how do I set the hostname, FQDN, in yast?
I ran yast => network devices => network services => hostname/DNS:

Is the hostname actually the FQDN arrakis.bounceme.net?
(Please note that I'm not running a publicly available web server or anything like that, just on the LAN. I only want to ensure that the hostname has been changed.)
uname shows:
linux-k7qk:~ # linux-k7qk:~ # uname -a Linux arrakis 3.11.10-25-default #1 SMP Wed Dec 17 17:57:03 UTC 2014 (8210f77) x86_64 x86_64 x86_64 GNU/Linux linux-k7qk:~ # While I'm not running arrakis as a publicly available web server, or anything like that, I want it set up for that eventuality. Perhaps just on the LAN.
The FQDN arrakis.bounceme.net is registered on noip.com as a host name; part of their free services. (No, that's not a plug for noip, well, it is in a round-a-bout way...)
