GExperts – when your predecessor has put it under the Tools menu

Posted by jpluimers on 2017/03/21

I totally forgot that GExperts can be under the Tools men

GExperts IDE configuration

GExperts IDE configurationu (I’m so accustomed that Alt-X is GExperts and Alt-M is ModelMaker Code Explorer).

These keyboard shortcuts are only assigned when you install GExperts before you install ModelMaker Code Explorer.

If you reverse, then you have to fiddle by removing the ModelMaker Code Explorer expert, then re-add it.

Anyway: you can configure this in the “IDE” tab of the GExperts Configuration.

After that you have to restart the Delphi IDE to reflect the change.

When a ScanSnap ix500 blinks an orange light/LED/button

Posted by jpluimers on 2017/03/20

Still not sure why (as the WiFi here didn’t change) but I had the LED of my ScanSnap ix500 scan button light up orange instead of blue.

Via How to Connect More than One Mobile Device to Your ScanSnap iX500 [WayBack], I found out it means this:

If the light is orange, go to the ScanSnap Wireless Setup Tool and check the mobile connection.

 

Evernote suggests to have it re-connect over WPS [WayBack] but in as WPS has big security issues this is not a good idea.

So I hooked it up over USB and re-registered it to the WiFi connection. You can do this from both a Windows PC and Mac:

configure your ScanSnap iX500 to a different router, follow the step-by-step instructions here [WayBack]

If I ever want to use it on Linux: it is possible to get it to work, see 12.10 – Does the ScanSnap IX500 work with Ubuntu? – Ask Ubuntu

Ctrl-T — www.voidtools.com • View topic – Everything window is ‘Always On Top’

Posted by jpluimers on 2017/03/17

If you use everything search from VoidTools, then don’t be surprised that pressing Ctrl-T makes it “Always On Top”:

Ctrl-T sets

Ctrl-T sets “Always On Top”

Of course this is not defined in “Tools” -> “Options”.

I forgot in which version this was introduced, as in the past I never stumbled over it on keyboards that have Ctrl and Alt reversed.

Sniffers, Packet Capture – PFSenseDocs – cool, as it uses tcpdump/Wireshark format!

Posted by jpluimers on 2017/03/13

I hadn’t done a lot with pfSense in the past, which I regret a bit since I discovered this really cool feature: Sniffers, Packet Capture – PFSenseDocs.

The coolness isn’t so much that you can capture packets, but that it’s compatible with tcpdump and Wireshark (which has become available natively for Mac like 2 years ago).

Which means that you can download captures and open them in Wireshark.

So it’s as easy as 1,2,3:

  1. Set-up the capture on your router https://a.b.c.d/diag_packet_capture.php and start it
  2. Stop the capture and download the file
  3. Open the file in Wireshark or convert it to text using tshark

Factory restoring a 3rd generation Apple TV was more cumbersome, but I learned about BlueTooth keyboard sharing from my Mac

Posted by jpluimers on 2017/03/03

Apple TV needs iTunes

Apple TV needs iTunes

A while ago, my model A1469 3rd generation Apple TV had a slowly blinking white light but nothing displayed over HDMI any more, so I searched for Apple TV slow blinking white and

Reading Restoring your Apple TV (when its white light is flashing) | Comics and gadgets, I opted for the first option: a soft-restart of the Apple TV. To do that you have to press menu+down on the Apple Remote at the same time for 5+ seconds, then wait for the Apple TV to restart. That initially did show an image over HDMI which later disappeared. I didn’t get the image at first as I thought it was looking for iTunes media over USB (like from an iPhone or iPad), so I waited for a time-out to occur.

After a while that image disappeared and the Apple TV white LED started rapidly flashing. Not good.

Later I found the image was portraying a USB cable not having a connection to an iTunes logo and some dark grey text on a black background pointing to support.apple.com/appletv/restore.

I didn’t see that at first as the room was a bit brightly lit since we had a lot of sun that day so this non-descriptive image with grey on black UX worked really well.

Conclusion: I had to restore the Apple TV which I thought would be straight-forward as it had been connected to my iCloud account.

The woods and trees of OpenSuSE on single-board computers – image abbreviations – and getting it installed using OS X

Posted by jpluimers on 2017/02/27

Finding the right image

There are many single-board computers on the OpenSuSE hardware-compatibility list (HCL), including:

A lot of them have ready to go images, often for Tumbleweed, however none of the pages explain the below image differences hence the one-line for each:

Since I wanted a headless system, JeOS was what I needed.

As it wasn’t available for my ODroid C1+ but was for my Raspberry Pi 2 and as my main machine is a 15″ Retina MacBook Pro Late 2013 [WayBack] below are the steps I used to get the image working.

