I use Boinc since years with different versions of Linux. Actual I use Linux Mint Version 15 (which is based on Ubuntu), which I installed in 09/13. I use the boinc-packages in version 7.0.27 from ubuntu and boinc runs at least until 10/27/13 normal - at this date the last result is transferred to World Community Grid.

Shortly after this date something happpens which prevents boinc from working, but I notice the problem in the last days after my vacation.

Now I see with

ps -A | grep boinc

a instance of boinc running. Also

sudo /etc/init.d/boinc-client status

says:

 * Status of BOINC core client: running
 * Scheduling of BOINC core client: 1691
pid 1691's current scheduling policy: SCHED_OTHER
pid 1691's current scheduling priority: 0

But no results are transferred and in top (list of processes) the processes, which are normally started from boinc are not listed.

Addional, when I start the boinc-manager, a messagebox is displayed, that communication with the client is done - but this messagebox stay until I close the boinc-manager.

When I use boinccmd with

boinccmd --get_state

I get

Error -102: read() failed

I use this http://wiki.ubuntuusers.de/BOINC to install addional the last version boinc_7.2.33_x86_64-pc-linux-gnu.sh from berkeley-boinc, but get the same problems.

I look in the history of apt-updates, but don't find something I can relate to the problem with boinc. And I cannot remember to have changed something end of october which can cause the problems.

All directories

/var/lib/boinc-client (data)
/etc/boinc-client (client from ubuntu-package)
/opt/Boinc (new client)

are owned by user and group boinc.

Can please give somebody a hint, how I can solve the problem?

The way I start / stop boinc on my ubuntu with repo client is [when needing to do this outside of the auto-start after a boot cycle]:

sudo service boinc-client start
sudo service boinc-client stop
sudo service boinc-client restart

In your case, it reads like the daemon is not running which you can kick with the above commands.

The .sh package installs differently to the repo kit [I don't use the .sh versions].

@SekeRob2, for me it looks like the boinc-daemon is running, but boinc simple don't work.

But I try your commands:

matthias@Midgard-Mint15SSD:~ > sudo service boinc-client stop

After that I try again to get a status:

matthias@Midgard-Mint15SSD:~ > sudo /opt/Boinc/boinccmd --get_state
Authorization failure: -102
[1]matthias@Midgard-Mint15SSD:~ > 

Has someone an idea, who to get more information about the running boinc without using the boinccmd or the boinc-manager?

Matthias

I find in /var/lib/boinc-client/stderrdae.txt many of this lines:

Unrecognized XML tag '<data_dir>' in LOG_FLAGS::parse; skipping

I don't know, if this causes the problems, but I found a temporary solution:
I stop the boinc-daemon and start boinc in the data directory without gui:

matthias@Midgard-Mint15SSD:~ > sudo service boinc-client stop
 * Stopping BOINC core client: boinc                                                                                                                                                                                  ... waiting ...........................................................                                                                                                                                      [ OK ]
matthias@Midgard-Mint15SSD:~ > cd /var/lib/boinc-client/
matthias@Midgard-Mint15SSD:/var/lib/boinc-client > sudo /opt/Boinc/boinc --no_gui_rpc

On this way boinc is working normal and tasks started from boinc are seen in the process-list.

I still prefer the boinc-daemon because this runs without separete start. But until I find a solution, I use this workaround.
