This is one of the tokens discussed previously. But the flexibility afforded by this way of doing things is very powerful. Below is my error: When a query is run, the token is replaced with the appropriate value. To return absolute instead of relative hostname data, an extra “. This is correct operation, and BIND will be able to understand and use this data.

The MySQL connect function doesn’t accept a “connection string”. The main reason is that using the compile flags that you did, you should see those flags as part of the output when you start the named application.

Fortunately, the number of spaces in between doesn’t matter, as long as there is at least one. The first parameter myxql is used internally by the driver and BIND so you can just ignore it. Go ahead and populate the domains table with some dlzz. You can divide your data up into even more fields if you like, as long as the concatenation of the data makes sense to BIND.

This is one of the tokens discussed previously. Notice all the extra spaces at the end of the data string. Can you please advice?

The values of the fields may be held as integers, floats, whatever by the database, but the return from the MySQL functions is only a string. That is caused by the other fields in the row being NULL. These queries are then parsed and mywql tokens removed.

If zero rows are returned, the database does not support the zone i. Double quotes could not be used, as the entire DLZ command line is already inside of double quotes and msql escaping would be nasty.

Only if the zone is supported will the allowzonexfr query be run. If we have searched for the host name and not found it lookup will search for a “wild card” hostname. The data string is “built” by concatenating fields 4 through 12 together, with a space added in between each.

You can specify the appropriate directory if it is not found by appending a path to the MySQL configure option. A python script then creates the necessary entries in the postfix database to allow mail routing to occur. This query is used by allowzonexfr in the MySQL driver. The entire line above is one parameter located at argv[2].

This function takes five parameters and has the following signature:. If a result set for a lookup or authority query only has one mysqp, the driver will use the default value of “a” for type and for ttl.


Notice there are no characters or spaces between the brackets. Since the findzone function is run by the allowzonexfr function this query is also run when allowzonexfr is run.

This explanation will help the reader understand the next portion where I setup tables and views and populate them with data. The second parameter “-d 1” sets BIND’s debug level to 1. The next piece is the word “mysql”. Like the findzone query, the results returned by the allowzonexfr query are not really used, so what you return and in what order doesn’t really matter. The MySQL driver is smart enough, however, to properly escape the zone string.

This string must be in the proper format for BIND to use it properly. If compiling on a 64 bit system, you might have to setup some variables so that the appropriate mysql libraries are found: The chart below shows 12 fields but not all fields are required in all queries. This line is indented just to make it easier to read the configuration file.

MySQL uses thread local storage in its C api.
