Package Managenent

yum is a software package manager that installs, updates, and removes packages on  RPM-based systems. It automatically computes dependencies and figures out what things should occur to install packages. yum makes it easier to maintain groups of machines without having to manually update each one using rpm.
Features include:

• Support for multiple repositories
• Simple configuration
• Dependency calculation
• Fast operation
• RPM-consistent behavior
• Package group support, including multiple-repository groups
• Simple interface

yum uses an online repository by default, but you can also configure it to use a local repository of packages.

Change the IP address on RedHat.

Temporary Address

1)Open Terminal
2) ifconfig -a  
to list all network interface card on the current PC.
3) Type ifconfig eth0 [IP ADDRESS] netmask 255.255.255.0 up 
to configure IP Address on interface eth0.
4)route add default gw [Gateway Address]
to configure gateway

Permanemt Address

1) Open Terminal
2)# vi/etc/sysconfig/network-scripts/ifcfg-eth0
3)Modify the file by press ‘i’ to enter insert mode. Change BOOTPROTO to static and add IP Address and Net mask
             BOOTPROTO=static
             IPADDR=192.168.1.20
             NETMASK=255.255.255.0
Save the configuration file by press ESC + ‘:’ and type ‘wq’ to write and quit the editor.
4) Restart the network interface card. Type
# service network restart
#chkconfig on
5)Review the configuration. Type
#ifconfig

Assigning Multiple IP Address to a same NIC

Upto 256 IP Addrress can be assigned to the same NIC

# cd /etc/sysconfig/network-scripts
# vi ifcfg-eth0:0
DEVICE:eth0:0
BOOTPROTO=static
IPADDR=192.168.1.1
NETMASK=255.255.255.0
ONBOOT=yes

#service network restart

# ifconfig

Assigning Range of IP Addresses to the same NIC

# vi /etc/sysconfig/network-scripts/ifcfg-eth0-range0

IPADDR_START=192.168.1.2

IPADDR_END=192.168.1.31
CLONENUM_START=2

#service network restart

#ifconfig
#chkconfig network on
