DNS - zoufalstvi

[Petr Jodas]

Dobry den,
jiz nekolik dni se marne snazim rozchodit reversni domenu. Situace je uplne
jednoducha:

Mam dva stroje, jeden se jmenuje Asterix (s IP 172.17.31.44) a druhy Obelix
(172.17.31.45). Na Asterixu bezi Bind 9.1.3 a zkousel jsem na nem vytvorit
domenu "jodyn.jod". Domena sama o sobe bezi, dokonce bezi i reverzni zaznamy
pro localhost, ale reverzni zaznamy pro domenu "jodyn.jod" nefunguji.
Reverzni zaznam jsem zkousel prikazem "dig -x 172.17.31.44" a da mi
nasledujici vypis:

[root na asterix root]# dig -x 172.17.31.44
;; Got answer:

Tento vypis se mi zda jako chybny. Oproti tomu dotaz na 127.0.0.1 je zrejme
v poradku:

[root na asterix root]# dig -x 127.0.0.1

Kde je chyba ??? V oblasti siti pod Linuxem jsem zacatecnik, zkuste mi
prosim poradit. Pro jistotu jeste prikladam konfiguracni soubory bindu. Tato
domena nikdy nebude pripojena do jine site nebo do Internetu.

Dekuji Vam, s pozdravem
