Install the dialog RPM package. . Use the remaining space to create a RAID 1 set on /dev/md1 and mounted this patition on /mnt/common . SELinux must be running in the Enforcing mode . neo user tried by: dd if=/dev/zero of=/home/neo/somefile bs=1024 count=100 file created successfully. Again neo tried to create file and having 170K using following command: dd if=/dev/zero of=/home/neo/somefile bs=1024 count=170 but he is unable to create the file. make the user can create the file less then 170K. . Some users home directory is shared from your system, using showmount -e localhost command, the share directory is not show, make access the share users home directory. . In your system has a logical volume is created named as common under vol0 volume group and is mount on /common, The initial size of that volume is 100MB,make successfully that the size of logical volume 190MB without losing any data. The size logical volume 160MB-200MB will be acceptable. . In your system has another logical volume is create name as shrink under vol0 volume group and is mount /shrink, The initial size of that valume is 320MB shrink successfully that the size of logical volume 200MB without losing any data, pay attention the size logical volume 192MB-240MB will be acceptable. Create a raid0 device /dev/md0 by creating equal two disks from available free space on your system and mount it on /raid0, when your system reboot this mounted directory should automatically mount on /raid0. . Make a swap partition have 512MB,make automatically useable at system boot time. . Create the following users,groups,and group memberships: - A group named admin - A user mary who belongs to admin as a secondary group - A user alice who also belongs to admin as a secondary group - A user bobby who dose not have access to an interactive shell on the system, and who is not a member of admin - mary,alice,and bobby should all have the passwd of password . Create a colloborative directory /common/admin with the following characteristics: - Group ownership of /common/admin is admin - The directory should be readable,writable,and accessiable to members of admin, but not to any other users.(It is understood that root has access to all files and directories on the system) - Files created in /common/admin automatically have group ownership set to the admin group .

Note the following: - guest200x should be able to log into your system, where x is your station number,but will not have a home directory until you have completed autofs requirement below - All NIS user have a password of password . Configure autofs to automount the home directory of NIS users. Note the following: - (54) NFS-exports /home/guests/guest200x to your system, where x is your station number - guest200x home directory is :/home/guests/guest200x - guest200x home directory should be automounted locally beneath /home/guests/guest200x - home dierctories must be writable by their users - While you are able to log in as any of users guest2001 through guest2020, the only home directory that is accessible from your system is guest200x. . Copy the file /etc/fstab to /var/tmp. Configure the permissions of /var/tmp/fstab so that: - the file /var/tmp/fstab is owned by root user - the file /var/tmp/fstab belongs to group root user - the file /var/tmp/fstab should not to be executable by anyone - the user mary is able to read and write /var/tmp/fstab - the user alice can neither write nor read /var/tmp/fstab - all other users(current of future) have the avility read /var/tmp/fstab .
