Ok, I decided to try Ubuntu Linux distro again. Basically because all I want to do with it is run a CNC controller and Boinic. Those are it\'s ONLY two purposes and uses\'.

However, when I installed Boinic it cannot connect to localhost computer.
So what is the deal?
This is one of many reasons why I honestly perfer MS systems but as I said these machines that I will be using will ONLY be used for CNC and Boinic simply because I want them to always be doing something.

I go to file, and the only option is disconnect.

I\'m not a Linux person, but if it was Windows, it would mean that the gui, (boincmgr.exe, the visible part), can\'t connect to the worker daemon, (boinc.exe, the invisible part).

A reboot is the quickest way to try again, or in the menu, click on Select Computer, (which I think is now in menu/Advanced), then click OK with the 2 fields left blank.

The 2 parts of BOINC talk to each other via ports, and if this is blocked, then you get the \"cannot connect\" message.
In Windows, this can be because:
1) another process, often a Windows program, got to the port first.
2) the firewall is blocking the needed ports.

Ports needed by BOINC:
BOINC.exe needs 31416 and 80 and 443 opened
BOINCmgr.exe needs 31416 opened
BOINC.scr needs 31416 opened

You have to install boinc-client and Boincmgr in Ubuntu (boinc is the universe or multiverse repositaries, I dont remember exactly):
$ sudo apt-get install boinc-client boinc-manager
(check that boinc-client is installed and the service running before checking the firewall and the ports)
You can restart, stop, start, view status of the service by:
sudo /etc/init.d/boinc_client [restart, stop, start, status, force-reload]
