Hi all,

I have problems to make rsync-backups inside of OpenVZ-Containers. I'll 
try to explain the problem with the following three cases:

1) Direct backups of a host-server as user 'backuppc' and *with* sudo
-> ok
2) Backup inside of a VPS as user 'backuppc' *without* sudo
-> ok
3) Backup inside of a VPS as user 'backuppc' *with* sudo
-> it stalls!

On the server side, I see the following:

<--->
CheckHostAlive: returning 26.238
full backup started for directory /etc (baseline backup #3) started full 
dump, share=/etc
Running: /usr/bin/ssh -q -x -l backuppc domain.name sudo /usr/bin/rsync 
--server --sender --numeric-ids --perms --owner --group -D --links 
--hard-links --times --block-size=2048 --recursive --ignore-times . etc/
Xfer PIDs are now 31562
xferPids 31562
Rsync command pid is 31562
Got remote protocol 1768191329
Fatal error (bad version): audit_log_user_command(): Connection refused

Checksum seed is 1869373300
Got checksumSeed 0x6f6c5f74
<--->

On the client side I see the rsync process, but it seems to be idle! 
Maybe the process waits for something?!

In relation to https://bugzilla.redhat.com/show_bug.cgi?id=401201 the 
'Connection refused' error should be harmless. However, is it possible, 
that this error prevents rsync from data-transfer?

I guess the reason for the problem is the CentOS-VPS. Backups from a 
Debian-VPS with sudo rsync work well!

Any hint is welcome!

Holger
