Setting up a PXE BOOT server @RHEL,FEDORA

#This is a configuration script for making a pxe boot server for rhel
#Packages needed are
#1.sylinux
#2.any server to share rhel cd/dvd source and kickstarts ---here ve use httpd
#3.kickstart
#4.tftp-server
#5.xinet
#6.dhcp

#configuring the httpd

Setting DHCP server in rhel ,fedora

#Steps to Configure dhcp...
#First give static ip for the server machine ie dhcp server

#1.Packages needed
#-dhcp-

yum -y install dhcp

#2.Copying the config file from
#    /usr/share/doc/dhcp*/dhcpd.conf to /etc/dhcp/dhcpd.conf
echo "Configuration files are"
rpm -qc dhcp

#3.Opening the config file
vim /etc/dhcp/dhcpd.conf

#4.Starting and Chkconfig the service . After adding needed subnetworks

service dhcpd start
chkconfig dhcpd on

echo "Service started and chkconfig is on"

# Hosts which require special configuration options can be listed in
# host statements.   If no address is specified, the address will be
# allocated dynamically (if possible), but the host-specific information
# will still come from the host declaration.

#host passacaglia {
#  hardware ethernet 0:0:c0:5d:bd:95;
#  filename "vmunix.passacaglia";
#  server-name "toccata.fugue.com";
#}

# Fixed IP addresses can also be specified for hosts.   These addresses
# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
# BOOTP or DHCP.   Hosts for which no fixed address is specified can only
# be booted with DHCP, unless there is an address range on the subnet
# to which a BOOTP client is connected which has the dynamic-bootp flag
# set.
#host fantasia {
#  hardware ethernet 08:00:07:26:c0:a5;
#  fixed-address fantasia.fugue.com;
#}

# You can declare a class of clients and then do address allocation
# based on that.   The example below shows a case where all clients
# in a certain class get addresses on the 10.17.224/24 subnet, and all
# other clients get addresses on the 10.0.29/24 subnet.
