Backup of the Redhat Enterprise Linux 5 is on /var/ftp/pub, /var/www/html/pub on server named server1.example.com. You can install all required packages using yum by creating the repository file.
Answer and Explanation:
1. Create the repository file
#vi /etc/yum.repos.d/server1.repo
[station?]
name=station?
baseurl=ftp://server1.example.com/pub/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
# yum install
Install the Redhat Linux RHEL 5 through NFS. Where your Server is server1.example.com having IP 172.24.254.254 and shared /var/ftp/pub. The size of the partitions are listed below:
/1048
/home1028
/boot 512
/var 1028
/usr2048
Swap->1.5 of RAM Size
/archiveconfigure 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. As well as there are two domains example.com on 172.24.0.0/16 network and my133t.org on 172.25.0.0/16 network. Your system is based on example.com domain. SELinux must be in enforcing mode.
Answer and Explanation:
1. Insert the CD on CD-ROM and start the system.
2. In Boot: Prompt type linux askmethod
3. It will display the language, keyboard selection.
4. It will ask you for the installation method.
5. Select the NFS Image from the list
6. It will ask the IP Address, Net mask, Gateway and Name Server. Select Use
Dynamic IP Configuration: because DHCP Server will be configured in your exam lab.
7. It will ask for the NFS Server Name and Redhat Enterprise Linux Directory.
Specify the NFS Server: 172.24.254.254
Directory: /var/ftp/pub
8. After Connecting to the NFS Server Installation start in GUI. Go up to the partition screen by selecting the different Options.
9. Create the partition According to the Question because Size and what-what partition should you create at installation time is specified in your question
10.Create the two RAID partitions having equal size of remaining all free space.
11.Click on RAID button
12.Type mount point /archive
13.Select RAID Level 0
14.Click on ok
15. Then select the MBR Options, time zone and go upto package selections.
It is another Most Important Time of installation. Due to the time limit, you should care about the installation packages. At Exam time you these packages are enough.

Create the user named jackie, curtin, david
Answer and Explanation:
1.useradd jackie
2.useradd curtin
3. useradd david
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.
Create the directory /archive and group owner should be the sysuser group.
Answer and Explanation:
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
Your System is going to use as a Router for two networks. One Network is 192.168.0.0/24 and Another Network is 192.168.1.0/24. Both network’s IP address has assigned. How will you forward the packets from one network to another network?
Answer and Explanation:
1.echo “1” >/proc/sys/net/ipv4/ip_forward
2.vi /etc/sysctl.conf
net.ipv4.ip_forward = 1
If you want to use the Linux System as a Router to make communication between different networks, you need enable the IP forwarding. To enable on running session just set value 1 to /proc/sys/net/ipv4/ip_forward. As well as automatically turn on the IP forwarding features on next boot set on /etc/sysctl.conf file.
Create the user named user1, user2, user3
Answer and Explanation:
useradd user1
useradd user2
useradd user3
passwd user1
passwd user2
passwd user3
We create the user using useradd command and we change the password of user using passwd command. If you want to set the blank password use: passwd -d username.
One Domain RHCE is configured in your lab, your domain server is server1.example.com. nisuser2001, nisuser2002, nisuser2003 user are created on your server 192.168.0.254:/rhome/stationx/nisuser2001. Make sure that when NIS user login in your system automatically mount the home directory. Home directory is separately shared on server /rhome/stationx/ where x is your Station number.
Answer and Explanation:
1. use the authconfig --nisserver=
Example: authconfig --niserver=192.168.0.254 --nisdomain=RHCE --update
or system-config-authentication
2. Click on Enable NIS
3. Type the NIS Domain: RHCE
4. Type Server 192.168.0.254 then click on next and ok
5. You will get a ok message.
6. Create a Directory /rhome/stationx where x is your station number.
6. vi /etc/auto.master and write at the end of file
/rhome/stationx /etc/auto.home --timeout=60
7. vi /etc/auto.home and write
* -rw,soft,intr 192.168.0.254:/rhome/stationx/&
Note: please specify your station number in the place of x.
8. Service autofs restart
9. Login as the nisuser2001 or nisuser2002 on another terminal will be
Success.
According to question, RHCE domain is already configured. We have to make a client of RHCE domain and automatically mount the home directory on your system. To make a member of domain, we use the authconfig with option or system-config-authentication command. There a are lots of authentication server i.e NIS, LDAB, SMB etc. NIS is a RPC related Services, no need to configure the DNS, we should specify the NIS server address.
Here Automount feature is available. When user tried to login, home directory will automatically mount. The automount service used the /etc/auto.master file. On /etc/auto.master file we specified the mount point the configuration file for mount point.
Add a user named user4 and make primarily belongs to training group. As well account should expire on 30 days from today.
Answer and Explanation:

Create the user named eric and deny to interactive login.
Answer and Explanation:
useradd eric
passwd eric
vi /etc/passwd
eric:x:505:505::/home/eric:/sbin/nologin
Which shell or program should start at login time is specified in /etc/passwd file. By default Redhat Enterprise Linux assigns the /bin/bash shell to the users. To deny the interactive login, you should write /sbin/nologin or /bin/false instead of login shell.
