The client program communicates with the database via TCP port 5432 and via port 8180 for the report generator. In order to allow for such communication, this port has to be open towards the database server. For projects where Nosyko's server is utilised, this means that any firewalls have to allow outgoing TCP traffic on port 5432 (for database traffic) and port 8180 (for reports and file uploading) against db2.nosyko.no (195.159.92.252). Some projects have their own servers and traffic has to be permitted to the server specified by the user upon log in. Traffic to the database server is channelled via SSL.
