Hi,

I have two old servers with one mirroring the other using RSYNC over
SSH. I did this some time ago.

Now coming to replace these servers with two new F11 ones I cannot
seem to get the it to work without supplying passwords.

I followed my instructions I wrote at the time for RSYNC over SSH, but
it still asks for a password even though AFAICS I have set up the
certificates correctly.

Any help or suggestions welcome,
Make sure that the user's .ssh directory has the correct SELinux contexts
as
well as correct permissions:

$ ls -lZd .ssh
drwx------. rick rick system_u:object_r:home_ssh_t:s0  .ssh
$ ls -lZ .ssh
-rw-------. rick rick system_u:object_r:home_ssh_t:s0  authorized_keys
-rw-------. rick rick system_u:object_r:home_ssh_t:s0  id_dsa
-rw-r--r--. rick rick system_u:object_r:home_ssh_t:s0  id_dsa.keystore
-rw-r--r--. rick rick system_u:object_r:home_ssh_t:s0  id_dsa.pub
-rw-r--r--. rick rick system_u:object_r:home_ssh_t:s0  known_hosts
Okay, my F11 instillation did not have a .ssh directory, so I am getting
:-

[root@yyy ~]# ls -lZd .ssh
drwx------. root root unconfined_u:object_r:admin_home_t:s0 .ssh
[root@yyy ~]# ls -lZ .ssh
-rw-r-----. root root unconfined_u:object_r:admin_home_t:s0
authorized_keys
-rw-r--r--. root root unconfined_u:object_r:admin_home_t:s0
datacomms-net-key.pub
-rw-r--r--. root root unconfined_u:object_r:admin_home_t:s0 known_hosts

How do I go about changing the unconfined_u's to system_u ?
As root:

   # chcon -v -u system_u /path/to/userhome/.ssh/*

You can also try (as root):

   # restorecon -v -R /path/to/userhome/.ssh

Thanks Rick, the 'restorecon' done it nicely :)

RSYNC seems to be working without a password now !

No problem.  Remember that if you create things under your home
directory, SELinux may not take a liking to it unless you tickle it.
It's bitten me before, so I feel your pain.
