This is not a problem report in that my system appears to be running fine.
Its just that I like to know how these things work if anyone has the time
to explain it.

When installing SuSE 9.3 I leave the network settings to the default (set
everything via DHCP). this sets:
Host Name: linux
Domain Name: site

I am reasonably confident that these settings are not coming from the
router, they are the same even if I boot up connected to a different port
on the router, or even if the router is switched off.

Are there any advantages to setting the host name manually to a more
meaningful name?
If I were to connect two computers running SuSE 9.3 to the router would they
get different names?

As I'm still playing around with the system I have installed it a lot of
times, on one occasion I tried setting the host name to a fixed value (not
via DHCP) and this caused it to fail the network test and the network did
not work, any idea why this might be? Is it safe to change the host name
using YaST2 once the system is installed?

On another occasion I was having problems with the USB mouse, this ment that
I had to keep re-booting the computer, this caused it to no longer
automatically login to KDE, this looks like a bug reported in the release
notes. Do you know how I can reduce the chances of this happening again?

If you need any details of my system its here:

Thanks,
