BoincTasks Js Find computers

The password file

The BOINC Client uses a password that is stored in a text file called gui_rpc_auth.cfg.
The file contains to password on the first line, nothing else.

File location:

Linux: probably /var/lib/boinc-client
Windows: probably C:\ProgramData\BOINC
Mac:  /Library/Application Support/BOINC Data

The remote access file

Another file controls the IP addresses that are allowed to connect to BOINC client.
This text file is called remote_hosts.cfg. Every line may contain an IP address.

For changes to have effect

Changing the files above has no effect, you MUST restart the BOINC client on every computer you make changes.

Linux: probably in terminal:
sudo /etc/init.d/boinc-client restart

Windows in command prompt:
“C:\Program Files\BOINC\ boinccmd –quit
“C:\Program Files\BOINC\boinc.exe” –detach_console

Otherwise restarting the computer may be simpler.
