HOWTO: Linux multihomed dns client - reverse lookup

The following thread is closed: 133552-howto-linux-multihomed-dns-client (Sorry I am not allowed to post URLs)

Therefore I write this append in an own thread.

The HOWTO in the referenced thread helped me a lot and I only want to append how to make reverse lookup working for a local zone:

One had to add the following lines:

Code:
zone "1.1.10.in-addr.arpa" {  // the reversed cluster of your local network
        type forward;
        forwarders {
                w.x.y.z; // your private name server
        };
};

The Linux resolver queries all nameservers in the order they are listed in /etc/resolver.conf. If a nameserver times out, it advances on to the following nameserver.

THREAD-KEYRING(7)					     Linux Programmer's Manual						 THREAD-KEYRING(7)

NAME
thread-keyring - per-thread keyring DESCRIPTION
The thread keyring is a keyring used to anchor keys on behalf of a process. It is created only when a thread requests it. The thread keyring has the name (description) _tid. A special serial number value, KEY_SPEC_THREAD_KEYRING, is defined that can be used in lieu of the actual serial number of the calling thread's thread keyring. From the keyctl(1) utility, '@t' can be used instead of a numeric key ID in much the same way, but as keyctl(1) is a program run after forking, this is of no utility. Thread keyrings are not inherited across clone(2) and fork(2) and are cleared by execve(2). A thread keyring is destroyed when the thread that refers to it terminates. Initially, a thread does not have a thread keyring. If a thread doesn't have a thread keyring when it is accessed, then it will be created if it is to be modified; otherwise the operation fails with the error ENOKEY. SEE ALSO
