I was unable to find any articles to answer this question, so my best bet was to post this here:

Scenario We have 2x application servers in production hosting a PHP website and I would like some folders to be syncronized between the 2, the same was setup for the development environment with no issues, I've followed all instructions from the URL "http://www.cloudedify.com/synchronising-files-in-cloud-with-csync2/", I still seem to have the same result, firewall has been disabled on both boxes for troubeshooting purposes:

Config Files: cysnc2.cfg

nossl * *;

group production {
   host server1;
   host server2;

   key /etc/csync-production-group.key;

 include /etc/httpd/sites-available;
 include /xxxxxx/public_html/files

 include /xxxxxxx/magento/media/catalog/product
 include /xxxxxxx/magento/media/brands

   exclude *.log;
   exclude /xxxx/public_html/file/cache;
   exclude /xxxxx/public_html/magento/var/cache;
   exclude /xxxx/public_html/logs;
   exclude /xxxxx/public_html/magento/var/log;

   backup-directory /data/sync-conflicts/;
   backup-generations 2;

   auto younger;

}

/etc/xinetd.d/csync2 csync2.cfg service csync2 { disable = no flags = REUSE socket_type = stream wait = no user = root group = root server = /usr/sbin/csync2 server_args = -i -D /data/sync-db/ port = 30865 type = UNLISTED log_type = FILE /data/logs/csync2/csync2-xinetd.log log_on_failure += USERID }

I've made sure that the daemon is listening on both server on port 30865 and the keys matched on both servers

I've run a tcpdump on each server, output as follows:

Is there anything else i'm missing or should be doing?
