## TL;DR
Files are located in `/var/lib/boinc` by default.<br/>
Some distribution (debian and derivate) use `/etc/boinc-client` for configuration files instead, and create links to them in the default location.

The resource share property can be set anywhere from 0 to 1000 for each project, with 0 meaning it will not get any work from that project unless every other project you run is out of work.

Local control RPCs are authenticated using the GUI RPC password. This password is located in the `gui_rpc_auth.cfg`
configuration file, as the single first line, with a max length of 255 characters.
A password is **required** from version FIXME, and is automatically generated if the file is not found or it is empty.
Resource share is used to help BOINC determine which projects to prioritize; the larger the number, the more it will prioritize work from that project over the other projects.<br/>
This value does **not** determine anything about how much of your CPU, GPU, etc. are used. If you want to do that, change the relative settings.<br/>
The number for resource share can be set anywhere from `0` to `1000` for each project. Setting a project's resource share to zero means it will **not** get any work from that project **unless** every other project you run is out of work.

### Remote management
All remote RPCs (both status and control) are authenticated using the GUI RPC password.
Quick, dirty solution: use the `--allow_remote_gui_rpc` option when starting the client.<br/>
This will make the BOINC client accept connections from **any** host (subject to password authentication) even if the client's configuration files are set otherwise.
This will make the BOINC client accept connections from **any** host (subject to password authentication) even if the
client's configuration files are set otherwise.
Better solution:
1. add the `<allow_remote_gui_rpc>1</allow_remote_gui_rpc>` **option** to the `cc_config.xml` file in the BOINC data directory
1. restart the service to make the above change effective
1. check port 31416 (or the one configured for use) is reachable from other hosts
1. specify a set of allowed hosts creating the `remote_hosts.cfg` file in the BOINC data directory; its entries must be DNS host names or IP addresses, and must be one per line
