[SOLVED] Installed Duplicati on PBS, can't reach it from outside the PBS.

[scrafi]

Hello,

I use PBS at home and would like to use Duplicati to upload the backups to Backblaze, but when I install duplicati on PBS it installs just fine and running a "wget 127.0.0.1:8200" shows me that the web service is accessible, but I can't reach it from outside PBS via pbs.local:8200 or using the IP.

Are there firewall rules I have to set to be able to access the web interface of duplicati?

I know this is most likely not officially supported and not considered, but any help would be appreciated!

Thanks!

Best regads,
Scrafi

Are you using Duplicati for public interface or only local? can you check for that by doing ss -t -a | grep LISTEN

Thanks for your help!

This is the output I get when I run the command:

It seems like 127.0.0.1:8200 should be *:8200 when I want to be able to access it outside of the pbs itself, I tried "opening" the port using iptables but I had no luck.

true, you need to set the 8220 port to the public interface you can check the below link [0] (I'm not sure if that will work because I don't use Duplicati)

Ah perfect, thank you!

I see now, normally you run duplicati like a program on a machine and only access it locally not like a server, so it doesn't have anything to-do with PBS itself.

For future reference, this is the command to start the service listening on a different ip/interface:

duplicati-server --webservice-port=8200 --webservice-interface=192.168.0.124

to make it permanent, you would have to edit the systemd service:

nano /lib/systemd/system/duplicati.service

[Unit]
Description=Duplicati web-server
After=network.target


[Service]
Nice=19
IOSchedulingClass=idle
EnvironmentFile=-/etc/default/duplicati
ExecStart=/usr/bin/duplicati-server --webservice-port=8200 --webservice-interface=192.168.0.124 $DAEMON_OPTS
Restart=always


[Install]
WantedBy=multi-user.target

systemctl daemon-reload
