1. it's the default config from debian - I have not changed it.
    (and it's commented out)

2. it was already explained that the problem lies elsewhere, my e-mail was 
even reply to that explanation. 

It looks like the CNAME doesn't work for dhcp-assigned names although it 
should according to the config snippet above.

however, one should first verify this.


I avoid problems of this type by defining:
- hostnames and IP addresses in /etc/hosts
- hostnames and MAC addresses in /etc/ethers

so the hostnames exist all the time.
