Q33. CORRECT TEXT

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.

Answer and Explanation:

1. vi /etc/sysconfing/network

NETWORKING=yes

HOSTNAME=station?.example.com

GATEWAY=192.168.0.254

2. service network restart

Or

1. vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=static

IPADDR=X.X.X.X

NETMASK=X.X.X.X

GATEWAY=192.168.0.254

2. ifdown eth0

3. ifup eth0


Q34. CORRECT TEXT

Your LAN is 192.168.0.0/24. Block the telnet connection from outside the LAN.

Answer and Explanation:

1. vi /etc/hosts.deny

in.telnetd:ALL EXCEPT 192.168.0.

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. Here in.telnetd is the telnet server program name.


Q35. CORRECT TEXT

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:

/ à 1048

/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. 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 should be in enforce mode.

Q36. CORRECT TEXT

Boot your System Successfully on runlevel 3. (Next Question)

Answer and Explanation:

This is boot related problem. There will be same questions repeated two times but problem is different.

First When you restart the system you will get the Error:

File Not Found

mount: error 15 mounting ext3

mount: error 2 mounting none

switchroot: mount failed: 22

umount /initrd/dev/: 2

Kernel Panic: no syncing: Attempted to kill init !

Restart the System

Check the grub boot loader configuration by pressing e shortcut key.

You will see like:

root (hd0,0)

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

initrd /initrd-2.6.9-5.EL.img

OR

root (hd0,0)

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

initrd /initrd-2.6.9-5.EL.img

Then Edit Boot loader to make like

root (hd0,0)

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

initrd /initrd-2.6.9-5.EL.img

Check all lines and edit as same as above. Press b to boot the system

After booting the system you should correct the /etc/grub.conf file.

If still you are getting Error like File not found, it seems that either kernel file or initrd file is missing.

To troubleshoot with these problem, boot the system on rescue mode.

i. linux rescue

ii. chroot /mnt/sysimage

iii. Check the files on /boot, if not available install the kernel package from ftp or nfs server

iv. Create the initrd image file on boot using: mkinitrd initrd-2.6.9-5.EL.img `uname -r`
