csync2 ERROR: Connection to remote host failed
- by Emil Salama
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;

}
/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?
