Configuring the NFS Service

Complete the following steps on your DHCP server.

1. Determine whether the NFS service package is already installed on the server by

typing the following command:

# rpm -qa | grep nfs-utils

2. If the NFS server package is not listed, install the package using yast by typing

the following command:

# yast -i nfs-utils

3. Edit and save the

/etc/exports

file to add the following line to it:

/home/pxeboot *(sync,no_root_squash,no_subtree_check,insecure)

4. Start the NFS service by typing the following command, as appropriate:

# /etc/init.d/nfsserver start

5. Configure the server to always start the NFS service by typing the following

commands:

# chkconfig nfslock on

# chkconfig nfsserver on

Note –

If you are using a DNS server, make sure that DNS entries exist for the range

of addresses defined in the pxe subnet

dynamic-bootp

entry in the

dhcpd.conf

file.

If you are not using a DNS server, edit the

/etc/hosts

file to add the range of host

addresses found in the pxe subnet

dynamic-bootp

entry in the

dhcpd.conf

file.

Disabling the Firewall

If a firewall is enabled on your PXE/DHCP server, make sure to disable it before
attempting to install the PXE image onto the client system.

Note –

When you disable the firewall protection on the system that is your PXE

server, the security of the data on that server cannot be assured. If this server is
networked outside of your local intranet, be sure to re-enable the firewall after
downloading software to PXE clients.
