Greets to all.

I'm trying to setup my first printer using cups, and from what I've read, cups can be administered by navigating to http://localhost:631. Unfortunately, everytime I try this, my browser (Konqueror) returns:

An error occurred while loading http://localhost:631:
Connection to host localhost is broken.

I've also tried using the add printer control within YaST to no avail, when attempting to detect the printer YaST just hangs at around the 50% complete mark and doesn't budge. At this point, system performance is degraded severely.

I've also checked that I have cups installed properly using rpm -qa | grep cups which returns:

cups-drivers-stp-1.1.23-11
cups-drivers-1.1.23-11
libgnomecups-0.2.2-0.2
cups-libs-1.1.23-21
cups-SUSE-ppds-dat-1.1.20-106
gnome-cups-manager-0.31-3
cups-1.1.23-21.2
cups-client-1.1.23-21

I also have the hplip software installed (for a hp printer) which I checked with rpm -qa | grep hp which returns:

hplip-0.9.4-4
hplip-hpijs-0.9.4-4

Any ideas on this one? The fact that I can't even access the cups admin through the browser is quite a concern, as every other online source documenting printer setup using cups assumes that you are able to access cups admin at http://localhost:631.

Many thanks,

first i would make sure the process is running
ps aux | grep cupsd
next i would see if its accualy listening on port 631
netstat -tuanp

Thanks for the super quick reply AAnarchYY.

ps aux | grep cupsd returns:

lp 6126 0.0 0.1 7184 3320 ? Ss 10:24 0:00 /usr/sbin/cupsd

1000 10148 0.0 0.0 2728 672 pts/0 R+ 11:15 0:00 grep cupsd

netstat -tuanp returns:

Any ideas?

hrm... looks as though cups is running and is listening on port 631, did you try accessing it with any other brouser than konqueror? like forinstance, firefox.

Just tried with Firefox and Epiphany to no avail, which don't even return any kind of error message like Konqueror does.

check your cupsd.conf file (/etc/cups/cupsd.conf)
under <Location /> make sure there is a line reading Allow From 127.0.0.1 and that it isnt commented
also, just for the hell of it, instead of looking for localhost, try 127.0.0.1

I checked cupsd.conf, everything between the location tags was as it should be. I also tried http://127.0.0.1:631 and the internal IP address of the my machine:631 to no avail.

Problem solved, I added the following to hosts.allow and now I can access cups web admin:

cupsd : 127.0.0.1 : ALLOW

While fussing in the cups web control page, I had unchecked "Advanced, Allow printing from the Internet", and suddenly my cups web control at http://localhost:631/admin stopped working. (I couldn't browse to this address).

Looking to see what had changed I found that in /etc/cups/cupsd.conf, and then inside the <location />...</location> tags, it had removed and replaced it with I reverted this change, and restarted the server with

and this fixed the problem, so I can now use the cups web server again.
