 Tivoli Management Environment (TME 10) Lightweight Client Framework (LCF)* 

				   for

                           Novell NetWare 4.1x*

---------------------------------------------------------------



TME 10 LCF is a lightweight client framework which allows limited invocation

of methods within the Tivoli Framework.  LCF consists of the LCFd NLM (a long

running Unix-like daemon) and the LCF software development kit (a collection

of libraries and headers for development of LCF methods).



LCF DAEMON (LCFd): 

 

1. AUTO LAUNCHING 



LCFd has been installed on your NetWare server. To complete the install,

you must call the lcf.ncf file from your autoexec.ncf file. Doing this

will allow LCFd to auto launch each time the server is re-started.

You will find the lcf.ncf file in the SYSTEM directory on the

server. To launch LCFd, run the lcf.ncf file. The lcf.ncf file loads

the lcfutils.nlm library, then loads lcfd.nlm.



NOTE: When lcfutils.nlm launches (netware 4.x only), the default context and tree

is stored for use by the LCF system.  To change this, edit the lcf.sys file in the

SYSTEM directory and modify the NWDS_CONTEXT and NWDS_TREE entries to reflect

your change. Additionally, you can reset these values by manually removing the lcf.sys

file from the SYSTEM directory, then re-running the SETUP program. 



LCFd will launch with the the default configuration. To launch LCFd with 

a custom configuration, you may use command line switches or a launch 

configuration file. See the section entitled 'CUSTOMIZING LCFd' for more

details.



The first time LCFd launches it must perform an initial login.  By default,

LCFd transmits UDP broadcast packets on port 9494 in order to locate a gateway

on the current subnet.  If you configure your gateway on the current subnet to

utilize a port other than 9494, use the -p option when launching LCFd for the

first time.  (i.e. If your gateway port is 1344, use the syntax; 'lcfd -p 1344')

Once an initial login occurs, it is not necessary to use the -p option.

LCFd on subsequent logins will direct connect to the gateway into which it

initially logged.



For initial deployments, it is recommended that a single gateway be deployed per

subnet. There is no limit to the number of LCFd's that can subscribe (or belong)

to that gateway.  After analyzing network loading, you may decide to add additional

gateways to those subnets which have a dense concentration of LCFd's.  Important: If 

multiple gateways exist on the same subnet, each gateway must utilize a unique port 

on that  subnet.



Logging for the current Netware version of LCFd outputs to lcfd.log unless overridden 

on the command line or config file.  Log messages from LCFd are displayed on the LCFd

screen unless overridden on the command line or config file.  Log messages from methods

are not displayed on the LCFd screen.



2. CUSTOMIZING LCFd



LCFd may be customized by launching with command line switches.  The settings

established by these switches is stored in the cfgout.dat file for re-loading

on subsequent launches of LCFd.  To restore settings to the programatic

defaults, remove the cfgout.dat file before launching LCFd.



If no switches are utilized, LCFd uses the following programatic defaults:



	logfile = lcfd.log located in root of SYS volume

	config output file = cfgout.dat located in root of SYS volume

	config input file = searches for lcfd.cfg in root of SYS volume

	gateway and lcfd port = uses the encoded port in the lcf.dat file

	lcfd port = uses the gateway port 

	working directory = root of SYS volume

	

	

The following command line switches are available for LCFd:



       	-l log file

       	-d set debug (logging) verbosity

       	-c config file

       	-p gateway and lcfd port

       	-P lcfd port

       	-s start as console app on Windows NT

       	-i install lcfd as a service (Windows NT)

       	-r remove lcfd service (Windows NT)

       	-C working directory

	-D supports these keys and default values):

   		lcfd_port=9495

 		gateway_port=9494

   		bcast_addr=255

   		log_threshold=2

   		start_timeout=10

   		run_timeout=20

   		logfile=lcfd.log

   		config_path=lcfd.cfg

   		run_dir=.

   		cache_loc=cache

   		debug_flags=0

   		log_size=1024000

   		log_queue_size=5120

   		lcs.machine_name=mmcdaniels

   		lcs.machine_unique_id=<UNDEFINED MACHINE ID>

   		lcs.crypt_mode=0

   		lcs.crypt_key=

   		lcs.interp=w32-ix86

   		lcs.login_interfaces=

   		lcs.gateway_address=



Additionally, LCFd can be customized by setting keys in a configuration file

which can be read at launching of LCFd.  The following keys may be set in the

configuration file:



	lcfd_port

	gateway_port

	bcast_addr

	log_threshold

	start_timeout

	run_timeout

	logfile

	config_path

	run_dir

	cache_loc

	debug_flags

	log_queue_size

	log_size

	lcs.machine_name

	lcs.machine_unique_id

	lcs.crypt_mode

	lcs.crypt_key

	lcs.interp

	lcs.login_interfaces

	lcs.gateway_address



For more detailed information on configuration options, command line options,

and the operation of LCFd on NetWare, consult the 'Lightweight Client Framework 

User's Guide."

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.

  • Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.

  • From the Properties dialog box, select the Driver tab.

  • Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
