Tere!

Mul on probleem nimeserveritega, loodan, et keegi oskab aidata.

Nimeserverid jooksevad Bind 9 peal.
Kui secondary dns maha läheb, siis millegipärast ei ole enam võimalik domeene resolvida.

Veider on veel selline asi, et peale secondary dns mahaminekut, sain dnscheck.net kaudu sellise vastuse:

.........................
CheckDNS.NET is asking root servers about authoritative NS for domain
Got DNS list for 'cooper.ee' from NS.EENET.ee or NS.EENET.ee
Found NS record 'cooper.ee', but could not resolve it to IP, answer from 193.40.56.245: host 'cooper.ee' not found.
Found NS record: office.cooper.ee[213.219.118.142], was resolved to IP address by NS.EENET.ee
Domain has 2 DNS server(s)

CheckDNS.NET is verifying if NS are alive
DNS server cooper.ee failed and will be dropped from other tests
Error fetching SOA from office.cooper.ee [213.219.118.142], request timed out. Probably DNS server is offline.
0 server(s) are alive
No DNS servers alive, tests stopped

.........................

Kui aga secondary dns uuesti tööle panna, siis domeenid resolvivad sekundiga kohe ära. (Isegi kui secondary dns on ööläbi maas)
checkdns.net näitab siis, et kõik on korras:

CheckDNS.NET is asking root servers about authoritative NS for domain
Got DNS list for 'cooper.ee' from ns.ut.ee or ns.ut.ee
Found NS record: office.cooper.ee[213.219.118.142], was resolved to IP address by ns.ut.ee
Found NS record: cooper.ee[212.47.220.120], was resolved to IP address by office.cooper.ee
Domain has 2 DNS server(s)

CheckDNS.NET is verifying if NS are alive
DNS server office.cooper.ee[213.219.118.142] is alive and authoritative for domain cooper.ee
DNS server cooper.ee[212.47.220.120] is alive and authoritative for domain cooper.ee
2 server(s) are alive

Huupi lasen - äkki on esimene kogemata ainult forwarder/cache teisele?

Sama domeeni all asuvad domeeniserverid on alati tore kamm. Uuri tausta selliste asjade kohta nagu "glue records" dns-is ja vajadusel kurda eenetile. Paistab, et office.cooper.ee'st teab ns.eenet.ee paljutki (aga sellest pole suuremat kasu, sest nagu paistab, on see su maas-olev secondary) ja cooper.ee'st ei tea ta muhvigi.
