To enable logging in the BIND DNS server, you'll need to modify the configuration file for the server. The configuration file is typically located at /etc/named.conf or /etc/bind/named.conf, depending on your system.
To enable logging, you'll need to add a logging statement to the configuration file. For example:
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
This will enable logging to the named.run file in the data directory. You can specify a different file name and location if desired.
To see all queries, you can set the severity level to dynamic, which will log all queries. Alternatively, you can set the severity level to debug to log all debugging messages, or info to log all informational messages.
You'll also need to specify the type of messages you want to log. For example, to log all incoming and outgoing queries, you can use the following statement:
category queries { default_debug; };
To log all zone transfers, you can use the following statement:
category xfer-in { default_debug; };
category xfer-out { default_debug; };
Once you've added the logging statements to the configuration file, you'll need to restart the BIND server for the changes to take effect. You can do this using the following command:
systemctl restart named
You can then view the log file using a text editor or the tail command to see the logged queries and messages.
Keep in mind that logging can have a performance impact on the DNS server, so you should only enable logging when troubleshooting problems or when it's necessary.
