2018-12-04 Really ending a domain name and the web presence 10 months ago
On 25 december 2004 there was a special deal giving me the .info names and for free for the first year. Since that moment I kept the names registered and redirected all web traffic to the right version: So the deal worked from a 'selling domain names' perspective: Christmas is a bad moment to review the need for domain names, so the easy solution is to renew it. My decision to stop with these names was made in January 2018.

Traffic to the .info versions is very minimal. With the cost of the domain registration I decided to stop doing that and devised an exit strategy which would result in a domain name that attracts no traffic and is not linked to my other webprojects. On the next renewal date the domain will expire. I have done this before in a different context: when we ended the students personal webspace at

The solution is to start returing HTTP state 410 Gone for search engines while at the same time returning a somewhat user-friendly error page.

Relevant bit of apache 2.4 configuration:
<VirtualHost *:80>

	DocumentRoot /home/httpd/campwireless-expire/html

    <Directory "/home/httpd/campwireless-expire/html">
        Require all granted

    RewriteEngine On
    RedirectMatch 410 ^/(?!gone.html|robots.txt)
    ErrorDocument 410 /gone.html
The gone page is simple: It has an explanation for human visitors and a meta refresh tag to redirect the browser eventually. But to a search engine the status 410 on almost any url will give a clear flag the page is gone and should be flushed from the cache.

2016-06-02 Not filling my disk with .well-known/acme-challenge directories 3 years ago
Encrypt all the things meme I am slowly gaining trust in my Let's Encrypt setup and today I renewed my certificate. One thing I noticed on the first tries was that the whole process left me with a .well-known/acme-challenge directory in every website. Solution: use the options for a general configuration item available in Apache which is then inherited by all virtual hosts. So now I have in the general configuration in /etc/apache2/apache2.conf:
Alias /.well-known/acme-challenge/ "/home/httpd/html/.well-known/acme-challenge/"

<Directory "/home/httpd/html/.well-known/acme-challenge/">
        AllowOverride None
        Order allow,deny
        Allow from all
So now there is only one directory filling up with challenge-response files which is easier to clean out. I have seen filenames for challenge response with a - at the start so rm * started to complain.

The first complete change to https is on Camp Wireless, Wireless Internet access on campsites.

2015-03-27 Overly interested Amazon EC2 nodes 4 years ago
On Camp Wireless and The Virtual Bookcase I see the following pattern in the access logs:
2620:108:700f::36bc:aade - - [27/Mar/2015:13:27:11 +0100] "GET / HTTP/1.1" 302 298 "-" "curl/7.36.0"
2406:da00:ff00::36e2:d963 - - [27/Mar/2015:13:27:38 +0100] "GET / HTTP/1.1" 302 298 "-" "curl/7.36.0"
Constant requests, 2 or 3 per minute from Amazon EC2 IPv6 addresses just requesting the / using curl. Over the day I now see 1334 unique addresses with at most 5 requests from one url.

The same pattern as described in Stange stream of HTTP GET requests in apache logs, from amazon ec2 instances - Server Fault with no real answer to the why.

It's not a problematic amount of traffic, I'd just like to understand what is happenning!

2014-08-04 IPv6 visitor stats 2014 5 years ago
Time to count IPv6 visitor percentage to different websites again:
SiteJuly 2009July 2010July 2011July 2012July 2014 my homepage 1% 2% 2% 3% 4% hcc!pcgg netwerkgroep 2% 2% 2% 3% 1% weather maps < 1% 5% 6% 7% 6% BBS files 1% 1% 1% 3% the webcam < 1% 1% < 1% 2% 2% The Virtual Bookcase < 1% 1% 1% 4% 87% Camp Wireless < 1% 1% 1% 3% 70% Weather station Utrecht Overvecht 1%
Interesting numbers. Results for The Virtual Bookcase and Camp Wireless are totally skewed thanks to some IPv6 bot constantly checking the site from constantly changing IPv6 addresses .. but without privacy extensions enabled.

Method: unique IPv6 addresses seen in the whole month / total unique addresses seen in the whole month.

There is an interesting relation between 'website with technical subject' and 'visitors with IPv6'. I counted the number of unique addresses of visitors via IPv6 to several websites I run for the month of July 2010 and found the following percentages: Comparing it to July 2009 (percentages between parentheses) does show growth.

And it is back! Idefix 4 broke in a major way: the power supply let out the magic smoke in a big way: the hosting company called me to let me know the server was smelling funny and did not want to start up at all. Since the end of idefix 4 in a rack was near anyway the decision was made to move the server home. There I used another power supply to get access to my data again. The old powersupply was a 300 Watt powersupply which seems to be way underrated for a dual Xeon system. My best guess is that the instability the system had came from the powersupply anyway. So, time to move more domains home. Content from is now here at home and virtualbookcase will be next when I find time. I had started migrating Camp Wireless so I finished that migration fast. Mail is diverted to a different place so I have a bit of time to configure all the mailing lists and other things.

I played with Google Earth and it's fun and has lots of options. And lots of stuff you can play with, so after some websearches and looking at some samples I added google-earth links in Camp Wireless so you can lookup a campsite in Google Earth when it has a waypoint.

Ik zag een artikel op Wifi op de camping dankzij handig overzicht en de genoemde site zou in de toekomst misschien iets gaan doen met buitenlandse campings. Ik heb toen gemailed over Camp Wireless en ze hebben gelijk een link ernaar opgenomen in het artikel. Honderden bezoekers waren het gevolg, en een stuk meer aanmeldingen van Nederlandse campings met draadloze Internet toegang. Genoemd worden op levert geen zware slashdotting op, maar toch wel honderden bezoekers.

2006-02-17 (#) 13 years ago now lives on a new server, somewhat faster and more reliable. Time to update the picture on that page! I also moved stuff like The Virtual Bookcase and Camp Wireless. Only thing that gave me troubles right before moving was GNU mailman.

Doing some updates to Camp Wireless, finding campsites that advertise as having wireless Internet in the Woodall's guide... just added campsite number 400(!), Hot Springs National Park KOA in Arkansas, USA. It is funny to see the growth in campsites with wireless Internet access.

I'm becoming an RSS junkie both for reading and writing them. Using Sage within Firefox. So now Camp Wireless has RSS feeds for new forum posts and new campsites.

Interesting what you can see in a web access log: - - [23/Nov/2004:17:19:28 +0100] "GET /forum/viewtopic.php?t=12&highlight=%2527%252esystem(chr(105)%252echr(100))%252e%2527 HTTP/1.0" 200 15071 "-" "Mozilla/4.0 (compatible; MSIE 6.0b; Windows NT 5.0)". Guess phpBB has a problem...

2004-11-22 Camp wireless goes wap 14 years ago
Camp Wireless goes mobile. Wap browsers will find a lightweight mobile version of the directory of campsites at (this link will take you to the normal site in an html capable browser). This solves the chicken-and-egg problem of being somewhere and finding a campsite with wireless Internet, without having Internet. Programming for wap is interesting. There is only one wap-browser for Unix available, wApua but that one does not support forms. And stuff that looks ok in wApua fails horribly on my Nokia with the helpful error for any page it doesn't understand (including wml format errors): 'File format not understood'.

Round of Apache web server upgrades, with included PHP upgrade. Somehow Apache on FreeBSD still doesn't like to build shared objects, so the Apache on is statically linked again. Affected sites: The Virtual Bookcase, Camp Wireless,, Fight Spam on the Internet!.

Added more campsites to the directory of campsites at Camp Wireless. Now all the site needs is lots of visitors.

Added an ICRA rating to Camp Wireless. The site does not need a rating very hard, but it helps with access from webkiosks that are strictly configured.
