rsync help needed please

English Applications
#1

Although I have read the man pages (although I admit, not ALL of it!) and can’t seem to figure out the wood from the trees.

Requirement:-
Rsync files from one suse11.0 machine to another suse11.0 machine. The files are owned by root and need permissions to be maintained.

rsync -avz /srv/www/htdocs/ 192.168.1.223:/srv/www/htdocs

Problem:-
When run manually, it prompts for a password (remote root) … when I enter the password it rsyncs OK.

I read that I can use a password-file option which I tried but it said:-

The --password-file option may only be used when accessing an rsync daemon.

I want to automate this command by adding it into a cron job but without this password, it’s not performing the task.

Does anyone have any suggestions please how I can get around the problem??

Hi
What about using the ssh option and generate some keys?

Hi,
as stated in the previous post, you have to generate a public ssh key and copy it to the destination’s authorized_keys, pls check this page:

hmm, i have followed the guide but it still prompts me for a password when i run the script or try to ssh?!

i’ve ensured th permissions are correct as per OpenSSH FAQ but still no joy.

Would it matter if I am trying to trying to do from server1/root to server2/root?

Hi
Is the sshd_config file modified ok to allow root login and have you
restarted the sshd daemon?

Look at the logs (messages) to see what it’s saying :slight_smile:

Yes, sshd is restarted and root allowed (i can ssh manually from computer1 to computer2 using root).

Ah, the logs - how I forget how useful they are!

I’m going back to re-read that guide and see if somehow I messed up!!

In the meantime, please any more suggestions are appreciated!

Bah! Silly VIM (ahem, of course, it was VIM’s fault and not mine!)

The key I had copied into the authorized_keys file has line breaks in it (hence I think the
in the messages file), I removed them so it was all on one line and now … IT WORKS!!

Thank you for suggestions and links!
