Tomato by shibby – upgrade procedure and cfg backup | LinksysInfo.org
Posted by jpluimers on 2020/02/24
Reminder to self: [WayBack] Tomato by shibby – upgrade procedure and cfg backup | LinksysInfo.org:
I keep a text file with the changes I’ve made after a fresh install and I keep the file updated as I make changes.
Re-configuring the router after that takes a bit of time, but it is not that bad. Toastman’s method (here) noted above as well as the methods described here and here can also be used, but I haven’t tried them.
which references:
- [WayBack] Using QOS – Tutorial and discussion | Page 3 | LinksysInfo.org
You need to save a file somewhere on or off the router, with the following command from the command line.nvram export –set >config.txt
This outputs the complete setup in useable text form, each line beginning with “nvram set”. This means it’s ready to input to the router without having to add the “nvram set” to every line. You could do this by ssh or telnet.
NOTE – you can only restore the whole config file to the original router. To configure a different router you need to cherry pick the important lines (see below)
e.g.
nvram set clkfreq=480,240,120
nvram set wl0_country=AU
nvram set wan_domain=freewifi
nvram commit - [WayBack] Tomato RAF Releases | Page 18 | LinksysInfo.org
save off the results of nvram export –quote, ie:
Code:
nvram export –quote > nvram_clean
after erasing, then subsequent changes are easy to find later with:
Code:
nvram export –quote | grep -Fvf nvram_clean
While not quite as readable or cut and paste friedly as –set, –quote is script friendly with the advantage that all entries are always a single line. - [WayBack] I’ve created a command-line NVRAM cfg file parser | LinksysInfo.org
Decodes Tomato cfg files into JSON so they can be changed and compared against other backups. Encodes JSON-formatted Tomato cfg key/value pairs into the Tomato cfg format.

[WayBack] Solved: Stuttering Audio Streaming To Apple TV Via AirPlay – The Spotify Community:
Try to disable Wifi multimedia (WMM) from your router’s WLAN settings

TL;DR: Raspberry Pi models 1..3 become hotter and hotter under load; no housing gives best cooling.

How to change the control of a Somfy RTS roller blind from 2 to 1 remote – Projectionscreen.net
Posted by jpluimers on 2020/01/20
This procedure works for Somfy RTS motors to:
- removing an additional channel
- removing an additional remote
The trick is to have one remote/channel that you want to keep working as you need that one to initiate the deletion process:
- On the channel/remote you want to delete
- Test with the up/down button that it is indeed the one you want to delete
- On the channel/remote you want to keep
- Test with up/down button
- The Somfy RTS motor show now work
- Press the small button with a pen
- The Somfy RTS motor now should “wiggle”
- Test with up/down button
- On the channel/remote you want to delete
- Press the small button with a pen
- The Somfy RTS motor now should “wiggle” again
- Test with up/down button
- The somfy RTS motor should now do nothing
- Press the small button with a pen
- On the channel/remote you want to keep
- Test with up/down button
- The Somfy RTS motor show still work
- Test with up/down button

XW6600 WOL – stopped working on Windows 10 – my trusty APC PDU to the rescue
Posted by jpluimers on 2020/01/17
A long time ago I wrote in Mac/PC: sending Wake-on-LAN (WOL) packets « The Wiert Corner – irregular stream of stuff “I’ve succesfully woken up these machines: HP XW6600 running ESXi 5.1 ThinkPad W701U running Windows 7”.
The XW6600 have now been demoted to Windows 10 machines that I only need every now and then, so most of the time they are shutdown.
However, with the installation of Windows 10 however, they stopped reacting to WOL (Wake on LAN).
Per web-search results, I’ve tried all the permutations of the below settings to no avail.
Luckily, my trusty APC PDU AP7921 (and little sister AP7920) helped out: when setting the “Reboot Duration” to 30 seconds or more (so the power fully drains), it can be rebooted.
Note that since I bought these a long time ago, they have been replaced by these:
- AP7920 Rack PDU, Switched, 1U, 12A/208V, 10A/230V, (8)C13
- AP7921 Rack PDU, Switched, 1U, 16A, 208/230V, (8)C13
Firmwares:
- [WayBack] AP7xxx Switched & Metered Rack Power Distribution Unit Firmware Revision 3.7.4 AOS 3.9.0 – APC – Jordan
- [WayBack]Switched & Metered Rack Power Distribution Unit Firmware Revision 3.9.2 – APC – Jordan
Power usage:
- an XW66000 with 32 gigabytes of RAM and one hard disk takes between 0.6-1.2 Ampère of current, which at 230 Volt is 140-275 Watt.
- over one day that is between 3.4 and 6.6 kWh

