I can see the dll listed
I’m using the rpm package duplicati-2.1.0.111_canary_2025-03-15-linux-x64-cli.rpm and confirm on installation it overwrite the duplicati file in /etc/sysconfig so I have to copy the customised pone back manually. I get the feeling this may have been happening for a few releases as I do remember seeing the warning for service saying that the database was not encrypted, and .110 does the same.
When I start the service it shows this as the webservice status:
Mar 19 09:34:58 maggie.mydomain.com systemd[1]: Started duplicati.service - Duplicati web-server.
Mar 19 09:34:59 maggie.mydomain.com duplicati-server[104962]: Server has started and is listening on *, port 8200
And this is all it shows as listening on port 8200:
[root@maggie ~]# netstat -tunlp | grep -i duplicati
tcp6 0 0 :::8200 :::* LISTEN 104962/duplicati-se
