Inspired by https://at.hackerspace.pl/, hacked together in 30 minutes by q3k.
Install python, python-requests, python-mysqldb.
If you want a fancy HTML UI, copy the content of dist/ somewhere, it will access /at.json via AJAX.
Just run at.py. It will download a leasefile from the router and output an at.json at perpetuum. Serve this with a static file server or push it somewhere.
If you want the script to scp the resulting report for you, run it with the destination scp string as its' argument, ie. python2 at.py torvalds@example.com:/var/www/examples.com/.
