Some users home directory is shared from your system. Using showmount -e localhost command, the shared directory is not shown. Make access the shared users home directory.

• A.Verify the File whether Shared or not ? : cat /etc/exports
  Start the nfs service: service nfs start
  Start the portmap service: service portmap start
  Make automatically start the nfs service on next reboot: chkconfig nfs on
  Make automatically start the portmap service on next reboot: chkconfig portmap on
  Verify either sharing or not: showmount -e localhost
  Check that default firewall is running on system ? if running flush the iptables using iptables -F and stop the iptables service.
• B.Verify the File whether Shared or not ? : cat /etc/exports
  Start the nfs service: service nfs start
  Make automatically start the portmap service on next reboot: chkconfig portmap on
  Verify either sharing or not: showmount -e localhost
  Check that default firewall is running on system ? if running flush the iptables using iptables -F and stop the iptables service.

There are two different networks 192.168.0.0/24 and 192.168.1.0/24. Where
192.168.0.254 and 192.168.1.254 IP Address are assigned on Server. Verify your network settings by pinging 192.168.1.0/24 Network's Host.

• A.At exam time read the Lab Scenario carefully. Actually there are two different networks one is 192.168.0.0/24 where your system resides know as example.com domain and another is 192.168.1.0/24 know as cracker.org domain. One server named sever1.example.com having 192.168.0.254 and 192.168.1.254 is running in your exam. If you make a gateway to that server, you will can ping because IP forwarding is enabled on that server.
  1. vi /etc/sysconfing/network NETWORKING=yes
  HOSTNAME=station?.example.com GATEWAY=192.168.0.254
  2. service network restart Or

Create the partition having 100MB size and mount it on /mnt/neo

• A.Use fdisk /dev/hda To create new partition.
  Type n For New partitions
  It will ask for Logical or Primary Partitions. Press l for logical.
  It will ask for the Starting Cylinder: Use the Default by pressing Enter Key.
  Type the Size: +100M You can Specify either Last cylinder of Size here.
  Press P to verify the partitions lists and remember the partitions name.
  Press w to write on partitions table.
  Either Reboot or use partprobe command.
  Use mkfs -t ext3 /dev/hda? ->Where ? is your partition number
  Or mke2fs -j /dev/hda? To create ext3 filesystem.
  mkdir /mnt/neo
  vi /etc/fstab
  Write:
  /dev/hda? /mnt/neo ext3 defaults 1 2
  Verify by mounting on current Sessions also:
  mount /dev/hda? /mnt/neo

There are three Disk Partitions /dev/hda8, /dev/hda9, /dev/hda10 having size 100MBof each partition. Create a Logical Volume named testvolume1 and testvolume2 having a size 250MB. Mount each Logical Volume on lvmtest1, lvmtest2 directory.

• A.Steps of Creating LVM:
  pvcreate /dev/hda8 /dev/hda9 /dev/hda10
  pvdisplay command is used to display the information of physical volume.
  vgceate test0 /dev/hda8 /dev/hda9 /dev/hda10
  Physical Disk1 Logical Volume 1
  Physical Disk2
  Physical Disk3 Physical Volume Volume Group Logical Volume 2
  Logical Volume 3
  ->vgdisplay command is used to display the information of Volume Group.
  lvcreate -L 250M -n testvolume1 test0
  ->lvdisplay command is used to display the information of Logical Volume.
  lvcreate -L 250M -n testvolume2 test0
  mkfs -t ext3 /dev/test0/testvolume1
  mount /dev/test0/testvolume2 /lvtest2
  vi /etc/fstab /dev/test0/testvolume2 /lvtest2 ext3 defaults 0 0 /dev/test0/testvolume1 /lvtest1 ext3 defaults 0 0 To create the LVM( Logical Volume Manager) we required the disks having '8e' Linux LVM type. First we should create the physical Volume, then we can create the Volume group from disks belongs to physical Volume. lvcreate command is used to create the logical volume on volume group. We can specify the size of logical volume with -L option and name with -n option.
• B.Steps of Creating LVM:
  pvcreate /dev/hda8 /dev/hda9 /dev/hda10
  pvdisplay command is used to display the information of physical volume.
  vgceate test0 /dev/hda8 /dev/hda9 /dev/hda10
  Physical Disk1 Logical Volume 1
  Physical Disk2
  Physical Disk3 Physical Volume Volume Group Logical Volume 2
  Logical Volume 3
  ->vgdisplay command is used to display the information of Volume Group.
  lvcreate -L 250M -n testvolume1 test0
  ->lvdisplay command is used to display the information of Logical Volume.
  lvcreate -L 250M -n testvolume2 test0
  mkfs -t ext3 /dev/test0/testvolume1
  mkfs -t ext3 /dev/test0/testvolume2
  mkdir /lvtest1
  mkdir /lvtest2
  mount /dev/test0/testvolume1 /lvtest1
  mount /dev/test0/testvolume2 /lvtest2
  vi /etc/fstab /dev/test0/testvolume2 /lvtest2 ext3 defaults 0 0 /dev/test0/testvolume1 /lvtest1 ext3 defaults 0 0 To create the LVM( Logical Volume Manager) we required the disks having '8e' Linux LVM type.

There is one partition /dev/hda14 mounted on /data. The owner of /data is root user and root group. And Permission is full to owner user, read and execute to group member and no permission to others. Now you should give the full permission to user user1 without changing pervious permission.

• A.We know that every files/directories are owned by certain user and group. And Permissions are defines to owner user, owner group and other.
  -rwxr-x----> Full permission to owner user, read and write to owner group and no permission to others. According to QUESTION: We should give the full permission to user user1 without changing the previous permission. ACL (Access Control List), in ext3 file system we can give permission to certain user and certain group without changing previous permission. But that partition should mount using acl option. Follow the steps
  vi /etc/fstab /dev/hda14 /data ext3 defaults,acl 0 1
  Either Reboot or use: mount -o remount /data
  setfacl -m u:user1:rwx /data
  Verify using: getfacl /data
• B.We know that every files/directories are owned by certain user and group. And Permissions are defines to owner user, owner group and other.
  -rwxr-x----> Full permission to owner user, read and write to owner group and no permission to others. According to QUESTION: We should give the full permission to user user2 without changing the previous permission. ACL (Access Control List), in ext3 file system we can give permission to certain user and certain group without changing previous permission. But that partition should mount using acl option. Follow the steps
  vi /etc/fstab /dev/hda15 /data ext3 defaults,acl 0 5
  Either Reboot or use: mount -o remount /data
  setfacl -m u:user1:rwx /data
