The AVM FRITZ!Box (FB) routers have a feature to allow Internet access to specific devices only for a certain amount of time. If that time is exceeded then the owner can print Internet Tickets that allow another 45 minutes of surfing.
The code in this repo helps to automate the retrieval and distribution of such Internet tickets.
There is also a GCP Pub/Sub based service to print tickets from remote. This is not well documented, ask me if you want to use that.
As of Version 22 (2020-08-27) this works with Fritz!OS 7.20 and has not been tested if it still works with older versions. Feedback is welcome.
The fritzbox-get-internet-tickets.py program will connect to the FB, retrieve the 10 available Internet tickets via web scraping (there is no API for that) and print them as a list to STDOUT.
Set the password via the FRITZBOX_PASSWORD environment variable and check the code for more options.
This program is usually not used directly, unless you plan to distribute the tickets yourself.
The fritzbox-internet-ticket program is the main program and will first retrieve the tickets from the FB and then send the first ticket to a print queue. This program also has a Desktop starter called "Print Internet Ticket".
Optionally it will upload the remaining 9 Internet tickets to a Google form for further processing. To enable this feature set the FRITZBOX_GOOGLE_FORM_ID and FRITZBOX_GOOGLE_FORM_ENTRY_ID variables to suitable values (get the values from a prefilled link to your form. The form should simply contain one text entry field).
All configuration parameters are stored in /etc/fritzbox-internet-ticket.conf like this:
FRITZBOX_PASSWORD=mySuperSecretPasswort
FRITZBOX_PRINT_QUEUE=Zebra
FRITZBOX_GOOGLE_FORM_ID=1FAIpQLSfhbfiefhb437ghffsUW-WULIAkPL_J-RtJN_Kiu4Fhjdwshgw
FRITZBOX_GOOGLE_FORM_ENTRY_ID=1598434206Take care to protect this file with file system permissions if you are on a multi user system.
