RHCE EXAM PART 2 (NETWORK SETUP)

AT the beginning your exam pc will get IP from DHCP server.

But for the exam you have to change the IP manually and set to the static mode.

Example:

# ifconfig –a

This command will show your current IP configuration

Now to change

1^st Method

# cd /etc/sysconfig/network-scripts/

# vim ifcfg-eth0

Initially this file will be look like this:

DEVICE=eth0

BOOTPROTO=dhcp

HWADDR=00:1E:68:9B:30:CB

ONBOOT=yes

But you have to change as per the exam requirement.

DEVICE=eth0

BOOTPROTO=static

HWADDR=00:1E:68:9B:30:CB

ONBOOT=yes

IPADDR=172.24.0.10

NETMASK=255.255.0.0

NETWORK=172.24.0.0

BROADCAST=172.0.255.255

To change DNS info

#  vim /etc/resolv.conf

Add/change this line

nameserver  172.24.0.254

Remember initially you may get an IP of class A but the examiner may give an IP of class B.

2^nd Method

# system-config-network

And give the IP information.

To check your hostname

# hostname –fqdn

To change hostname temporarily

# hostname station10.example.com

To change hostname permanently

# vim /etc/hosts

Add/change this line

172.24.0.10         station10.example.com       station10

# vim /etc/sysconfig/network

Add/change this line

HOSTNAME=station10.example.com
