In my opinion the problem is not the 32 hex char, I have changed the permission of the gui_rpc_auth.cfg file in the BOINC (data) directory (chmod)

-rw-r--r-- 1 boinc boinc 33 apr 28 22:37 gui_rpc_auth.cfg

and log file:

-rw-r--r-- 1 boinc boinc 0 apr 29 00:04 boincerr.log
-rw-r--r-- 1 boinc boinc 86517 apr 29 00:30 boinc.log

And now it works. But I have made a lot of change that I have reversed to the original. I'm not sure why it works now.

All right, with that out of the way, try to set a password in the gui_rpc_auth.cfg file in the BOINC (data) directory. By default it's got a random 32 character hexadecimal password in it, but that may not work well.


In the log file(/var/log/boinc.log):

28-Apr-2016 20:09:46 [---] Data directory: /var/lib/boinc

In /var/lib/boinc there is the file gui_rpc_auth.cfg
I have inserted a random password like casetta.

When you do set your own password, remove the 32 char word and in its place put your password. Don't add an enter at the end though.

You can also try to start the client with boinc --gui_rpc_port 31416 to specifically tell BOINC to use that port and then start BOINC Manager with the same attribute, boincmgr --gui_rpc_port 31416

You do need to run these commands from the directory the client and manager are in. I am not sure if the name of BOINC Manager's binary is boinmgr.
And of course, if you suspect it's something about the port number, you can try to give them a different number, e.g. boinc --gui_rpc_port 62555 and boincmgr --gui_rpc_port 62555

Did you start the BOINC client before you started BOINC Manager? Unlike with Windows and Mac OS X, starting BOINC Manager under Linux does not start the client. It has to be started separately.


Tanx a lot for the reply. I have noted that my service wizard shows a new service (I have sistemd) named boinc-client that is running and is started on boot. (But I have changed the default.) So boinc-client is start automatically after the boot. I have never started the client but it is running:

boinc 1709 0.0 0.0 12576 2604 ? SNs 20:09 0:00 /bin/bash /usr/bin/boinc --dir /var/lib/boinc
boinc 1715 0.3 0.2 90060 8600 ? SNl 20:09 0:01 /usr/bin/boinc_client --allow_multiple_clients --dir /var/lib/boinc

Hi,
I have Installed Boinc via standard Mageia Repository and then I have start Boinc Manager via Start menu.
Manager shows:
Retrieving current status
and then:
Unable to connect to the core client

I have reboot and the error don't change. I have read a problem about firewall and I have put in my firewall the port:
31416/tcp

The command:
# lsof -i :31416

My Internet connection is NATed

Any solution?
