61) Message boards : BOINC Manager : Boinc manager stopped loading (Message 77670)
Posted 29 Apr 2017 by ChristianB
Post:
The log you posted is the client startup log and you are starting it in your home directory instead of the BOINC data directory. If you want to start the manager you need to use the menu shortcut which starts the manager in the correct directory. Alternatively you can try to start "boincmgr" on the commandline not "boinc".

Gist from the github issue: The email addresses of the two accounts are different. One comes from BOINC wide teams and one was created manually later.

My advice is to change the email of the BWT account to one that is accessible and there is no need to create a separate account on new projects that have BWTs already imported in the future.

Changing existing accounts with the old email address on projects is difficult since Adrian has no way to login to that account. Ownership of the team (at least on the two mentioned projects) should be transfered to an account that is accessible or someone else could take ownership of the team (since the current founder cannot deny the transfer request).

There was some discussion in the past and funding for research that tried to find the "sweetspot" for modern CPUs where they are most energy efficient. This involved a custom Windows driver that acted as a kernel module to actively influence power modes which is normally not possible for userland processes. I remember that they tested a handful of CPUs and were able to find the power mode where the CPU is energy efficient but without the driver and user intervention it was not possible to replicate this. So in general, nowadays BOINC is causing a higher electricity bill because CPUs are getting better and better in regards to energy saving but programs do not have the ability to influence that through the operating system.

Automatically adding projects can be done again in multiple ways. If you don't want to use a static list you could use an account manager or if you have a static list you can provide an initialization file.

HAL9000: with this process you should also run into the one host-CPID for all cloned hosts issue as the host-CPID is generated at first startup and is based on the first available MAC. If you clone the VM after this was set all clones will use the same host-CPID. The Client can generate a new host-CPID if it detects a clash but that will only work if the first available MAC on the cloned VM changed after cloning from the original VM.

This is not easily explained as there are multiple posibilities depending on your specific setup. I would suggest to schedule a phone or skype call to talk about this in person (possibly in German too).

The meaning is that file_deleter needs to have set the file_delete_state for all results and all workunits to done. file_deleter should ignore remote files and set the status to done. If that is not working check the file_deleter logfile why it is not setting the status.
67) Message boards : BOINC Manager : New ResourceShare values are not "read" by some hosts (Message 77293)
Posted 11 Apr 2017 by ChristianB
Post:
The problem with issues like that is that they are hard to reproduce. If it is only happening on some hosts but not on others I can't reproduce this on my end. What I could do if I find the time is to check where the value the Manager show to the user comes from. Normally this should come directly from the project specific preferences XML. Do you still have hosts that show this discrepancy or di you clean them all?
68) Message boards : BOINC client : Feature suggestion: staggered start of VM jobs on slow storage (Message 77123)
Posted 3 Apr 2017 by ChristianB
Post:
This is enabled by default since vboxwrapper 26077 and is called random_checkpoint_factor. Apparently this does not apply at startup although I thought that it did in the past. It should be easy to build in a sleep command with this random offset before the I/O intensive part begins. This would be a Vbox only change that can be deployed by VM projects immediately.

The issue SekeRob is refering to (https://github.com/BOINC/boinc/issues/1293) is trying to fix the problem for all applications by a change in the client which will only be available in a future Client version if someone implements it.

This was already implemented into vboxwrapper. It might need to be adjusted to todays computers where you want to run >4 VMs at the same time.

No, there is no way to turn this message of on the Client besides changing the source code and deactivating the master_url check for all projects.

Did you already check the pogs forums? There is a thread that says they changed from http to https and back to http. https://pogs.theskynet.org/pogs/forum_thread.php?id=785

So you need to make sure you attached via http (no s) in order to get rid of this message.

Post:
On further thought, it's trivially easy to remove even read access for all but you and members of your group after you've got BOINC running and that would make sure that other users of that box, if any, wouldn't be able to access it.

That would be my safer way too. Allow group read access to gui_rpc_auth.cfg and add yourself to the boinc group. That should make it possible for any member of the group to control the client as long as the manager is started within the client directory. Either cd into this before starting the manager or use the commandline argument -d and specify the /var/lib directory.

Fedora is the only distribution (I know of) that by default sets a password. On Debian where the file is also protected in a similar way they don't set a password so users don't experience this problem until they set a password but then they usually already added themself to the boinc group.

Post:
Access to the content of gui_rpc_auth.cfg allows anyone to control your locally installed BOINC client. Anyone with read access to client_state.xml can read your authenticator and login with your account at your projects. Securing the client directory and presetting a password was done intentionally by the Fedora packager. This error report comes up from time to time and it's not something BOINC has control over directly.

I just want to add that Fedora in particular sets up the BOINC Client and Manager in a particular way to make it secure. The instructions you linked to undo this. Just so any future reader is aware of that.

Debian offers packages 'boinc-client' and 'boinc-manager' which come pre compiled using the correct versions of the dependencies. Please use those if you do not need special development features.
77) Message boards : Questions and problems : ** Solved ** Retrieving donations made to each project, via code/XML files? (Message 76504)
Posted 17 Mar 2017 by ChristianB
Post:
The information if a user has donated to a project is already publicly available and indicated using a small icon on the user page and in the forums. Example: http://www.rechenkraft.net/yoyo//show_user.php?userid=19528
This information is just not exported into the stats export or via any other webRPC. But it can be added if there is a demand for it. Please open a github issue requesting this feature stating why you want to have it. This does not mean it will be immediately done and when it is done it will not be immediately available at all projects.

There is another way that involves screen scraping this information which is usually not very nice because it puts additional load on the project servers if not done right.

Post:
There is a lockfile generated in your home directory that is sometimes not deleted when the Manager is closed. So next time you can't start the Manager check in your home directory if there is a file called "BOINC Manager-{username}" and delete it. That should fix the issue. This is a known problem on Linux.

Dude, I was just coming here to post my success story. You stole my thunder! :)

Thanks!!!

I used wireshark to look for DNS traffic, saw that the BOINC client looked for srv3.bakerlab.org. Used the suggested manual IP resolution site, and got its IP.

I would have posted the list earlier but I don't run Rosetta. The easiest way to compile the list is to look for bakerlab.org in the local client_state.xml file of a Client that is attached to Rosetta. No need for capturing packets although that worked too.

I have hacked the /etc/passwd file (on Windows) as such:

You mean /etc/hosts. Here is the rest as found on https://twitter.com/chenshaoju/status/839773321759621120

128.95.160.140		boinc.bakerlab.org
