Overview 7 © R. Craig Collins, 2005/6

•Read Creating Users, below

• log on
• details
• password
    *assigned, never change
    *assigned, allow change (how often?)
    *assigned, force change (when?)
• contact info
• group
    *as whe have yet to discuss creating groups, we must assume there are some already created. They are
      -administrators: lots of rights, that can't be adjusted
      -guests: few of rights, that can't be adjusted
      -users: everyone is a member of this group
    *We can create other groups as well.
      -distribution groups, just for group emailing
      -security groups: every other kind of group is a security related group
    *Since 2003 can be a domain, among trees or among forests, group members must match. They are
      -domain local groups: permission in the local domain they are placed in
      -global groups: permission in the trees of other trusted domains
      -universal groups: permission in the whole forest

•Activities Users and Templates Windows

1. Manually add user Windows
   Specifications
   1. In Windows Server command prompt
      dsadd /?
   2. To create one user using DSADD, named Kent C Deforest
      dsadd user "cn=Kent C Deforest,cn=users,dc=your domain,[dc=522,]dc=templejc,dc=edu"
      Note: Other DSADD options you may add:
      -pwd value - memberof "cn=value" -profile "\\server\profiles\value" -disabled no
      Other DS related command DSMOD and DSMOVE and DSQUERY
      dsmod /?
      dsmove /?
      dsquery /?
      
2. Graphically add user Windows
   1. Click Start, select Administrative Tools, and then click Active Directory Users and Computers
      Right Click the Users container, and select New, and click User
   2. Example
      Create one user graphically, named Warren Peese;
      username wpeese,
      password Password1
   3. Right click the users and to Memberof add Server Operators, not full administrator
      (in this class, all users need to be server operators or administrators in order to 'sit at' this machine.)
      
3. Automating user creation, by creating a template with all memberof, dialin, etc., already set
   1. Creating a user Template
      Example
      • Right Click the Users container, and select New, and click User
      • In the New Object-User dialog box, type _Template in the First name text box
        (the _ ensures the templat account appears at the top of the user listing)
      • Press Tab four times to reach the User Logon name field. Type template and choose Next.
      • In the Password text box, type Password1, and again for the confirm password.
      • Right click the _Template user account, and choose Properties
      • In the description text box on the General tab, type typical user
      • Click the Profile tab, for the path \\your server's name\profiles\%username%
        (this will automatically create profiles based on the user name
      • Click the Memberof tab and add the template as a memberof Server Operators
   • To Create one user via Template, named Ima Clone
     Specifications
     • Right click the _Template user account and click copy
     • User name Ima Clone, and username iclone, password Password1
4. Now create resources and groups to test the server

• Create a folder named Faculty, and place within it a text document perhaps is named "Faculty.txt"
  
• Create a folder named Students, and place within it a text document that is named "Students.txt"
• Create a group called Faculty (local, security)
• Create a group called Students (local, security)

• Right click on folder, choose Properties
• Under Sharing, share the folder
• Under security, add Faculty, then set permissions
• Under security, add Students, then set permissions
• Under security, remove permissions for the generic user group
  
  Create a student user and add them to your student group,
  Create a faculty user and them to the faculty group..
  
  Recall, in this class, all users also have to be members of Server Operator
  Note: record username, password, and group information in your notes
• Test both users, verify faculty can see and change both files, but
  students can see both files, but only change the student file.

•Activities Users and Templates Linux
1. Optional Manually add user Linux
    Specifications

• In Linux Server command prompt
  whatis useradd
• To create one user using useradd, named Kent C Deforest

PS Don’t name your user faculty, then your group faculty, and then a folder faculty. This will lead to confusion later, use different, meaningful names.

2. System Administration: Users and Groups
Create two ‘New users,’ such as
Username (User ID for logon) fflintstone001,
Full Name Fred Flintstone
Password Password2

Username (User ID for logon) bruble001,
Full Name Barney Ruble
Password Password2

Create two ‘New groups,’ such as
Students
Faculty

3. Open up the Linux equivalent of (My) Computer, and browse to the ‘home’ folder.

Create a folder called Share
using chmod, set Share to 777
probably will need to use something like
chmod 777 /home/Share
so everyone has read write execute.
We will alter individual folders inside of Share later

(In Windows, we created the Users folder during the server set up… we are now playing catch up.)

Create a new folder called FacultyStuff in the Share folder
Create a new folder called StudentStuff in the Share folder

As these folders were created by you the administrator, you would now need to change the group affiliation to the correct group.

   • to change which group a file belongs to, use chgrp
     chgrp groupname file or folder, such as
chgrp Faculty /home/Share/FacultyStuff

    (to change which owner (user) a file belongs to, use chown
     chown ownername file or folder)

•Controlling not just the folders, but the drive the folders are saved on: Dynamic Disks

RAID concepts

• RAID 0: minimum two disks, stripped without parity-no fault tolerance
• RAID 1; minimum two disks, mirrored without parity-basic fault tolerance
• RAID 3,4; minimum three disks, with dedicated parity- parity drive can fail-fault tolerance
• RAID 5; minimum three disks, with striped parity- any drive can fail- fault tolerance
• RAID 6; minimum four disks, with striped parity- any two drives can fail- fault tolerance
