CUPS server cannot be contacted

(harlie · 01-21-2007, 02:02 AM

I am trying to install a printer onto my Zenwalk box. However after I enter the root password for the printer manager an error message comes up that reads "The CUPS server could not be contacted". I have downloaded and installed CUPS and that seemingly had no effect on my problem, and I'm fairly new to Linux and don't know what else to try. I am obviously doing something wrong, and any help would be greatly appreciated.

Thanks

(sorry about the wrong forum

first - check if the CUPS server started
use your service manager (not sure about zenwalk, this works on gentoo and debian-based)
#/etc/init.d/cuspd status

then check the port
#netstat -nap | grep 631
cupsd must LISTEN on 631'st port

then enter CUPS server serttings page (start your favourite brouser):
http://localhost:631
and check your printer settings etc... print test page and so on ...

As root type cupsd. Then in a web browser, type http://localhost:631 in the URL box. If this works, hit CTL+C on the terminal that you ran cupsd or kill -15 `pidof cupsd` and then find the init service file for cups and run it.

I've found the init file and ran it (or at least I think that I did, nothing viably happened) but http:\\localhost:631 doesn't come up. Though it worked fine when I ran the commands you gave me.

Use the following for /etc/cups/cupsd.conf.

Code:

It is http://localhost:631 not http:\\localhost:631. The above will provide support so other computers on your network can printer to your printer and find out the status of the job. It is a plain config, so you will have to edit it to make your setup secure.

You can also use the command line to install a printer by using lpadmin. Use lpinfo -v to find available printers.

is it, or is it not working?
