I totally forgot it was possible to usie an old Fritz!Box to act as a DECT repeater:
Um die Abdeckung von DECT für mobile Festnetztelefone zu verbessern, lässt sich eine ältere Fritzbox verwenden.

Via [WayBack] Knowledge Base | AVM International:
3 Setting the maximum transmitter power
- Click “Wireless” (“WLAN”) in the FRITZ!Box user interface.
- Click “Radio Channel” in the “Wireless” (“WLAN”) menu.
- If the option “Set radio channel settings automatically (recommended)” is enabled, proceed with the following section.
- If the option “Adjust radio channel settings” is enabled:
- Click “Additional settings”.
- Select “100%” from the drop-down list “Maximum transmitter power”.
- Click “Apply” to save the settings.
Hence the settings below: 6% Maximum transmit power is the lowest I could set.
For devices that cannot adjust their antenna output power which have RP-SMA connectors, I bought these to effectively throttle them:

I have a bunch of [WayBack] FRITZ!WLAN Repeater 1750E | Overview | AVM International devices; this is the quickest way to install them as LAN -> WiFi bridge (connect ethernet to your LAN; use the WiFi as a bridge).

I forgot to document this earlier.
Many Fritz!Box devices cannot be upgraded to recent firmwares. The behaviour differs on hardware revisions of the same model. I’ve seen it happen on Fritz!Box 7360 devices, but others are could be affected too.
You can get the firmware revision using the trick here: FRITZ!Box call http://fritz.box/cgi-bin/system_status.
If your hardware revision is affected, do not expose it to the outside world.
You could still turn it into a local switch though: [WayBack] Convert FRITZ!Box 7360 to Managed Switch (or even Access Point) having it’s own IP address: Setting up the FRITZ!Box as an IP client.
I did this before even discovering about the hardware revision limits as I wanted to keep the full phone history when migrating from ADSL to fiber (which came with a brand new Fritz!Box 7490) and could use the extra LAN ports.

Was working to get fritzcap to emit a list of interfaces so I could specify which one to capture.
For that I needed to parse the output of http://fritz.box/capture.lua which consists of HTML fragments like below.
What I needed was for each consecutive entries of [WayBack] th and first [WayBack] button tags:
th tagvalue attribute of the button tag having a type="submit" attribute and name=start attributeSo before starting to work on it, I created [WayBack] In order to fix #5, print a list of available interfaces to potentially capture from · Issue #6 · jpluimers/fritzcap
The goal was to get a series of key/value pairs:
4-138 = AP2 (2.4 + 5 GHz, ath1) - Interface 1
4-137 = AP2 (2.4 + 5 GHz, ath1) - Interface 0
4-132 = AP (2.4 GHz, ath0) - Interface 1
4-131 = AP (2.4 GHz, ath0) - Interface 0
4-129 = HW (2.4 GHz, wifi0) - Interface 0
4-128 = WLAN Management Traffic - Interface 0a
So I built a class descending from [WayBack] HTMLParser — Simple HTML and XHTML parser that ships with the [WayBack] Python standard libraries.
If in the future I need more complex HTML parsing, then these links will help me choosing more feature rich parsers:
Back to the HTMLParser descendant in interfaces_dumper.py which can basically be condensed down to the code below.
handle_data is called for both start tags and end tags. The th value in data is only present in the start tag (at the time of end tag the data is empty), so you need to keep track of both last_start_tag and last_end_tag.handle_endtag maintains last_end_tag to help handle_data.handle_starttag maintains last_start_tag to help handle_data and also handles the button behaviour.
buttonis only relevant if it has type="submit" and name="start" and a value attribute in that order.data which is an array of key/value pairs.Posted in Development, Fritz!, Fritz!Box, fritzcap, Internet, Power User, Python, Scripting, Software Development | Leave a Comment »
