rsync - Oct 2005 - Rsync over SSH-tunnel A->B->C using daemon on C

Dear,

I'm trying to put up a scripts to synchronize my computers (HOST_A and 
HOST_C). I can connect both via HOST_B to avoid the firewall.
I am trying to work with the rsync daemon to avoid hanging.

I tried to figure out the mailinglist + FAQ, how to do it, but it seems 
I misunderstand something, since all your previous help did not work for 
me.
I get the following error when executing the rsync-step:

Failed to connect to HOST_C: Connection timed out (116).

The scipt I now use is:

# On HOST_A the following commands are executed

# Start rsync daemon on HOST_C and check rsyncd.conf file
ssh HOST_B ssh HOST_C rsync --daemon
ssh HOST_B ssh HOST_C cat /etc/rsycd.conf

# Create SSH-tunnel
ssh -fN -l myusername -L 8873:HOST_B:8873 HOST_C

# Rsync folders
rsync -auv rsync://HOST_C:8873/module_on_HOST_C/folder_on_HOST_C 
/folder_on_HOST_A

# Close rsync daemon on HOST _C and SSH-tunnel
ssh HOST_C killall rsync
killall ssh

What you should check is:  (1) was the daemon actually started?  Or did
it complain (in the log file) and die?  (2)  Is the daemon configured to
listen on port 8873 instead of 873?  (You can force this with either the
--port=8873 command-line option or via the port option in the config
file.)

This connects to HOST_C and creates a tunnel from port 8873 on the local
host (through the ssh connection) to HOST_C, which will forward any
connects to HOST_B's port 8873.  It seems to me that you want to reverse
those hostnames.  (Aside: if you can directly ssh to HOST_C, you could
just rsync without daemon mode directly to HOST_C using ssh.)

/folder_on_HOST_A
You need to connect to port 8873 on *localhost* for the forwarding to
occur:

rsync -auv rsync://localhost:8873/module_on_HOST_C/folder_on_HOST_C
/folder_on_HOST_A
