Hi,
The gtk interface for simple-netaid -that I've had abandoned for a long time- will be released in a few days. The code is available here:
https://git.devuan.org/aitor_czr/simple-netaid-gtk/src/branch/master/ui
On the other hand, the ubus handlers in the daemon of simple-netaid have been improved as well, and actually snetaid works in combination
with dhcpcd as opposed to old versions that worked with the deprecated isc-dhcp-client.
In regard to a recent thread in DNG mentioning a bug related to dhcpcd working with runit as PID1, it's worth to say that the recommended
dhcpcd configuration for simple-netaid is to leave the former normally downed (not daemonized) but working on request of simple-netaid.
The latter will do the job during the boot process, being the responsible for the automatically connection attempts, even in cases of wifi
usb adapters.
Cheers,
Aitor.
