ESXi 4.0.0.Update01-208167 Whitebox on HP xw6600: success!

Posted by jpluimers on 2017/05/19

Boy, I totally forgot to post this. It runs also ESXi 5.x; I’ve not tried more recent ESXi versions as they just run fine.

As a follow-up on [WayBackVMware Communities: ESX 3.5 Whitebox on HP xw6600 …, I have installed ESXi 4.0.0.Update01-208167 on a HP XW6600 workstation.

Good news: the generic ESXi 4 installation works, whereas the HP specific ESXi 4 fails (you get a nice purple screen of death).

Mikrotik – Choosing your SFP/SFP+ modules and direct access cables

Posted by jpluimers on 2017/05/09

For hooking up SFP and SFP+ ports on Mikrotik devices you basically have two options:

  • Direct Access Cable (passive and affordable for 1 and 2 meters; active and more expensive for more than 3 meters)
  • SFP/SFP+ modules with LC-LC optic fiber cable in between them (pairs of modules are more expensive than passive DAC, but the fiber is a lot cheaper)

Choosing the SFP/SFP+ modules is a bit intimidating as the MikroTik SFP module compatibility table – MikroTik Wiki has very few details.

Then I found sfp_all-150601132341.pdf (archived) which lists many of the SFP and SFP+ modules including their specifications.

Since neither the matrix nor the PDF contains links to the products, here is a small list of what I could source last year and is compatible with both the CCR1009 routeres and CRS226 switches:

Some links for MikroTik tips and scripts

Posted by jpluimers on 2017/04/25

MikroTik has great hardware, but getting things to work can be a bit ehm intimidating.

So here are some links that were useful getting my CCR1009 and CRS226 configurations to do what I wanted.

Very advanced stuff:

Packet flow (maybe the toughest part to wrap your head around):

Scripts:

Load balancing:

Syntax highlighting:

Pictures

Very well written blog:

Powering Raspberry Pi devices from a Fritz!Box USB connection

Posted by jpluimers on 2017/03/30

I tried to power both Raspberry B+ and Raspberry 2 B devices via the USB ports of both a Fritz!Box 7490 and Fritz!Box 7360.

At first this works, but the Raspberry B+ devices over time would become unstable: not being able to ping and/or boot.

So below are some links on power requirements and powering Raspberry Pi A, B, A+, B+, 2B and zero.

Fazit/TL;DR: use an external power supply when available.

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.
