5. You are new System Administrator and from now you are going to handle the system and your main
task is Network monitoring, Backup and Restore. But you don't know the root password. Change the root
password to redhat and login in default Runlevel.
Answer and Explanation:
When you Boot the System, it starts on default Runlevel specified in /etc/inittab: Id:?:initdefault:
When System Successfully boot, it will ask for username and password. But you don't know the root's
password. To change the root password you need to boot the system into single user mode. You can pass
the kernel arguments from the boot loader.
1. Restart the System.
2. You will get the boot loader GRUB screen.
3. Press a and type 1 or s for single mode ro root=LABEL=/ rhgb queit s
4. System will boot on Single User mode.
5. Use passwd command to change.

6. There are more then 400 Computers in your Office. You are appointed as a System Administrator. But
you don't have Router. So, you are going to use your One Linux Server as a Router. How will you enable
IP packets forward?
Answer and Explanation:
1. /proc is the virtual filesystem, we use /proc to modify the kernel parameters at running time.
# echo "1" >/proc/sys/net/ipv4/ip_forward
2. /etc/sysctl.conf when System Reboot on next time, /etc/rc.d/rc.sysinit scripts reads the file
/etc/sysctl.conf. To enable the IP forwarding on next reboot also you need to set the parameter.
net.ipv4.ip_forward=1
Here 0 means disable, 1 means enable.
7. You Completely Install the Redhat Enterprise Linux ES 4 on your System. While start the system, it's
giving error to load X window System. How will you fix that problem and make boot successfully run X
Window System.
Answer and Explanation:
Think while Problems occurred on booting System on Runlevel 5 (X Window).
1. /tmp is full or not
2. Quota is already reached
3. Video card or resolution or monitor is misconfigured.
4. xfs service is running or not.
Do These:
1. df -h /tmp /tmp is full remove the unnecessary file
2. quota username if quota is already reached remove unnecessary file from home directory.
3. Boot the System in runlevel 3. you can pass the Kernel Argument from boot loader.
4. Use command: system-config-display It will display a dialog to configure the monitor, Video card,
resolution etc.
5. Set the Default Runlevel 5 in /etc/inittab id:5:initdefault:
6. Reboot the System you will get the GUI login Screen.
8. There are two different networks, 192.168.0.0/24 and 192.168.1.0/24. Your System is in 192.168.0.0/24
Network. One RHEL 4 Installed System is going to use as a Router. All required configuration is already
done on Linux Server. Where 192.168.0.254 and 192.168.1.254 IP Address are assigned on that Server.
How will make successfully ping to 192.168.1.0/24 Network's Host?
Answer:
1. vi /etc/sysconfig/network
GATEWAY=192.168.0.254
OR
vi /etc/sysconf/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.0.?
NETMASK=255.255.255.0
GATEWAY=192.168.0.254
2. service network restart
Explanation: Gateway defines the way to exit the packets. According to question System working as a
router for two networks have IP Address 192.168.0.254 and 192.168.1.254. To get the hosts on
192.168.1.0/24 should go through 192.168.0.254.
