Scheduler every 5 minutes and do a full synch like in your script. It is basically the same script without the keepupdate command.

In the first log the connection was automatically reestablished. WinSCP supports that only while transferring a file. In other cases it is not able to reconnect automatically. So in the first case it is possible that transfer was ongoing, while in the other case it were not.
