I have the issue of "Unable to connect to core client" that others have had in the past and their solutions are not working.

I do not have a firewall running.

The suggestion here has already been carried out by the install script:


Apparently the BOINC client is running but this is not reflected in the output of nmap localhost.

Nothing works.

Running Ubuntu 14.04.3 LTS, BOINC version is 7.2.42 i686-pc-linux-gnu.

  • Have you solved your issue? – user123456 Oct 8 '16 at 18:16
  • I uninstalled BOINC and have been using F@H since then. I'll let you know what happens if I attempt to test it now. – readyready15728 Oct 10 '16 at 1:33
  • Since I did this uninstall, Ubuntu has a package prepared for BOINC, which is effective. I will accept your answer though I have no way to verify this is my only option anymore. – readyready15728 Oct 10 '16 at 1:37

Use the terminal:

sudo boinc --dir /var/lib/boinc-client

If the project is not attached yet, run:

sudo boinc --dir /var/lib/boinc-client --attach_project [URL] [KEY]

Where [URL] can be found in the project list and [KEY] is given by logging in in project site or by running after registration:

sudo boinc --daemon
sudo boinccmd --lookup_account [URL] [MAIL] [PASSWORD]

For instance, formilkyway@home, I run BOINC with:

sudo boinc --dir /var/lib/boinc-client http://milkyway.cs.rpi.edu/milkyway 6c2b64e6238a1223e3a4f8db56eabb3d

where my key is obtained using:

sudo boinc --daemon
sudo boinccmd --lookup_account http://milkyway.cs.rpi.edu/milkyway/ mymail@address.com mypassword

mymail@adress.com may be replaced by the username for certain project (including the worldcommunitygrid )
