Title: Ping testing online
Post by: Weaver on December 25, 2020, 12:41:38 AM
I remember dimly that there used to be a highly useful service where a server would regularly ping some destination and then email you if there were no responses to the pings (perhaps within some configurable limits). I just can’t remember where it was - I’m thinking that it died for some reason.

I would love to find an equivalent. Any ideas?

Such a service has to be hosted online, can’t be from a machine in my own network, for reasons I won’t bore you with.

The requirements are that I need to know if a particular device, in this case my 3G USB ‘dongle’ NIC, goes down as seen from the internet side of things; can’t ping it from within the LAN here as that would not be a sufficient test to cover all types of failure.

And I’m not talking about single manually initiated pings here, has to be continuous monitoring.

Ping plotter? Smoke ping?

There's a few similar services.

A nice comparison list here: https://www.comparitech.com/net-admin/best-alternatives-to-pingplotter/

This may be the one you're think of, it's been around a while.

Trouble with f8lure was I used to forget to sign in every 30 days.

Many thanks, just what I needed. The every 30 days thing is going to be a really major nuisance, shame there isn’t a paid version.

I have set up a test with f8lure but stupidly I forgot to sort out firewalling, so the ping tests are failing, unsurprisingly, and I thing that zealous firewalling blocking ICMP is the answer. I tried to make a firewall hole just for one dest IP address and for ICMP only but I haven’t got it sorted out yet. Duh.

With the f8lure ping tester, what is the source address the pings are coming from ?
