Please help separate IP addresses in BIND9 query log
I Have Installed BIND9 on my system.My log file (named_query) has the logs of each of the clients ( in my network
But I want to see the logs of each client separately in files like /var/log/named_querylog.x.x.x.x where x.x.x.x is the ip address of the each client
Can any one help me write a startup Script or some other way to do this?

have you tried grep, awk, perl or something?

i am happy with your solution
please help me with a sample rsyslog.conf file

I have no solution at all.
I can only to suggest you something, but actually I have a simple idea, you can grep out lines for every host:
grep logfile > log.

Regex to find old-style (dotted quad) IPs

This uses extended regex rules, so use with egrep, sed -r, etc.

With syslog-ng it can be done to create a file per detected entry in the logged messages. In syslog-ng.conf you can define a custom parser:

parser foobar {
            db_parser(file("/root/patterns/rules.xml")); };

options { create_dirs(yes); dir_perm(0755); };

destination baz { file("/var/log/collection/$FOO_ADDRESS.log"); };
log { source(src); parser(foobar); destination(baz); };

with an XML entry like:

<patterndb version='3' pub_date='2012-07-25'>
  <ruleset name='get_adress' id='5010'>
      <rule id='5010001' class='system' provider='reuti'>
          <pattern>from: @IPv4:FOO_ADDRESS@</pattern>

and use $FOO_ADDRESS for the file destination entry like outlined above.

Maybe this has an equivalent in rsyslogd.


The above will scan all messages (it could be limited to named though) for entries: “from:”
