9	      SSI Node-Locked Licensing	Notes
9			 (General)

9

The following describes	 how  to  enable  SSI  software	 for
node-locked licensing. Graphics	produced by the	software may
be displayed remotely using X Windows, but the software	will
be  constrained	 to  run on the	cpu of the licensed host. If
you need floating licensing, please see	 the  "SSI  Floating
License	Manager	Installation Notes".

For the	purpose	of demonstration,  this	 document  describes
how to enable SimWave.	The same steps may be used to enable
other SSI software packages; simply substitute the  name  of
the  desired package for the string, "wav", in the following
instructions.


Create a "/usr/ssi" directory if it doesn't  already  exist,
and following the instructions in the user's manual, install
the software.  You will	need to	create a soft  link  in	 the
"/usr/ssi"  directory which points to the actual location of
the software.  For  example,  if  SimWave  is  installed  in
"/usr/cad/wav2.3I.1", use this command:

	ln  -s	/usr/cad/wav2.3I.1  /usr/ssi/wav


Set the	permissions for	the links  so  that  all  users	 can
access the software:

	chmod  a+rx  /usr/ssi/wav


The directory "/usr/ssi" is also needed	for the	SSI software
licensing  system,  so do not modify it	in any way after the

software enabling has been completed.  The software  protec-
tion should now	be enabled.


1.  Enabling


Go to the "/usr/ssi/wav" directory and execute	the  command
"BIN/enable"   while  logged  in  as  superuser/root.	When
prompted, choose the "initialize" mode.	 This  first  execu-
tion  of  BIN/enable  will  initialize the software and	will
create a hexadecimal file named	"PINIT".

Either FAX the PINIT file to Systems  Science-Customer	Ser-
vice at	(415) 812-1820 or, following the instructions in the
next section, e-mail the PINIT to enable@systems.com.

Systems	Science	will return to you  a  validation  password.
Go to the "/usr/ssi/wav" directory and put the password	in a
file named "PASS.OUT".	Be sure	to enter all "0's" as  zeros
and  not  as  upper  case  "O's".   Then, while	logged in as
superuser/root,	run BIN/enable again, but this	time  choose
the "validate" mode.  This will	enable SimWave to execute on
the licensed machine.  Do not execute  "BIN/enable"  in	 the
initialize  mode  a  second  time or you will need to obtain
another	password.


1.1.  Enabling Via e-mail


Validation passwords can be retrieved by e-mailing the PINIT
file  to  enable@systems.com.  Your e-mail must	be formatted
exactly	as follows:



	END USER: John Doe, Super Systems, Central CAD
	PINIT:
	a7b4  a7e5  9e18  293b
	5d5d  81cb  6c4b  d1



Please make sure to include your name,	company,  and  divi-
sion.  Make  sure the PINIT code follows the "PINIT:" header
line.

The "enable" login will	mail back to you a validation  pass-
word  and  a "reference" number. The reference number can be
used later to extend the enabling or to	get a permanent	ena-
bling.

To extend a license beyond the	initial	 evaluation  period,

you  must send Systems Science a request. The request should
include	your workstation's hostid and a	copy of	 a  purchase
order  or  other  reason for the extension.  If	your request
for extending the enabling is  accepted,  you  may  use	 the
reference  number  to  get  a  new validation password.	 The
validation password may	be retrieved by	e-mailing the refer-
ence  number to	enable@systems.com. Your e-mail	must be	for-
matted exactly as follows:


	END USER: John Doe
	REFERENCE: 2345



If for some reason you cannot find the reference, or for any
other  reason you cannot get an	extension, you can re-enable
from scratch (enable in	the initialize mode).

2.  Customer Support


If you have any	problems, send e-mail to support@systems.com
or call	Systems	Science-Customer Support at (415) 812-1800.

3.  Re-installation and	Upgrades:


All the	enabling files reside in a directory  with  a  blank
name,  within  /usr/ssi. If those files	are removed, copied,
or touched, the	software is disabled. However, the  software
package	 itself, can be	re-installed or	upgraded without any
effect on the enabling.	 Changes in  version  numbers,	i.e.
wav1.0	to  wav1.1,  require  re-enabling.   Changes in	sub-
versions, i.e. wav1.0B to wav1.0C, and do  not	require	 re-
enabling (just install the new software	and it will continue
to be enabled).
