I got it going! I swapped over the M.2 SSD to the main M.2 slot, this freeing up a lane for the 2nd video card.

Both cards are crunching now so all good.

Hi

I have 2 video cards installed in my PC running Linux Mint 21.2

First card is a RTX3060Ti and the 2nd card is a RTX3060, so similar but a little bit different

BOINC recognises the first video card, but not the 2nd. How can I get two video cards crunching?

I added
<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

in /var/lib/boinc/cc_config.xml

But still no go. Can anyone offer any help?

Yes, these work. I will use the boinc-client script in /etc/init.d to control Boinc in the future.

Now, I have the problem of boincmgr not recognising the password in /etc/boinc-client/gui_rpc_auth.cfg

Whenever I boot up, boincmgr complains that it can't connect and says to reinstall.

I have to manually go to "Select Computer" and type in "localhost", delete the old password hash (where is this stored?) and add my own password. Boincmgr then connects to running client.

How do I stop boincmgr from reading the old password?

Boinc Manager is open. Projects and tasks displayed.

I kill all the WUs with "boinccmd --quit"

Then to restart I type "/usr/bin/boinc"
And get an error:
15-Jul-2021 19:15:23 Another instance of BOINC is running.


But didn't I just kill all the tasks before?

I start BOINC Manager through the Startup Applications app by running "/usr/bin/boincmgr" and with a start delay of 3 seconds.

Yes, I too run boinc as a service. I was just trying to use the command line to stop/start crunching when needed (like during an update).

Hi all,
Running Linux Mint 20.2.

I'm trying to write a couple of simple scripts in Linux to start/stop Boinc.
For stopping I have:

#!/bin/sh
boinccmd --quit


This kills all the WUs and leaves boincmgr open.

How do I now restart Boinc, with it running my previous project and WUs?

I have boincmgr starting up at boot with a 3 second delay. To do this I added the command "/usr/bin/boincmgr" to my Startup Applications.

When I now reboot, boincmgr opens, but is disconnected from the client - ie, no WUs are running.

Best to use the BOINC Manager to directly add a project through the Add Projects function in the Tools menu than trying to add a project directly through the website.
Your problem is very common with a lot of projects invoking a ReCaptcha barrier and the solution to Join a project through the Manager is the easiest solution.

Thanks for that. I managed to join this way.

This is the error message I was getting:

Hi,

When I go to the Amicable Numbers home page, and click on "Join", I enter my details and then tick the reCAPTCHA box. Everything seems to go well but I get the error message that I didn't complete the reCAPTCHA test!

Anyone else had this problem?

Not sure if this is the correct sub-forum, but here I am.

How can one find out the absolute first date they started crunching? Is there anything in BOINCstats or similar? I think I started off crunching SETI (like most people I guess) but am unsure.

The other, more permanent, way of fixing this is to add the owner to the boinc security group:

sudo usermod -a -G boinc ownername
And reboot


A cautionary tale, never try to perform updates from memory when your memory is as bad as mine.

I’ve just spent an interesting hour or so recovering my system having entered the above command and missing out the -a.

So instead of appending Boinc to the list of groups my user was a member of it replaced that list with just Boinc. The sole user on the machine was therefore no longer admin and had no sudo permissions.

It turned out that the root user is disabled by default in Ubuntu so I had no way to correct the problem.

I tried booting into a live session from usb but the system is too clever for that, it still would not give me access to system files.

I eventually managed to get into recovery mode once I worked out that the grub access key has changed from space to esc since last I used it. From there I checked the sudoers file thinking to add myself to the list but that was identical to my working system. Then I looked into the groups file and that’s where the changes had been made. It turns out that they don’t hold a list of groups you are part of and append new entries, it works the other way round and the entry for each group has a list of all subsidiary groups so I had to add my user to half a dozen entries (guided by the groups file on the working system).

I now know a lot more about the inner workings of group permissions but I’ll never make that mistake again - until the next time my memory goes awol :-)


Ouch. That's why I also copy and paste, then amend. Not totally foolproof but it saves me relying on my memory.

All good. A friend from the BOINC@AUSTRALIA forum pointed me in the right direction...

Open "File|Select Computer". Enter localhost and password from gui_rpc_auth.cfg file in /etc/boinc-client. All good! I can see my tasks again!

Hi
Recently joined QuChemPedIA project to help my team in a crunching challenge.

My PC fits the criteria - Linux Mint 20.1 and BOINC 7.16.16 from a PPA - BUT I have now discovered that the PPA version 7.16.16 produces dud results!

So to fix I removed the old version. Removed the PPA from my sources list. Installed new version from the apt repository (7.16.6)

ALL is well, "top" command shows 16 boinc commands crunching away at 100% CPU. BUT when I start BOINC Manager - no tasks/projects are shown.

Can anyone help?

You guys REALLY need to update the Linux x64 shell install file, and even the 32-bit version. It's getting kinda embarrassing. People that want to crunch on Linux have to go their software repository instead of downloading the latest version here.

A disclaimer of "This may not be the latest version" doesn't cut it in 2020.

Hi,

You've probably heard this before, but are updated versions coming for BOINC for Linux on the Download page?

I've installed BOINC on my PC (running Linux Mint 19.2) from the Software Manager and even that is version 7.9.3. I removed BOINC Manager and am using boinctui as I found the GUI manager to be buggy, as in not always connecting on bootup.

Thanks!
