rsync does not need a remote shell it will work happily on any locally mounted remote storage.

mig,

Install telnet on DNS-323 and use the mount command, alternatively the same can be achieved from the other machine, rsync exists on various platforms.

the rsync command:  # rsync -a remoteHost:/remote_dir /local_dir

fails with the following errors:

     rsync: Failed to exec ssh: No such file or directory (2)
     rsync error: error in IPC code (code 14) at pipe.c(86) [receiver=2.6.9pre3]
     rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
     rsync error: error in IPC code (code 14) at io.c(453) [receiver=2.6.9pre3]

I believe this is because rsync tries to connect via ssh (or optionally rsh) which DNS-323
does not have binaries for.
I did get rsync to work, but I had to setup a rsync daemon on the remote machine.

As root on the remote machine, Kurobox (FC4) 192.168.1.12
1. I created the /etc/rsyncd.conf file:

log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock

[data]
  path = /data
  comment = data area
  use chroot = no
  hosts allow = 192.168.1.11
  list = yes
  auth users = root
  secrets file = /etc/.rs_sec

2. I created the /etc/.rs_sec file, on each line is a 'user:password' entry
(these users are independent of system users/passwords):

root:password

3. started the rsync in daemon mode

# /usr/bin/rsync --daemon

you can view the logfile /var/log/rsyncd.log for errors


On the DNS-323 192.168.1.11
1. modify the path (not sure if this is absolutely necessary)
# export PATH=/mnt/HD_a2/lnx_bin:$PATH

2. change to lnx_bin directory
# cd /mnt/HD_a2/lnx_bin

3. created the local directory
# mkdir /mnt/HD_a2/data
# chmod 777 /mnt/HD_a2/data

4. run the rsync command:
# rsync -av root@192.168.1.12::data /mnt/HD_a2/data

when rsync asks for root password I entered the text I put in the password part
(after the ':') of the /etc/.rs_sec file on the server.  In my case I entered 'password'

Since the rysnc daemon user/password is independent of the system users, I did have some permission problems.
On the server Kurobox (as root), I fixed the permissions with the following commands

to make sure each file is readable by others
# find . -not -perm -o+r -exec chmod +r {} \;

to make sure each directory is readable by others
# find . -type d -exec chmod +rx {} \;
