MiniVend 3.11 supports CyberCash 3 with the CCMckDirectLib3_2.pm CCMckLib3_2.pm modules. If those modules are in place in your Perl include path (you can use VendRoot/lib as a home if you wish), using CyberCash 3.2 is the same as with CyberCash 2 server except:
CyberCash 3 maintains a configuration file (merchant.conf) for each merchant. This needs to be set in the variable CYBER_CONFIGFILE as in:
Variable CYBER_CONFIGFILE /home/you/mck-lib/conf/merchant.conf
In all likelihood, this will make the values of CYBER_HOST, CYBER_PORT, and CYBER_SECRET moot. It will not hurt anything if they remain set.
The variables CYBER_VERSION needs to be set to a numeric value of 3 or greater:
Variable CYBER_VERSION 3.2
This allows CyberCash 2 and 3 implementations to coexist on the same machine.
