rsync - Apr 2002 - remote to remote sync

Hi all...

Sorry if this has been covered before, I'm new to the list and couldn't
find anything in the archives.
Aside from the authentication issues, is it possible to run a rsync cronjob from
a local box that sync's two remotes boxes ?

...something like...

rsync -avg -em ssh user@123.456.678.123:path/to/some/files
user@345.456.567.667:/path/to/backup/files

I have worked out the authentication issues with SSH so all that's left is
rsync's ability to sync two remote systems from a local cronjob on a third.

Regards

Not as such; you can get pretty close though.

Just ssh to the first box, and run rsync from there to the second:

ssh -A host1 rsync -ave ssh ~/work otherhost:/backup/

Or, indeed, put the tail end of that command directly into the cron
job on either box.
