Yes cupsd is running:
$ ps -auxw | grep cups
haines 28191 0.0 0.0 6560 3416 pts/6 S+ 05:21 0:00 nano cupsd
haines 29295 0.0 0.0 6180 664 pts/15 S+ 06:51 0:00 grep cups
On other hand,
# cupsd -h
-bash: cupsd: command not found
# cupsd
-bash: cupsd: command not found
I initially went to localhost:631. But I find that going to it displays
the CUPS web page, but I cannot open the Administration tab without
getting "Unable to Connect". When I try the URI I cannot even connect
to the Web intefac. This is probably a clue, but I don't know how to
intepret it.
I supplied root and root's pw when asked. This was several days ago
and until yesterday I used the Web inerface without a problem.
Can't retrace my steps at this point, but I belive I went to
Administration amd for my printer and selected it to be default.
It status shows it to be default, but yesterday it mysteriously
ceased to be default:
$ lpstat -d
no system default destination
So I do:
# lpadmin -d HP_LaserJet_1320_series
lpadmin: Unable to connect to server: Bad file descriptor
I look at /etc/cups/cupsd.conf and off hand see nothing odd.
For example:
Port 631
Listen /run/cups/cups.sock
Share local printers on the local network.
I suppose an obious thing to would be to purge and reinstall CUPS,
but I'd rather fix the problem than run around it. On-line discussaions
often presume systemd, which is no help.
There is no file /etc/cups/client.conf
The file /etc/cups/cupds.conf does not have the line "hostnamelookups"
It has
<Location />
# Allow shared printing...
Order allow,deny
Allow @LOCAL
</Location>
Should it be Order deny.allow ? should I change to Allow from all ?
When I run ~$ nc -zv <hostname> 631 I get Connection refused
# service cups start
# service cups status
$ lpstat -t
scheduler is not running
no system default destination
