[pfSense] How to Enable/Disable DynDNS update e-mail notifiations?

[Stefan Baur]

[I had already posted a similar message on 2014-06-27, but as it didn't
get any replies, I'm trying again, slightly rephrased]

Hi,

since upgrading to 2.1.3-RELEASE and enabling e-mail notifications under
"System: Advanced: Notifications", I'm receiving an e-mail whenever the
DynDNS update script ("Services: Dynamic DNS client") triggers an update.

I *do* want e-mail notifications, just not for such mundane things, only
when stuff breaks.

So how do I configure that?

I am not sure that’s how Dyn works?
As far as I understand it Dyn gets a request and it looks at the originating IP address, then makes the change.

I believe that it is possible to send DynDNS updates to IPs other than
that of the originating IP, I recall I have done that in the past with
the dyndns client (ddclient ) script. If you don't specify a specific
IP, it defaults to the origin source.

Yes, but that's not the question. The question is how do I
Enable/Disable e-mail notifications for "DynDNS update successful",
without disabling e-mail notifications in general?

After all, I *do* want to get notified when stuff breaks. I don't need
notifications for "everything is going well".

Yes - I know, I wasn't answering your question, I was giving input to
someone who had replied to your question.

It's supposed to update the DNS entry, yes, but I don't want to receive
an e-mail notification for each successful update, that's what I'm
looking to configure.

I don't want to disable e-mail notifictions in general, to make sure I
do get notified when critical stuff happens.

What I am saying it Dyn is the one that controls if it is updated or not.

You need to either write a custom PHP or bash script to do this - this function does not exist in the system happens today.

That's really not the point. The point is that I'm receiving alert
e-mails from *my pfSense installation*. Not from Dyn.

And the message of the alert is "DynDNS updated IP Address on WAN (em0)
to xxx.xxx.xxx.xxx".

It's perfectly fine that DynDNS performed the update. I do want it to do
that, and that works perfectly. No error or problem here, no complaint.

I just don't want to receive an alert e-mail for "things are going well".

It *should* email me when things break, so "turn all notifications off"
is not an option.

I totally get your point and you're ignoring my answer: IT DOES NOT EXIST AND YOU WILL HAVE TO CREATE IT ON YOUR OWN.

Can you hear me now?

There is no way to selectively disable that notification at this time.

If you don't mind a simple source edit, you can disable the notification
by removing or commenting out etc/inc/dyndns.class line 1027 (on 2.1.3)
it should start with "notify_all_remote"

Thank you. I just checked, it actually appears twice, once for IPv4 and
once for IPv6 (7 lines below the first occurrence), so I'm going to
comment out both.

(I'm kinda curious whether no one uses e-mail notifications in
combination with DynDNS, or why I'm the first to notice/complain. I
can't really imagine an "everything OK" e-mail being a desired feature
for DynDNS updates, given their frequency.)

Is there any chance of getting this disabled or made configurable via
WebGUI checkbox in one of the next few releases? Should I file a
bug/feature request?

Just saying, but I get one email a month; my WAN on Comcast DHCP. But if I
did get a change, I think I'd want to know. One more email is the least of
my problems, lol.

Jul 10 07:42:32 php: rc.dyndns.update: phpDynDNS (myhost.no-ip.org):
No change in my IP address and/or 25 days has not passed. Not updating
dynamic DNS entry.

Over here, DSL has dynamic IPs, changing with every reconnect and at
least every 24 hours (forced dis- and reconnect by the provider).
Multiply that with 40 pfSense installations, some of them on flaky DSL
lines that reconnect more than once a day, and you can figure out why
I'm currently not a friend of this feature. ;-)

Thanks to Jim Pingle, I now know how to turn it off.

Yes, it is in there twice but IPv6 DynDNS is still fairly rare so the
second one probably isn't going to be hit often.

It was put in due to demand. People wanted to be alerted when their IP
address changed. For most it's a fairly infrequent event.

It may be possible in the future, but unless someone submits a pull
request to add the option, probably not any time soon. You can look for
an existing entry on https://redmine.pfsense.org/ for it, if one does
not already exist, feel free to create a new feature request.

Thank you for explaining how I can disable it on my own.

Regarding the feature request, I'll see if I can make do with an
<earlyshellcmd> in my config files to disable that again upon each
upgrade. If it starts bothering me too much, or if I get around to it,
I'll look through the bugtracker and file a feature request if there
isn't one already.

Again, thanks for your help and your professional, helpful attitude in
your replies. :-)
