detailed FTP command/parameters ?

[ricorico94]

Hi,
Is there a way to view the actual commands sent by BC3 to FTP server ?
I have a weird behavior: filezilla can still connect to my remote FTP server, but BC3 is apparently rejected (even with Filezilla disconnected).
BC3 error is (translated into English, sorry for poor translation) : no connection could be established due to target computer having formally rejected it.
Weird, since I did not change login/pwd nor parameters (at least I don't see any change) and Filezilla connections still work well.

The log at the bottom of the directory compare (available as View->Show Log in the menu) shows all of the commands that BC sends. That particular one means that it wasn't able to connect at all though, so it was never able to send any commands. The most common reason for that is a firewall issue or trying to connect to the wrong remote port (21 for FTP, 22 for SFTP, 990 for FTP over implicit SSL).

BC3 should show details of the FTP connection in the log pane at the bottom of the Folder Compare or Folder Sync window.

If you are having trouble connecting, please send a copy of the log showing a problem connection to [email protected]. Also, please include a copy of your Beyond Compare 3 settings.

To save the log to a file, click the Save button on the left side of the green log pane. To save your BC3 settings to a file, select "Help > Support" from the menu and click the Export button.

Hi,
In the log file, I can only read:

07/06/2010 18:06:16 Nom d'utilisateur : XXX\XXXX (I replaced actual login by X)
07/06/2010 18:06:18 Aucune connexion n’a pu être établie car l’ordinateur cible l’a expressément refusée
07/06/2010 18:06:18 Charger la comparaison : F:\BackupDD\Fichiers Download <->

note that I have checked all settings in Log parameters. This does not say much about why it can not connect.. I can not see any FTP command (AUTH TLS, USER XXX,..).
This morning it was connecting properly, and on a PC with no firewall (for easiness of testing !). Moreover, Filezilla is connecting from same PC and can connect as mentionned.

I forgot to mention that I use FTPS, in case it matters..

Try changing the port to 990. In the path edit it would look like:

ftps://xxx@xxx:990/

[Chris]

It might be trying to connect on the wrong port. If you haven't specified a port, BC3 is probably connecting to port 21. It's possible Filezilla is connecting on port 990.

In BC3, click on the browse button to connect to your FTPS server. Go to the "FTP Site" tab. Select "FTPS" as the protocol, then enter 990 as the port to connect on.

Thanks for help. Still unsuccessful, even with port 990.. and I checked Filezilla, which is connecting to port 21.

Regarding log file of BC3, I get only few info, depsite all checkmarks are selected (details, trace FTP,..):
07/06/2010 22:34:05 Nom d'utilisateur : XXXXX\YYYY
07/06/2010 22:34:05 Charger la comparaison : <->
07/06/2010 22:35:00 Aucune connexion n’a pu être établie car l’ordinateur cible l’a expressément refusée
07/06/2010 22:35:05 Aucune connexion n’a pu être établie car l’ordinateur cible l’a expressément refusée
07/06/2010 22:35:05 Charger la comparaison : <->
07/06/2010 22:45:26 Aucune connexion n’a pu être établie car l’ordinateur cible l’a expressément refusée

At same time, Filezilla gives me:

Hello,

Do you have a software firewall you are currently running? If so, try disabling it temporarily to see if you can connect.

Also, in BC3, go to the Tools menu -> FTP Profiles, specific profile, Connections tab. Turn the number of connections down to 1, and then close all BC3 windows and restart BC3.
