nejde mi bind notify

[Ivo Panacek]

Zdravim vespolek.

Mam problem se spojenim dvou DNS serveru.
Master ma bind 9.2.1 (RedHat) a slave ma bind 8.2.3 (Debian),
coz by snad nemelo vadit.

Konfigurace je defaultni, vubec zadne speciality.

Master ma pro danou zonu spravny zaznam (v named.conf i vlastni soubor)
a slave je v nem uveden jako (druhy) nameserver.

Pokud slave server pustim, vytahne si spravne z mastera zaznamy
a serviruje:

Mar  4 15:11:27 slave named[27206]: hint zone "" (IN) loaded (serial 2003022201)
Mar  4 15:11:27 slave named[27206]: master zone "localhost" (IN) loaded (serial 1)

Mar  4 15:11:27 slave named[27206]: master zone "255.in-addr.arpa" (IN) loaded (serial 1)

Mar  4 15:11:35 slave named[27207]: Sent NOTIFY for "moje.domena.cz IN SOA 1078409459" (moje.domena.cz); 1 NS, 1 A
Mar  4 15:11:35 slave named[27207]: Received NOTIFY answer (AA) from 172.16.0.23 for "moje.domena.cz IN SOA"
Mar  4 15:11:42 slave named[27207]: Sent NOTIFY for "16.172.in-addr.arpa IN SOA 1078409459" (16.172.in-addr.arpa); 1 NS, 1 A
Mar  4 15:11:42 slave named[27207]: Received NOTIFY answer (AA) from 172.16.0.23 for "16.172.in-addr.arpa IN SOA"

Na stroji master to je videt:

Mar  4 15:11:27 master named[7963]: client 172.16.0.2#3998: transfer of 'nem.homolka.cz/IN': AXFR started
Mar  4 15:11:27 master named[7963]: client 172.16.0.2#3999: transfer of '16.172.in-addr.arpa/IN': AXFR started

Pokud ovsem master reloadnu (zvednute serial zony a v ni zmena),
master sice pise, ze posila notify:

Mar  4 15:14:18 master named[7963]: loading configuration from '/etc/named.conf'
Mar  4 15:14:18 master named[7963]: no IPv6 interfaces found
Mar  4 15:14:18 master named[7963]: zone moje.domena.cz/IN: loaded serial 1078409658
Mar  4 15:14:18 master named[7963]: zone moje.domena.cz/IN: sending notifies (serial 1078409658)

ale slave nijak nereaguje a zmenu si nevytahne.

Priznam se, ze jinde mi to funguje, ale bind moc do hloubky neznam
a notify protokol uz vubec, takze me nenapada, jak najit pricinu.

Domnivam se, ze ekvivalentni server (= stejna distribuce, stejne verze sw)
notifikaci uspesne posila i prijima, takze na masteru chyba asi nebude, ale nevim,
kam na slave dat pasticky. (S Debianem si prilis netykam a tohle je znacne stary stroj.)
