Thank you for snippets :)

Very awesome!!!! Thank you!!!!

Don't forget to do a "sudo systemctl enable noip2.service" to enable this and create the proper symlinks. Then it will run on reboot.

Thanks! Wrote this myself WAY too many times... but this one is more reliable, somehow.

Thanks!

Thanks! Couldn't get mine to work...

Thanks! Works like a charm :)

Perfect! Worked right out of the box for Ubuntu 18.04 LTS. Thanks for sharing!

Awesome

Thanks!

Thanks dude, that's great for a lazy ass like me :-)
Awesome!

Thank you very much. It saved me several hours as I've ever remember them.

Thanks!

So I think there is a problem. I don't think it re-runs this periodically to update network changes (at least it does not on my machine). Is there a change we can make to do this?

I figured it out. It turns out the noip2 binary defaults to updating only every 30 DAYS (not minutes). Oddly, you have to do this to change the config file default:

pkill noip2 # stop running daemon
/usr/local/bin/noip2 -U 30 # rewrite /usr/local/etc/no-ip2.conf files with new data
/usr/local/bin/noip2 # restart actual daemon; previous step does NOT do this

I think the issue here is that when we go to the no-ip2 website we see that our ip hasn't updated for longer than the interval we set.

This happens because, with default values, noip2 only sends updates when the ip changes.

If you want to change this default behavior, you'll want to change two values in noip2.c

• change the line #define FORCE_UPDATE 0 to #define FORCE_UPDATE 1
• change the line #define FORCE_INTERVAL (1440 * 30) to be the time period in minutes that you want to force an update. for example if we want to update every 15 minutes we should change it to #define FORCE_INTERVAL(15)

Once you have done this rerun make clean install.

Can anyone help me. When I check status, I always get :

What flags are you passing to the executable?

Thanks!
