HBOX_WEB_HOST examples

Section titled “HBOX_WEB_HOST examples”
ValueNotes
0.0.0.0Visible all interfaces (default behaviour)
127.0.0.1Only visible on same host
100.64.0.1Only visible on a specific interface (e.g., VPN in a VPS).
unix?path=/run/homebox.sockListen on unix socket at specified path
sysd?name=homebox.socketListen on systemd socket

For unix and systemd socket address syntax and available options, see the anyhttp address-syntax documentation.

Private network example

Section titled “Private network example”

Below example starts homebox in an isolated network. The process cannot make any external requests (including check for newer release) and thus more secure.

Terminal window
❯ sudo systemd-run --property=PrivateNetwork=yes --uid $UID --pty --same-dir --wait --collect homebox --web-host "unix?path=/run/user/$UID/homebox.sock"
Running as unit: run-p74482-i74483.service

Systemd socket example

Section titled “Systemd socket example”

In the example below, Homebox listens on a systemd socket securely so that only the webserver (Caddy) can access it. Other processes/containers on the host cannot connect to Homebox directly, bypassing the webserver.

File: homebox.socket

/usr/local/lib/systemd/system/homebox.socket
[Unit]
Description=Homebox socket


[Socket]
ListenStream=/run/homebox.sock
SocketGroup=caddy
SocketMode=0660


[Install]

File: homebox.service

/usr/local/lib/systemd/system/homebox.service
