De server is linux. The client is Windows (with Cygwin)
In a program (delphi 6) I execute with TDosCommand the line
rsync -vrtz --password-file=c:\cygwin\secret --delete SRC user@linux_server::module
Yes it works.
Now let me make an ScSSHClient connection.
Yes it connects
I close 873 on the server
Now port forwarding:

Code: Select all

ScSSHChannel1.DestHost:= address of linuxserver or 127.0.0.1 or localhost;
ScSSHChannel1.DestPort;=  873
Direct:= FALSE;
Remote;= FALSE;
Sourceport:= 873
Connect;

Yes it connects
Now execution of the rsync line
Nothing is happening looks like hanging
Are there any suggestions what might be wrong?

The TScSSHChannel component does not execute commands.
For commands execution you can use the TScSSHShell component.

I don't expect the ScSSHChannel to execute a command.
The only thing I expect is that this component listens to SourcePort and sends the
data to DestPort on the Server. (Desthost)

On the Server a rsync daemon listens on port 873
On the client a rsync client program sends data to port 873
When port 873 is firewalled on the server I expect the ScSSHChannel to redirect the data stream via the SSH connection
As explained it does not work. What can I do to troubleshoot??

In order to solve this problem, perform the next steps:

1. Check, that the rsync client program sends data to the host, where ScSSHChannel1 listens the port 873.
2. Specify ScSSHChannel1.DestHost := '127.0.0.1'.
3. Find the sshd's server config file and set the AllowTcpForwarding parameter to yes.
