Is my server up?

[dalecway]

Home #1 has a server and a fixed public IP. I use UptimeRobot to ping my router and let me know if it goes down.

Home #2 has a server and Internet is provided by Skylink. Skylink router is set to bypass so it acts only as a modem. Skyline does CGNAT so there is no good way to ping my router. I want to use UptimeRobot, but I don’t see any way to ping my router.

Both homes use Tailscale so I can definitely set up a batch file for each home to check on the other home. But I was really wanting to use Uptimerobot and Pushover to monitor it automatically.

Does anyone have any ideas on how I might accomplish this? As far as I can tell, Tailscale does not allow an incoming ping from the Internet.

@aaiyar were you running tailscale, or am I thinking of someone else?

@dalecway

Tailscale does not allow an incoming ping from the Internet.

Can be configured to permit this. Also, if you use Uptime-Kuma on both your servers, you can do everything you want to do (using Tailscale). UptimeRobot is not within your Tailnet, since it is a third-party web service.

Thanks for that. I’m glad you knew that he was running it.

I’ve read everything I can think of on Tailscale and not been able to get it to to accept a ping. I’ll research it some more. I’ll also look into your suggestion on the other third-party app. Thank you very much.

@dalecway

I’ll also look into your suggestion on the other third-party app.

Think of it as a self-hosted version of uptimerobot. No third-party gets any of your data. All the monitoring is done locally on your network.

There are many people here who use Uptime-Kuma.

@aaiyar

Uptime-Kuma

Their documentation does say that Uptime Kuma is primarily designed for Linux environments.

I know I can run it in a docker, but I think I will pursue your other suggestion that Tailscale may allow an incoming ping.

@dalecway

Uptime Kuma is primarily designed for Linux environments.

That isn't correct. While the Docker version will run on any platform with Docker, the non-Docker version platform requires are as indicated below:

Well crap maybe I didn’t read far enough. I like this idea if it will work on windows so I’ll go back and read some more, thank you.

I thought about it a little bit more and finally, I ended up using IPV6. Now I have no issues whatsoever with my CGnat. I put the prefix part of my IPv6 address into UptimeRobot and it stays steady.
