ChristianBeer has described the issue like following
The Client and Manager are communicating via TCP so there is always a
possibility that a firewall is restricting access to the port the
Client uses even on the loopback interface. It is most likely related
to a local change of the firewall or dns resolver update.
Biodoc has given 2 solutions for this issue:
First Solution:
- 1) open a terminal window
- 2) cd to your BOINC directory (I run the installation script in my
home directory so my BOINC folder is /home/mark/BOINC)
- 3) start boinc: ./boinc (this will run boinc w/o the GUI interface)
- 4) open another terminal window and cd to BOINC directory
- 5) start boincmgr: ./boincmgr (this will start the GUI interface)
It's kind of cumbersome but it works for me.
Second Solution:
Here's another option (longterm solution).
Say you want to manage your boinc projects on your linux box from another machine on your local network.
On the linux box:
- 1) stop boinc and open a terminal window.
- 2) cd to BOINC directory
- 3) gedit ./gui_rpc_auth.cfg (this file contains the password for
remote "control" of boinc)
- 4) the default password is insanely long so delete it and change it
to something easy to remember.
- 5) save the file and close gedit
- 6) find out the ip address of this machine by typing/running ifconfig
- 7) write down the ip address and consider changing you router
settings to fixed ip addresses. Otherwise, the next time your reboot
the machine it may grab a different ip address.
- 8) start boinc with this command: ./boinc --allow_remote_gui_rpc
- 9) go to another computer and start the boinc gui
- 10) go to the "advanced" menu and choose "select computer.."
- 11) type in ip address and password for your linux box and now you
should the boinc tasks/projects on the remote linux box.
- 12) Important (took me a while to figure this out): to go back to
your local machine, go the advanced menu and "select computer", then
type in localhost and the local password should pop-up automatically.
