May 22,1973 was the day the Ethernet concept was first outlined in a memo from the young Bob Metcalfe at PARC [...]
named-checkconf -z after making changes to your Bind configuration. And of course you should read the output and fix errors.
For lazy people like me make is pretty useful:
root@dns:/etc/bind# cat Makefile
Just type make and your configuration gets checked and if everything is in order Bind is reloaded.
Last week I gave a one day IPv6 introduction at a customer.
They are afraid of two things:
- Implementing IPv6 in there complex network which has grown over the years
- Not implementing IPv6
http://www.vyncke.org/ipv6status/ just came up at #denog over on IRCNET.
1. It feels good when a project you where involved in is relatively high in the list for Germany and all services (Web/ Mail / DNS) are green.
2. Many people will need consulting and training in the near future.
3. Whats so hard about IPv6 and DNS?
I’m afraid to ask a question because I can guess the answer.
The answer will be: “Because ICMP is evil!”
At the end of February 2013 (20th-23rd) I’ll be giving an IPv6 training at the Open Source School in Munich. (Language will be German).
I recently needed to reset a password on an older Cisco Router where the config register was set to 0×1.
According to Cisco documentation 0×1 means “Automatic boot up from ROM (IOS sw subset)”. It was not possible to interrupt the boot process to enter rommon mode. The solution is quite easy: Just send the break when the IOS is already booted. After that you can enter rommon, change the config register to 0×2142, reset the device and recover the password as usual.
According to this article (German) Hetzner a German ISP well know for selling dedicated servers is planing to charge more for IPv4.
The article states that they plan to charge between 2 and 5 Euro per IPv4 address.
Still thinking that there is time starting to implement IPv6?
