I'm pretty new to vOneCloud. I'm going to test the appliance to see if it fits our needs and we could build our cloud with it.
During the setup and first login I monitored the connections in our firewall log and saw that the appliance initiated some outgoing connections. I'm wondering for what reasons these connections are needed and if I could run the appliance in a restricted network segment without any internet access allowed.
So, could someone tell me something about the following connections?
At first I saw a lot NTP (udp/123) traffic. How could I configure the appliance to use my internal NTP servers? Am I right, that I have to login to the console and configure the settings in /etc/ntp.conf or /etc/chrony.conf? Or will changes in these files be overwritten when updating the appliance?
Second I saw HTTPS connections to the IP 126.96.36.199 which seems to belong to securitycheck.phusionpassenger.com which seems to be some kind of update check. Does anyone have some further information? Are these connections needed for proper operation?
Third thera are some HTTPS conenctions to IP 188.8.131.52 which belongs to li275-92.members.linode.com. The access happens when I'm clicking around in the WebUI. Same happens whith 184.108.40.206 alias li255-62.members.linode.com. Why is that? What is this external destination need for?
And last but not least when accessing Sunstone there was an outgoing HTTPS connections with destination 220.127.116.11. Does anyone know what this connection is used for?
Usually our systems are not allowed to access the internet except the access is a MUST HAVE needed for proper operation.
Thank your in advance for your ansers. Looking forward reading you, soon.
