1: Check that Cups is actually listening on the network. Run this
command as root on the machine where the printer is:
netstat --inet --inet6 --listen --program --numeric | grep cupsd
Does it say "192.168.x.y:631" or "127.0.0.1:631"?
No, neither.
[root@Hbsk2 ~]# netstat --inet --inet6 --listen --program --numeric |
grep cupsd
tcp 0 0 0.0.0.0:631
0.0.0.0:* LISTEN 2526/cupsd
tcp 0
0 :::631 :::* LISTEN
2526/cupsd
udp 0 0 0.0.0.0:631
0.0.0.0:* 2526/cupsd
[root@Hbsk2 ~]#
(Btw, the formatting is bad here, too: I have to run fairly large
fonts in my gnome-terminal to be able to read with any comfort, alas!)
2: Do you have a packet filter ("firewall") on the machine
where the
printer is? Have you opened the IPP ports in the packet filter?
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.)
