Factory reset a MikroTik hEX PoE RB960PGS using the reset button

Posted by jpluimers on 2021/08/02

Edit 20260504: added link to the gist of the switch configuration and a link to a forum post I recently found.

[WayBack] Manual:Reset – MikroTik Wiki:

 unplug the device from power

2) press and hold the button right after applying power

Note: hold the button for 5 seconds (USER LED will start flashing)

3) release the button to clear configuration.

Icon-note.png Note: If you wait until LED stops flashing, and only then release the button – this will instead launch Netinstall mode, to reinstall RouterOS.

Initial configuration

Listing information on all active interfaces on MacOS part 2: adding DHCP/BOOTP and routing details

Posted by jpluimers on 2021/07/27

This is a continuation of yesterdays

Listing information on all active interfaces on MacOS part 1: getting the active interface names.

It is based on ideas in these StackExchange posts:

I threw most of the implementation details in the ideas away, as they were way to much based on empirical trial and error, than proper research.

So I tried doing the research and came up with the things below.

Getting the IPv4 address and DHCP/BOOTP information of a NIC

By using the ipconfig command, you can get specific details for a NIC like an IPv4 (with the getifaddr) or DHCP (with the getpacket option to get the latest DHCP packet):

for i in $(ifconfig -l -u); do if ifconfig $i | grep -q "status: active" ; then echo $i; fi; done | xargs -n1 -I_nic_ sh -c 'echo "_nic_: $(ipconfig getifaddr _nic_)"'

or DHCP/BOOTP:

for i in $(ifconfig -l -u); do if ifconfig $i | grep -q "status: active" ; then echo $i; fi; done | xargs -n1 -I_nic_ sh -c 'echo "_nic_: $(ipconfig getpacket _nic_)"'

The latter returns a very long list, which I wanted to shorten into a more readable format.

ipconfig syntax

You can find more information in the [Archive.is] ipconfig(8) [osx man page] / [WayBack] ipconfig Man Page – macOS – SS64.com excerpt:

Did not realise that a 2018 Mikrotik vulnerability made it to the top of the CBL (SMTP composite black list) warning page for quite some months as the first ever device

Posted by jpluimers on 2021/07/02

Having it accidentally made it to the CBL (Composite Blocking List – Wikipedia) a long time ago, I discovered the page started with (WayBack link mine):

IMPORTANT: Many CBL/XBL listings are caused by a vulnerability in Mikrotik routers. If you have a Mikrotik router, please check out the [WayBack] Mikrotik blog on this subject and follow the instructions before attempting to remove your CBL listing.

It wasn’t one of my Mikrotik devices, as first of all they had all being patched out of the box from a really empty internal network before being externally exposed to the internet or more busy internal networks, and second because the CBL entry was a one off on one specific day where someone used our guest network.

Some CBL entries in the range where it was displayed, quite a while after CVE-2018-14847 became public:

GitHub – jjjake/internetarchive: A Python and Command-Line Interface to Archive.org

Posted by jpluimers on 2021/06/16

On my list of things to play with: [WayBack] GitHub – jjjake/internetarchive: A Python and Command-Line Interface to Archive.org.

Via:

Related:

  • [WayBack] The Internet Archive Python Library — Internet Archive item APIs 1.8.5 documentation
  • [WayBack] Command-Line Interface — Internet Archive item APIs 1.8.5 documentation
  • [WayBack] Quickstart — Internet Archive item APIs 1.8.5 documentation, including:

    Configuring

    Certain functionality of the internetarchive Python library requires your archive.org credentials. Your IA-S3 keys are required for uploading, searching, and modifying metadata, and your archive.org logged-in cookies are required for downloading access-restricted content and viewing your task history. To automatically create a config file with your archive.org credentials, you can use the ia command-line tool:

    $ ia configure
Enter your archive.org credentials below to configure 'ia'.

Email address: user@example.com
Password:

Config saved to: /home/user/.config/ia.ini

    Your config file will be saved to $HOME/.config/ia.ini, or $HOME/.ia if you do not have a .configdirectory in $HOME. Alternatively, you can specify your own path to save the config to via ia --config-file '~/.ia-custom-config' configure.

