Basic installation

Installs BOINC Client as a daemon and puts a BOINC Manager icon on the "Start Menu" if you have a GUI Desktop installed. Open a terminal and enter the following command:

After the installation is finished, you can enter either sudo rc-update add boinc default or sudo systemctl enable boinc-client to have your system auto-start the boinc-client daemon at boot time. (See Stop or start BOINC daemon after boot page for helpful daemon managing commands)

What the installer does

  1. Creates the daemon script at /etc/init.d/boinc
  2. Creates the daemon script configuration file at /etc/conf.d/boinc.
  3. Puts the BOINC binaries (boinc_client, boinccmd and boincmgr) in /usr/bin/boinc
  4. Creates /var/lib/boinc/ for BOINC data files and the slots and projects directories.
  5. Names the daemon boinc
  6. Creates a user named boinc. For security, boinc owns the BOINC data directory (/var/lib/boinc/) and all the data files and sub-directories it creates in the data directory.

Verify the installation

  1. Start the daemon with /etc/init.d/boinc start
  2. Open a terminal and enter ps aux | grep boinc to print a partial list of running processes. You should see boinc_client in that list, if not then something went wrong in the steps above.

Set up your accounts

To use the GUI to set up your accounts and monitor progress:

  1. Start "boincmgr" on the command line or select Applications -> System Tools -> Boinc Manager from the GNOME menu.
  2. Select Advanced -> Select computer... from the Boinc Manager menu.
  3. Put "localhost" in for "Host name" and the contents of /var/lib/boinc/gui_rpc_auth.cfg for "Password" and hit "OK".

To make the GUI passwordless instead, do "echo > /var/lib/boinc/gui_rpc_auth.cfg" (which replaces the contents of the file with a newline) and then restart boinc-client (with e.g. "/etc/init.d/boinc restart").

Alternatively, you can use the command-line interface to set up your accounts. See "man boinc_cmd" for instructions.

Optional setup hints

''For more information about configuring BOINC in Linux, see Linux file permissions''

If you do only the basic installation as described above, BOINC manager will not be able to automatically connect to the client. To connect the client you will be required to give the GUI RPC password every time you start BOINC manager. That is not a bug, it is a security feature to prevent other users from using the manager to manipulate the client, changing your projects, etc. Another inconvenience is that boinc (the user named boinc) owns /var/lib/boinc/ and all the files and directories in it so you will not be able to edit those files from your regular user account unless you add your username to the boinc group and adjust some permissions as follows, substituting your username for :

  1. As root, open /etc/group in a text editor.
  2. Look for the line starting with boinc:x::
  3. Edit the line to look like boinc:x:: ( will be a number, do not change it)
  4. Save the file and close the editor. All the above can be done by: (sudo) gpasswd -a boinc
  5. Open a terminal as root and enter the following commands, substitude your username for : ln -s /var/lib/boinc/gui_rpc_auth.cfg /home//gui_rpc_auth.cfg chown boinc:boinc /home//gui_rpc_auth.cfg chown boinc:boinc /var/lib/boinc/gui_rpc_auth.cfg chmod -R g+r /var/lib/boinc

Uninstallation

As root, in a terminal, enter emerge -C sci-misc/boinc

Troubleshooting

In case you get SSL connection error, this can be solved by re-emerging curl with gnutls USE flag disabled: echo "net-misc/curl -gnutls" >> /etc/portage/package.use emerge -1 net-misc/curl
