how can I free up space on /boot as “openSUSE-2014-462” fails to install on openSUSE 12.3 x86_64
Posted by jpluimers on 2018/11/30
From a long time ago:
[WayBack] how can I free up space on /boot as “openSUSE-2014-462” fails to install on openSUSE 12.3 (x86_64):
Installation of kernel-desktop-3.7.10-1.40.1 failed: (with --nodeps --force) Error: Subprocess failed. Error: RPM failed: installing package kernel-desktop-3.7.10-1.40.1.x86_64 needs 16MB on the /boot filesystem
Based on that thread, I figured out the steps:

Not all Fritz!Box devices can be upgraded to the most recent firmware
Posted by jpluimers on 2018/11/30
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.
Fritz!Box 7360 hardware revision v1: limited to firmware 06.3x

I might give a few of these a shot:

Parsing simple html in Python
Posted by jpluimers on 2018/11/29
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:
- content of the
thtag - content of the
valueattribute of thebuttontag having atype="submit"attribute andname=startattribute
So 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:
- [WayBack] Python HTML Parser Performance
- [WayBack] HTML Scraping — The Hitchhiker’s Guide to Python
- [WayBack] Parsing HTML using Python – Stack Overflow
Back to the HTMLParser descendant in interfaces_dumper.py which can basically be condensed down to the code below.
handle_datais called for both start tags and end tags. Thethvalue indatais only present in the start tag (at the time of end tag thedatais empty), so you need to keep track of bothlast_start_tagandlast_end_tag.handle_endtagmaintainslast_end_tagto helphandle_data.handle_starttagmaintainslast_start_tagto helphandle_dataand also handles thebuttonbehaviour.- The
buttonis only relevant if it hastype="submit"andname="start"and avalueattribute in that order. - Output is in
datawhich is an array ofkey/valuepairs.

UptimeRobot is written in PHP and runs on IIS
Posted by jpluimers on 2018/11/28
In [WayBack] Jeroen Pluimers @jpluimers: Every now and then editing @uptimerobot entries failed. Just “HTTP Error 503.4 – Service Unavailable The FastCGI pool queue is full” 1/2 I found out that UptimeRobot:
There is also a maintenance page at uptimerobot.com/maintenance.php#tvMode [Archive.is] and uptimerobot.com/maintenance.php?c-e [Archive.is]. If you get to those, then retry in ~10 minutes as sometimes it takes that long for an update to be processed.
Sometimes setting up multiple Android devices for the same uptimerobot account can be a bit of a hassle: [WayBack] Uptime Robot on Twitter: “Once logged in to the account from another Andriod device, that device will be added as an alert contact too.… “.
All in all it is still a nice tool (:

A few observations on Python while I made my first steps into it
Posted by jpluimers on 2018/11/28
A while back, I made my first steps into Python.
Coming from a mixed language back-ground (including Pascal, Delphi, C#, SQL, batch files, PowerShell, bash, C, Java) it was an interesting experience.
A few observations:
- It’s a [WayBack] line oriented language.
- I secretly think that’s the reason there are no multi-line comments in Python, but Guido never gave a reason, just that you can use multi-line “”” or ”’ strings for them: [WayBack] Why doesn’t Python have multiline comments? – Stack Overflow
- Multi-line strings can end up in generated documentation or mess with your indenting. So putting a comment # octothorp in front of each line is recommended. [WayBack] Comment out a Python code block – Stack Overflow
- Most code editors have a shortcut for multi-line comments. Atom.io has Ctrl-/ for it. [WayBack] Commenting out code blocks in Atom – Stack Overflow
- The
passstatement is your [WayBack] no-op friend (via [WayBack] What’s a standard way to do a no-op in python? – Stack Overflow). - Though Python supports the subclass-the-Thread class for multi-threading [WayBack] multithreading – Stopping a python thread running an Infinite Loop – Stack Overflow
- The idiom however seems to wrap the thread into a function instead of [WayBack] multithreading – Overriding python threading.Thread.run() – Stack Overflow
- Though the built-in data type
boolis lower-case, theFalseandTruebuilt-in constants start with a capital [WayBack] 4. Built-in Constants — Python 2.7.13 documentation - Lots of idioms are centered around key/value or name/value pairs.
- It has two ways of formatting/aligning strings, which is OK as I hate re-inventing wheels [WayBack] Python spacing and aligning strings – Stack Overflow and [WayBack] 5. Built-in Types — String Formatting Operations
- There is a huge number of [WayBack] Python standard libraries.
More observations likely to follow.

web servers and pre-compressed content
Posted by jpluimers on 2018/11/27
One of my sites is about a lot of static content which is mostly generated too. So I want to put some research into pre-compressing that content before serving it.

Fritz!Box LUA links on my research list
Posted by jpluimers on 2018/11/27
I’m not sure around which firmware versions Fritz!Box started to implement LUA links, but they are now on my research list.
Below a reference and where I found them.
A few notes first:
- There are many duplicates, which in due time I need to de-duplicate.
- The .lua links seem to override the old cgi-bin links (that are partially reverse engineered at [WayBack] Category:Befehle in /usr/www/cgi-bin – Fritz!Box).
- Usually, .lua links require a SID. In the web-ui, a Fritz!Box very much tries to hide that SID from URLs in the browser address bar (especially for firmware versions 06.50 and up) so the easiest to get them is this:
- Login to your Fritz!Box
- Manually copy any of the URLs in the left side
- Take the SID from there.
- More recent firmware versions hide the .lua links too, but you can see them when monitoring your network traffic in the developer mode of your web browser
Logging in programmatically needs a challenge response mechanism. It used to be at [Wayback] http://www.avm.de/de/Extern/Technical_Note_Session_ID.pdf but now has moved to [Wayback/Archive.is] https://avm.de/fileadmin/user_upload/Global/Service/Schnittstellen/AVM_Technical_Note_-_Session_ID.pdf
Here is the list:
