Trouble with cups

okos · 02-03-2009, 11:52 PM

Hi

I am using slack 12.2
I do not seem to be able to run cups

I tried http://localhost:631/ and it does not load.
I reinstalled cups.
chmod +x /etc/rc.d/rc.cups
I tried /etc/rc.d/rc.cups start
and
/etc/rc.d/rc.cups restart

I am not sure what else to do.

edit
ps ax | grep cupsd has the following results

Quote:

2875 ? Ss 0:00 /usr/sbin/cupsd
3477 ? Ss 0:00 cupsd
3525 ? Ss 0:00 cupsd -l
10679 pts/1 R+ 0:00 grep cupsd

Hello,

What is the error message when you try to load http://localhost:631/?

There's a tip in Alien Bob's wiki on cups:

Quote:

If localhost does not work for you when you type the URL in the browser, try the IP address for localhost which is 127.0.0.1. The URL would then look like this: http://127.0.0.1:631/. But in any case, this would indicate that you messed up your /etc/hosts file which should contain (among others) the line

127.0.0.1 localhost

If that line is not present, you should add it. It's absence will break quite many network services.

This is what I get...

Quote:

NETWORK TIMEOUT
The server at 127.0.0.1 is taking too long to respond.

/etc/hosts has
127.0.0.1 localhost

/etc/cupsd.conf is the generic version

Perhaps there is a problem with loopback

Quote:

nmap 127.0.0.1

Starting Nmap 4.76 ( http://nmap.org ) at 2009-02-04 20:15 PST
Note: Host seems down. If it is really up, but blocking our ping probes, try -PN
Nmap done: 1 IP address (0 hosts up) scanned in 2.15 seconds

perhaps this could also be the issue
I added the following to fstab to access the slackware iso.
/backup/slackware-12.2-install-dvd.iso /iso users,iso9660 ro,loop,auto 0 0

Then run "/sbin/ifconfig lo" to see if it's set up.
If lo is ok, run (as root) "iptables -L" to see if it's blocked by firewall.
If not blocked, run (as root) "netstat -apn | grep :631" to see that cups is listening for connection.

GOOD POINT!
I should have thought of that

.
I think the issue it that I removed execution for
/etc/rc.d/rc.inet1
I had setup rc.inet1.conf for eth0 and ath0, but it took up quite a bit of time when booting.

I started to use wicd because of its ease of use when changing networks.

Perhaps I need to comment out the interfaces in rc.inet1.conf instead of disabiling rc.inet1

or perhaps a better way is to add iwconfig lo up to rc.local

BTW, when you add a printer, what file is the info stored?
