[bind9] listen-on directive breaks status indicator

It appears that when I use the listen-on directive, the BIND status indicator in Management/Server/Services changes to OFFLINE although BIND continues to work perfectly fine.

/root/ispconfig/isp/conf/named.conf.master :

options {
( ... )
listen-on { 89.149.217.xxx; };
( ... )
};

/etc/hosts :

127.0.0.1 localhost.localdomain localhost
89.149.217.xxx jupiter.mydomain.com jupiter
89.149.220.xx1 neptune.mydomain.com neptune
89.149.220.xx2 mercury.mydomain.com mercury

ISPConfig is running on the same IP (Management/Server/Settings). There are 2 additional IPs on the system which I've entered in the field IP List. Does the status indicator check those IPs too? If so, that'd explain it, but I'd like to bind the nameserver (what a pun) to one IP and still get a correct status indication. Can this be done?

Thanks

PS: restarted bind and rebooted the server several times, there are no detectable errors in the logs

 

I believe that the check_services script checks for port 53 (Bind) on localhost.

Have a look at /root/ispconfig/scripts/shell/check_services.php

You can try to change the code:

Code:

    /*
     // Checke BIND-Server
    if(!$this->_check_tcp('localhost',53)) {
    $warning .= "Warning: service named not running (server: ".$server_name.")!\n\n";
    }
    */

to:

Code:

    /*
     // Checke BIND-Server
    if(!$this->_check_tcp('jupiter.mydomain.com',53)) {
    $warning .= "Warning: service named not running (server: ".$server_name.")!\n\n";
    }
    */

Edit by Clogboy: Please don't use the above, this code doesn't work. Please see solution by martinfst below.

 

Or add 127.0.0.1 to a listen directive in your bind options. (named.conf usually)

 

Thanks Clogboy and martinfst,

Editing check_services.php didn't work, but adding 127.0.0.1 to the listen directive did the trick. Probably better to keep it that way anyway, who knows what else might expect services to run on localhost, regardless of any "outside world" IPs.

 

Sorry 29net, I didn't check my solution before hitting the send button.
