N(" - Create Etherboot Enabled Boot Images:
To boot a kernel via etherboot, a special kernel/initrd image must be created.
mkinitrd-net does much of this work and drakTermServ is just a graphical
interface to help manage/customize these images. To create the file
/etc/dhcpd.conf.etherboot-pcimap.include that is pulled in as an include in
dhcpd.conf, you should create the etherboot images for at least one full kernel.") . "\n\n" .
N(" - 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.
(PCI cards may omit the image - etherboot will request the correct image.
You should also consider that when etherboot looks for the images, it expects
names like boot-3c59x.nbi, rather than boot-3c59x.2.4.19-16mdk.nbi).
A typical dhcpd.conf stanza to support a diskless client looks like:") . "\n\n" .
' host curly {
hardware ethernet 00:20:af:2f:f7:9d;
fixed-address 192.168.192.3;
#type fat;
filename "i386/boot/boot-3c509.2.4.18-6mdk.nbi";
#hdw_config true;
}
' . "\n" .
N(" 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: The '#type' entry is only used by drakTermServ. Clients can either be 'thin'
or 'fat'. Thin clients run most software on the server via xdmcp, while fat clients run
most software on the client machine. A special inittab, %s is
written for thin clients. System config files xdm-config, kdmrc, and gdm.conf are
modified if thin clients are used, to enable xdmcp. Since there are security issues in
using xdmcp, hosts.deny and hosts.allow are modified to limit access to the local
subnet.
Note: The '#hdw_config' entry is also only used by drakTermServ. Clients can either
be 'true' or 'false'. 'true' enables root login at the client machine and allows local
hardware configuration of sound, mouse, and X, using the 'drak' tools. This is enabled
by creating separate config files associated with the client's IP address and creating
read/write mount points to allow the client to alter the file. Once you are satisfied
with the configuration, you can remove root login privileges from the client.
Note: You must stop/start the server after adding or changing clients.", $inittab_str) . "\n\n" .
N(" - 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)
/home SUBNET/MASK(rw,root_squash)
With SUBNET/MASK being defined for your network.") .
"\n\n" .
N(" - Maintain %s:
For users to be able to log into the system from a diskless client, their entry in
/etc/shadow needs to be duplicated in %s. drakTermServ
helps in this respect by adding or removing system users from this file.", $shadow_str, $shadow_str) . "\n\n" .
N(" - Per client %s:
Through clusternfs, each diskless client can have its own unique configuration files
on the root filesystem of the server. By allowing local client hardware configuration,
drakTermServ will help create these files.", $xfconfig_str) .
"\n\n" .
N(" - Per client system configuration files:
Through clusternfs, each diskless client can have its own unique configuration files
on the root filesystem of the server. By allowing local client hardware configuration,
clients can customize files such as /etc/modules.conf, /etc/sysconfig/mouse,
/etc/sysconfig/keyboard on a per-client basis.
Note: Enabling local client hardware configuration does enable root login to the terminal
server on each client machine that has this feature enabled. Local configuration can be
turned back off, retaining the configuration files, once the client machine is configured.") . "\n\n" .
N(" - /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 its images.") . "\n\n" .
N(" - 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/floppyload.bin \\
/usr/share/etherboot/start16.bin \\
