slave dns picking up on the master dns

Hi all,

I've set up a master dns, eg 10.0.0.1
and a slave dns, eg 10.0.0.2

when installing the slave dns, i've also pointed out the master dns through the expert setup.

Yet, how does the slave dns replicate from the master dns?

For some reason it just doesn't pick up on any zone alterations/ new zones :confused:.

Can anyone help me in the right direction?

Thanks in advance.

Till is currently working on a first steps guide for ISPConfig 3, so that might clear up a few things. :)

I hope so. The product is very nice. If i can get it to replicate with the slaves it would be perfect.

The current version does not repliacte the settings, it just manages different dns servers. It is planned to have a mirrot option in the next relaese. Until then you can either point the mydns of the slave server directly to the master database or you use mysql replication without having ispconfig installed on the slave or you do a little modification in the ispconfig code that I described here for a mail setup:

http://www.howtoforge.de/forum/showp...27&postcount=3

Basically you edit the file /usr/local/ispconfig/lib/classes/modules.inc.php on the slave server and change the line:

Code:

$sql = "SELECT * FROM sys_datalog WHERE datalog_id > ".$conf['last_datalog_id']." AND (server_id = ".$conf["server_id"]." OR server_id = 0) ORDER BY datalog_id";

Code:

$sql = "SELECT * FROM sys_datalog WHERE datalog_id > ".$conf['last_datalog_id']." AND (server_id = 1 OR server_id = 0) ORDER BY datalog_id";

So the slave will now replicate every new or updated dns entry from the server with ID 1 (the master server) which is all you need for the replicated dns setup.

Okay, i found it, and i changed it.
Unfortunately it still doesnt pick up any addings to my dns1.

How can i troubleshoot to see wheres its going wrong?

Anybody, any idea to fix this?
I'm clueless :(

enable debugging in config.inc.php to check what the system is doing.

Ok, good one. Lemme examine whats going on :)

So, there is a form of communication, yet on the the slave i see nothing happening.

Just to be sure.

i create the domain on the master, i create the domain on the slave?
Or should it also appear on the slave automagicly?

Or am i doing something totally wrong?

If you changed the SQl as I explained in #4, then you dont have to create the domain on the second server.

If you did not changed sql, you will have to create the domain on the second server.
