    nice

  • @Pzea or just simply switch to djbdns

  • Or simply do not use something that's not maintained for how long? 3 years now.

    Or get married to @serverian, have children with him, and your children will build their own CP :D

  • recursion should "always" be turned off, you don't want your server be part of a dns reflection attack.

    Kloxo or better use Kloxo-MR (mr is still being updated) and has way more functions!!!

    @Mun, if you have nothing usefull to say, then just say nothing...

    Pretty sure hooking up with @serverian is a useful suggestion. He's dreamy.

    for photonvps python shell

    wget https://www.photonvps.com/files/bindrecursion.py

    chmod 755 bindrecursion.py

    ./recursion.py

  • this is for Bind DNS ?

    All you will is end up as a brand.

  • Kloxo Official (6.1.12) not set 'recursion off' and not set 'allow-transfer' (for secondary dns). Kloxo-MR already set 'recursion off' and listing IPs for 'allow-transfer'.
