I'm not sure what you mean by "console". The only interface to HG is via the web interface. You can access HG to control modules via an Android or Windows phone, but that does not give access to configuration.
If you are looking to do some debugging, you might need to see the Mono output. That can be done in Linux by stopping the HG process and launching it manually. Alternately, you can modify the /usr/local/bin/homegenie/startup.sh script to direct the output to a file. I would not recommend that be a permanent configuration as writing to flash memory regularly can reduce the life of the storage quickly.
