License.txt
The license.txt file contains the software license key needed to unlock HSYCO. The first time HSYCO is started, or in case this file is removed before start, HSYCO creates a new file containing the encrypted code that univocally identifies the hardware where the software runs. In order to allow the correct execution of HSYCO the file should contain the software license key, issued by HSYCO Srl specific to every single computer.
The hardware identification code is based on the hardware components installed on the server. For example, by replacing or adding network cards the code changes and therefore the software license key will be no longer valid for the new configuration.
If the license key is not in the file, or if it is not correct, HSYCO disables all the access functions to the field devices, keeping only the Web Server working. It will be therefore possible to access the Web pages, but not to execute any action on or interface to the systems connected to HSYCO.
The possible error messages related to the software license are written in the daily log files.
The content of license.txt, generated by HSYCO and containing only the hardware identification code is the following:
#Generated by HSYCO CONTROLLER 3.3.0
#Tue Dec 10 11:49:06 CET 2013
hwid=2080334b6283f450283bd4bbc3389bf66dc03dda
To unlock HSYCO features, replace the license.txt file generated by HSYCO at the time of its first execution with the license.txt version with the key provided by HSYCO Srl. The file and the key are automatically recognized within a few seconds, it is therefore not necessary to restart HSYCO.
This is an example of the complete software license key file:
