IPP( Internet Printing Protocol), allows administrator to manage printer through browser so CUPS is called Internet Printing Protocol based on HTTP. We can Install the printer either through: system-confing-printer tool or through Browser.

1. Open the browser and Type on address: http://localhost:631  CUPS (Common Unix Printing System) used the IPP protocol. CUPS use the 631 port.

2. Click on Manage Printer.

3. Click on Add Printer.

4. Type Printer name, Location, Description.

5. Select Device for bb. (Select IPP).

6. Device URL: ipp://192.168.0.254/ipp/ queue name  Same printer name of shared printer.

7. Select Model/Driver RAW printer.

8. service cups restart

Do the following steps as:

1. useradd jeff

2. useradd marion

3. useradd harold

useradd command is used to create the user. All user’s information stores in /etc/passwd and user;s shadow password stores in /etc/shadow.

Do the following steps as:

1. usermod -G sysusers jeff

2. usermod –G sysuser marion

3. Verify by reading /etc/group file

Using usermod command we can make user belongs to different group. There are two types of group one primary and another is secondary. Primary group can be only one but user can belongs to more than one group as secondary.

usermod -g groupname username  To change the primary group of the user

usermod -G groupname username  To make user belongs to secondary group.

Do the following steps as:

1. rpm -ivh ftp://server1.example.com/pub/updates/kernel-2.6.19-11.i686.rpm

2. vi /etc/grub.conf

default=1  Change this value to 1

timeout=5

splashimage=(hd0,0)/grub/splash.xpm.gz

hiddenmenu

title Red Hat Enterprise Linux ES (2.6.19-11)

root (hd0,0)

kernel /vmlinuz-2.6.19-11.EL ro root=LABEL=/ rhgb quiet

initrd /initrd-2.6.19-11.EL.img

title Red Hat Enterprise Linux ES (2.6.9-5.EL)

root (hd0,0)

kernel /vmlinuz-2.6.9-5.EL ro root=LABEL=/ rhgb quiet

initrd /initrd-2.6.9-5.EL.img

According question that kernel is available to anonymous user. You can directly install from the ftp server using rpm command.

When you install the kernel, it will write on /etc/grub.conf file. You can set the default kernel by changing the default value. See on the output of /etc/grub.conf file that new kernel is on first title so it’s index is 0 and previous kernel’s index is 1.

According to question, log server is already configured. We have to configure the mail, web and dns server for log redirection.

In mail, web and dns server:

1. vi /etc/syslog.conf

mail.* @logserveraddress

2. service syslog restart

mail is the facility and * means the priority. It sends logs of mail services into log server.

Redhat Enterprise Linux 5 Supports the RAID LEVEL 0, RAID LEVEL 1, RAID LEVEL 5 and RAID LEVEL 6 at installation time. You can create it at installation time later no need to type lots of commands for RAID.

At Installation Time:

Create the partitions using diskdruid.

Create the Partitions having File system Type Software RAID.

Click on RAID button

Type the Mount Point

Select File system type

Select RAID Level

Select Partitions/disks as a member of RAID.

Click on ok

After Installation: We can create the RAID Device after Installation on command-line.

Create the Two partitions having equal size. (Specify the Size using Cylinder, find the remaining cylinder and divide by 2).

Change the Partition ID to fd (Linux raid Autodetect) by typing t.

Type w  To write on partitions table.

Use partprobe command to synchronic the partition table.

Use: mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/hda? /dev/hda?

Verify the RAID: mdadm --detail /dev/md0

mkfs -t ext3 /dev/md0

mount /dev/md0 /data

vi /etc/fstab

/dev/md0 /data ext3 defaults 0 0

Verify mounting devices using mount command.

Do the following steps as:

1. Create a partition having size 5 GB and change the syste id ‘8e’.

2. use partprobe command

3. pvcreate /dev/hda9  Suppose your partition number is hda9.

4. vgextend test0 /dev/hda9  vgextend command add the physical disk on volume group.

5. lvextend –L+5120M /dev/test0/lvtestvolume

6. verify using lvdisplay /dev/test0/lvtestvolume.

Do the following steps as:

1. chmod 770 /data

2. 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

By default user1 can remove user2’s files due to directory permission to group member. We can prevent of deleting files from others users using Sticky Bits.

chmod o+t /data

Verify /data: ls -ld /data

You will get: drwxrwx—T

Do the following steps as:

1. chgrp sysuser /archive

2. Verify using ls -ld /archive command. You should get like

drwxr-x--- 2 root sysadmin 4096 Mar 16 17:59 /archive

chgrp command is used to change the group ownership of particular files or directory.

Another way you can use the chown command.

chown root:sysuser /archive
