HI all,
first Eduardo:
I did an upgrade with the mentioned package to 9.9.1 P1, it´s now up and
running but doesn´t fix the problem.
I have to correct one thing: It´s not a 10.6 client system it´s a 10.7.4 Server
system, this is important because the client running this server does configure
bind with Apple´s Admin Tools. When something doesn´t work he calls me and I
log in via ssh and try to figure out what´s wrong. Telling the truth: I like vi
very much...

Sorry, was late last night for me so here are some parts of the configuration:
/etc/named.conf
include "/etc/rndc.key";
options {
directory "/var/named";
listen-on-v6 port 53 {
"none";
};
allow-recursion {
any;
};
allow-transfer {
none;
};
};
controls {
inet 127.0.0.1 port 54 allow {
"any";
} keys {
"rndc-key";
};
};
acl "com.apple.ServerAdmin.DNS.public" {
any;
};
logging {
channel _default_log {
file "/Library/Logs/named.log";
severity info;
print-time yes;
};
category "default" {
"_default_log";
};
};
view "com.apple.ServerAdmin.DNS.public" {
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update {
none;
};
};
... around 15 working master zones
zone "95.191.213.in-addr.arpa" IN {
type master;
file "db.95.191.213.in-addr.arpa";
allow-transfer {
com.apple.ServerAdmin.DNS.public;
};
allow-update {
none;
};
};
};
};
The lines of question in the db-file:
10800 IN NS ns1.hektor.de.
10800 IN NS ns2.hansenet.de.
3.95.191.213.in-addr.arpa. 10800 IN PTR mailserver.hektor.de.
The name of the server is ns1.hektor.de.
Trying to send an email to a server trying to get the PTR record the sender
receives an "Undelivered Mail..." mail with this:
550 inconsistent or
no DNS PTR record for 213.191.95.3 (see RFC 1912 2.1) (in reply to RCPT TO
command)
Hope this helps to clear out the problem
Best regards,
Mike
