I hate it if I have to use wireshark because some programmers are to stupid to provide some logging for the crappy peace of software they have written.

ping -i 30 www.quux.de somewhere between Frankfurt (Main) and Cologne on board the ICE last week. Some data is missing because there was some trouble with the wireless LAN on board (I guess the AP I was using rebooted and needed some time to recover, the other APs where to far away).

Just read the documentation for an IPS: a /24 (Class C) network.

Class full networking is dead for a couple of years and even if there still is class full networking in production somewhere a /24 in not necessarily equal to a Class C network as defined in RFC791.

The next meeting will be on April 29th, Dieter Klünter will be talking about free directory servers. The talk will be in German. See http://www.guug.de/lokal/nuernberg/20090429.html for details.

On May 11 I’ll be giving my usual presentation on IPv6 (again). This time in Munich. The talk will be in German, for details check http://www.guug.de/lokal/muenchen/.

ip addr del 192.168.200.200 dev eth0 is not a good idea when using this address to access the server.

When I’m giving a talk somewhere I’m used to some service from the organizers like hotel reservation, etc.

Well today I learned that this is not always the case. There are professionally organized conferences where you have to find your own hotel room and even have to register yourself for the conference. Okay, the organizers did send a promo code but the web form still wants your credit card data. Do I have to mention that the web form runs over http only?

The registration is running for quite some time now and as far as I heard they already have a lot attendees.

Update: After reading the source I noticed the the web form is a actually a frame using https embedded in the normal http page,
