021 April 2021, cirrid ona.im DNS shim for OSX and Linux.

download the binary for your OS, make it executable, and then install

chmod 755 ./cirrid
sudo ./cirrid install

the service will be installed to run as root on Linux and OSX, and will auto start.

it will

• add DNS resolution for $(hostname).ona.im and *.$(hostname).ona.im to point to a virtual IP address, so it works when you don't have internet access.
• set up an ipaddress alias so the virtual IP address works.
• flush the local DNS cache (on Ubuntu it seems to avoid caching, which is nice.)

TODO: get the STACKDOMAIN from the cirri container - the hard thing is that its necessary to watch for Docker starting, and to re-check regularly...

NOTE: don't use dig on OSX - it doesn't obey the same dns resolution rules as the rest of OSX
