CUPS error in Slackware 12
 

Hello,

My printer was working fine until one day, it stopped working :(, its a Canon PIXMA iP1600, here is the error log
The odd thing is, it had that error before in the log and it worked fine, any ideas?

well printers are desinged to fail.....ink dries up....heads get clogged so it could be a hardware issue = dead printer.

2) have you opened a web browser and just gone into address
localhost:631......if cups service is enabled and listening....you should get the cups home page...then click on printers and see what it reports

Well, typically thing don't just happen out of the blue like that (except of course hardware failure, but that's the last thing to assume). Did you do anything before this happened ? Upgrade anything, change anything ?

No, cups is not running because of that error, I should have made myself more clear, my bad

Well the last major thing I did before that is upgrade dropline gnome, but I remember printing stuff after I did that, so I doubt that is the problem

I doubt that it is a hardware failure because that shouldn't stop cups from running, AFAIK

ok with root powers go into
/var/run/cups/certs and see if you have a file, mine is called 0 (zero) and has a string
BE3F54183E87C68EC26E86A5748A77D2

2) I disagree on your assertion that cups is not running.

did you try to connect to it as.your third last line shows cups is listening on localhost
I [19/Feb/2008:16:02:32 -0800] Listening to 127.0.0.1:631 on fd 0

3) also look at /var/run/cups I have a file called 'cups.sock' which is the socket file.

1) Yes I do have a file in there and its 21E65052089F9759C254FCD8409945D6
2)I cannot connect to localhost:631
3)yes I have a file called cups.sock in /var/run/cups

"ps -e | grep cupsd" to see if cups is in fact running.

Brian

root@darkstar:/var/run/cups# ps -e | grep cupsd
root@darkstar:/var/run/cups#

/etc/rc.d/rc.cups start

What error messages/log messages?

Brian

yeah good one Brian

plus did you make any changes to your firewall, I still think cups is listening but you can not get to it.

just found this which may be useful for slackers

http://www.linuxquestions.org/questi...563#post390563

bash-3.1# /etc/rc.d/rc.cups start
cups: started scheduler. [ OK ]
bash-3.1#
the log messages I posted in post #1

I have not made any changes to my firewall that I can think off, I change my router configuration recently but the router shouldn't effect it and this was after this started happening

should give at least the loopback ......127.0.0.1 and maybe the ethernet device.

ok thanks for that, your local is the same as mine, I use wired ethernet and you have wide lan I assume.

lets go back to your cups error.

try
http://localhost:631/

http://h1.ripway.com/aus9/cups.png

then re-run ifconfig with root powers and your counts should increase.

EDIT

I mean the TX and RX should increase and have no errors

2) Can you name your firewall please and with some firewalls you can see their rulesets.

ok while waiting I had another look at my /etc/cups/cupsd.conf

do you have these lines?
# Only listen for connections from the local machine.
Listen *:631
Listen /var/run/cups/cups.sock

then when I read authenication lines I remembered that I set mine up to allow all users, so maybe you need to
su
issue web browser command eg firefox, opera, konqueror
then in address try
http://localhost:631/

1) Yes they do increase
2) I just use the firewall provided by my D-Link wireless router, I don't think the router would affect connecting to myself though, considering I could connect to localhost:631 before

Yes, I do have those lines, except it says localhost:631, and I can't connect to it even when running a web browser as root.

1) good to hear you could previously connect to localhost

2) have not researched your diffenent cups file but I am interested in that you have no software firewall and have a router firewall.

I am now thinking, even tho I have a diff router, maybe you can look at those settings eg
http://h1.ripway.com/aus9/router1.png
http://h1.ripway.com/aus9/router2.png

it does not take much to close off the web browser itself, I found out. So maybe, you can re-check your settings?

3) EDIT....oops I also meant for you to look deeper into your cups file at the authentication

# Restrict access to the server...
<Location />
Allow @LOCAL
Order allow,deny
Allow localhost
</Location>

ok a quick look at
http://www.cups.org/documentation.ph...upsd-conf.html

can you post your full cups conf file please?

2) the other thing you could try is backup your file and use mine?
http://h1.ripway.com/aus9/cupsd.conf

but you will need to stop and restart this service

2) well it worked the day or a couple days before and I know for a fact that no-one touched the router settings in that span, so I don't think the router is doing anything

3)I changed it do look exactly like that and no dice

I have just done some edits FYI.

and in case you have a home network see if this helps?

in case you have changed your hostnames try this...as other info as well

CUPS config file
Ya, I have reloaded cups after changed the config file
looking at those links now

some more lite reading for u

http://www.linuxquestions.org/questi...53#post3035253

I know u use slack and so unlikely to use Selinux but a number of distros have similar security tools...apparmor....bastille.....so you may be growing tired of me, but did you install or config any of these beasts?

ok my last thoughts while I wait for any replies

Mandriva to the rescue of slack!!!
http://mandrivausers.org/lofiversion...hp/t40639.html refer last post the long one.

or second best??
http://www.linuxquestions.org/questi...317/page2.html

read the lot sorry

I have not installed any apparmor or SELinux or anything like that
