I’ve been using a few cloud storage / online backup providers for a while on Mac and Windows now, with the primary goals of
- being able to sync data between machines
- having a backup online
Here are some pros/cons. Read the rest of this entry »

Fake Internet Connectivity for your Lab (Tricking NCSI) – via: Canberra Premier Field Engineering
Posted by jpluimers on 2013/06/21
If you ever wondered why how in Windows – as of Vista – the NCIS (network connection status indicator) determines if you have a valid internet connection, it is pretty simple, as both these pages explain:
- What do Microsoft and NCSI have in common? | TechRepublic.
- Windows 7 Network Awareness: How Windows knows it has an internet connection « Super User Blog.
- Appendix K: Network Connectivity Status Indicator and Resulting Internet Communication in Windows Vista.
- Appendix H: Network Connectivity Status Indicator and Resulting Internet Communication in Windows 7 and Windows Server 2008 R2.
NCIS depends on the msftncis.com domain (link to the checks from IntoDNS) and is for supporting Network Awareness in applications.
The probing is done in this order: Read the rest of this entry »

Note sure what caused it, but others have had it in the past as well.
Other symptoms:
- br0 network becoming slower and slower on download speed (but not on upload speed; in the end I had 0.5 megabit downstream and 5 megabit upstream)
- br0 ping times twice as high as normal (around 30 milliseconds on SpeedTest.net in stead of 15 milliseconds)
- WiFi (especially 2.4: eth1) becoming impossible to connect to from new connections
- packet drops
I thought they were caused because of me experimenting with a Fonera 2100A -> TomadoUSB experiment, especially since my FON access point was limited to 1 megabit.
But as soon as other users started to use the LAN, I got speed complaints about the slowness.
I’ve been running the ASUS RT-N66U in Firmware Version 3.0.0.4.260 with Operation Mode:Wireless router for quite a while now, but I also noticed that it had rebooted itself recently, as the was Uptime 0 days 20 hours when I started digging in the log.
The worst I got:
| Ping (milliseconds) | Down (megabit) | Up (megabit) | WiFi connection to |
|---|---|---|---|
| 31 | 0.4 | 0.9 | ASUS RT-N66U: 2.4 Ghz |
Time for a Reboot to see if it gets any better.
Later:
After a reboot the situation turned to normal:
| Ping (milliseconds) | Down (megabit) | Up (megabit) | WiFi connection to |
|---|---|---|---|
| 16 | 90 | 10 | ASUS RT-N66U: 2.4 Ghz |
| 17 | 9 | 8 | Fonera: MyPlace |
| 17 | 3 | 1 | Fonera: FON_AP |
| 15 | 2 | 0.6 | Wireless-N 3G Router |
| 15 | 1.5 | 0.7 | RT N66U TomatoUSB 2.4 Ghz |

“same glue” dns: glue records
Posted by jpluimers on 2013/04/12
If you ever get “same glue” messages when checking your comains (a lot of sites fail this, see these intodns.com or viewdns.info searches), you might wonder what DNS glue is.
DNS glue is needed when you provide the NS and A records for a domain on a host within the domain itself.
From inside that domain, this works, but from the outside, nobody knows how to resolve servers in that domain.
You need to have the registrar of that domain put the glue A records for the nameservers, so from outside the domain, you can find the nameservers, and via the nameservers you can resolve other DNS entries in the domain.
A few more detailed explanations:
- Shane Madden explains this very well in his “What is a glue record?” answer on Server Fault
- The Wikipedia entryDNS Circular_dependencies_and_glue_records
- What Is A Glue Record – Domainmonster FAQ.

So you thought Google TiSP (Toilet Internet Service Provider) was an April 1st joke? Not in The Netherlands…
Posted by jpluimers on 2013/04/02
If you thought the 2007 Welcome to Google TiSP (Toilet Internet Service Provider) and the Google TiSP ACTUAL Installation – YouTube formed a great April 1st joke, then you have miscounted the futurists.
Found out a while ago, that in The Netherlands, a variation of TiSP was used to provide internet through the sewage system:
- July 18th, 2012, in the province Friesland, a glas fiber cable was put through the sewer system:
Frisian: Glêsfezelkabel troch rioel | Omrop Fryslân – Alle dagen nij!.
Dutch: Glasvezelkabel door riool | Omrop Fryslân – Alle dagen nij!. - Late 2012, plans were revealed to connect a few farms to glassfiber using the sewing system in early 2013:
Twents dorp krijgt glasvezel via het riool | IT Pro | Tweakers.
The Belgians and Germans seem to favour the water pipes over the sewer though:

- Bonn utility tests fibre installation through waterpipes – Telecompaper.

