Hi,

Yesterday, i was doing a upgrade from CentOS 5.3 to CentOS 5.4, which was resulting i following situation.

After doing the upgrade, named failed to start. Starting from command line gave me following error:

Code: 
Error in named configuration:
dns_rdata_fromtext: /var/named/intetdomæne.dk.db:10: near 'hostmaster.intetdomæne.dk.': bad name (check-names)

zone intetdom\230ne.dk/IN: loading master file /var/named/intetdomæne.dk.db: bad name (check-names)
_default/intetdomæne.dk/IN: bad name (check-names)

As you see, bad configuration file. Normal domain names were loading normally, but IDN names with characters as æ, ø and å were not. They were escaped!

Solution was to delete the domain from the DNS manager in DirectAdmin, and adding it again.


I suggest that DirectAdmin converts those IDN names to the xn- variant, when adding it as a new domain. This will hopefully prevent any issues later..
 
I just have the same bug, with a subdomain, without specials characters, but ending by -

So, subdomain like xxxxx-.domain.tld gives this :

Code: 
Mar 14 20:27:01 s004vps401 named[1568]: /var/named/domain.tld.db:21: google-fr-perso-sub-dom-n3o-google-fr-perso-sub-dom-n3o-titvin-.domain.tld: bad owner name (check-names)
Mar 14 20:27:01 s004vps401 named[1568]: zone domain.tld/IN: loading from master file /var/named/domain.tld.db failed: bad owner name (check-names)
Mar 14 20:27:01 s004vps401 named[1568]: zone domain.tld/IN: not loaded due to errors.

And all domain do not answer.

If something is unacceptable, it should be refused by directadmin, to avoid this sort of problem.

I run DirectAdmin 1.421
 
Well thats an invalid subdomain it shouldnt of even allowed you to create it.
