DDNS+Bind

[Alexander Widera]

Hiho,

I have a running nameserver ...
I searched and found for example that:
http://ops.ietf.org/dns/dynupd/secure-ddns-howto.html
but i don't get it running...
I want to update (for example with dynsite) a domain (entry is on my
nameserver)...

What have I to do? What's that with the keys? TSIG and SIG(0) ... and where
shoud I place them?
Has someone a complete example?

Many thanks....
Alex
