2017-03-10 Keeping an eye on planes in the air
I usually keep dump1090 running on a raspberry pi. It seems it is quite easy to share the data from dump1090 with Plane Finder so I decided to give that a try. With the installation instructions via the Share your data with Plane Finder page I had the software installed easily. But I needed to visit the configuration page of the software via IPv4... while I disabled IPv4 on the raspberry so it took some changes to make it work again. Next thing the software was reporting the data was available fine but not uploading to the Plane Finder server. Checking with strace shows that the software tries to upload via an IPv4-only connection which will not work. Temporary re-enabling IPv4 fixes things, so it's purely an IPv4/IPv6 thing.
