1. What does CUPS do?
computer hostname - working directory - user account
Common UNIX Printing System (CUPS) manages all printing and faxing for the system.
Access is based on the local filesystem. They'll start in their home folder but can traverse anywhere they have permission to do so.
Standard - Admin - Guest - Sharing-Only - Root
2. What are five common directory services and authentication services troubleshooting techniques?
Access is based on the local filesystem. They'll start in their home folder but can traverse anywhere they have permission to do so.
1.) Try another account 2.) Reset the account password 3.) Verify directory service connectivity 4) Verify kerberos authentication & config 5.) Check directory service log files
HFS+ (Mac OS X Extended Journaled - Mac OS X Extended Case Sensitive Journaled - Mac OS X Extended) - HFS - UFS - FAT32 - NTFS - UDF
Prevents users from using the reset password utility on the os x install dvd because they cannot boot from it.

It does a 7-pass erase.
Screen sharing - remote login - remote management - remote apple events - and Xgrid sharing
Hold down shift on startup
Launch daemons and startup items are launched during system initialization by the system launchd process on behalf of root. Launch agents and login items are opened during the initialization of the GUI environment by the user's launchd process.
5. How does resetting the master filevault password affect existing filevault user accounts?
Code signed items include a digital signature that the system can use to verify the authenticity and integrity of the application or process and its resources.
They're stored at the root of every volume in a /.Spotlight-V100 folder. A fileVault user's database is stored in his vault in his home user. Mail is in ~/Library/Mail/Mail Envelope. Spotlight plugins can be in any library folder in a folder called S
If a known master password is reset - existing accounts are not negatively affected. If the master is reset because it was lost - however - preexisting accounts cannot be reset by the new password until the old FileVault passwords are reset.

Locally connected volumes are fully accessible to any logged in user.
Access is based on the local filesystem. They'll start in their home folder but can traverse anywhere they have permission to do so.

15. Five types of accounts in 10.6
Standard - Admin - Guest - Sharing-Only - Root
cp - mv - rm
The user's loginwindow process does the following: Request that all user applications quit - quits any user backgroun processes - runs any logout scripts - records the logout to the man system.log - resets device permissions and preferences to defaul
All users can read/write - but only the creator can delete. This uses the sticky bit.
