(Free) DDNS recommendation?

[martinr]

I wonder how often my IP address actually changes, so I created a ddns-start script to send me a push notification (using Pushover) when the IP address is changed.

Let's see when I get the first one... (and how often next)

Notification by email? Could we see the script, please?

So what happened yesterday? Did your ISP change your IP address

A necessary reboot of the router and modem resulted in a new IP.

The ease of use of Asus’s service was a major draw. Also, they never asked for personal details like home address and such unlike no-ip which I thought I’d try. That really caught me by surprise. Anyways, still shopping around.

And your asuscomm.com subdomain address no longer resolves to your new IP address, I assume?

No, push notification.

It just pushes the first parameter of the ddns-start invocation, which is the new IP address, if I understand the Wiki correctly?

OK. So you won’t get a notification unless the Pushover device is on the LAN; you won’t get a remote notification?

Yup. Makes sense as I see the cert error in the logs.

My Pushover notifications are sent to an iPhone and iPad that both have cellular capabilities (and a SIM with a valid subscription inside), so I should also get them while being connected to a cellular network (instead of my or any other LAN).

Once you have it working, will you show us the ddns-start script and any other info on setting this up as.a fallback? Knowing the IP address, one can always use SSH local port forwarding to access the gui remotely (with SSH enabled, with PKI and an obscure port number).

Why don’t just use DNS-o-Matic to update those DDNS providers?
I see it supports a long list of ddns providers
https://www.dnsomatic.com/wiki/supportedservices

I am using afraid, no-ip, dynu.
Think dynu is good. Used it for few years.

There's nothing magical about it:

#!/bin/sh

notify() {
    curl -s \
    --form-string "token=..." \
    --form-string "user=..." \
    --form-string "title=..." \
    --form-string "message=IP: $1" \
    --form-string "sound=..." \
    --form-string "priority=0" \
    https://api.pushover.net/1/messages.json
}

notify $1

Sending a notification works (when I run the script manually), but I'm not sure whether I understood the Wiki correctly: will it be executed with the new IP when my WAN IP changes?

What's the advantage of this service?

I did have a look at it earlier this week, but I don't understand its purpose.

Isn't it just yet another possible point of failure added to the chain? (With what benefit?)

Basically dnsomatic is a centralised dns updater. Just set your router to update on dnsomatic and whatever ddns providers (dnsomatic supported providers) u set up in dnsomatic will be updated.

Meaning u can have multiple ddns all updated without doing your own custom script in Asus router.

I think dynu is good and stable. Best is no need activation every 30 days like no-ip.
https://www.dynu.com/DynamicDNS
The domain are provided by them unlike afraid,https://www.dynu.com/DynamicDNS

Why would you want to use multiple DDNS services? (Backup?)

I mean dnsomatic allows us to do that.
I used to use it along with opendns up sync and 1 ddns.
Tested afraid and noip then now using dynu.
As the router already set with dnsomatic, so all I need to do is go dnsomatic and change the provider I want.

Well, that was easy. Thank you!
Set up dynu with ease. No swimming through treacle as with Afraid. No need for a PhD in ddnsology. Then set up a dnsomatic account and finally updated the DDNS page on the router. Good riddance asuscomm.com.

Possibly spoke too soon: in the DDNS status box (second box down on WAN DDNS page), I’m showing “Request error. Please try again.” Re-entered and checked the dnsomatic details to no avail. Have you come across that? The Host Name (below WWW.DNSOMATIC.COM in the WAN DDNS page) is just the account/username for the DNSOMATIC account, isn’t it?

I found this https://www.snbforums.com/threads/dns-o-matic-ddns-setup.13148/#post-85623

but putting all.dnsomatic.com as the Host Name

and using the dnsomatic account/username in preference to the email, and the correct password, I’m still getting the error. I’ve set the dnsomatic preferences to always for email status reports and hopefully will get some clues.

The setup which I have is as follows:

Server: dnsomatic.com
Host Name: mydomain.mydnssservice.com
Username or E-mail Address: my dnsomatic account user ID (for example, JohnDoe)
Password or DDNS Key: my dnsomatic account password

The text above "mydomain.mydnssservice.com" should be changed to whatever your domain is called at your DNNS provider.

At first I was not sure what entries should go where, so found the above by trial and error. It seems to work

Method to retrieve WAN IP is “Internal”
for me I used “all.dnsomatic.com” as the host name. Many places suggest use “all.dnsomatic.com” or leave hostname blank if update client allows. But I think for Asus router, just put “all.dnsomatic.com”

Not sure if username is case sensitive. Just make sure they are the same.
Maybe also try a restart of router if recommended to see if a change of IP after restart will ensure the updater is working properly.

PolarBear, where have you been? Not seen your postings for quite a while.

Many thanks for your kind advice. I didn’t consider the host name might be that of the DDNS provider. I’ve just tried it without success, but tomorrow when my head’s clearer, I will start afresh and double check each step. Meanwhile, I went back to Afraid, with a successful resgistration, so if the IP address changes between now and tomorrow I can still get in.

Thanks again
