When i was first time setting up powerdns with poweradmin,and then checked dns,everything was fine.But now after around year and some time,every powerdns powered server which i check gets error on following field: DNS servers responded ERROR: One or more of your nameservers did not respond: The ones that did not responded are: Ip adress of second nameserver I have identical configuration as i have it on bind,but on bind dns report is ok.And it seems this is problem because i was downloading with wget using several poweradmin powered servers,and noticed how sometime i get error "not resolving",but it was fine next second when i started download again. Any idea why is this happening ? Also here is example of bind zone: $ttl 38400 @ IN SOA ns1.nameserver.com. hostname.hostname.com. ( 1239984845 7200 7200 604800 86400 ) nameserver.com. 86400 IN NS ns1.nameserver.com. nameserver.com. 86400 IN NS ns2.nameserver.com. ns1.nameserver.com. 14400 IN A 127.0.0.1 ns2.nameserver.com. 14400 IN A 18.104.22.168 nameserver.com. IN A 127.0.0.1 www.nameserver.com. IN A 127.0.0.1 ftp.nameserver.com. IN A 127.0.0.1 m.nameserver.com. IN A 127.0.0.1 localhost.nameserver.com. IN A 127.0.0.1 webmail.nameserver.com. IN A 127.0.0.1 admin.nameserver.com. IN A 127.0.0.1 nameserver.com. IN TXT "v=spf1 a mx a:nameserver.com. ip4:127.0.0.1 ?all" Only different between bind and powerdns/poweradmin,powerdns has no dot on end of domain.
