Thanks for taking the time to reply Michael. I've tried what you
suggested and rsync seems to work on the client. See below:
-bash-4.0$ ssh -l david aragorn "/usr/bin/rsync --version"
rsync version 3.0.3 protocol version 30

I've tried to rsync a file between two directories on the client:
-bash-4.0$ ssh -l david aragorn "ls /home/david/etc"
ls: cannot access /home/david/etc: No such file or directory
-bash-4.0$ ssh -l david aragorn "rsync --numeric-ids --perms --owner
--group -D --links --hard-links --times --block-size=2048 --recursive
--ignore-times /etc/resolv.conf /home/david/etc/"
-bash-4.0$ ssh -l david aragorn "ls /home/david/etc"
resolv.conf
-bash-4.0$ ssh -l david aragorn "cat /home/david/etc/resolv.conf"
# Generated by NetworkManager
domain wraige.com
search wraige.com
nameserver 192.168.1.254
So that certainly works. I'm no expert with rsync, and I don't know how
to get it to transfer between the server and client, but from what I can
see ssh is working and rsync is working.
Any other thoughts?
Thanks,
David
