The System you are using is for NFS (Network File Services). Some important data are shared from your system. Make automatically start the nfs and portmap services at boot time.

• A.  We can control the services for current session and for next boot time also. For current Session, we use service servicename start or restart or stop or status.
  Select the nfs and portmap services.
  Reboot the system and identify whether services are running or not.
• B.  We can control the services for current session and for next boot time also. For current Session, we use service servicename start or restart or stop or status. For automatically on next reboot time:
  3. chkconfig servicename on or off eg: chkconfig nfs on chkconfig portmap on
  or
  ntsysv
  Select the nfs and portmap services.
  Reboot the system and identify whether services are running or not.

Make on /data that only the user owner and group owner member can fully access.

• A.  chmod 770 /data
  Verify using : ls -ld /data Preview should be like: drwxrwx--- 2 root sysadmin 4090 Mar 16 18:08 /data To change the permission on directory we use the chmod command. According to the QUESTION that only the owner user (root) and group member (sysadmin) can fully access the directory so: chmod 760 /data
• B.  chmod 770 /data
  Verify using : ls -ld /data Preview should be like: drwxrwx--- 2 root sysadmin 4096 Mar 16 18:08 /data To change the permission on directory we use the chmod command. According to the QUESTION that only the owner user (root) and group member (sysadmin) can fully access the directory so: chmod 770 /data

neo user tried by: dd if=/dev/zero of=/home/neo/somefile bs=1024 count=70 files created successfully. Again neo tried to create file having 70K using following command: dd if=/dev/zero of=/home/neo/somefile bs=1024 count=70 But he is unable to create the file. Make the user can create the file less then 70K.

• A.  Very Tricky question from redhat. Actually question is giving scenario to you to implement quota to neo user. You should apply the quota to neo user on /home that neo user shouldn't occupied space more than 70K.
  1. vi /etc/fstab
  LABEL=/home /home ext3 defaults,usrquota 0 0 -> To enable the quota on filesystem you should mount the filesystem with usrquota for user quota and grpquota for group quota.
  touch /home/aquota.user-> Creating blank quota database file.
  mount -o remount /home ->Remounting the /home with updated mount options. You can verify that /home is mounted with usrquota options or not using mount command.
  quotacheck -u /home ->Initialization the quota on /home
  edquota -u neo /home-> Quota Policy editor
  See the snapshot 1 Disk quotas for user neo (uid 500): 2 Filesystem blocks soft hard inodes soft hard
  4 /dev/mapper/vo-myvol 2 30 70 1 0 0 Can you set the hard limit 70 and soft limit as you think like 30. Verify using the repquota /home command.
• B.  Very Tricky question from redhat. Actually question is giving scenario to you to implement quota to neo user. You should apply the quota to neo user on /home that neo user shouldn't occupied space more than 70K.
  1. vi /etc/fstab
  LABEL=/home /home ext4 defaults,usrquota 0 0 -> To enable the quota on filesystem you should mount the filesystem with usrquota for user quota and grpquota for group quota.
  touch /home/aquota.user-> Creating blank quota database file.
  mount -o remount /home ->Remounting the /home with updated mount options. You can verify that /home is mounted with usrquota options or not using mount command.
  quotacheck -u /home ->Initialization the quota on /home
  edquota -u neo /home-> Quota Policy editor
  See the snapshot 1 Disk quotas for user neo (uid 500): 2 Filesystem blocks soft hard inodes soft hard
  4 /dev/mapper/vo-myvol 2 31 75 1 1 1 Can you set the hard limit 70 and soft limit as you think like 50. Verify using the repquota /home command.

Whoever creates the files/directories on /data group owner should be automatically should be the same group owner of /data.

• A.  chmod g+s /data
  Verify using: ls -ld /data Permission should be like: drwxrws--- 2 root sysadmin 4096 Mar 16 18:08 /data If SGID bit is set on directory then who every users creates the files on directory group owner automatically the owner of parent directory. To set the SGID bit: chmod g+s directory To Remove the SGID bit: chmod g-s directory
• B.  chmod g+s /data
  Verify using: ls -ld /data Permission should be like: drwxrws--- 3 root sysadmin 4096 Mar 16 10:08 /data If SGID bit is set on directory then who every users creates the files on directory group owner automatically the owner of parent directory.

Successfully resolv to server1.example.com where your DNS server is 172.24.254.254

• A.  1. vi /etc/resolv.conf
  nameserver 172.24.254.254
  2. host server1.example.com On every clients, DNS server is specified in /etc/resolv.conf. When you request by name it tries to resolv from DNS server .
• B.  1. vi /etc/resolv.conf
  nameserver 172.25.254.255
  2. host server1.example.com On every clients, DNS server is specified in /etc/resolv.conf. When you request by name it tries to resolv from DNS server .
