Installing as a LAN -> WiFi bridge: FRITZ!WLAN Repeater 1750E

Posted by jpluimers on 2019/01/21

I have a bunch of [WayBackFRITZ!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).

  1. Connect the FRITZ!WLAN to your LAN
  2. Connect the FRITZ!WLAN to power
  3. Connect your laptop to the WiFi SSID FRITZ!WLAN Repeater 1750E with password 00000000 (that eight times a zero)
  4. Set your laptop with a fixed IP address 192.168.178.127 with netmask 255.255.255.0 and gateway 192.168.178.2 for WiFi.
  5. Connect to your FRITZ!WLAN at http://192.168.178.2
  6. Setup your FRITZ!WLAN for the first time (password, country) and have it reboot
  7. Logon to the FRITZ!WLAN
  8. Change the WiFI password and the SSID for 2.4 Ghz and 5.0 Ghz channels (I use a different SSID for both as many Fritz!Box devices have both bad 2.4Ghz performance and a hard time to automatically switch from 2.4Ghz to 5.0Ghz on the same SSID automagically).
  9. Change your laptop to use DHCP on WiFi
  10. Reconnect to the Fritz!Box with the new SSID and password

Raspberry Pi cannot be woken up by WOL, but it can send, and there is Whack-on-LAN

Posted by jpluimers on 2019/01/17

Cool stuff if you want to make your own WOL devices out of spare parts.

From old to new:

They can be woken up by anything sending magic WOL packets, including Raspberry Pi (which cannot be woken up by them, though you could use a Whack-on-LAN for that).

Basically the Raspberry Pi cannot be woken up with WOL because of a few reasons:

  1. The ethernet chip is connected over USB so it cannot pass the WOL result further on.
  2. If it could, there still is no BIOS to process the WOL result.
  3. When it is halted but has power, the CPU isn’t active. The GPU is, but cannot process the WOL.

It can be a WOL server though: [WayBackRaspberry Pi As Wake on LAN Server: 5 Steps (with Pictures)

Tools for TCP tunnels over HTTP/HTTPS

Posted by jpluimers on 2019/01/16

With the advent of WebSockets, it looks like TCP tunnels over HTTP/HTTPS are gaining more ground and I need to put some research time in them.

Some old to new links:

CONNECT requests are not supported by many HTTP proxies, especially in larger organisations, so chisel and crowbar have a much bigger chance there.

And of course there is SoftEtherVPN/SoftEtherVPN: A Free Cross-platform Multi-protocol VPN Software. * For support, troubleshooting and feature requests we have http://www.vpnusers.com/. For critical vulnerability please email us. (mail address is on the header.).

However, that is a VPN solution which is much broader than just a single TCP tunnel. You can so similar things with OpenVPN, but over HTTP/HTTPS, also requires CONNECT:

SoftEtherVPN seems to be more versatile though. I blogged about that before, but back then didn’t have needs for it yet. VPN over HTTPS: Ultimate Powerful VPN Connectivity – SoftEther VPN Project.

Reminder to self: see how widespread support for the TCP BBR congestion control algorithm is.

Posted by jpluimers on 2019/01/14

The TCP BBR congestion control algorithm was introduced in September 2016 and became available in Linux kernel 4.9 in July 2017 after being in the news for a good 5 months (see links below). It strives for better bandwidth use and lowering latency on big data pipes.

This post is a reminder myself to see how widespread that is on recent distributions for both end-user and server systems.

Strange MAC addresses starting FA:8F:CA without OUI in your network? They are Locally Administered Addresses and likely from Google.

Posted by jpluimers on 2019/01/07

A while ago, I write about Locally Administered Addresses: a few series of MAC addresses you can use on your local network: MAC address ranges safe for testing purposes (Locally Administered Address).

A while ago, I found ones in my network and ones in my WiFi SSID survey starting with FA:8F:CA. They did not show up in the Wireshark · OUI Lookup Tool nor their manufacturer database.

But with bit 7 turned off they start with F8:8F:CA which does show up as “F8:8F:CA Google, Inc.”

They appear to be Google devices, in my case Google ChromeCast ones, though they can also be Google Home ones.

Google does “magic” with networks, just look at a few of the links here:

Need to play with this: Raspberry Pi web simulator from Microsoft Corporation

Posted by jpluimers on 2018/12/26

It’s been a while since [WayBack] +Microsoft Corporation has recently released a preview version of an open source +Raspberry Pi web simulator where you can connect sensors and component… – Jean-Luc Aufranc – Google+

Back then it was convoluted to get going. Hopefully by now that has changed.

So time to take another look during the holiday season:

Reminder to self: not all 4K displays are equal at HDMI: watch the HDMI version they support.

Posted by jpluimers on 2018/12/17

Experience from a friend:

The cause is that the Samsung only does 60Hz on DisplayPort because they do not support HDMI 2.0.

Not sure when this happened but the CIDR list is no more [WayBackhttps://www.whatsapp.com/cidr.txt:

Dear partners,
Please note that we have migrated the latest IP pools of WhatsApp to Facebook Mobile Partner Portal. Feel free to browse to the Settings page of the portal and download the latest WhatsApp IP pool: https://fb.me/mpp_support 
Further IP pool updates are also done through the portal and are no longer distributed via email or through WhatsApp web site.
If you have not yet registered on the Mobile Partner Portal or have difficulties accessing it - please request access through the following form and we'll be happy to assist: https://fb.me/mpp_access

In the past it was the place to get the CIDR so you could either block or allow WhatsApp traffic: [earlier WayBack]

It is still widely cited as way to regulate WhatsApp traffic, for instance at these places:

Anaylizing PDF files

Posted by jpluimers on 2018/12/10

A few things that failed/worked:

I still need to look at the Multivalent.jar when I have a system with Java again, as it is mentioned in [WayBack] pdf generation – Is there a tool to analyze a PDF in terms of fonts, objects, fields and their respective size (kb)? – Stack Overflow
