Below you can find a clear configuration snippets to quicklyimplement logging configuration for BIND9. Logging configuration in BIND is, to me, quite obscure and unnecesarily complicated. This sample can be cut & pasted in named.conf (or named.conf.options in Debian / Ubuntu variants). The basis for this configuration was in [http://www.zytrax.com/books/dns/ch7/logging.html]

RNDC is an extremely useful utility bundled with BIND that allows controlling the DNS server in a fine-grained way. So instead of reloading the whole server to add a single record, you can issue a "rndc reload myzone.com" command and only that zone will be loaded without restarting the server.

1. Generate a cryptographic key

First we'll generate a crypto key that will be used to access the control channel of BIND:

dnssec-keygen -a HMAC-MD5 -b256 \

Hay muchas situaciones donde manejar actualizaciones dinámicas, y en lo posible automáticas, de zonas de DNS es deseable. Por ejemplo en el caso de redes donde hay gran cantidad de estaciones que toman sus direcciones de DHCP o mediante otros mecanismos dinámicos (SLAAC en IPv6 por ejemplo).

Here you find the slides on Fast Flux Service Networks that I presented at LACNIC 12 in Panama City. Both Spanish and English versions are provided.

Files with the string "_EN" in their name are in English.

Files with the string "_3h" in their name are handouts with three slides per sheet.
