qaul-hubd Daemon

This is a multi purpose router and database daemon for It handles network driver and user state as a detached process, and allows both http and unix ipc clients to connect to it.

It doesn't come with it's own user interface, which means you will have to build one separately and configure it to connect to your qaul-hubd instance.

Because all networking is done in userspace, no root access is required.


In order for qaul-hubd to work properly it will have to run in the background to handle incoming and outgoing network connections. It's recommended to launch it via a user systemd unit.

[Unit] hub daemon

ExecStart=$HOME/bin/qaul-hubd <your parameters here>

Save this file in ~/.local/share/systemd/user/

Now you can reload the daemon and start the unit.

$ systemctl daemon-reload --user
$ systemctl enable --user qaul-hubd.service
$ systemctl start --user qaul-hubd.service

Available configuration

Following is a list of qaul-hubd configuration values. Those marked with a * are mandatory. Commandline arguments take precedence over environment variables.

HUBD_UDP_DISCOVERY=0--no-udp-discoverPrevent qaul-hubd from registering a multicast address to find other clients on the same network. Some networks may forbid this, or cause performance issues.
HUBD_SETUP_UPNP=0--no-upnpDisable automatic UPNP port forwarding. Some networks may forbid this, or cause performance issues.
HUBD_RUN_MODE=[MODE]-m / --mode [MODE]Specify the peering mode of this hub. Possible values: "static", "dynamic"
