During the installation, Hybrid Access Gateway installs the OpenSSH server for communication from outside. A Postgres database is installed and only used for local communication. Connections from outside are disabled by default.
During the installation, the default firewall of Ubuntu is applied. Only features that comes by default with the corresponding Ubuntu base image (currently 14.04) are available within the Hybrid Access Gateway appliance, including:
- Simple Network Management Protocol (SNMP)
SNMP is configured to send information related to its services and system health. However, by default it does not send information to any location as it does not know who the recipient would be. For this, the customer needs to un-comment the trapsess
command in the file /etc/snmp/snmpd.conf and point it to their SNMP manager to start sending information. - Network Time Protocol (NTP)
NTP is installed but no NTP server is connected automatically. This needs to be done by the customer over the VM wizard.
If Hybrid Access Gateway is configured to use an external database for users, reporting and OATH, the internal Postgres database service can be turned off without any hassle.