    If you have a netc file with your archive.org credentials in it, you can simply run ia configure --netrc. Note that Python’s netrc library does not currently support passphrases, or passwords with spaces in them, and therefore not currently suported here.

Check if this still happens: some Twitter content in the WayBack machine gets a slash in the URL removed during rendering on Chrome

Posted by jpluimers on 2021/06/11

From my research list; check if this still happens: [WayBack] Saving Twitter content in the WayBack archive: the fully loaded page has a wrong trailing URL (missing the second slash before the authority) · GitHub

  1. Visited https://twitter.com/MarkGraham
  2. Saved it using https://web.archive.org/save/https://twitter.com/MarkGraham
  3. Waited for the save to complete and the page to fully load and got https://web.archive.org/web/20190607081047/https:/twitter.com/MarkGraham
  4. Observed the trailing part is not a valid URL any more https:/twitter.com/MarkGraham: it is missing the second slash before the authority (see https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Generic_syntax)

This might be a Twitter.com thing:

Notes:

  • I have only tested this with my Chrome configurations on various machines (both regular and anonymous tabs) over at least a year; I need to figure out what happens when using different browsers.
  • It does not always happen.

Contact for when WayBack internet archival fails to grab content

Posted by jpluimers on 2021/06/07

For my link archive, some tweets. [WayBack] Mark Graham is the person to contact in case archiving a link in the WayBack machine fails.

These are the steps for my link archival:

  1. check if it saves and renders with the WayBack machine, if so, copy the saved URL and the original URL
  2. check if it saves and renders with archive.is, if so, copy the saved URL and the original URL
  3. if neither saved, then use the original URL and link text, but note it was unsavable; otherwise prepend the original URL and link text with [WayBack] or [Archive.is] containing the saved URL

Reminder to self: get less dependent on the various clouds

Posted by jpluimers on 2021/06/04

For my link archive: [WayBack] Grote Google-storing trof Gmail, YouTube en diensten van derden – IT Pro – Nieuws – Tweakers.

It has some interesting tips for IoT video doorbell products that are less depending on single-choice clouds:

Er bestaan er minimaal eentje; smart deurbel met camera en evt speaker, eigen intern netwerk, compatible met SIP (en video), zelf verantwoordelijk voor opnamen, etc. Enige nadeel is dan wel de prijs, het is een Duits kwaliteitsproduct, dus reken rond de 350 euro voor het absolute basismodel. Doorbird heet het; oa te koop bij Robbshop en CoolBlue of direct bij de fabiraknt’s website.

Nee hoor, ze hebben een LAN API: https://www.doorbird.com/downloads/api_lan.pdf?rev=0.25

Je moet je huis flink geautomatiseerd hebben wil je echt nut van die api willen hebben.

als je alles zelf in de hand wil hebben doe je dat ook. Je zorgt er zelf voor dat je webinterface via een externe URL bereikbaar is en dan is het enkel je eigen hardware en internetverbindingen die als SPOF dienen en je kan dan ook makkelijker van solution-provider wisselen zonder vast te zitten.

Microsoft subdomains

Posted by jpluimers on 2021/06/02

Almost every company I know has more than one subdomain, but while researching why support.microsoft.com could not be archived in the WayBack machine, I realised how many they have and bumped into a few sites listing most of them:

All via microsoft.com subdomains – Google Search.

Fritz!Box repeater and other devices: “Radar detection enabled. At the moment no wireless LAN connection (5 GHz) is possible; please wait.”

Posted by jpluimers on 2021/05/31

If any of your Fritz!Box devices under “Wireless” -> “Radio Channel” -> “5-GHz band”  the indicates “Radar detection enabled. At the moment no wireless LAN connection (5 GHz) is possible; please wait.” – Google Search:

  1. Click on the “Refresh Auto Channel” button
  2. Wait until it has chosen a new 5Ghz channel
  3. Verify you can connect over 5Ghz
  4. If you still cannot connect, retry steps 1…3 once.

I had this only happen on 1750E repeaters so far, but others seem to have had it on other Fritz!Box devices as well.

In the Netherlands, potentially affected channels seem to be 52 through 140.
