Internet mode security- How do I know if internet mode is active

client
1

Hey,

I am currently testing out Urbackup. For that I have a sever (Ubuntu 24.04.3 LTS) and a client (also Ubuntu 24.04.3 LTS).

I installed the client via the Server Web UI (Add new Internet/active client) and followed the instructions there.

My/etc/default/urbackupclien file has following entry:

#If true client will not bind to any external network ports (either true or false)
INTERNET_ONLY=true

Does that mean the internet mode is active? How do I confirm it is active/the communication between client and server is encrypted?

Thank you very much,

Fred
