+Install DHCPD and TFTPD server from OS distribution. You can do it with the following YUM command:
+{{{
+yum install dhcp tftp-server
+}}}
+
+If the DHCP server is to be used for Quattor usage only, a basic DHCP configuration (`/etc/dhcpd.conf`) may be:
+{{{
+# DHCP server configuration
+
+authoritative;
+allow bootp;
+#allow duplicates;
+ddns-update-style none;
+#omapi-port 7921;       # Use a non standard port (standard = 7911)
+
+# Edit to reflect your DNS domain name and name servers (a comma-separated list is allowed)
+option domain-name "lal.in2p3.fr";
+option domain-name-servers nfsserv.lal.in2p3.fr;
+option netbios-node-type 2;
+
+# Update to reflect your IP subnet
+subnet 134.158.72.0 netmask 255.255.255.254 {
+
+  # Parameters for the installation via PXE using pxelinux
+  filename                           "quattor/pxelinux.0";
+  #option dhcp-class-identifier       "PXEClient";
+  option vendor-encapsulated-options 01:04:00:00:00:00:ff;
+
+  # This is now a required line in DHCP configuration.  This
+  # option gives the behavior of the previous versions.
+  ddns-update-style ad-hoc;
+
+  option routers 134.158.72.1;
+}
+}}}
+
+If you want to share DHCP between Quattor and non Quattor usage, it's probably better to move the last part (`subnet...`) into a separate file, like `/etc/dhcpd/quattor.conf` and replace it in the main configuration file by:
+{{{
+include "/etc/dhcpd/quattor.conf";
+}}}
+
+See `man dhcpd` and `man dhcpd.conf` for details about DHCP server configuration, in particular to support multiple subnets and other advanced features.
+
+TFTP server is run by `xinetd`. In the default configuration, it is disabled. Enable it by editing `/etc/xinetd.d/tftp`, modifying `disable` parameter from `yes` to `no`.
+
+Note that default location for TFTP root in AII configuration files is {{{/osinstall/nbp}}}. It must be explicitly defined if you want to use {{{/tftpboot}}} or another location.
