How to Boinc on Linux (Debian)

At first:

aptitude install boinc-client boinc-manager

Then you have to create password for localhost, so open file and write your password on it.:

vim /etc/boinc-client/gui_rpc_auth.cfg

Restart client:

/etc/init.d/boinc-client restart

Next we want to attach to some Boinc project.

Find out your account key:

boinc_cmd --host localhost --passwd your_localhost_password --lookup_account http://einstein.phys.uwm.edu/ account_name account_password

Connect to project with your account key:

boinc_cmd --host localhost --passwd your_localhost_password --project_attach http://einstein.phys.uwm.edu/ your_account_key

Check Boinc state:

boinc_cmd --host localhost --passwd your_localhost_password --get_state

P.S.
Boinc client and his tasks usually running with nice 19.
