Overview of Preboot Services Components
The following components are installed as part of Preboot Services:
Table 29-1
Preboot Service Components
The novell-proxydhcp daemon must be started manually and does not need to be run on all imaging
servers.
The other three daemons are started automatically when installing ZENworks Linux Management,
or any time the server is rebooted, and must run on all imaging servers.
For more information on these daemons, see Section D.7, “Imaging Server,” on page 605 .
Checking the Setup
After the Preboot Services components are installed, the following daemons should be installed and
running on the server:
Daemon Description
novell-pbserv The novell-pbserv daemon provides imaging services to devices.
novell-proxydhcp The novell-proxydhcp daemon runs alongside a standard DHCP server
to inform PXE devices of the IP address of the TFTP server. The Proxy
DHCP server also responds to PXE devices to indicate which bootstrap
program (
nvlnbp.sys
) to use.
novell-tftp The novell-tftp daemon is used by PXE devices to request files that are
needed to perform imaging tasks. The TFTP server also provides a
central repository for these imaging files, such as the Linux kernel, initrd,
and
nvlnbp.sys
.
A PXE device uses this server to download the bootstrap program
(
nvlnbp.sys
).
novell-zmgprebootpolicy The PXE devices use the novell-zmgprebootpolicy daemon to check if
there are any Preboot bundles that are assigned to the device.
