OK, I changed that one on this machine.

That one already had the name I wanted.

Two very odd things. First nano -w doesn't make it obvious to me
(though perhaps it should) how much is one line, how much another :
GNU nano 2.0.6 File: /etc/
hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost localhost
::1 localhost6.localdomain6 localhost6
I have no idea where that 6 comes from, nor what it's doing there.
Second, if I open Computer > Filesystem > /etc with nautilus, I
don't see hosts at all! The search button or search tool on my panel
finds 81 files whose name contains "hosts", one of which is indeed /etc/
hosts; but clicking on that does get it in gedit, which looks much the
same :
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost localhost
::1 localhost6.localdomain6 localhost6
Is what begins with "::1" really a different line, then, than the
127.0.0.1 line?
Also, it doesn't say not to edit that line, just not to delete
it. Do I want to change "localhost" (without the 6) there??

Thanks! I've got a feelin' I'm gonna need it ...
