Hello I upgraded to squeeze. Bind was not installed. I installed debian packages of bind9 manually. Finally, it worked fine. 7 days after, it is impossible to connect to web sites, and resolve dns names. It is the TTL value... I don't understand the link between dns ispconfig database, wich stays good, and the zone database, wich must be in named.conf zone. I try to record again dns zone by ispconfig, but nothing happens, and I find nothing. Thanks...
Other fact, named.conf.local is empty : bind screen in ispconfig is the same than in the manual p. 204. I'm searching in this forum...
1) Check that the path to named.conf.local in System > Server config is correct. 2) Check ISPConfig System log in monitor for errors.
