#Smokeping

Because I keep forgetting and it takes me far too much time to go through one of my million sites where I set this up and find the right config...

To allow a USG (Unifi Security Gateway) to reply to external (WAN) ping requests, do the following:

• Head to the Unifi dashboard -> Settings -> Firewall & Security
• Create a new rule
• Type: Internet Local
• Description: Allow Ping (Echo Request)
• Rule Applied: Before Predefined Rules
• Action: Accept
• IPv4 Protocol: ICMP
• IPv4 IMP Type Name: Echo Request
• Apply Changes -> wait ~2 minutes

That's it...

I've revamped my Smokeping infra a bit since 2020.

First off, starting to use the smokeping.eu¹ domain that Bianco got 10 or so years ago instead of using weird URLs under superuser.one domain.

It's running on four nodes as we speak:

• a virtual machine on a colocation server in Leaseweb, Amsterdam, NL -> leaseweb.nl.smokeping.eu
• a RPi3 (+SD card, slowest of all), Telenet, Belgium -> telenet.be.smokeping.eu
• a RPi4, EDPnet, Belgium -> edpnet.be.smokeping.eu
• a RPi4, Starhub, Singapore -> starhub.sg.smokeping.eu

This is achieved using Smokeping in a docker container, Cloudflare tunnel and Cloudflare CDN/DNS.

Back in the days -- when I was 16 or so -- Smokeping was the rage. Every colo provider in Amsterdam, every NOC, they all had their own Smokeping.

Playing around with Docker I saw some Smokeping image and that made me want to set it up again.

I'm running Smokeping on my server in Amsterdam (Leaseweb colo): smokeping.rootspirit.com.
