Unhappy Rsync going one way on Fedora 11, 12

hi everyone, i have set two machines (B&C Fedora 12) to rsync to one machine (A fedora 11) which acts as the backup. The two machines have restricted ports except for SSH which is not on a default port though. they all reside on the same local network and I used ssh keys to allow the sync to take place. The keys only work if the backup machine is getting to the two other machines (A--> B&C good) but those machines still prompt for a password to get to A (B&C -->A bad). The key transfer and setup procedure is set to run on root and is exactly the same procedure carried out on all machines.

From comp B
1) ssh-keygen -b 1024 -t rsa -f /home/Leo/.ssh/id_rsa
2) scp /home/leo/.ssh/ root@192.168.0.AA:/home/leo/.ssh/authorized_keys
3) rsync -r -e ssh /Backup leo@192.168.0.AA:/Backup/Backzip/BBZip
4) password prompt (Not supposed to happen right?)

I have done the same procedure on A and it works if its backing up to B although the point here is B to backup to A with NO PASSWORD prompt because this has to go into a cronjob Directory permissions are set to leo and root, anyhelp?

Are the permissions 0644 for authorized_keys? Also, and likely more importantly, if you are logging in to A as 'root' then it will be looking for /root/.ssh/authorized_keys. You should be able to glean some additional information from 'ssh -v -v -v root@192.168.0.AA' and reviewing for why it fails if the above items are satisfied and it still fails to login using key authentication.

thanks for the quick response

I had also set up the keys in the root home directory for root, let me check on the permission for authorized keys and will try and extract something from Verbose out put
