Setup on Linux -- Headless

[trleith]

I got a new computer and thought I'd make Folding@Home the first service I'd get going on it because (as I recall from the other one) getting the NVIDIA software to work was painful and, well, let's get it over with.

I see that a great deal has changed.

Here's where I'm at. I have it running, and by golly it sees me try to open the web control and redirects me, but the whatever it is at https://v8-3.foldingathome.org/machines says "No folding machines found"

I think possibly this might have something to do with allowed-origins but I'm not sure I'd expect anything at foldingathome.org to get through my firewall and I thought the point of the instructions here was to not require that.

What am I missing?

Thanks,
t

PS: I've been folding on the old machine a few years now. Is the F@H ID = [***really long string***] my passkey?

At the end of those instructions, the local URL to use is shown - http://localhost:7396/machines, not the foldingathome.org address.

Your passkey is your passkey, not your F@H ID. The F@H ID is used by the optional login you can create on foldingathome.org for monitoring systems either locally or remotely.

[calxalot]

F@H ID is a unique identifier for a client. It is not your account. Nor is it a passkey token.

[calxalot]

Note that Safari cannot access the local client from the https page.

[calxalot]

For linux headless install, see also

https://github.com/FoldingAtHome/fah-cl ... ssions/214

[calxalot]

To see a remote client, it needs to be linked to your web control account.
Or you need to use a ssh tunnel to the remote machine.

Remote access to a local web control for 8.3 is a bit dodgy to configure, and will not work with 8.4.

[calxalot]

You should not be running the client as root.
Please use the installer package and systemd service.

[trleith]

Thanks for the replies.

This works, sort of.

The most obvious problem it seems to ignore <cpus v='12'/> or <cpus v=12/> with or without the tick marks. It uses 31 of my 32 cores.
I don't understand something about allowed-origins -- I should think it could accept a CIDR mask like 192.168.0.0/24 instead of making me explicitly name my laptop's IP address. I didn't try using its DNS hostname (I register hostnames for DHCP assigned addresses). Why does it make me name a protocol (http or https)? Something else I don't think I tried was http://192.168.0.0/24.

What happed to the slot definitions?

It's great having a way to see the protein like the workstation clients.

Thanks again,
t

Anything exposed in web control is stored in client.db. For those things, config.xml is only relevant on first run.

There are no slots.

Please read the guide
https://foldingathome.org/v8-3-client-guide/

[calxalot]

You need to include port number in allowed origins if it is not the standard http/https port.

[calxalot]

A local web control is served by the client, so the allowed origin needs to include the host that is running the client.

Like I said. Dodgy.

Example origin
http://homeserver.local:7396/

PS don’t share your account token unless you want other people to join your account.

[calxalot]

The directory fah-web-control needs to be in the client data directory, which is its current working directory when it runs.

You honestly should not use the local web control. There is no need when you have the client linked to your account.

[trleith]

> Please read the guide

That is what I needed, thanks. I think the difference between "Without an Account" and "With an Account" is one thing that was throwing me.

> Anything exposed in web control is stored in client.db. For those things, config.xml is only relevant on first run.

That's not very Unix-y. Likely to cause support problems. FWIW.

I notice when https://beta.foldingathome.org/machines is open on Edge on my laptop, not the server runing fah-client, the browser becomes very slow with a jerky cursor. As soon as I close the tab, it all goes back to normal

It's folding away now, on 24/32 cores. After it finishes up this work unit tomorrow, I'll move the GPU from the old machine to the new machine and start in on NVIDIA .

[calxalot]

The url for 8.3 is v8-3.foldingathome.org
You can also use v8-4.foldingathome.org which is backwards compatible

The beta web control url is very old.
