===== Description =====
This script tracks licenses in use for each SafeNet Sentinel Protection Server key, optionally graphing. For example, [[http://www.liscad.com/liscad/|LISCAD]] ([[http://www.leica-geosystems.com/en/Leica-LISCAD_4851.htm|Leica]]), [[http://www.leica-geosystems.com/en/Leica-Geo-Office_4611.htm|Leica Geo Office]], [[http://www.gtstrudl.gatech.edu/|GT STRUDL]]. It'll also show whether ESRI floating licensing is active, as ESRI uses SuperPro keys, but that isn't as useful.

===== Installation =====
=== Client side ===
  * If you haven't already, install the Sentinel Protection Server.
  * Note the port used by the Sentinel Protection Server (defaults to 6002). Make sure you can bring it up in a web page (e.g. http://example.com:6002/) and confirm that it invokes some Java. If you aren't sure what the port is, you can check within Microsoft Windows:
    - Run ''C:\Program Files\Common Files\SafeNet Sentinel\Sentinel Protection Server\loadserv.exe''
    - Press the "Configure..." pushbutton.
    - Check the Http Port.
  * On the resulting web page, note the Serial Numbers, and determine what each key protects.

=== Server side ===
Edit $BBHOME/etc/bb-hosts, adding a ''sentinel'' tag to the appropriate lines, with optional http port and/or key descriptions (used in status and optional graphing). Use the following syntax:

  * sentinel[://port//][,//hexval//=//name//[,//hexval//=//name//]...]

For example:
     sentinel:6102
     sentinel,3573=Master,0045=Slave

Copy sentinel.sh (below) to your $BBHOME/ext and make sure it's executable.

Add the following (or similar) to $BBHOME/etc/hobbitlaunch.cfg<code>
[sentinel]
        NEEDS hobbitd
        CMD /home/hobbit/server/ext/sentinel.sh
        LOGFILE $BBSERVERLOGS/sentinel.log
        INTERVAL 5m
</code>

# This script checks the Sentinel License Monitor on hosts
# and reports each key's usage and details.
# In your bb-hosts file, use the following syntax:
#	sentinel[:port][,hexval=name[,hexval=name...]]
# Where port is the port for your Sentinel License Monitor (default 6002),
#       hexval is 4 digits corresponding to the serial number, name is whatever.
# For example:
#  0.0.0.0 example1 # sentinel
#  0.0.0.0 examplep # sentinel:6202
#  0.0.0.0 examplen # sentinel,3573=Master,0045=Slave
# Note: this has only been tested with SuperPro keys.
#
# Requirements:
#  wget and printf must be available. 

# Notes:
#  For some keys, the detail columns should be (7.3.2):
#    IP Address    User Name    Log Time    Client PID    LicenseID
#  But this always uses the same method: (7.4.2):
#    Client/Access Mode    User Name    Client login time    Client PID
#
# This uses the machine name, and not the IP address, when checking.

===== Known  Bugs and Issues =====
  * As noted in the source code, this depends on timing between checking licenseinfo.html followed immediately by licenseinfo.xml. So try to avoid having two servers requesting these simultaneously.
  * The licenseinfo.xml doesn't seem very reliable. Possibly due to the above, possibly due to other circumstances.
  * It has only been tested with SuperPro keys.

===== To Do =====
  * Discover a method for querying other than checking XML over HTTP results. Yes, there is a usage log file, but parsing that seems likely to require storing state information.

===== Credits =====
I wish I could give credit to someone else for determining the licenseinfo details, but I had to discover it on my own.

===== Changelog =====

  * **2010-02-25**
    * Initial release
