Hi,

Now, I use OpenSuse and Boinc client show me "no internet connection". I saw readme file which describing popular bug #707 but it could not help me much.
I tried search on this forum(and internet too) any information about my problem, but nothing useful.

Any idea? Solutions?

Before it I used same client on Ubuntu and Mint, and had no problems.

Do you have firewall enabled and if you do have you permitted BOINC client (program name 'boinc') to connect to Internet?

I tried enable/disable firewall but result without changes. Also I tried reconfigure boinc client - Nothing.

Earlier you said you searched for information. I assume you used the host in question to do it. That is, the host really has a working Internet connection?

Does your Internet connection require using proxy?
It's really client saying it can't connect to Internet, not Manager saying it can't connect to client?
Could you enable file_xfer_debug and http_debug flags and post log messages when the client tries to connect to project and Google.
What version of openSUSE is this anyway?

Thank you for reply!

Yes, it has internet connection.
No any proxy. At my work I use 4 PC(windows)via proxy without any problem.
Client or Manager? I doesn't understand the differs, but in the BOINC window (bottom-right part) show "Disconnected". In the Simple view - "Unable to connect to the core client"
Version "openSUSE Leap 42.1 (x86_64)"
In Log tab no records (Advanced-Event Log). Nothing to change whet I press Ctrl+Shift+E or Ctrl+Shift+F. And I can't find file "cc_config.xml" on my disk to enable log.

Client or Manager? I doesn't understand the differs

There are 2 parts to BOINC:
1) The "client", which is a closed room "somewhere", which may or may not be full of workers.
(Full = "client running", empty = "client not running".

2) The "manager", which is a large video screen in the room where your are. It displays what is going on in the room with the workers.

in the BOINC window (bottom-right part) show "Disconnected"

Either the video camera / display screen is broken / turned off.

In other words, the Manager isn't connected to the Client, so the Manager that you're looking at can't tell what is happening. It could be that the client isn't running.

What you have to do, is:
1) Find out which of the 2 above is the problem, and then
2) Find out what is stopping the connection, or Start the client, as appropriate.

The 1st part: something is using / blocking that port.
For the 2nd part, run the file that starts the client. Not sure what or where that is for your set up.

Ah, that helps. We have been busy fixing a problem you didn't have :/

I think adding your account to boinc group should be enough.

If you want to know about client and Manager check How BOINC works which explains all the parts that make up BOINC.

Thank you for detailed explanation.
Actually, when run GUI and it showing me "Disconnected"(in advanced GUI mode). And I have no information how I can see working process of boinc client without GUI.
Also I tried to switch off all firewall and start/stop the boinc process in process manager.
And I can't imaging where I can find/change port for boinc?

Sorry, but I'm just volunteer who want to share computational power of my PC.

Thank you for link it was useful for understanding the process.
I cant add any project; when I try it nothing to happens.
But if I try it couple of time it shows "The BOINC client has exited unexpectedly 3 times the last 2 minutes..."

Installing boinc-client package creates an account named 'boinc' and a group named 'boinc' on your computer. I meant, add your openSUSE user account to the 'boinc' group. The system should have some user account GUI configuring tool to do that.

Alternatively, if you are the only one using the computer or you don't mind others controlling BOINC you could just unset the GUI RPC password. That is done by opening /var/lib/boinc/gui_rpc_auth.cfg file with an editor and removing all content from it. The file really needs to be entirely empty, that is, file size is zero. You'll need to restart BOINC client after that (rebooting works).

I unset password but nothing.
I found something, any changes in "Computing preference" after "ok" not saved.
My be problem in it?

openSUSE package has had problems with getting Manager to connect to client. Looking at their package page it looks like the problems have been fixed but maybe the fixes didn't make it to the version you have.

Try File -> Select computer and in Host name put 127.0.0.1 and in Password put the contents of gui_rpc_auth.cfg.

Wonderful! it work!
Thank you! Thank you! Thank you!

But, one question is appear: how make it automatic?

You can edit the menu item for Manager.

If you are using KDE right click Manager menu item and select Edit application. In Application tab change Command to /usr/bin/boinc-gui and set Work path to /var/lib/boinc .

(If you use file browser to select the command notice that only boinc-gui is the real thing and the rest are buggy wrapper or links to the buggy wrapper.)

If that doesn't work then change Command to "/usr/bin/boinc-gui -n 127.0.0.1 -p <password>" replacing <password> with the contents of gui_rpc_auth.cfg. If not using password then remove "-p <password>".
