By default, inca components use ssl to communicate with each other. Credentials are automatically generated with the "bin/inca createauth" command described in step 4 of the quickstart guide. The createauth command creates keys and certificates for each inca component (the agent, depot, consumer and incat) and stores them in the $INCA_DIST/etc directory.
Inca can also be run without ssl communication (credentials then do not need to be created with the "createauth" command). To turn off ssl communication, edit the $INCA_DIST/etc/common/inca.properties file as follows:
replace all instances of "incas" with "inca"
change these lines to turn authentication off:
9 # To turn authentication (i.e., SSL communication) off and on 10 inca.agent.auth=false 11 #inca.agent.auth=true ... 67 # To turn authentication (i.e., SSL communication) off and on 68 inca.depot.auth=false 69 #inca.depot.auth=true ... 110 # To turn authentication (i.e., SSL communication) off and on 111 inca.consumer.auth=false 112 #inca.consumer.auth=true
