TinyDNS serving WAN IP

[Juel]

Hi,

I wanted tinydns to always serve my dynamic WAN-IP and just want to share some code
for people having similar problems. The code is far from perfect and I know this is not the way to go,
but I needed this running asap - thus didn't go through feature requests or create any ticket.

So this is in a few steps what you can do:

Step 1:

Enable ssh in "System -> Advanced" and connect with your ssh-client.
Open 2 sessions.

Step 2:

On first terminal press 12 - debug console:

pfSense shell: conf_mount_rw();
pfSense shell: exec

On second terminal press 8 - console:

open: vi /usr/local/pkg/tinydns.inc
find: function tinydns_create_zone_file()
insert after:

$fd = fopen("{$g['varrun_path']}/service/tinydns/root/data", "w");      
if(!$fd) {
	log_error("Could not open {$g['varrun_path']}/service/tinydns/root/data for writing.");
	return;
}

the following code:

/* replace "wan" by wanip */ 
for($x=0; $x< count($config['installedpackages']['tinydnsdomains']['config']); $x++) {
	if(strtolower($config['installedpackages']['tinydnsdomains']['config'][$x]['ipaddress']) == "wan"){
		$config['installedpackages']['tinydnsdomains']['config'][$x]['ipaddress'] = get_interface_ip("wan");
	}
}

Step 3:

open /etc/inc/services.inc

insert before function definitions: require_once("/usr/local/pkg/tinydns.inc");
find: function services_dyndns_configure($int = "")
insert below:

        /* update tinydns service */
        tinydns_create_zone_file();  
        tinydns_setup_ping_items();

Step 4:

You might need to restart

Step 5:

You now can enter "wan" instead of an ip in
"Services->DNSServer->Record Data" and it should server your wan-ip.

I think that Step 2 should be placed in /etc/inc/pfsense-utils.inc at
function reload_all_sync() - but I couldn't get it to work there.
Thus I put it in the services_dyndns_configure function, which probably only works with configured dyndns.

As it serves my needs I'm fine with it - if theres more interest it would definetly be worth opening a
ticket and having a delevoper doing things right.

Greets, Juel
