How do I enable Response Rate Limiting (RRL) on BIND 9.9.4?

BIND 9.9.4 (and higher) provides support for Response Rate Limiting (RRL).  However, it is not enabled by default when building BIND.  The reason for this is that BIND 9.9 is an Extended Support Version of BIND and per our policy on mangement of ESVs, we do not introduce any new features or functionality to a stable ESV version.

Therefore the activation of RRL as a new feature must be selected when building BIND via the new configure option --enable-rrl:

$ ./configure --enable-rrl

In the BIND 9.9 subscription-only releases (for example, 9.9.4-S3), RRL is always available, and there is no configure option to enable it.  This will also be the case in BIND 9.10.

    It isn't a valid option in the 9.9.4-S3 release? Did it get set as a default option?

    It's built-in to the subscription versions (and from 9.10 onwards). The reason we made it optional for 9.9 was that to do otherwise, was breaking the rule of 'no new features/functionality' for an extended support version. One of the reasons for the existence of ESV versions of BIND is to ensure that we provide stability along with necessary bug fixes only.

    [ Josh]: Redhat or CentOS 5.9 cannot compile BIND 9.8.6 and 9.9.4 2013-10-03 09:30

    Dear ISC,

    We are HKIRC, the registry of .hk ccTLD. We found that two new BIND 9.8.6 and 9.9.4 cannot be compiled in Redhat / CentOS 5.4 - 5.9.

    We can apply these two new BIND in Solaris 10, Redhat / CentOS 6.4 , and even the old Solaris 9.

    the following is my command using in compilation.

    for BIND 9.8.6 or older, and BIND 9.9.3 or older

    STD_CDEFINES="-DDIG_SIGCHASE=1"
    export STD_CDEFINES

    ./configure --prefix=/usr/local/bind-9.x.y --with-openssl --enable-threads
    make
    make install


    for BIND 9.9.4
    STD_CDEFINES="-DDIG_SIGCHASE=1"
    export STD_CDEFINES

    ./configure --prefix=/usr/local/bind-9.9.4 --with-openssl --enable-threads --enable-rrl
    make
    make install

    Would you help to check the problem?


    Regards,
    Josh
