[bind9] Kako nastavit CNAME vrednost, da bo response brez dodane "root" domene?

Dobro jutro.

Evo, nov dan, nov izziv.

Tokratni kontekst je Bing Webmaster Tools in "verification" process.

Tega hočem naredit skozi DNS.

Dokumentacija pravi:

Add CNAME (alias) record with name abc and value verify.bing.com.

In v bind9 serverju naredim:

abc IN CNAME verify.bing.com

Ter:

service bind9 restart

In potestiram:

dig abc.example.com CNAME @127.0.0.1

Ter dobim rezultat:

; ---- DiG 9.18.33-1~deb12u2-Debian ---- abc.example.com CNAME @127.0.0.1

No in ta odebeljeni del na koncu me zanima. Ali je možno CNAME nastavit tako, da bo za query "dig abc.example.com CNAME" vrnil samo "verify.bing.com", in ne "verify.bing.com.example.com"?

Skratka, kako za CNAME record nastavit, da server v response-u NE append-a še "svojo" domeno.

Da, za začetek pravilno copy/pastaš navodila :D

Še vsi smo se zaklali s pikami v bind zone fajlih ...

Well... vsak stavek se konča s piko. Lahko bi vrednost "verify.bing.com." dali nekje vmes stavka ali kej tazga.

But, whatever...

Res je, pika na koncu je rešila zadevo.

Najprej sem spremenil na "verify.bind.com.", pa začuda ni delalo. Potem pa na "verify.bing.com.", to pa je šlo skos.

Fantje, zlatega zlata ste vredni. Teeeenkkkjuuuu.
