Tricky little problem, send signal to other machine without user
Hi everyone! I want to be able to send a signal to another machine on the same network, and have it trigger a script on that machine. Here's the reason why I can't just ssh: I don't have a username on that machine, but there is a user that is always logged on that I can do stuff on.
So, I want to have a script constantly running in the background on that machine, and from mine, essentially ping it, and have it run another script. I'm not really sure how to do this...I know the IP address of the machine I want the script on, so I was looking into using something called netcat (man nc).
Does anyone have any advice or suggestions?
Thanks!

systemd-machine-id-setup
SYSTEMD-MACHINE-ID(1) systemd-machine-id-setup SYSTEMD-MACHINE-ID(1)
NAME
systemd-machine-id-setup - Initialize the machine ID in /etc/machine-id
SYNOPSIS
systemd-machine-id-setup
DESCRIPTION
systemd-machine-id-setup may be used by system installer tools to initialize the machine ID stored in /etc/machine-id at install time with
a randomly generated ID. See machine-id(5) for more information about this file.
This tool will execute no operation if /etc/machine-id is already initialized.
If a valid D-Bus machine ID is already configured for the system the D-Bus machine ID is copied and used to initialize the machine ID in
/etc/machine-id.
If run inside a KVM virtual machine and a UUID is passed via the -uuid option this UUID is used to initialize the machine ID instead of a
randomly generated one. The caller must ensure that the UUID passed is sufficiently unique and is different for every booted instanced of
the VM.
Similar, if run inside a Linux container environment and a UUID is set for the container this is used to initialize the machine ID. For
details see the documentation of the Container Interface[1].
OPTIONS
This tool does not take any options or arguments.
EXIT STATUS
On success 0 is returned, a non-zero failure code otherwise.
