	No, neither. 

[root at Hbsk2 ~]# netstat --inet --inet6 --listen --program --numeric | 
grep cupsd
tcp        0      0 0.0.0.0:631

fonts in my gnome-terminal to be able to read with any comfort, alas!)

	How do I tell?

	I have whatever F9 defaults to; I've tried to disable SELinux, 
but not I think succeeded.

	Lacking the skills to be sure whether I've been cracked, let 
alone those to recover, I try to be paranoid; I install denyhosts, for 
instance, and likely other defenses that don't spring to mind.

	Also, the router that my ISP supplies (Netgear MBR 814) supplies 
several kinds of defenses, which I have tried to set with caution. When I 
want to do bittorrent, for instance, I have to go change the router 
settings for a while. (I try to leave them changed long enough to give 
back more that I take, before I change them back; but I haven't actually 
used the torrent in months, so they are probably tight.)
