I can confirm the version of Bacula in Fedora 16 you're mentioning is compiled with the xattr support. If you want to try a later build with the same version you can download the latest update which is still in updates-testing. To install you should do (as root): yum -y --enablerepo=updates-testing update bacula-\* Here are the update requests with the changes: https://admin.fedoraproject.org/updates/bacula-5.0.3-17.fc16 https://admin.fedoraproject.org/updates/bacula-5.0.3-17.fc15 The line that states "POSIX.1e" capabilities in the changelog is only relevant to the enablement of bacula-fd regarding the ReadAll capability (-k). Ok interesting I'm currently looking at this code as I'm not so sure it wise to use that if you want to save acls and xattr successfully. I still have to see how this priviledge stuff works on Linux but we might need some more to be able to save acl and xattr data. Otherwise you can try the latest 5.2.3 backported from rawhide: http://repos.fedorapeople.org/repos/slaanesh/bacula/ http://repos.fedorapeople.org/repos/slaanesh/bacula/README.txt For now I just compiled the code myself so that I can run a debugger on it. But I think I have found the problem. First of all we have a snarfu due to fixing bug #1610 see http://bugs.bacula.org/view.php?id=1806 for those interested. We currently save on Linux and OSX one and only one xattr for any file. The fix for that was obvious and is commited. I also created a second bug for the posix file capability restore issue. Because when I fix bug 1806 the backup of the posix file capability works and the restore also (when I strace the process I see the restore of the data taking place.) But we run into an other problem as Bacula restores the mode and owner later on and does a chown and chmod on the restored file and that clears the posix file capability. For those interested: http://bugs.bacula.org/view.php?id=1807 I need to think how we are going to solve that. Marco -- Write once. Port to many.

Ok.

Why? Wont using 0.0.0.0 as listen address work?

The config is parsed at startup time, so no reasonable %n will be there.

You should be able to use a hostname there. Either fqdn or just a
hostname.
If this hostname has to point to a different IP on each server, you
could
a) use some small DNS-Server to provide the correct entry for that
subnet, e.g. dnsmasq, overriding the default hostname
b) if the servers in differnet networks have their own search pathes,
just add the bacula-sd-host as unqualified name and resolvie it via the
dns
c) just place an appropriate entry in /etc/hosts