How Douglas Engelbart Invented the Future | Innovation | Smithsonian
Posted by jpluimers on 2020/01/15
Two decades before the personal computer, a shy engineer unveiled the tools that would drive the tech revolution
Don’t read this as a historic piece, but as the potential we are still going to experience what was not just sketched by a true visionary in 1968, but also demonstrated back then: [Archive.is] How Douglas Engelbart Invented the Future | Innovation | Smithsonian.
I am including one of the pictures below by Christie Hemm Klok that shows how far Engelbart was ahead of his time: not his initial invention of an input device (the mouse) “chord” kind.
After that, read about his 1968 presentation: The Mother of All Demos – Wikipedia
Finally, watch the video below, well worth watching the more than one and a half hours.

CSL Bearware 302658 DCF clock manual
Posted by jpluimers on 2020/01/13
The manual for the CSL Bearware 302658 clock that uses the DCF77 signal is at [WayBack] Bearware_Manual-302658-20161220FZ004.pdf.
I like the relatively large 3.3 inch display and the blue background.
You can get the clock here:
- [WayBack] Bearware – Digital alarm clock with temperature display | DCF radio-controlled alarm clock / travel alarm | 3.3″ LCD display with blue LED backlight | Snooze function | Indoor | Date and day of the week display: Amazon.co.uk: Kitchen & Home

Some people still don’t know they should apply the Crucial Firmware Update For Crucial m4 SSD BSOD
Posted by jpluimers on 2020/01/10
Luckily I was watching over the shoulder of a friend when his hung as it was a while ago I had encountered issues like that.
Sometimes the system would get in trouble without warning: the machine would just hang. No Windows Event log or other place where we could trace back the origin.
I suspected failing hardware because it was similar to other machines I had seen: memory, loose connectors or power issues came to mind first.
After about a week of trial and error I decided to check SMART status. HDTune did not warn of anything special. SmartCtl however did:
This drive may hang after 5184 hours of power-on time:
http://www.tomshardware.com/news/Crucial-m4-Firmware-BSOD,14544.html
See the following web pages for firmware updates:
http://www.crucial.com/support/firmware.aspx
http://www.micron.com/products/solid-state-storage/client-ssd#software
The relevant links (I prefer the WayBack links as at times the site is very slow) are below.
After upgrading the firmware, the problems were gone.
- [Archive.is] Crucial Offers Firmware Update For Crucial m4 SSD BSOD
- http://www.crucial.com/support/firmware.aspx -> [WayBack] Support Pages | DRAM & SSD Drive Support | Crucial.com -> [WayBack] How to Install an SSD Solid State Drive | Crucial.com (which actually has the firmware links)
- The table is for the Crucial m4 2.5-inch SSD
| version | compatible products | download | ||
|---|---|---|---|---|
| 070H | Crucial m4 2.5-inch (7mm & 9.5mm) SSD | Windows® 7 Updater Application | Windows® 8 Updater Application | Manual Boot File for Windows and Mac® |
| Release Date: 04/02/2013
Firmware 070H is recommended for anyone currently running 040H or previous firmware releases. It includes incremental improvements and refinements over these versions which may improve the overall user experience. Like recent firmware versions, version 070H has improvements over versions 000F which are specific for Windows 8 and new UltraBook systems, although systems running Windows 7 and other operating systems may also see improvements. Any m4 firmware The following is a summary of changes between 040H and 070H, which are independent of operating system:
