Date: 2015jul1 Product: Boinc OS: Linux Keywods: SETI, SETI@Home Q. When I run BOINC Manager I get: Unable to connect to the core client How can I fix that? A. This worked for me... Install the package on RedHat/Fedora/CentOS:

dnf install boinc-manager

In a Gnome terminal window:

su (become root) cd ~boinc (change to boinc's home folder) boincmgr (run boinc manager)

Running apps as root isn't so great. But launching it from the Gnome menu didn't work. This assumes you want to run manager on the same machine as boinc-client. I did *not* have to open a hole in the firewall. You could also do:

su -c 'cd ~boinc; boincmgr'
