First get the nameserver setup working
You should use a single file for the
komentari.info zone. And if you specify NS records you also should specify the their A records (sometimes called the glue records).
Then test with
dig if you can lookup the nameservers
Code:
$ dig -t ns komentari.info.
If dig returns you the nameservers then use them to do to lookup the address of panel.komentari.info.
Code:
$ dig +norecurse panel.komentari.info @208.84.149.210
Then repeat for the second nameserver
Code:
$ dig +norecurse panel.komentari.info @208.84.151.35
