Lab Exercise #2: Adding / Managing User Accounts with disk quotas, creating a DOS filesystem

1) Boot into Fedora

Add user2-5 using graphical method. Add user6-9 using command line “useradd”

Password = “password”.

Review /etc/passwd, /etc/shadow.

2) Add to /etc/fstab: /dev/sdax /home ext3 defaults,usrquota

3) quotacheck –m –c /home

4) Re-boot (shutdown -r now) or re-mount file partition (mount –a) with quotas.

5) Issue mount command, determine file systems with quotas:

Check /etc/mtab: /dev/sdax / ext3 rw,usrquota 0 0

6) quotacheck -vgum /home

7) quotaon -av

8) Set quotas to 1000MB (soft), 2000MB Hard for each user: edquota -u user_id

9) View quotas: quota -u user_id

10) Add to quota startup using book procedure

11) Use fdisk to create a 2GB VFAT partition (also look at at alternate parted command)

fdisk /dev/sda

m …. menu

n …. add partition (+(available size)

l …. list partition types

t b …. set partition type to WIN 95 FAT32

p …. to show results

w …. to write to disk

12) Format the new partition as vfat using the mkfs command

mkfs –t vfat /dev/sdax

13) Mount the partition on /mnt/dos

14) Copy over the contents of /home to /mnt/dos. How?

15) ls –al the contents of /home and /mnt/dos

16) Add /mnt/dos to /etc/fstab as a permanently mounted file system.
