DNS not running after upgrade from HPUX 10.20 to 11.0

[Rainer von Bongartz]

I had a primary DNS server for my domain running under HP-UX 10.20

After upgrading to HP-UX 11.0 named produces the following errors :

Sep 5 08:34:33 neptun named[4105]: owner name "bu_nt020.dil.de" IN (primary) is
invalid - rejecting
Sep 5 08:34:33 neptun named[4105]: db.dil:19: owner name error
Sep 5 08:34:33 neptun named[4105]: db.dil: line 19: database format error (A)

Do I have to change the layout of my database ???

[Tim Malnati · Accepted solution]

I suspect that the underscore character '_' is causing a problem. RFC1033 specifically allows them, but the character is not recommended in RFC1035. As a quick test you could change 'bu_nt020.dil.de' to 'bu-nt020.dil.de' and see if the database builds correctly. Hopefully you only have a few machines using the underscore character?

Tim is right. In your named.boot file, insert these lines at the beginning of you the file and then stop/restart named:

check-names primary ignore
check-names secondary ignore
check-names response ignore
