Q53. CORRECT TEXT

ssh service is enabled in your Server. Configure to

- Deny the ssh from cracker.org domain.

- Allow the ssh service only from example.com domain.

Answer and Explanation:

1. vi /etc/hosts.deny

sshd:ALL EXCEPT .example.com

1. vi /etc/hosts.deny

sshd:ALL

2. vi /etc/hosts.allow

sshd:.example.com

We can secure the services using tcp_wrappers. There are main two files, /etc/hosts.allow and /etc/hosts.deny.

There will be three stage access checking

- Is access explicitly permitted? Means permitted from /etc/hosts.allow?

- Otherwise, Is access explicitly denied? Means denied from /etc/hosts.deny?

- Otherwise, by default permit access if neither condition matched.

To deny the services we can configure /etc/hosts.deny file using ALL and EXCEPT operation.

Pattern of /etc/hosts.allow and /etc/hosts.deny file is:

Demon_list:client_list:options

In Client list can be either domain name or IP address.

Q54. CORRECT TEXT

Add a cron schedule to take full backup of /home on every day at 5:30 pm to /dev/st0 device.

Answer and Explanation:

1. vi /var/schedule

30 17 * * * /sbin/dump -0u /dev/st0 /dev/hda7

2. crontab /var/schedule

3. service crond restart

We can add the cron schedule either by specifying the scripts path on /etc/crontab file or by creating on text file on crontab pattern.

cron helps to schedule on recurring events. Pattern of cron is:

Minute Hour Day of Month Month Day of Week Commands

0-59 0-23 1-31 1-12 0-7 where 0 and 7 means Sunday.

Note * means every. To execute the command on every two minutes */2.

Q55. CORRECT TEXT

/storage directory on linux server should make available on windows system that jeff user should able to access on read only mode within example.com domain.

Answer and Explanation:

1. vi /etc/samba/smb.conf

[global]

netbios name=station?

workgroup=station?

security=user

smb passwd file=/etc/samba/smbpasswd

encrypt passwords=yes

hosts allow= .example.com

[data]

path=/data

public=no

writable=no

browsable=yes

2. smbpasswd -a jeff

3. service smb start

4. chkconfig smb on

/etc/samba/smb.conf. There are some pre-defined section, i. global à use to define the global options, ii. Printers à use to share the printers, iii. homes à use the share the user's home directory.

Security=user à validation by samba username and password. May be there are other users also.

To allow certain share to certain user we should use valid users option.

smbpasswd à Helps to change user's smb password. -a option specifies that the username following should be added to the local smbpasswd file.

Q56. CORRECT TEXT

Configure the send mail server for your local LAN. As well as the mail of user john should get by the jane user.

Answer and Explanation:

Here your Local LAN means your domain named example.com.

1. vi /etc/mail/local-host-names

example.com

2. vi /etc/mail/sendmail.mc

dnl # DEAMON_OPTIONS(`Port=smtp,Addr=127.0.0.1,Name=MTA`)dnl

3. m4 /etc/mail/sendmail.mc >/etc/mail/sendmail.cf

4. vi /etc/mail/access

192.168.0 RELAY

5. service sendmail start | restart

6. chkconfig sendmail on

/etc/mail/local-host-names file contains the aliases to hostname. Mail server program reads the

/etc/mail/sendmail.cf. To change the configuration on mail server, we should edit the

/etc/mail/sendmail.mc file and should generate the sendmail.cf using m4 command.

By default sendmail server allows to connect to local host only. So we should edit the

/etc/mail/sendmail.mc file to allow connect to other hosts.

By default sendmail server will not forward mail. we should specify on /etc/mail/access to relay or to block mail coming from domain or network or individual email address.

7. vi /etc/aliases

john: jane

8. newaliases

We can redirect the mail of one user to another user using /etc/aliases file. In example all mail of john goes to jane user.

Q57. CORRECT TEXT

/home à 1028

/boot à 512

/var à 1028

/usr à 2048

Swap -> 1.5 of RAM Size

/storageà configure the RAID Level 0 of remaining all free space.

After completing the installation through NFS solve the following questions. There are two networks 172.24.0.0/16 and 172.25.0.0/16.

Q59. CORRECT TEXT

There are three Disk Partitions /dev/hda8, /dev/hda9, /dev/hda10 having size 100MB of each partition. Create a Logical Volume named testvolume1 and testvolume2 having a size 250MB.

Mount each Logical Volume on lvmtest1, lvmtest2 directory.

Answer and Explanation:

Steps of Creating LVM:

1. pvcreate /dev/hda8 /dev/hda9 /dev/hda10

àpvdisplay command is used to display the information of physical volume.

2. vgceate test0 /dev/hda8 /dev/hda9 /dev/hda10

àvgdisplay command is used to display the information of Volume Group.

3. lvcreate -L 250M -n testvolume1 test0

à lvdisplay command is used to display the information of Logical Volume.

4. lvcreate -L 250M -n testvolume2 test0

5. mkfs -t ext3 /dev/test0/testvolume1

6. mkfs -t ext3 /dev/test0/testvolume2

7. mkdir /lvtest1

8. mkdir /lvtest2

9. mount /dev/test0/testvolume1 /lvtest1

10. mount /dev/test0/testvolume2 /lvtest2

11. 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.

Q60. CORRECT TEXT
