+# 4) add/remove entries in /etc/shadow$$CLIENTS$$ to allow user access
+# 5) per client XF86Config-4, using /etc/XF86Config-4$$IP-ADDRESS$$
+# 6) other per client customizations (modules.conf, keyboard, mouse)
+# 7) enable/modify /etc/xinetd.d/tftp for etherboot
+# 8) create etherboot floppies for client machines

+
+ - Create Etherboot Enabled Boot Images:
+ To boot a kernel via etherboot, a special kernel/initrdrd image must be created.
+ mkinitrd-net does much of this work and drakTermServ is just a graphical interface
+ to help manage/customize these images.
+
+ - Maintain /etc/dhcpd.conf:
+ To net boot clients, each client needs a dhcpd.conf entry, assigning an IP address
+ and net boot images to the machine. drakTermServ helps create/remove these entries.
+
+ A typical dhcpd.conf stanza to support a diskless client looks like:
+
+ host curly {
+ hardware ethernet 00:20:af:2f:f7:9d;
+ fixed-address 192.168.192.3;
+ filename \"i386/boot/boot-3c509.2.4.18-6mdk.nbi\";
+ }
+
+ While you can use a pool of IP addresses, rather than setup a specific entry for
+ a client machine, using a fixed address scheme facilitates using the functionality
+ of client-specific configuration files that ClusterNFS provides.
+
+ Note: You must stop/start the server after adding or changing clients/
+
+ - Maintain /etc/exports:
+ Clusternfs allows export of the root filesystem to diskless clients. drakTermServ
+ sets up the correct entry to allow anonymous access to the root filesystem from
+ diskless clients.
+
+ A typical exports entry for clusternfs is:
+
+ / (ro,all_squash)
+
+ - Maintain /etc/shadow\$\$CLIENT\$\$:
+ For users to be able to log into the system from a diskless client, their entry in
+ /etc/shadow needs to be duplicated in /etc/shadow\$\$CLIENTS\$\$. drakTermServ helps
+ in this respect by adding or removing system users from this file.
+
+ - Per client /etc/X11XF86Config-4\$\$IP-ADDRESS\$\$:
+ Through clusternfs, each diskless client can have it's own unique configuration files
+ on the root filesystem of the server. In the future drakTermServ will help create these
+ files.
+
+ - Per client system configuration files:
+ Through clusternfs, each diskless client cand have it's own unique configuration files
+ on the root filesystem of the server. In the future, drakTermServ can help create files
+ such as /etc/modules.conf, /etc/sysconfig/mouse, /etc/sysconfig/keyboard on a per-client
+ basis.
+
+ - /etc/xinetd.d/tftp:
+ drakTermServ will configure this file to work in conjunction with the images created by
+ mkinitrd-net, and the entries in /etc/dhcpd.conf, to serve up the boot image to each
+ diskless client.
+
+ A typical tftp configuration file looks like:
+
+ service tftp
+ (
+ disable = no
+ socket_type = dgram
+ protocol = udp
+ wait = yes
+ user = root
+ server = /usr/sbin/in.tftpd
+ server_args = -s /var/lib/tftpboot
+ }
+
+ The changes here from the default installation are changing the disable flag to
+ 'no' and changing the directory path to /var/lib/tftpboot, where mkinitrd-net
+ puts it's images.
+
+ - Create etherboot floppies/CDs:
+ The diskless client machines need either ROM images on the NIC, or a boot floppy
+ or CD to initate the boot sequence. drakTermServ will help generate these images,
+ based on the NIC in the client machine.
+
+ A basic example of creating a boot floppy for a 3Com 3c509 manually:
+
+ cat /usr/lib/etherboot/boot1a.bin /\
+ /usr/lib/etherboot/lzrom/3c509.lzrom > /dev/fd0
