Following my fix: https://www.howtoforge.com/community/threads/slave-dns-not-reloading-zone-changes.79686/ Next day, testing some domains i get that my Slave DNS is refusing domain query connections, checked named.conf.local is empty. Restored backup from 2 days ago, all good now Any ideas?
If you have ISPConfig set to write to named.conf.local (which is normal), just put your changes in a different named conf file. If you really want them in named.conf.local, there is probably a conf-custom template you can use, though I can't easily verify that at the moment.
