NAME

6       boinc - The BOINC client program.
7

SYNOPSIS

9       boinc [options]
10

DESCRIPTION

12       The  BOINC  "client",  boinc, is the heart of BOINC.  It controls which
13       project applications are run on your computer, downloading "Tasks"  and
14       uploading  the  resulting  files from completed tasks. boinc is usually
15       run in the background, ideally as a daemon. It can then  be  controlled
16       either  by a graphical tool called the BOINC Manager, boincmgr(1), or a
17       command-line tool called boinccmd(1),  by  means  of  Remote  Procedure
18       Calls (RPCs) over port 31416.
19
20       The  BOINC client can be controlled by command-line options, configura‐
21       tion files, and environment variables.  Standard  usage  is  simply  to
22       start the client running in the background.
23

OPTIONS

25       These  command-line  options for boinc can be used to control how BOINC
26       is started. Once the client has started, you should use a separate pro‐
27       gram,  (boincmgr(1) or boinccmd(1)) which communicates with it by means
28       of Remote Procedure Calls (RPCs).

85              Omits creation of a socket as required for the remote control of
86              the client. Consequently the client cannot be controlled by  ex‐
87              ternal  tools  like  GUIs (boincmgr etc.) or the console command
88              tool (boinccmd).

96
97       --exit_after_app_start N
98              Exit N seconds after an app starts. Useful to look at the  files
99              in the slot directory.
100
101       --exit_after_finish
102              Exit  right  after finishing a task. Useful to look at the files

ACCESS CONTROL FOR GUI RPC

159       By default the client accepts GUI RPC connections only from programs on
160       the  same  host, which means that any user on this host can control the
161       client.
