Can we reference here all the ports that you would expect being used by odoo and shortly explain the purpose of each one?

E.g. I've seen references to xmlrpc_port which by default is set to 8069 in openerp/tools.config.py and can be changed in odoo server config file

I've also seen references to xmlrpcs_port, netrpc_port, netrpcs_port but I'd like to know which port is actually used in each case and with what purpose.
