100% v6

I think that would make a good marketing slogan!

My current v6 experiment involves seeing how much of the networking into a particular machine can I get to be over IPv6? The machine I have chosen runs a web application and also has a windows file share on it (via samba).

So far the application is mostly using v6 as web stuff is easy. Samba was also easy as long as the clients where v6 enabled.

Its now down to the little things. DNS over v6 is the latest thing I'm working on but getting strange errors as the resolver can not do reverse lookups on IPv4 embedded addresses. These look like:

::ffff:10.1.2.3

I get loads of resolver errors on these. Command line nslookup works for name to IPv6 but reverse lookups are problematic.

Backups might be a difficult one to get working as its a vendor I will have to consult who might not care.

We'll see how far I can get.

My long term goal is to have all my internal systems use v6 by default.

Here's hoping.

CCNA Security

Yeah, I've been suckered in but hey, can't be that hard if it's a CCNA right?

So the other day I ordered my book and booked my exam. I've now got two months to get my brain into CCNA Security land but this shouldn't be that hard 'cos most of it is familiar already.

Here's hoping I make it through.
