Logging of queries (and dnssec and so on) in Bind9 (apt-get install bind9) can be enabled in Debian using the following code in /etc/bind/named.conf:
logging {
channel default_file {
file "/var/log/named/default.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel general_file {
file "/var/log/named/general.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel database_file {
file "/var/log/named/database.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel security_file {
file "/var/log/named/security.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel config_file {
file "/var/log/named/config.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel resolver_file {
file "/var/log/named/resolver.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel xfer-in_file {
file "/var/log/named/xfer-in.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel xfer-out_file {
file "/var/log/named/xfer-out.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel notify_file {
file "/var/log/named/notify.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel client_file {
file "/var/log/named/client.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel unmatched_file {
file "/var/log/named/unmatched.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel queries_file {
file "/var/log/named/queries.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel network_file {
file "/var/log/named/network.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel update_file {
file "/var/log/named/update.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel dispatch_file {
file "/var/log/named/dispatch.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel dnssec_file {
file "/var/log/named/dnssec.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
channel lame-servers_file {
file "/var/log/named/lame-servers.log" versions 3 size 5m;
severity dynamic;
print-time yes;
};
category default { default_file; };
category general { general_file; };
category database { database_file; };
category security { security_file; };
category config { config_file; };
category resolver { resolver_file; };
category xfer-in { xfer-in_file; };
category xfer-out { xfer-out_file; };
category notify { notify_file; };
category client { client_file; };
category unmatched { unmatched_file; };
category queries { queries_file; };
category network { network_file; };
category update { update_file; };
category dispatch { dispatch_file; };
category dnssec { dnssec_file; };
category lame-servers { lame-servers_file; };
};Now just “mkdir /var/log/named/ && chown bind:bind /var/log/named && /etc/init.d/bind9 restart” and you’re done.
