Client Setup Logic for 6.0 Clients

Starting with the 6.0 client release the service-mode install type will be the only supported install type. We expect to receive the following benefits:

• Simplified installation experience.
• Increased security.
• Increased stability for project applications.
• Graphics available for all users, instead of just the first user to login.

NOTE: Windows9x will continue to be treated as a single-user install.

User Accounts

Two user accounts will be created, one to execute boinc.exe, and one that boinc.exe can use to launch science applications.

NOTE: Including the computer name avoids name collisions when BOINC is installed on domain controllers.

Users:

boinc_<ComputerName>
boinc_project_<ComputerName>

Both boinc_<ComputerName> and boinc_project_<ComputerName> should be setup so that their passwords never expire.

A file should be dropped in the BOINC data directory called client_init.xml which contains the username and base64 encoded password for boinc_project_<ComputerName>. The first time the client starts up after install it should read the file and store an encrypted form of the data in the state file using CryptProtectData/CryptUnprotectData. After reading in the client_init.xml file it should be deleted.

Groups:

boinc_administrators
boinc_project

Each group will contain the following members:

boinc_administrators	Administrator <Installing User> boinc_<ComputerName>
boinc_project	boinc_project_<ComputerName>
Guests	boinc_project_<ComputerName>

Data Directory

All data, configuration files, and logs will be moved to the following default location:

Vista:
C:\Users\All Users\BOINC

2000/XP:
C:\Documents and Settings\All Users\Application Data\BOINC

Under BOINC there will be a 'projects' and 'slots' directory.

Directories will have the following permissions:

BOINC	SYSTEM (Full Control) Administrators (Full Control) boinc_administrators (Modify, Read & Execute, List Folder Contents, Read, Write) boinc_projects (Deny All)
BOINC\projects	SYSTEM (Full Control) Administrators (Full Control) boinc_administrators (Modify, Read & Execute, List Folder Contents, Read, Write) boinc_projects (Modify, Read & Execute, List Folder Contents, Read, Write)
BOINC\slots	SYSTEM (Full Control) Administrators (Full Control) boinc_administrators (Modify, Read & Execute, List Folder Contents, Read, Write) boinc_projects (Modify, Read & Execute, List Folder Contents, Read, Write)

Notes: What to do if an organization has disabled the 'Bypass Traverse Checking' user right for Everyone? See ​http://support.microsoft.com/kb/823659 for more details.

Executables Directory

Same location as the previous releases.

C:\Program Files\BOINC

Directory will have the following permissions:

BOINC

SYSTEM (Full Control) Administrators (Full Control) boinc_administrators (Modify, Read & Execute, List Folder Contents, Read, Write) boinc_projects (Deny All)

Additional Notes

Each time an installation occurs, both of the account passwords should be reset and a new randomly generated password should be used.
