What your machine needs

Two different sets of requirements apply, and mixing them up wastes an evening:

Flotera’s own requirements are small. If the machine runs Linux with a working NVIDIA driver and can reach the internet, the agent installs.
The marketplace’s requirements are the strict ones. Vast.ai and Clore.ai each demand specific kernel settings, open ports and network speeds before they will list a machine.

You do not have to research the second set. Install the agent first, then run the readiness check from the machine’s card — it measures the real hardware against the current thresholds and tells you what to fix.

For the agent

What	Requirement
Operating system	Linux with systemd
Privileges for install	`sudo` once, during installation
NVIDIA driver	already installed and working
Outbound network	HTTPS to `agent.flotera.com` and `get.flotera.com`

The installer does not install the NVIDIA driver. That ends in a reboot, and an installer should not turn “add monitoring” into “restart the server”. Install the driver yourself, or install the agent first and use the driver update command from the panel when you are ready for the reboot.

For the marketplaces

These change without notice, so Flotera keeps them in a catalogue with the date each threshold was last verified, rather than hardcoding numbers that quietly go stale.

What gets checked, in general terms:

Kernel settings that allow reading hardware sensors.
Access to GPU memory temperatures, which some configurations hide.
PCIe link width, because a card in a narrow slot underperforms.
Open ports the marketplace needs, scaled to how many GPUs you have.
Network speed measured from outside, not self-reported. Vast.ai scales its bandwidth requirement to how much video memory you are offering.

The check names the consequence, not the config line: you get “renters will not see this machine because the measured upload is below the threshold for 80 GB of VRAM”, not a line number.

Run it before you list, and again after any change to the machine.
