Pxe Devices And Server Referral Lists - Novell ZENWORKS 10 CONFIGURATION MANAGEMENT SP3 - MIGRATION GUIDE 10.3 30-03-2010 Migration Manual

For eDirectory login, you must provide a fully distinguished user name that has sufficient rights to
read eDirectory. Writing to eDirectory is not required because the migration process only reads
eDirectory. If you are migrating images, the migration user must also have rights to read
imaging files.
For reading information from eDirectory, the default port for LDAP SSL is 636. The default non-
LDAP SSL port is 389.
Although you can migrate without Novell Client32
the migration utility, Client32 might be necessary to access files on NetWare
Authentication to the ZENworks Management Zone is done using the administrator login name and
password that you established when installing Configuration Management. If you added other
administrator logins in ZENworks Control Center after installation, these are also valid, provided
they have the necessary Read rights to eDirectory and Write rights to the ZENworks Configuration
Management database.
For writing to the zone's database, the default port for SSL is 443.

3.4.3 PXE Devices and Server Referral Lists

If you have both Configuration Management and ZENworks Linux Management systems running
concurrently, the following information might apply:
PXE Devices: When a PXE device boots, it makes a broadcast request on the network for PXE
services. The ZENworks Proxy DHCP server (the
this request with information that includes the IP address of an imaging server where the device
can send requests for assigned preboot work.
Because PXE devices can exist in an environment with both newer and traditional ZENworks
systems running concurrently, the device can fail to determine its assigned preboot work if it
cannot find the imaging server for its own ZENworks version.
In ZENworks Configuration Management, devices can exist in multiple Management Zones. It
is essential that the PXE device contact PXE services associated with its home zone so that it
can correctly determine if there is any preboot work assigned to it. When there is only a single
Management Zone, this is easy to do because all Proxy DHCP servers provide addresses to
services that belong to the same zone. Any device can request preboot work from any imaging
server in the same zone and get the same response.
The PXE device's initial request for PXE services is sent as a broadcast to the network, and all
Proxy DHCP servers respond with information pertaining to their respective zones (in
ZENworks Configuration Management and ZENworks Linux Management) or Proxy DHCP
servers in their trees (in traditional ZENworks versions using Windows or NetWare imaging
servers). Because it is impossible to determine which Proxy DHCP server responds first (if
multiple Proxy DHCP servers respond), or which server's response is used by the device, it is
impossible to ensure that each PXE device contacts servers in its home zone or tree.
Server Referral Lists: For a ZENworks environment that has PXE services, the Server
Referral List configuration section provides a method for getting PXE devices to connect with
their proper imaging servers. Server referral lists are only used by PXE devices, and in
ZENworks Configuration Management only one Management Zone needs to have an active
Proxy DHCP server and server referral list. Because you can only have one referral list active
running on the device where you are running
