	For 'localhost' in pointing the browser at its own machine. 

	This is a vexed question here. I've given all the machines names, 
in hope of better telling them apart under ssh and scp. My router, 
however (a Netgear MBR 814, from my local access provider) sometimes uses 
the names and sometimes does not, in displays for me to read; I can't 
tell what it says to the machines about one another, so I tried things it 
might be saying.

	Yes, I did know that much; and what I seemed to be seeing was a 
failure of it. Hbsk went looking for localhost, translated that into -- and them failed to find it. So I thought it might have 
better luck starting from 'Hbsk'; it was an easy thing to try.

	When I first started using names, I hoped that might be an 
additional benefit; I'm glad to hear it may, indeed.

	Incidentally, CUPS on *some* machines seems to be doing another 
strange thing. When I tell it with Firefox to delete a printer, or make 
on default, or whatever, Firefox opens a tab (labelled 426) telling me I 
now have to use https with some other machine's IP, 192.168.x.y; it lets 
me click on it; and then the whole tab goes blank. 

	Looks to me as if it's trying to delete an unwanted printer not 
from its own printers.conf (which I know from the command line doesn't 
have it anyway) but from the other machine it imagines that printer to be 
attached to. (It isn't.)
