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.
