Hi to all, I've installed Debian 6 in cluster mode, with mysql replica and file sync (/var/www and /var/vmail) and working very well. Both servers have 2 NIC, two IP addresses (one public, one private). How to configure the replication and file sync with unison to be done, over the private IP interface so that we don't incur any bandwidth charges? And second question is how to make ISPConfig to communicate in both direction? For example if add a new client on master server appear to slave after 1 minute, but don't work from slave to master. Thank you for great piece of software.
