BIND8_NAMED2DLF.IN(1)

NAME
bind8_named2dlf - convert BIND8 named logs into dlf format

SYNOPSIS
bind8_named2dlf

DESCRIPTION
This script converts each line in a BIND8 named log to a dnszone dlf record. It is tested using Bind 8.2 logs. We're not aware of any changes in the logging format in any Bind 8.* version, we expect any bind 8.* log to get processed fine by this script.

The following lines are recognized:

•   approved/denied AXFR requests

•   completed zone transfers

•   loaded master and slave zones

•   denied dynamic DNS updates

DLF format
The DLF format of the dnszone superservice is

server
    Name of the DNS server

time
    Timestamp for the request

axfr_host
    IP address of the host requesting the AXFR

axfr_zone
    Name of the zone being requested

axfr_what
    approved, denied or axfr

loaded_zone
    Name of the zone just loaded

loaded_serial
    Serial of the zone just loaded

loaded_role
    master or slave

updatedenied_host
    IP address of the host requesting the update

updatedenied_zone
    Name of the zone being updated

Due to the nature of the different meanings of the lines in the logfile (not every line has both a AXFR-request, loaded a zone and gotten an update request), one or more fields can be replaced by a 0 or a -. These fields are automaticly filtered out for the different kind of reports.

Example of DLF lines are:

AXFR approved
    tim 1026644876 10.10.10.1 algron.com approved - 0 - - -

update denied
    tim 1026645567 - - - - 0 - 10.in-addr.arpa 10.199.16.218

master zone loaded
    tim 1026525210 - - - nigelbowen.com.au 2002071301 master - -

EXAMPLES
To process a log as produced by bind8:

 $ bind8_named2dlf < named-log

bind8_named2dlf will be rarely used on its own, but is more likely called by lr_log2report:

 $ lr_log2report bind8_named < /var/log/named
