RSync?

I am using Delphi and I am in the process of trying to use 'rsync' via 'ssh' in order to "download" a few files from a Linux server onto a Windows client.

Via the use of a 'TScFileStorage' and a 'TScSSHClient' components, I am able to establish a connection from my Windows Desktop to my Linux server.

In order to run 'rsync' via 'ssh,' I am using a 'TScSSHShell' component.

Here is my code:

iCommand := 'rsync -vrtzn --delete -e ssh @:/data/ /cygdrive/c/data/';
try
ScSSHClient.Connected := True;
try
ScSSHShell.Connected := True;
iResponse := ScSSHShell.ExecuteCommand(iCommand);
ShowMessage(iResponse);
ScSSHShell.Connected := False;
except
on E: Exception do ShowMessage(E.Message);
end;
ScSSHClient.Connected := False;
except
on E: Exception do ShowMessage(E.Message);
end;

If I set the 'NonBlocking' property of my 'TScSSHShell' component to 'False,' I get a blank response.

If I set the 'NonBlocking' property of my 'TScSSHShell' component to 'True,' I do not get response. The program seems to hang.

Does anybody know what I might be doing wrong?[/code]

Rsync uses its own protocol and access to SSH server, therefore you don't need to use SecureBridge components in this case. You can execute rsync program directly.

I am indeed able to use 'rsync' directly.

However, as far as I understand, 'rsync' needs 'openSSH' to access an SSH server. That is why I was hoping to use SecureBridge with my Delphi application. Furthermore, I appreciate the fact that SecureBridge encrypts the keys.

The problem is that Rsync uses its own mechanism to use SSH protocol and we cannot influence it. Unfortunately you cannot use SecureBridge for Rsync.
