Hello,
I am trying to solve this problem with csync2.
To keep it simple , I made a simple test from server master(Anuket 192.168.1.30) to sever slave (Atum 192.168.1.31).
Eache server can be reached:
From Anuket:

The certification generated using the information from PAPER.
from the directory where the source is:
make cert
The csync2 key was generated:
csync2 -k /etc/csync2.key_mygroup
And then transfered to node2 (Atum):
scp csync2.key_mygroup root at 192.168.1.31:/etc/csync2/csync2.key_mygroupscp csync2_ssl_cert.pem root at 192.168.1.31:/etc/csync2/csync2_ssl_cert.pem
Csync2 was compiled using SSL support:
./configure --prefix=/usr --sysconfdir=/etc/csync2 &&make
Configuration os csync2.cfg the same file on both node (anuket and atum):
root at Anuket:/etc/csync2# cat csync2.cfg
