I have ISPConfig 3 installed. It's using MyDNS. I would like to have another DNS server in a different C subnet. maybe another MyDNS? Or bind? Or something else? Can someone point me to a guide or something for this? I bet it exist
If you use MyDNS, you can set up a slave DNS server using MySQL replication: http://www.howtoforge.com/how-to-set-up-database-replication-in-mysql-on-ubuntu-9.10
I just finished to install something like that. 1) set up ispconfig3 with BIND 2) set bind option to notify you client and allow client to transfer 3) add on the slave the zones with master your primary server pts0