Wil je snel en betrouwbaar Glasvezel internet in De Aker? Meld je dan nu aan!
Posted by jpluimers on 2013/02/01
Gebied voor Glasvezel in de Aker
Op dit moment loopt er een inventarisatie of er Glasvezel internet in De Aker kan komen.
Zie deze kaart met het gebied.
Heb je interesse, meld je dan nu aan: De grens ligt bij 30% van de huishoudens op 21 April.
Word voor 21 April die grens niet gehaald, dan kan het jaren duren voor deze kans zich opnieuw voordoet.
Gaat het door, dan wordt de aanmelding omgezet in een contract.
Aanmelden gaat als volgt:
- Volg deze link Eindelijk. Amsterdam De Aker krijgt glasvezel – Reggefiber
(Reggefiber is het bedrijf dat fysiek de glasvezel aanlegt, de provider is degene waar je abonnement loopt) - Tik rechtsboven op de pagina je postcode, huisnummer en toevoeging in
- Bekijk de beschikbare providers en abonnementen
- Kies een provider en abonnement dat bij je bevest
- Vul de aanvullende gegevens in
- Bevestig je aanmelding
Wil je meer informatie van mensen die al Glasvezel in Amsterdam gebruiken? Bekijk dan dit forumonderwerp: Het grote Glasvezel in Amsterdam Topic – Internetproviders en Hosting – GoT.
Waarom internet via Glasvezel en geen ADSL of Kabel?
- snel voor zowel uploaden als downloaden
(kabel en ADSL hebben altijd een lagere upload dan download snelheid) - mogelijkheid om van provider te wisselen
(kan met kabel niet) - eigen servers bij de meeste providers toegestaan
(bij ADSL en kabel mag het alleen bij een zakelijk abonnement) - veel goedkoper dan zakelijk ADSL
(zakelijk: hoge up-time, meer IP-adressen, dure kanaalbundeling voor hogere snelheden)
Waarom is en grote upload snelheid belangrijk?
- online backup diensten worden steeds belangrijker
- bedrijven met een eigen server thuis
- even snel een groot bestand naar een klant uploaden
Naast alleen internet, is het ook mogelijk om andere diensten over Glasvezel te krijgen, net als bij kabel of ADSL.
Op dit moment zijn deze keuzes zijn mogelijk
- Internet
- Internet, TV en bellen

“Holland versus The Netherlands” a new video by C.G.P Grey – @cgpgrey
Posted by jpluimers on 2012/12/23
C.G.P. Grey just released a new video: Holland versus The Netherlands:
I love almost all hist videos at
my first encounter to his work was a similar video about the U.K., G.B, England, and a whole lot more:
While watching that I thought “someone should make a video about Holland, The Netherlands and the Dutch Kingdom”. Good to see he just did (:
Still on my wish list: a video on Europe, Schengen, The European Union and the Euro.

So I won’t forget: IPv4 private networks 10/8 (10.x.y.z), 172/12 (172.16-31.y.z), 192.168/16 (192.168.y.z) and 169.254/16 (169.254.y.z) (via: Private network – Wikipedia, the free encyclopedia)
Posted by jpluimers on 2012/11/26
So I won’t forget: below are IPv4 private network ranges that you can use behind your router.
Private networks:
- 10/8
(10.x.y.z) - 172/12
(172.16-31.y.z) - 192.168/16
(192.168.y.z)
Link-local network:
- 169.254/16
(169.254.y.z)
Network you should not configure yourself:
I tried finding statistics on the actual use of private networks, but couldn’t.
This is from my own experience:
- Link-local is used when DHCP is not available.
- Lot’s of routers use 10.0.0.x, 192.168.0.0, 192.168.1.0.
- VMWare Workstation and VMWare Fusnion use 192.168.x.y.
