I’m new to duplicati and i have it installed in my headless UBUNTU server 18.04 machine.
I’m trying to set duplicaty to use https instead of the default http interface.
According to my research, i just need to create an SSL certificate in PKCS#12 format for duplicati to use and and indicate the location of such certificate in the file /etc/default/duplicati by adding the option --webservice-sslcertificatefile
The last sentence of that file in my system reads as follows:
# Additional options that are passed to the Daemon.
DAEMON_OPTS= "--webservice-interface=any --webservice-port=8200 --portable-mode --webservice-sslcertificatefile=/var/servercertificate/Cerberus.p12"
As expected, with these settings Duplicati successfully uses https and my ssl certificate.
However, after i did this, the fans on my server just went wild. I checked the running services with the “top” command and noticed that mono-seg had a cpu usage between 50-100% in one of the cores.
So, i went back and deleted the --webservice-sslcertificatefile. All of the sudden everything went back to normal but i lost the encrypted connection via https that I was pursuing.
I honestly don’t know if this is a bug or if this is supposed to work this way.
I also noticed that everyone using --webservice-sslcertificatefile was also using --server-mode instead of the default --portable-mode option. I don’t have a clue of the difference between these two options or if using --server-mode would solve the high cpu ussage.
Has anybody experienced the described behavior? Or am I the only one?
