apart from my problems when importing a Zone file there are also other problems. 1) Master-Slave replicants When having many DNS-Servers where one is the Master and two are the Slaves there is no easy option for defining those. First you have to define the servers who you want to replicate to in the main menu and then you need to add two entries in the Secondary DNS-Zone section. However they only replicate if you start and stop bind manually on the Master server. (I don't know why this doesn't work automatically.) When using a slave server that is not running with ISPConfig and you use the ISPConfig as a Master you have to do this as well. maybe this is a bug? 2) Trusted acl's normally the trustes acl's would go into the named.conf.local however that is totaly overwritten by ispconfig. putting it in the named.conf.options works - is this update-safe? 3) add replicate servers in webinterface When you use the field for adding servers you want to replicate to you get displayed a list of ALL Servers (not only DNS-Servers) klicking on one will add it to the field - then you type a comma and try to add a second server - and the first entry gets changed ... I have two problems with this. a) this field should only list DNS-Servers ... everything else makes no sense. b) klicking on a second server should add the second server - not change the first entry (there are sanity checks nonteless so you can check for duplicates AND add a second entry.) 4) Main Menu "DNS" usability problems. a) when you click on "DNS" in the main-navigation you get a list of all DNS entries. Good. b) when you are somewhere inside the menu you have to click on DNS to get back to the list wich is the 4th entry on the left-side which is somewhat painfull because we always click the topmost item to get to the main list ... but maybe that is just my company... thanks for your answers.
