my question is a little bit more complicated, hece the ambiguous title.

My setup: I have a RaspberryPi, running the standard Pi distro, and a computer running Linux 16.04 in the same local network with fixed IP adresses. The Pi is used to wake the computer by sending a Wake-on-Lan package and then tunnelling onto the computer via SSH.

My question: Is there an easy and simple way for the computer to send a message to the Pi, which the Pi then interprets as the computer having started up succesfully and being reachable?

I already have set up a system where the Pi is continuously pinging the computer until it gets a response, but I specificly want to have the computer message the Pi and not the Pi checking up on the computer.

If anyone has an idea how to implement such a system, I'd be very grateful.
