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 [WayBackbutton tags:

  • content of the th tag
  • content of the value attribute of the button tag having a type="submit" attribute and name=start attribute

So before starting to work on it, I created [WayBackIn 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 [WayBackHTMLParser — Simple HTML and XHTML parser that ships with the [WayBackPython 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.
    • The buttonis only relevant if it has type="submit" and name="start" and a value attribute in that order.
    • Output is in data which is an array of key/value pairs.

UptimeRobot is written in PHP and runs on IIS

Posted by jpluimers on 2018/11/28

In [WayBackJeroen 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:

More observations likely to follow.

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 [WayBackCategory: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:
    1. Login to your Fritz!Box
    2. Manually copy any of the URLs in the left side
    3. 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.ishttps://avm.de/fileadmin/user_upload/Global/Service/Schnittstellen/AVM_Technical_Note_-_Session_ID.pdf

Here is the list:

Protected Branches | GitLab

Posted by jpluimers on 2018/11/26

[WayBack] Protected Branches | GitLab usually are a cool feature, but sometimes they get in the way, for instance when someone having enough rights has pushed credentials or API keys to a repository.

Unlike the picture in the documentation that indicates the default looks like Masters, this is now assigned to the role Maintainers.

The tragedy of FireWire: Collaborative tech torpedoed by corporations | Ars Technica

Posted by jpluimers on 2018/11/26

Another piece of history: FireWire also known as IEEE-1394 [WayBack].

[WayBackThe tragedy of FireWire: Collaborative tech torpedoed by corporations | Ars Technica

I still have that iPod, cables and IEEE-1394 adapters to communicate with it (:

It didn’t help that by now various types of connections – including FireWire, USB and others –  are also used for DMA hacking. One less connection type, one less risk of entry:

A 90-byte “whereis” program – The Old New Thing

Posted by jpluimers on 2018/11/23

I needed a “get only the first result” of WHERE (which is present after Windows 2000, so XP, Server 2003 and up), so based on [WayBackA 90-byte “whereis” program – The Old New Thing I came up with this:

@echo off
:: based on https://blogs.msdn.microsoft.com/oldnewthing/20050120-00/?p=36653
::for %%f in (%1) do @echo.%%~$PATH:f
for %%e in (%PATHEXT%) do @for %%i in (%1 %~n1%%e) do (
  @if NOT "%%~$PATH:i"=="" (
    echo %%~$PATH:i
    goto :eof
  )
)
:: note: WHERE lists all occurrences of a file on the PATH in PATH order
goto :eof

Two changes:

  • it takes into account the extension if you specify it (unlike WHERE.EXE)
  • it bails out at the first match (like WHERE.EXE)
