... and push files to me?
Sorry, but this is impossible with BOINC

What you can do instead: Install a Linux-VM (or a WSL2 with Linux) on your Windows-Machine. Then you will increase your chances to get work (under Linux).

I have done this round about november last year and until now I've got more than 350 WUs to crunch.
Supporting BOINC, a great concept !

I've just done this with VirtualBox and had a right hassle. Apparently WSL2 is easier. Mind you most of my problems were not having a clue how to use Linux. It's 50 times more complicated than Windows. For example not having permission to edit cc_config in Boinc because the file on my machine for a program installed by me apparently doesn't belong to me! Screw that, I have it set to auto log in as root and life is so much easier. Contrary to what geeks say, this will not rip a hole in the space time continuum or make the police knock down your door in the middle of the night. It's your computer, you should be allowed to do what you like with it!

Oh and you have to install some 32 bit libraries or half the CPDN tasks fail.

Linux being based on Unix has carried on the same security practices which were designed for commercial rather than home use. Of course you are free to ignore them and do everything as root if you want and for a lot of users that is fine. I would not do this on a computer I used for accessing my on line banking but if it were a machine only used for crunching, then I don't see much of a problem. I wouldn't do it but I know my way around Linux well enough for these things not to be a big issue. Editing the files for instance, once read permissions are allowed, I can open the files with a text editor. Saving them requires me to put in my password. A useful prompt if like me you don't always save a backup in case you mess it up.

And by the way: For us Windows-Guys it is really difficult with starting on Linux, but meanwhile I like my Ubuntu 22.04.x clients (I had better stayed with Ubuntu 20.x, but now it is too late). I can manage most of the things like I'm used from windows and so this is okay

But since it's used at home a lot, there should be an easy way of turning that stuff off. It's quite a hassle to engage root.

Why not? I have full privileges on my Windows machine I use for banking. I'm not asking to reduce security from the outside, but to remove it from the keyboard right in front of it which only me or trusted people ever access.

but if it were a machine only used for crunching, then I don't see much of a problem. I wouldn't do it but I know my way around Linux well enough for these things not to be a big issue.

A useful prompt if like me you don't always save a backup in case you mess it up.
I wouldn't mind if it just asked for a password, but the default setup for Linux means when I try to edit cc_config.xml I cannot save it. It doesn't let me. I don't want to type stuff into the command line, I want to double click it, like any sensible OS, it opens in a text editor, I make the changes and save it!

Yes I was directed to those horrid nonsensical commands. Wow, Windows did away with that crap in the 90s. Linux is like using a DOS machine.

And by the way: For us Windows-Guys it is really difficult with starting on Linux, but meanwhile I like my Ubuntu 22.04.x clients (I had better stayed with Ubuntu 20.x, but now it is too late).
My Ubuntu 20 gave me updates, it never took me to 22. Oh, the auto update doesn't work, typical. Manually it offered me 22.

The threads and comments seem very excitable. I understand why my post got moved but took me ages to find it in the thread channels.
I do have Linux VMs for LHC and they appear stable so I can run windows and Linux binaries.
Nothing I've read tells me why I don't get any modules or files to work on anymore.
I have done as much as I can wrt preferences as far as I can see but nothing.
I have powerful modern gaming PC I rebuilt last summer and should be able to run even the most insane modules you come up with.
I look forward to somehow being able to contribute to CPDN again else LHC, Milkyway and Einstein will get my CPU hours contributions. Your choice......

You need to install BOINC on Linux in your VM. Then add cpdn to it. It will then show up as a separate computer on your account. When I looked just now you only had one windows machine attached to the project.

You should get en email telling you where it was moved to, with a link.

LHC have gone to the trouble of making it automated. CPDN have not (LHC is a very big establishment with lots of money, this is not). You have to install Linux yourself in a virtual machine. I did it with Virtualbox since I already had it, but it's quite a hassle. I've been told WSL2 is easier, but since most of my hassles were working out how to use Linux, I doubt there'd be much difference. Try it. If you get stuck ask in here, I've got it to work so I can help, so can many others.

I use Boinctasks already, since I have 8 Windows PCs. It's fairly easy to make that view the Linux "machine" too. Otherwise you can just use it seperately as though it was another computer (it'll be inside a window on your Windows machine). The Boinc in there doesn't know about the Boinc in Windows, so you'll have to manually change how many cores each one gets. CPDN work is sporadic, so when I get it, I turn my Windows one down to less cores (which is currently doing Rosetta).

Are there any BOINC projects that deal with cloning? Or bi-location? I have some spare cycles I could donate if that would help this issue.
We can already do it, but those crazy moralists won't let us.

You can get your pet dog duplicated though. Body only. It won't have the character traits or memories. I guess we need to work on that.

I thought it was introduced for banking, you know, important secure stuff?


Personally, I see climate research as rather more important than banking.

On a more serious note, CPDN and a number of other projects have experienced both hacking attempts and ddos attacks in the past. I doubt if you will find many people running websites now who would be happy to forgo the security offered by SSL.

Not what I meant. A hacker can steal your money. I don't really get too upset if someone steals my Boinc password.

And how does me connecting to CPDN with SSL stop a hacker hacking into CPDN? What does SSL do? It just proves each end is who they say they are. Anyone can sign up to CPDN, stealing my password doesn't allow a hacker into anything special. Perhaps your password would let them into something, but why secure the basic user passwords?

Don't buy Lithium batteries, Lead Acids are 7 times cheaper. The most economical are the 130Ah leisure batteries. You can also get some nice 5 or 7kW inverters.


The 48V/225Ah bank of Trojan T105-REs out back of my office says, "Yeah. I know." Though I'm planning to replace those at some point soon-ish with a LFP bank for a range of reasons, partly R&D related. The big inverters are a pain to live with, though. The idle draw on an inverter is proportional to peak rated output - my 2kVA inverter idles at about 30W DC, a 6kVA inverter I have idles around 100W DC. That's more than my entire office idle load in the winter. I've been in a purely off grid, solar powered office for 7 years now, and I've at least *some* clue as to what I'm doing.

In any case, plenty of zero carbon compute waiting for tasks. For values of "zero carbon" related to "If I have enough sun, the carbon cost of running an extra few kWh through my office on any given day is zero, as the infrastructure is here regardless of if it's fully utilized or not." I've put almost 16MWh through my main charge controller, plus probably another MWh or so through my morning panel controller.

Yeah, that makes sense - it's never actually stopping the task, from the task's point of view. Suspending a VM is even less disruptive than an S3 suspend/resume cycle, which doesn't seem to bother CPDN tasks in the slightest either.

The LHC VBs are launched by Boinc, not sure how I'd save their state.

Actually, I think VB does that for you. I've seen "saving state" in the screen I get when I tell windows to shut down or restart. So I'm not sure why I lose LHC tasks just by rebooting.

What would possess you to spend 7 times more than you have to?

You can always have many sizes and switch about. Grid tied ones are nice, or ones you can tie to each other with a link wire. Set something up to turn on the big one when the small one is approaching full load.

In any case, plenty of zero carbon compute waiting for tasks.
I subscribe to far too many projects. There's always something to do.

For values of "zero carbon" related to "If I have enough sun, the carbon cost of running an extra few kWh through my office on any given day is zero, as the infrastructure is here regardless of if it's fully utilized or not."

My Aunt thinks her electric car is zero carbon. I can't seem to convince her it's actually powered by gas fired power stations, since the wind farm electricity is already being used.

In my state a large proportion of electricity is generated by burning coal (even though coal is not mined in my state). A very large proportion of the electricity is produced by nuclear waste generation plants. One of these is about 50 miles from where I live and is of the same design, but older than, the nuclear reactors in Fukushima Japan that are contaminating the Pacific Ocean to this day and no end in sight.

Disposing of nuclear waste is much more difficult, dangerous, and expensive than disposing of the greenhouse gasses from coal burning. Also the carcinogenic other toxins produced by both coal burning and nuclear leakage continue to plague the planet and all living things on it. Perhaps cockroaches are relatively immune to radioactivity, but the rest of us are not.

We burn trees from Canada in the UK! They probably call that green because they can plant new trees....

Is your area likely to have a tsunami?

The use it instead of disposing of it.

The ocean and plantlife does that for us.

Alledgedly everything produces cancer. We can't do without everything.

Something often suggested by those who say nuclear power is the answer to global warming. None of them seem to be able to point to a design that anyone is prepared to build.

But not as quickly as we are producing it as numerous scientific papers have demonstrated.
