CUPS does not work together with OpenSuSE 11.0

English Network/Internet
1

Hi Folks,

I have big troubles with cups.

I upgraded
from OpenSuSE 10.3 to 11.0

The basic problem might be a network problem.
After modifying the MTU from 1492 to 1500 as requested by the sysconfig messages,I have even troubles opening the URL: http://localhost

At Installing the Printer inside YaST results in an eror:

cups(File)DoRequest error client-error-bad-request

Any ideas?

Maybe it will not solve your problem, but CUPS is at http://localhost:631/

when I connect to
http://localhost:631
I get the error message…

404 Not Found

What is the problem…

what does ’ service cups status ’ (run as root) return? Is it running?

edit: http://localhost would not return anything if you don’t have apache (or other http daemon) running.
Cups runs it’s own little web service , but that’s only on port 631.

To double check, you can ping to localhost?

The statement (as root):

netstat -an | grep LISTEN | grep tcp

should give you (among others) a line:

tcp        0      0 0.0.0.0:631             0.0.0.0:*               LISTEN

else GRUB is not even running.

#ping localhost
indicates connection established
(
64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.192 ms
)

calling
#service cups status
Checking for cupsd: running

indicates that cups is running

when I use konqueror to show:

http://localhost

I get the error

"Beim Laden von http://localhost ist folgender Fehler aufgetreten:
Keine Verbindung zu Rechner localhost.

What is wrong???

Calling
netstat -an | grep LISTEN | grep tcp

gives…
tcp 0 0 127.0.0.1:6560 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:55555 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
tcp 0 0 :::22 :::* LISTEN
tcp 0 0 ::1:631 :::* LISTEN
tcp 0 0 ::1:25 :::* LISTEN

but if I use konqueror to fetch:

http://localhost:631

i get the error :

404 Not Found

this is not surprising, as

http://localhost

does not work either…

What is wrong…

The (german!) error message you posted said “no connection to localhost”. Is
the firewall running (usually is on default install), is there a port opened
for cups (631). If you used the printer setup module in yast, it should be
open, but it might have hiccuped.

Easiest way is to turn off firewall, again, found in the yast -> security &
users section.

http://localhost
contacts apache, if it’s not running, no pages will be found.

http://localhost:631
contacts the cups server. it has nothing to do with apache and serves pages
from it’s own private directories.

Hello All,

i solved the problem by brute force.

I reinstalled my OpenSuSE 11.0 completely new. The old root partition was deleted.

After freeing the the Cups Port in the Firewall,
I had no problem to get connected to
http://localhost:631

YaST was able to initialize the printer this time.

Thanks a lot for your help…

If you have manually configured your browser with a proxy this is probably a problem with proxy exceptions.

Try placing localhost in the proxy exception list of your browser.
