Thanks!

ipv6

Recently I noticed some people having extreme problems with some very simple and well know user interfaces:

1. Elevator in a train station. A woman touched the sign for up but not the button and was confused that nothing happened.

2. Door with standard door handle in another train station. A man was completely confused that the door didn’t open automatically and needed some time to figure out how to open the door.

And those people are supposed to operate something more complex like a computer?

WTF

I just found a Cisco bug in 12.4(20)T1: The ipv6 command is working on the wireless interface. This is fixed in all other version I tried including 12.4(24)T3, 15.0(1)M3 and 15.1(2)T. Who wants to use IPv6 over wireless LAN anyway?

Cisco, ipv6

You can find some training materials here.

At the August meeting sage@guug Berlin we’ll also have a talk about Cisco Nexus.

Cisco, networking, sage@guug

Yes I’m still alive but I was quite busy finishing some projects and working on some others.

I promise to post more frequently in the future.

ipv6

And another German provider offers IPv6. According to their wiki (German) you can get a /64 from Hetzner. I’ll give it a try. I think RDNS ist not possible yet.

ipv6, networking

As you might know IPv6 uses it’s own Ethernet type 0x86dd. You can use this easily capture only IPv6 traffic with wireshark just uses eth.type == 0x86dd as filter.

I think now it’s the time to cut back on food and drink. At least outside of my home. No, I don’t have sudden religious encounter, it’s just that there are quite a lot of people who want to watch 22 people running after on innocent ball .

It looks like a month without going out for food and drink because of all those crazy people. We just tried and they relay protested when we wanted them to turn the noise (and video) down.

Well on the positive side more time to finish my book and loose a couple of kilos.

I relay like using your search engine. Today I noticed that www.google.com shows some rather ugly background pictures. There is an option to change the background picture but this seems to require a google account. I hope this is only temporary. I don’t want an account.

BTW: WTF did you smoke to come up with this idea?