Installing the Raspberry Pi 2 image using OS X

The below Raspberry Pi2 link will redirect to the correct image in the generic download directory http://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/RaspberryPi2/images/

http://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/RaspberryPi2/images/openSUSE-Tumbleweed-ARM-JeOS-raspberrypi2.armv7l.raw.xz

For other Raspberry Pi versions, you can find them here:

http://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/RaspberryPi3/images/openSUSE-Tumbleweed-ARM-JeOS-raspberrypi3.aarch64.raw.xz

http://download.opensuse.org/ports/armv6hl/tumbleweed/images/openSUSE-Tumbleweed-ARM-JeOS-raspberrypi.armv6l-Current.raw.xz

I installed on a 8 gigabyte SD card that revealed itself as /dev/disk1 using this diskutil command (via osx – List all devices connected, lsblk for Mac OS X – Ask Different [WayBack])

diskutil list

So this wrote the image to SD card in a sudo su - prompt:

targetDevice="disk2"
unxz --keep openSUSE-Tumbleweed-ARM-JeOS-raspberrypi2.armv7l-2016.08.20-Build2.1.raw.xz; \
diskutil umount "/dev/${targetDevice}s1"; \
dd bs=1m of="/dev/r${targetDevice}" if=openSUSE-Tumbleweed-ARM-JeOS-raspberrypi2.armv7l-2016.08.20-Build2.1.raw; \
sync; \
diskutil list; \
diskutil eject "/dev/${targetDevice}"

or if you want to select which image to “burn”:

targetDevice="disk2"
imageName="openSUSE-Tumbleweed-ARM-JeOS-raspberrypi2.armv7l-2016.08.20-Build2.1.raw"
imageName="openSUSE-Tumbleweed-ARM-JeOS-raspberrypi.armv6l-2016.11.23-Build2.22.raw"
imageName="openSUSE-Tumbleweed-ARM-JeOS-raspberrypi3.aarch64-2017.01.12-Build3.2.raw"
unxz --keep ${imageName}.xz; \
diskutil umount "/dev/${targetDevice}s1"; \
dd bs=1m of="/dev/r${targetDevice}" if=${imageName}; \
sync; \
diskutil list; \
diskutil eject "/dev/${targetDevice}"

A few notes:

Since I was talking about security anyway…. this is a nice toy for breaking open laptops or desktops when the administrator forbade the installation of software, or you want software on it executed. This is often the case with company devices, e.g. the laptops which are supplied by banks to their 3rd party suppliers. Outsourcing is cool, remember?

This is a computer on a stick which can run a Linux kernel. In combination with some USB gadget kernel modules, it can be configured to authenticate itself as any device. All you need to do is plug it in, and iterate by brute force through the device identifiers until you hit one which is accepted to be used. Store the statically linked software you want to install or run on the stick beforehand, and here you go. So if you ever need a SSH client on a “secure” Windows laptop… putty.exe FTW.

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 – via AVM International

Posted by jpluimers on 2017/01/23

This was a tad difficult to find as I searched for “Convert Fritz!Box to Switch” instead of “Convert Fritz!Box to Access Point”.

Since I had an old Fritz!Box 7360 lying around (from my ADSL era) and wanted to extend the cabled LAN for my brothers Fritz!Box 7490 with some low-bandwidth devices (max 100 megabit/second) I searched for Switch. My bad.

Oh I had to factory reset it as well as I forgot the management credentials. The AVM help on this is cumbersome: Loading the FRITZ!Box factory settings | FRITZ!Box 7360 | AVM International but the xs4all help includes a web-reset procedure as part of Internet: Reset procedures van mijn FRITZ!Box 7360 which translates to:

  1. Switch off the Fritz!Box (as this procedure needs to be done within 10 minutes of switching it on)
  2. Connect LAN2 to your computer
  3. Switch on the Fritz!Box
  4. Wait for a DHCP IP or (if you know the IP addresses) configure IP manually
  5. Go to the web-interface URL
  6. Indicate you forgot your password:

    Forgot your password?

    Forgot your password?

  7. Indicate you want a factory reset:

    Restore Factory Settings

    Restore Factory Settings

Anyway: with the above steps it becomes a Managed Switch (and if you don’t disable WiFi: Access Point too) that uses the primary internet connection as DHCP server (so it gets an IP address itself as well which means you can manage it).

linux port forwarding to external ip – Google Search

Posted by jpluimers on 2017/01/20

For my Link Archive via linux port forwarding to external ip – Google Search:

Need to look at this more closely, but it looks like you need PREROUTING, FORWARD and POSTROUTING and two NATs (DNAT and SNAT), as this graph from Port Forwarding Using iptables – SysTutorials shows:

PACKET IN
    |
PREROUTING--[routing]-->--FORWARD-->--POSTROUTING-->--OUT
 - nat (dst)   |           - filter      - nat (src)
               |                            |
               |                            |
              INPUT                       OUTPUT
              - filter                    - nat (dst)
               |                          - filter
               |                            |
               `----->-----[app]----->------'
