changing domain name
I'm running testing for amd64.
niels@debian:~$ hostname -a
debian debian debian.opasia.dk
I would like to change this to:
How can I do this with a simple command, so this would reflect the
whole system ?
When installing testing I was connected via a wlan router (D-link
DI-524), the installer suggested opasia.dk, my ISP provider,
which I (in my ignorance) accepted.
Is this possible without cutting my internet connection ?
Thanks for your time.
