NAME

comitup – Manage wifi connections on headless, unconnected systems

SYNOPSIS

comitup [options]

DESCRIPTION

The comitup service provides a means to establish a connection between a computer and a wifi access point, in the case where wifi is the only means available to access the computer.

On startup, the service will attempt to connect to wifi using established networkmanager(8) connections. If this is not successful, comitup will establish a wifi hotspot with the name comitup-<nnn>, where <nnn> is a persistent number.

While the hotspot is active, a comitup-web(8) service is available to manage connecting to an access point. A captive portal environment is established to aid in discovery of the web service.

If two wifi interfaces are available, the hotspot will remain active on the first interface, and the internet connection will be made on the second. Otherwise, the hotspot will be replaced with the internet connection.

In all states, avahi-daemon(8) is used to publish the mdns host name comitup-<nnn>.local, making the web service accessible as e.g. http://comitup-123.local, for systems supporting Zeroconf. For other systems, a comitup Workstation entry is published which is visible to Zeroconf browsing applications, allowing the IP address to be manually determined. The web service address is http://10.41.0.1.

comitup logs to /var/log/comitup.log.
